# li_sentry_check

Multi-platform server inspection and health check via SSH.

## Security Declaration

**This skill is strictly read-only and does NOT:**
- ❌ Modify any server configuration
- ❌ Install or remove software
- ❌ Restart or stop services
- ❌ Write to any file on the remote server
- ❌ Exfiltrate data to external services
- ❌ Access local files other than: `references/targets.yaml`, `references/checks.yaml`, and the SSH private key specified in `keyPath`
- ❌ Make any network connections other than SSH to the target server specified in `targets.yaml`
- ❌ Execute arbitrary commands — only commands from `references/checks.yaml` are allowed

**This skill ONLY:**
- ✅ Reads system information via predefined read-only commands
- ✅ Generates a local Markdown/JSON report
- ✅ Connects to ONE remote server via SSH using the key specified in `targets.yaml`

## Overview

Read-only inspection of remote Linux hosts over SSH using a dedicated key.
Collects system metrics, service status, security events, and generates
a structured Markdown report with anomaly highlighting.

## Platform Support

| Platform  | Script          | Runtime    |
|-----------|-----------------|------------|
| OpenClaw  | `scripts/inspect.mjs` | Node.js 24+ |
| NanoBot   | `scripts/inspect.py`  | Python 3.10+ |
| Hermes    | `scripts/inspect.py`  | Python 3.10+ |

## Safety (Default Deny)

- **Only** run commands defined in `references/checks.yaml`
- **No** state-changing commands (no installs, no config edits, no restarts)
- **Only** SSH key authentication (no passwords)
- **BatchMode=yes** — non-interactive SSH only

## Config

- **Targets**: `references/targets.yaml`
- **Allowed checks**: `references/checks.yaml`

## How To Run

### NanoBot / Hermes (Python)

```bash
python3 scripts/inspect.py --target bogon --checks daily
```

### OpenClaw (Node.js)

```bash
node scripts/inspect.mjs --target bogon --checks daily
```

### Options

| Option     | Description                              | Default |
|------------|------------------------------------------|---------|
| `--target` | Target name from `targets.yaml`          | (required) |
| `--checks` | Check group: `basic`, `services`, `daily`| `basic` |
| `--format` | Output format: `markdown`, `json`        | `markdown` |
| `--output` | Write report to file instead of stdout   | stdout  |

## Check Groups

| Group      | Description                              |
|------------|------------------------------------------|
| `basic`    | Hardware resources: CPU, memory, disk, network |
| `services` | Service status and error logs (from targets.yaml) |
| `daily`    | Full inspection: basic + services + security + logs |

## Extending

1. **Add target**: Edit `references/targets.yaml`
2. **Add checks**: Edit `references/checks.yaml`
3. **Add check group**: Define new group in `checks.yaml`

## SSH Key Setup

```bash
# Generate key pair
ssh-keygen -t rsa -b 4096 -f ~/.ssh/li_sentry_check -N ""

# Copy to remote server
ssh-copy-id -i ~/.ssh/li_sentry_check.pub inspector@<SERVER_IP>

# Test connection
ssh -i ~/.ssh/li_sentry_check inspector@<SERVER_IP>
```

## Security Best Practices

- **Key permissions**: `chmod 600 ~/.ssh/li_sentry_check`
- **Host verification**: For production, pre-populate `known_hosts` instead of `accept-new`
- **Service names**: Only alphanumeric, hyphens, underscores allowed (validated before use)
- **Command allowlist**: Never modify `checks.yaml` with state-changing commands
- **Report handling**: Reports may contain system data — do not share publicly

## Report Output

Reports are generated in Markdown format with:

- **Summary section**: Overall health status, anomaly count
- **Anomaly section**: ⚠️ Highlighted issues requiring attention
- **Normal section**: Collapsible normal check results
- **Details**: Full command output for each check

## 🔒 Sicherheits-Best Practices

- **Schlüsselberechtigungen**: `chmod 600 ~/.ssh/li_sentry_check`
- **Host-Verifizierung**: Für die Produktion `known_hosts` vorab befüllen statt `accept-new` zu verwenden
- **Dienstnamen**: Nur alphanumerisch, Bindestriche, Unterstriche erlaubt (vor Verwendung validiert)
- **Befehls-Whitelist**: `checks.yaml` niemals mit zustandsändernden Befehlen modifizieren
- **Berichts-Handhabung**: Berichte können Systemdaten enthalten — nicht öffentlich teilen

## 🔧 Erweiterungsleitfaden

### Neuen Zielserver Hinzufügen

`references/targets.yaml` bearbeiten:

```yaml
targets:
  datenbank-server:
    host: IHRE_SERVER_IP
    port: 22
    user: inspector
    keyPath: ~/.ssh/li_sentry_check
    services:
      - mysql

## 🔒 Mejores Prácticas de Seguridad

- **Permisos de clave**: `chmod 600 ~/.ssh/li_sentry_check`
- **Verificación de host**: Para producción, pre-rellenar `known_hosts` en lugar de usar `accept-new`
- **Nombres de servicios**: Solo alfanumérico, guiones, guiones bajos permitidos (validados antes del uso)
- **Lista blanca de comandos**: Nunca modificar `checks.yaml` con comandos que cambien el estado
- **Manejo de informes**: Los informes pueden contener datos del sistema — no compartir públicamente

## 🔧 Guía de Extensión

## 🔒 Best Practice di Sicurezza

- **Permessi chiave**: `chmod 600 ~/.ssh/li_sentry_check`
- **Verifica host**: Per la produzione, pre-compilare `known_hosts` invece di usare `accept-new`
- **Nomi servizi**: Solo alfanumerico, trattini, underscore consentiti (validati prima dell'uso)
- **Whitelist comandi**: Non modificare mai `checks.yaml` con comandi che modificano lo stato
- **Gestione report**: I report possono contenere dati di sistema — non condividere pubblicamente

## 🔒 보안 모범 사례

- **키 권한**: `chmod 600 ~/.ssh/li_sentry_check`
- **호스트 검증**: 프로덕션에서는 `accept-new` 대신 `known_hosts`를 사전에 채우세요
- **서비스 이름**: 영숫자, 하이픈, 밑줄만 허용 (사용 전 검증)
- **명령 허용 목록**: `checks.yaml`을 상태 변경 명령으로 절대 수정하지 마세요
- **보고서 처리**: 보고서에 시스템 데이터가 포함될 수 있음 — 공개적으로 공유하지 마세요

## 🔧 확장 가이드

### 새 대상 서버 추가

`references/targets.yaml` 수정:

```yaml
targets:
  데이터베이스-서버:
    host: YOUR_SERVER_IP
    port: 22
    user: inspector
    keyPath: ~/.ssh/li_sentry_check
    services:
      - mysql
      - redis
```

### 새 체크 그룹 추가

`references/checks.yaml` 수정:

```yaml
checks:
  데이터베이스:
    description: 데이터베이스 점검
    commands:
      - id: mysql_status
        cmd: "systemctl status mysql --no-pager | sed -n '1,20p'"
        timeoutSec: 10
      - id: mysql_connections
        cmd: "mysql -e 'SHOW STATUS LIKE \"Threads_connected\"' || true"

## 🔒 Melhores Práticas de Segurança

- **Permissões de chave**: `chmod 600 ~/.ssh/li_sentry_check`
- **Verificação de host**: Para produção, pré-preencha `known_hosts` em vez de usar `accept-new`
- **Nomes de serviços**: Apenas alfanumérico, hífens, sublinhados permitidos (validados antes do uso)
- **Lista branca de comandos**: Nunca modifique `checks.yaml` com comandos que alterem o estado
- **Manuseio de relatórios**: Os relatórios podem conter dados do sistema — não compartilhe publicamente

## 🔒 Лучшие практики безопасности

- **Права на ключ**: `chmod 600 ~/.ssh/li_sentry_check`
- **Проверка хоста**: Для продакшена предварительно заполните `known_hosts` вместо использования `accept-new`
- **Имена сервисов**: Только буквенно-цифровые символы, дефисы, подчёркивания (проверяются перед использованием)
- **Белый список команд**: Никогда не модифицируйте `checks.yaml` командами, изменяющими состояние
- **Обработка отчётов**: Отчёты могут содержать системные данные — не публикуйте их публично

## 🔧 Руководство по расширению

### Добавление нового целевого сервера

Редактировать `references/targets.yaml`:

```yaml
targets:
  сервер-базы-данных:
    host: ВАШ_IP_СЕРВЕРА
    port: 22
    user: inspector
    keyPath: ~/.ssh/li_sentry_check
    services:
      - mysql
      - redis
```

### Добавление новой группы проверок

Редактировать `references/checks.yaml`:

```yaml
checks:
  база-данных:
    description: Инспекция базы данных
    commands:
      - id: mysql_status
        cmd: "systemctl status mysql --no-pager | sed -n '1,20p'"
        timeoutSec: 10
      - id: mysql_connections
        cmd: "mysql -e 'SHOW STATUS LIKE \"Threads_connected\"' || true"
        timeoutSec: 15
```

# li_sentry_check Skill 设计文档

## 概述

`li_sentry_check` 是一个跨平台服务器巡检技能，支持 nanobot、OpenClaw 和 Hermes agent 三大平台。通过 SSH 密钥认证登录远程 Linux 服务器，执行只读巡检命令，生成结构化 Markdown 报告。

## 架构设计

### 双引擎架构

| 平台 | 引擎 | 运行时 | 脚本 |
|------|------|--------|------|
| OpenClaw | Node.js | Node.js 24+ | `scripts/inspect.mjs` |
| NanoBot | Python | Python 3.10+ | `scripts/inspect.py` |
| Hermes | Python | Python 3.10+ | `scripts/inspect.py` |

### 文件结构

```
li_sentry_check/
├── SKILL.md                  # 技能说明文档（大脑）
├── _meta.json                # 技能元数据
├── references/
│   ├── targets.yaml          # 目标服务器配置
│   └── checks.yaml           # 巡检命令白名单
└── scripts/
    ├── inspect.mjs           # Node.js 实现（OpenClaw）
    └── inspect.py            # Python 实现（NanoBot/Hermes）
```

## 核心功能

### 1. SSH 密钥认证

- 使用 SSH 密钥对认证，禁止密码登录
- 支持自定义密钥路径
- 非交互式 SSH（BatchMode=yes）
- 连接超时保护（ConnectTimeout=8）

### 2. 巡检命令白名单

所有巡检命令在 `checks.yaml` 中定义，分为三组：

| 检查组 | 内容 |
|--------|------|
| `basic` | 硬件资源：CPU、内存、磁盘、网络 |
| `services` | 服务状态：systemctl status + 错误日志 |
| `daily` | 完整巡检：basic + services + 安全 + 日志 |

### 3. 动态命令生成

`services` 和 `daily` 检查组的命令根据 `targets.yaml` 中配置的服务动态生成：

```yaml
targets:
  bogon:
    services:
      - sshd
      - mongod
      - docker
```

自动为每个服务生成：
- `svc_<name>_status` — systemctl status
- `svc_<name>_errors` — journalctl 错误日志
- `svc_<name>_recent` — 最近日志（过滤异常关键词）

### 4. 异常检测与报告

报告包含异常关键词检测：
- failed, error, alert, critical
- WARNING, panic, segfault, oom
- killed process, no space, disk quota
- read-only, corrupt, timeout
- refused, denied, unreachable

报告结构：
```
# 🔍 Server Inspection Report
- Target: bogon
- Host: `YOUR_SERVER_IP`
- Overall Status: ⚠️ WARNING
- Anomalies: 3

## ⚠️ Anomalies (Priority)
### ⚠️ systemd_failed_units
...

## <details>View all check results (20 total)</details>
```

## 安全设计

### 只读原则

- 仅执行只读命令（whoami, uptime, free, df, ss 等）
- 禁止修改服务器配置
- 禁止安装软件
- 禁止重启服务

### SSH 安全

- 仅密钥认证，禁止密码
- BatchMode=yes 防止交互式提示
- StrictHostKeyChecking=accept-new 自动接受新主机
- ConnectTimeout=8 防止长时间挂起

### 命令白名单

- 所有命令在 `checks.yaml` 中预定义
- 不支持任意远程命令执行
- 每个命令有超时限制

## 使用方式

### NanoBot / Hermes

```bash
python3 scripts/inspect.py --target bogon --checks daily
python3 scripts/inspect.py --target bogon --checks basic --format json
python3 scripts/inspect.py --target bogon --checks daily --output report.md
```

### OpenClaw

```bash
node scripts/inspect.mjs --target bogon --checks daily
node scripts/inspect.mjs --target bogon --checks basic --format json
node scripts/inspect.mjs --target bogon --checks daily --output report.md
```

## SSH 密钥配置

```bash
# 1. 生成密钥对
ssh-keygen -t rsa -b 4096 -f ~/.ssh/li_sentry_check -N ""

# 2. 复制公钥到远程服务器
ssh-copy-id -i ~/.ssh/li_sentry_check.pub inspector@YOUR_SERVER_IP

# 3. 测试连接
ssh -i ~/.ssh/li_sentry_check inspector@YOUR_SERVER_IP

# 4. 配置 targets.yaml
# 更新 keyPath 为实际密钥路径
```

## 扩展指南

### 添加新目标服务器

编辑 `references/targets.yaml`：

```yaml
targets:
  server2:
    host: YOUR_SERVER_IP_2
    port: 22
    user: inspector
    keyPath: ~/.ssh/li_sentry_check
    services:
      - nginx
      - mysql
      - redis
```

### 添加新检查组

编辑 `references/checks.yaml`：

```yaml
checks:
  database:
    description: 数据库巡检
    commands:
      - id: mongo_status
        cmd: "mongosh --eval 'db.runCommand({ serverStatus: 1 }).ok' || true"
        timeoutSec: 20
```

# 安全事件日志调查助手

## 功能说明

基于 LLM 的安全事件日志分析工具，支持简要分析和详细分析两种模式。

## 安装

```bash
cd /root/.openclaw/skills/security-log-analyzer
pip install -r requirements.txt
cp .env.example .env
# 编辑.env 文件，填写 API Key
```

## 配置

编辑 `.env` 文件：

```bash
SILICONFLOW_API_KEY=sk-your-api-key-here
SILICONFLOW_BASE_URL=https://api.siliconflow.cn/v1
SILICONFLOW_MODEL=Qwen/Qwen3-8B
API_RATE_LIMIT=2
```

## 使用方法

### 方式 1: 交互模式

```bash
cd /root/.openclaw/skills/security-log-analyzer
python src/analyzer.py
```

### 方式 2: 文件模式

```bash
python src/analyzer.py /path/to/log.txt brief   # 简要分析
python src/analyzer.py /path/to/log.txt detailed # 详细分析
```

## 分析模式

- **简要分析**：快速提取关键信息（威胁等级、事件类型、建议行动）
- **详细分析**：深度分析攻击链、IOC 指标、缓解建议

## 限流保护

- 默认请求间隔：2 秒
- 429 错误自动重试（等待 10 秒）
- 单条日志超过 4000 token 自动截断

## 示例日志

查看 `examples/sample_logs/` 目录中的示例日志文件。

## 输出示例

```markdown
## 事件概览
- 事件类型：SSH 暴力破解
- 威胁等级：中
- 时间范围：2026-04-22 20:00 - 21:30

## 关键发现
- 来自同一 IP 的 150+ 次失败登录尝试
- 目标账号：root, admin, ubuntu

## IOC 指标
- IP: 192.168.1.100

## 建议行动
1. 封禁源 IP
2. 启用 fail2ban
3. 配置 SSH 密钥认证
```

## 核心功能

1. **日志分析模式**
   - 简要分析：快速提取关键信息（威胁等级、事件类型、建议行动）
   - 详细分析：深度分析攻击链、IOC 指标、缓解建议

2. **API 配置**
   - 使用 OpenAI 兼容 API
   - 支持 SiliconFlow 平台
   - 通过.env 文件管理密钥和配置

3. **限流保护**
   - 请求间隔控制
   - 批量日志分片处理
   - 错误重试机制

```

## API 配置

**SiliconFlow 配置**：
- Base URL: https://api.siliconflow.cn/v1
- Model: Qwen/Qwen3-8B
- API Key: 从.env 文件读取

## 分析模式

### 简要分析（默认）
- 事件类型识别
- 威胁等级评估（低/中/高/严重）
- 关键 IOC 提取
- 3 条以内行动建议

### 详细分析
- 完整事件时间线
- 攻击链分析（MITRE ATT&CK 映射）
- 所有 IOC 指标提取
- 详细缓解和修复建议
- 相关日志关联分析

## 限流策略

1. **请求间隔**：每次 API 调用间隔≥2 秒
2. **批量处理**：超过 10 条日志时分批处理
3. **错误处理**：429 错误时指数退避重试
4. **日志截断**：单条日志超过 4000 token 时自动截断

## 使用流程

1. 用户选择分析模式（简要/详细）
2. 输入或粘贴安全日志
3. 调用 LLM 进行分析
4. 输出结构化分析报告

## 输出格式

```markdown
## 安全事件分析报告

### 事件概览
- 事件类型：[类型]
- 威胁等级：[等级]
- 时间范围：[时间]

### 关键发现
- [发现 1]
- [发现 2]

### IOC 指标
- IP: [...]
- 域名：[...]
- 文件哈希：[...]

### 建议行动
1. [行动 1]
2. [行动 2]
```

## 安全注意事项

1. API Key 仅存储在.env 文件，不提交到版本控制
2. 日志内容不持久化存储
3. 敏感信息自动脱敏处理

## 预设配置（推荐）

为了简化使用，可以在 `~/.summarize/config.json` 中预设常用配置：

```json
{
  "model": "baidu/ernie-4.0-8k",
  "openaiBaseUrl": "https://qianfan.baidubce.com/v2",
  "openaiApiKey": "your-bce-key",
  "length": "xl",
  "language": "zh-CN"
}
```

## 使用示例

```bash
# 总结网页
summarize "https://news.ycombinator.com" --model qwen/qwen2.5-72b-instruct

# 总结 YouTube 视频
summarize "https://youtube.com/watch?v=xxx" --model deepseek-chat

# 总结本地 PDF
summarize "/path/to/file.pdf" --model glm-4-plus

# 指定输出长度
summarize "https://example.com" --length medium

# 输出 JSON 格式
summarize "https://example.com" --json

# 仅提取内容（不总结）
summarize "https://example.com" --extract

# 流式输出
summarize "https://example.com" --stream on
```

### Security Warning

⚠️ **Only scan systems you own or have explicit authorization to scan!**
- Unauthorized scanning may violate laws
- sqlmap tests should be used cautiously, may trigger WAF/IDS
- Use --safe-mode in production to avoid destructive testing

### Troubleshooting

#### Scan Timeout
```bash
# Increase timeout
python3 scripts/li_base_scan.py 127.0.0.1 --timeout 600
```

#### Disable Progress Bar
```bash
# JSON output or disable progress
python3 scripts/li_base_scan.py 127.0.0.1 --json
python3 scripts/li_base_scan.py 127.0.0.1 --no-progress
```

```

### 模型文件

```bash
# 语音识别模型
$FAST_WHISPER_MODEL_DIR/models--Systran--faster-whisper-tiny/
```

## 配置说明

### 飞书凭证

**方法 1: 环境变量**（推荐）

创建 `.env` 文件：
```bash
export FEISHU_APP_ID="cli_xxx"
export FEISHU_APP_SECRET="xxx"
```

**方法 2: openclaw.json**

```json
{
  "channels": {
    "feishu": {
      "enabled": true,
      "appId": "cli_xxx",
      "appSecret": "xxx"
    }
  }
}
```

**⚠️ 安全提示**：不要将凭证提交到版本控制系统！

### 自定义目录（可选）

在 `.env` 文件中配置：

```bash
# 模型目录（默认：$HOME/.fast-whisper-models）
export FAST_WHISPER_MODEL_DIR="/opt/fast-whisper-models"

# 虚拟环境目录（默认：技能目录/.venv）
export VENV_DIR="/path/to/venv"

# 临时文件目录（默认：/tmp）
export TEMP_DIR="/tmp"

# 日志目录（默认：技能目录/logs）
export LOG_DIR="/path/to/logs"

# OpenClaw 配置路径（默认：$HOME/.openclaw/openclaw.json）
export OPENCLAW_CONFIG="$HOME/.openclaw/openclaw.json"
```

### TTS 配置

```json
{
  "messages": {
    "tts": {
      "auto": "always",
      "provider": "edge",
      "edge": {
        "enabled": true,
        "voice": "zh-CN-XiaoxiaoNeural",
        "lang": "zh-CN"
      }
    }
  }
}
```

## 脚本说明

### fast-whisper-fast.sh

```bash
#!/bin/bash
# 语音识别脚本
export HF_ENDPOINT=https://hf-mirror.com  # 国内镜像
VENV_PYTHON="技能目录/.venv/bin/python"  # 由 install.sh 自动配置

# 用法
./fast-whisper-fast.sh <音频文件>
```

**输出格式**:
```
[0.00s -> 2.32s] 识别的文本内容
```

### tts-voice.sh

```bash
#!/bin/bash
# TTS 语音生成脚本
export HF_ENDPOINT=https://hf-mirror.com
VENV_PYTHON="技能目录/.venv/bin/python"

# 用法
./tts-voice.sh "文本内容" [输出文件.mp3]
```

### feishu-tts.sh

```bash
#!/bin/bash
# 飞书语音发送脚本
# 自动转换 MP3 → OPUS

# 用法
./feishu-tts.sh <音频文件.mp3> [用户 ID]
```

```

## 故障排查

### 语音识别失败

**问题**: 无法识别语音内容

**检查**:
1. 模型是否下载：`ls $FAST_WHISPER_MODEL_DIR/`
2. 虚拟环境：`技能目录/.venv/bin/python --version`
3. 网络：`export HF_ENDPOINT=https://hf-mirror.com`

### TTS 生成失败

**问题**: 无法生成语音文件

**检查**:
1. edge-tts 安装：`uv pip list -p 技能目录/.venv | grep edge`
2. 网络连接：Edge TTS 需要访问微软服务
3. 输出目录权限

### 飞书发送失败

**问题**: 语音消息发送失败

**检查**:
1. 凭证配置：`echo $FEISHU_APP_ID`
2. 音频格式：必须是 OPUS
3. 用户 ID 类型：使用 open_id

## 性能指标

| 操作 | 耗时 |
|------|------|
| 语音识别 (tiny) | ~8-10 秒 |
| TTS 生成 | ~3-5 秒 |
| OPUS 转换 | <1 秒 |
| 飞书上传 | ~2-3 秒 |
| **总计** | **~15 秒** |

## 最佳实践

### 语音质量

1. **录音环境**: 安静环境，减少背景噪音
2. **说话速度**: 正常语速，避免过快
3. **音频格式**: 飞书自动发送 OPUS 格式

### 文件管理

1. **定期清理**: 每天凌晨自动清理
2. **保留策略**: 保留最近 10 个 TTS 目录
3. **空间上限**: 100MB 自动清理

### 错误处理

1. **识别误差**: 允许用户文字补充
2. **发送失败**: 降级为文字回复
3. **超时处理**: 设置合理超时时间

## 扩展功能

### 添加新音色

编辑 `tts-voice.sh`:

```python
# 中文男声
communicate = edge_tts.Communicate(TEXT, "zh-CN-YunxiNeural")

# 英文女声
communicate = edge_tts.Communicate(TEXT, "en-US-MichelleNeural")
```

### 调整语速音调

```python
# 在 edge_tts 中调整
communicate = edge_tts.Communicate(
    TEXT, 
    "zh-CN-XiaoxiaoNeural",
    rate="+10%",   # 语速
    pitch="-5%"    # 音调
)
```

### 支持更多语言

修改 `fast-whisper-fast.sh`:

# ⚠️ 安全注意事项

## 1. 修复脚本风险

⚠️ **注意**: `fix-debug-leak.sh` 脚本会修改其他 OpenClaw 扩展的源码。

- 此脚本用于修复飞书/Q4Bot 的调试信息泄露问题
- 会修改 `/root/.openclaw/extensions/qqbot/` 等扩展
- **建议**: 仅在确认需要时使用，并在测试环境验证

## 2. 模型镜像

默认使用 `https://hf-mirror.com` 镜像下载模型。

- 如需使用官方镜像，在 `.env` 中设置：
```bash
export HF_ENDPOINT=https://huggingface.co
```

## 3. 凭证安全

- 优先使用环境变量设置凭证
- 读取 `openclaw.json` 时可能接触其他账户凭证
- 多 Agent 模式下会自动读取对应账户配置

## 4. 生产环境建议

- ✅ 在测试环境先验证
- ✅ 仔细审查所有脚本
- ✅ 使用环境变量存储凭证
- ✅ 定期更新依赖


FILE:FIX_DEBUG_INFO_LEAK.md
# 调试信息泄露修复报告

## 问题描述

用户收到消息包含调试信息：
```
（已发送语音回复）🎙️
在的！刚才的语法讲解听明白了吗？还是想继续学词汇？ 📎 /tmp/openclaw/tts-c2amg8/voice-1774185757820.mp3
```

## 根本原因

**文件**: `/root/.openclaw/extensions/qqbot/src/ref-index-store.ts`

**函数**: `formatRefEntryForAgent()`（第 290-335 行）

**问题代码**：
```typescript
const sourceHint = att.localPath ? ` (att.localPath)` : att.url ? ` (att.url)` : "";
// ...
parts.push(`[语音消息（内容: "att.transcript"sourceTag）sourceHint]`);
```

这段代码将**本地文件路径**注入到 AI 上下文描述中，导致 LLM 看到：
```
[语音消息（内容："在的！刚才的语法讲解..." - TTS 原文）(/tmp/openclaw/tts-c2amg8/voice-1774185757820.mp3)]
```

LLM 可能在回复中引用这个路径，导致调试信息泄露给用户。

## 修复方案

### 修改前
```typescript
const sourceHint = att.localPath ? ` (att.localPath)` : att.url ? ` (att.url)` : "";
parts.push(`[语音消息（内容: "att.transcript"sourceTag）sourceHint]`);
```

### 修改后
```typescript
// 移除 localPath 避免调试信息泄露给 LLM
// const sourceHint = att.localPath ? ` (att.localPath)` : att.url ? ` (att.url)` : "";
parts.push(`[语音消息（内容: "att.transcript"sourceTag）]`);
```

**影响范围**：
- ✅ 语音消息 - 不再包含本地路径
- ✅ 图片消息 - 不再包含本地路径
- ✅ 视频消息 - 不再包含本地路径
- ✅ 文件消息 - 不再包含本地路径

**保留的信息**：
- ✅ 文件名（如果有）- 帮助用户识别附件
- ✅ URL 域名（如果是公网链接）- 帮助用户了解来源
- ✅ 语音转录文本 - 帮助 LLM 理解语音内容
- ✅ 转录来源标签 - 帮助 LLM 判断可信度

## 修复验证

### 修改前 AI 看到的
```
[语音消息（内容："在的！刚才的语法讲解听明白了吗？" - TTS 原文）(/tmp/openclaw/tts-c2amg8/voice-1774185757820.mp3)]
```

### 修改后 AI 看到的
```
[语音消息（内容："在的！刚才的语法讲解听明白了吗？" - TTS 原文）]
```

## 额外优化建议

### 1. 清理现有缓存
修复后，现有的 ref-index.jsonl 文件中仍包含带路径的旧数据。建议：

```bash
# 备份并清理引用索引缓存
mv ~/.openclaw/qqbot/data/ref-index.jsonl ~/.openclaw/qqbot/data/ref-index.jsonl.bak
# 或
rm ~/.openclaw/qqbot/data/ref-index.jsonl
```

### 2. 重启 QQBot 扩展
```bash
# 重启 OpenClaw 或 QQBot 扩展，使修复生效
openclaw gateway restart
```

### 3. 重置对话（可选）
如果用户仍有调试信息，建议重置对话：
```
/new
```
或
```
/reset
```

## 相关文件

- `/root/.openclaw/extensions/qqbot/src/ref-index-store.ts` - 已修复
- `/root/.openclaw/extensions/qqbot/src/gateway.ts` - 无需修改（日志输出到服务器日志）
- `/root/.openclaw/extensions/qqbot/src/utils/audio-convert.ts` - 无需修改（内部使用）

## 测试建议

1. **发送语音消息** - 确认 AI 回复不包含文件路径
2. **引用历史消息** - 确认引用描述不包含本地路径
3. **发送图片/文件** - 确认附件描述只包含文件名

## 总结

**修复完成时间**: 2026-03-22 21:30  
**修复文件**: 1 个  
**影响功能**: 引用消息格式化（供 AI 上下文使用）  
**向后兼容**: 是（仅移除调试信息，不影响功能）

FILE:MULTI_AGENT.md
# 多 Agent 支持说明

## 概述

li-feishu-audio 技能已支持多 Agent 模式，可以根据不同的 Agent 自动使用对应的飞书账户凭证。

## 配置方式

### openclaw.json 配置

```json
{
  "bindings": [
    {"agentId": "coder", "match": {"channel": "feishu", "accountId": "coder"}},
    {"agentId": "writer", "match": {"channel": "feishu", "accountId": "writer"}}
  ],
  "channels": {
    "feishu": {
      "defaultAccount": "coder",
      "accounts": {
        "coder": {
          "name": "编程助手",
          "appId": "cli_a94ed64eb1f89bc0",
          "appSecret": "xxx"
        },
        "writer": {
          "name": "写作助手",
          "appId": "cli_a94980d5d9381bda",
          "appSecret": "xxx"
        }
      }
    }
  }
}
```

### 凭证读取优先级

| 优先级 | 来源 | 说明 |
|--------|------|------|
| 1 | 参数指定 | `feishu-tts.sh audio.mp3 user_id coder` |
| 2 | 环境变量 | `OPENCLAW_ACCOUNT_ID=coder` |
| 3 | 默认账户 | `openclaw.json` 中的 `defaultAccount` |

### 运行时自动识别

OpenClaw 会在运行时注入 `OPENCLAW_ACCOUNT_ID` 环境变量，技能会自动读取对应账户的凭证。

## 验证多账户配置

```bash
# 运行健康检查
./scripts/healthcheck.sh

# 输出示例：
# [PASS] 飞书账户 [coder]: cli_a94ed64eb1f89bc0
# [PASS] 飞书账户 [writer]: cli_a94980d5d9381bda
```

## 手动指定账户

```bash
# 发送语音到 coder 账户
./scripts/feishu-tts.sh output.mp3 ou_xxx coder

# 发送语音到 writer 账户
./scripts/feishu-tts.sh output.mp3 ou_xxx writer
```

## 工作流程

```
用户发送语音消息
    ↓
OpenClaw 识别 agent (通过 bindings)
    ↓
注入 OPENCLAW_ACCOUNT_ID 环境变量
    ↓
技能读取对应账户凭证
    ↓
使用正确的飞书应用发送回复
```
FILE:OPTIMIZATION_0.1.4.md
# Li Feishu Audio 0.1.4 优化总结

## 优化时间
2026-03-22 21:11

## 问题识别

用户发现以下调试信息被发送给用户：
- `/tmp/openclaw/tts-MB1NBC/voice-1774183714190.mp3`
- `📎 /tmp/openclaw/tts-5E4fDV/voice-1774183713165.mp3`
- `（已发送语音回复）`

这些内部调试信息不应该通过用户消息通道发送。

## 优化内容

### 1. 日志系统重构

#### 新增文件
- `scripts/LOGGING.md` - 日志管理文档
- `src/log_config.py` - Python 日志配置模块

#### 日志目录结构
```
/tmp/openclaw/
├── openclaw-YYYY-MM-DD.log      # 主日志
├── feishu-tts-YYYY-MM-DD.log    # 飞书发送日志
├── whisper-YYYY-MM-DD.log       # 语音识别日志
└── cleanup-YYYY-MM-DD.log       # 清理操作日志
```

### 2. 脚本优化

#### tts-voice.sh
**改动**:
- 日志输出到 stderr，不干扰 stdout
- stdout 仅输出文件路径（供调用者使用）
- Python 代码中使用 logging 模块

**之前**:
```bash
print(f"语音生成完成：{OUTPUT}")  # 输出给用户
echo "$OUTPUT"                    # 再次输出
```

**之后**:
```python
_logger.info(f"TTS 合成成功：{OUTPUT}")  # 输出到日志
print(OUTPUT, flush=True)               # 只输出路径
```

#### feishu-tts.sh
**改动**:
- 新增日志函数 `log()`，输出到文件和 stderr
- 成功/失败信息不再通过 stdout 发送给用户
- stdout 仅输出 `OK` 或 `ERROR`

**之前**:
```bash
echo "语音消息已发送（时长：DURATION_MSms）"  # 发送给用户
```

**之后**:
```bash
log "语音消息发送成功（用户：$USER_ID, 时长：DURATION_MSms）"  # 日志
echo "OK"  # 供调用者判断
```

#### fast-whisper-fast.sh
**改动**:
- 日志输出到文件和 stderr
- stdout 仅输出识别文本（无时间戳）
- 错误信息不暴露文件路径

**之前**:
```bash
print("[%.2fs -> %.2fs] %s" % (segment.start, segment.end, segment.text))
```

**之后**:
```python
print(segment.text.strip(), flush=True)  # 只输出文本
_logger.info(f"识别完成：{info.language}")  # 日志
```

#### cleanup-tts.sh
**改动**:
- 新增 `--weekly` 参数，支持每周清理模式
- 日志输出到文件，stdout 仅输出简洁结果
- 自动清理 7 天前的日志文件

**新增功能**:
```bash
# 日常清理（每天凌晨 2 点）
./cleanup-tts.sh 10

# 每周清理（每周日凌晨 3 点）
./cleanup-tts.sh --weekly
```

### 3. Python 模块优化

#### 新增 log_config.py
统一的日志配置模块：
- 自动创建日志目录
- 按模块名称创建日志文件
- 同时输出到控制台和文件
- 支持环境变量配置

#### voice.py 优化建议
后续可将 `_logger` 配置改为使用 `log_config.get_logger(__name__)`

### 4. 文档更新

#### SKILL.md
- 新增"日志管理"章节
- 更新版本信息为 0.1.4
- 添加作者信息

#### _meta.json
- 版本号：0.1.3 → 0.1.4
- 作者：北京老李
- 新增 changelog

#### LOGGING.md
完整的日志管理文档：
- 日志目录配置
- 日志文件说明
- 清理策略
- 查看日志方法
- 配置示例

## 清理策略

### 日常清理（每天凌晨 2 点）
- 保留最近 10 个 TTS 目录
- 最大空间 100MB
- 清理脚本临时文件

### 每周清理（每周日凌晨 3 点）
- 保留最近 5 个 TTS 目录
- 清理 7 天前的日志文件
- 最大空间 50MB

### Cron 配置示例
```bash
# 每天凌晨 2 点清理
0 2 * * * /root/.openclaw/workspace/skills/li-feishu-audio/scripts/cleanup-tts.sh 10

# 每周日凌晨 3 点清理
0 3 * * 0 /root/.openclaw/workspace/skills/li-feishu-audio/scripts/cleanup-tts.sh --weekly
```

## 测试验证

### TTS 测试
```bash
$ ./scripts/tts-voice.sh "测试日志隔离" 2>&1
/tmp/tts-output-1774185496.mp3
```
✅ stdout 仅输出文件路径

### 飞书发送测试
```bash
$ ./scripts/feishu-tts.sh /tmp/test.mp3 test_user 2>&1
[2026-03-22 21:18:20] 错误：发送失败（用户：test_user）
ERROR: {"code":99992351,...}
```
✅ 日志输出到文件和 stderr，stdout 输出 ERROR

### 日志文件验证
```bash
$ ls -lh /tmp/openclaw/*.log
-rw-r--r-- 1 root root  868 3 月 22 21:18 /tmp/openclaw/feishu-tts-2026-03-22.log
-rw-r--r-- 1 root root 4.3M 3 月 22 21:18 /tmp/openclaw/openclaw-2026-03-22.log
```
✅ 日志文件正常创建

## 用户影响

### 之前（有问题）
用户收到消息：
```
语音生成完成：/tmp/openclaw/tts-MB1NBC/voice-1774183714190.mp3
📎 /tmp/openclaw/tts-5E4fDV/voice-1774183713165.mp3
（已发送语音回复）
```

### 之后（已修复）
用户收到消息：
```
<qqvoice>/tmp/openclaw/tts-xxx/voice-xxx.opus</qqvoice>
```
或其他正常的文字回复，不包含调试信息。

## 后续建议

1. **voice.py 更新** - 将 `_logger` 配置改为使用 `log_config.get_logger(__name__)`
2. **日志轮转** - 考虑使用 `logging.handlers.TimedRotatingFileHandler`
3. **日志级别** - 支持通过环境变量动态调整日志级别
4. **监控告警** - 集成 Prometheus 或 Grafana 监控日志

## 总结

本次优化全面解决了调试信息泄露给用户的问题：
- ✅ 所有脚本日志输出到文件
- ✅ stdout 仅输出必要返回值
- ✅ stderr 供调试使用
- ✅ 自动清理策略（日常 + 每周）
- ✅ 完整的日志文档

# Security Fixes for v0.1.6

## 修复的安全问题

### 1. ✅ Shell 注入漏洞 (P0)
**问题**: `scripts/common.sh` 中 `run_with_retry()` 使用 `eval "$cmd"`，存在命令注入风险

**修复**: 
- 改用数组参数 `"$@"` 直接执行命令
- 移除所有 eval 调用
- 添加命令脱敏显示

```bash
# 修复前（危险）
run_with_retry() {
    local cmd="$1"
    eval "$cmd"  # ❌ 命令注入风险
}

# 修复后（安全）
run_with_retry() {
    local max_retries="-3"
    local retry_delay="-2"
    shift 2
    "$@"  # ✅ 直接执行，无注入风险
}
```

### 2. ✅ 供应链攻击 - curl|sh (P0)
**问题**: `install.sh` 和 `install-with-model-choice.sh` 使用 `curl -sSf URL | sh`，存在供应链攻击风险

**修复**:
- 先下载到临时文件
- 验证脚本头（shebang 检查）
- 再执行本地文件
- 失败时回退到 pip 安装

```bash
# 修复前（危险）
curl -sSf https://astral.sh/uv/install.sh | sh  # ❌ 直接执行远程代码

# 修复后（安全）
UV_INSTALL_SCRIPT="/tmp/uv-install-$$.sh"
if curl -sSf https://astral.sh/uv/install.sh -o "$UV_INSTALL_SCRIPT"; then
    if head -1 "$UV_INSTALL_SCRIPT" | grep -qE '^#!(/bin/sh|/bin/bash)'; then
        sh "$UV_INSTALL_SCRIPT"  # ✅ 先验证再执行
    fi
    rm -f "$UV_INSTALL_SCRIPT"
fi
```

### 3. ✅ 元数据不一致 (P0)
**问题**: `_meta.json` 版本号 1.0.0 与实际 0.1.6 不符，未声明必要环境变量

**修复**:
```json
{
    "version": "0.1.6",
    "requiredTools": ["ffmpeg", "jq", "python3"],
    "requiredEnvVars": ["FEISHU_APP_ID", "FEISHU_APP_SECRET"],
    "optionalEnvVars": ["WHISPER_MODEL", "FAST_WHISPER_MODEL_DIR", "LOG_LEVEL", "PRIVACY_MODE"]
}
```

### 4. ✅ 非官方镜像警告 (P1)
**问题**: 使用 `hf-mirror.com` 非官方镜像，无用户提示

**修复**:
- 添加警告提示用户这是非官方镜像
- 提供 `USE_HF_MIRROR` 环境变量让用户选择
- 默认启用（考虑国内访问速度），但明确告知用户

```bash
: "=true"
if [ "$USE_HF_MIRROR" = "true" ]; then
    echo "⚠️  使用非官方镜像 hf-mirror.com（国内访问更快）"
    export HF_ENDPOINT="https://hf-mirror.com"
fi
```

### 5. ✅ openclaw.json 凭证读取风险 (P1)
**问题**: 脚本读取 `~/.openclaw/openclaw.json`，可能访问其他频道凭证

**修复**:
- 优先使用环境变量（推荐方式）
- 添加安全警告提示用户使用环境变量更安全
- 仅读取飞书相关凭证字段，不读取整个文件
- 日志中脱敏处理

```bash
# 优先环境变量
if [ -n "$FEISHU_APP_ID" ] && [ -n "$FEISHU_APP_SECRET" ]; then
    # ✅ 使用环境变量，最安全
fi

# 配置文件回退（带警告）
log_warn "⚠️  从配置文件加载凭证存在安全风险，建议设置环境变量"
APP_ID=$(jq -r '.feishu_app_id // empty' "$config_file")  # 仅读取必要字段
```

## 安全验证

```bash
# 检查 eval 使用情况
grep -rn "eval" scripts/*.sh  # 无结果 ✅

# 检查 curl|sh 使用情况
grep -rn "curl.*|.*sh" scripts/*.sh  # 无结果 ✅

# 检查版本号
cat _meta.json | jq '.version'  # "0.1.6" ✅

# 检查环境变量声明
cat _meta.json | jq '.requiredEnvVars'  # ["FEISHU_APP_ID", "FEISHU_APP_SECRET"] ✅
```

## 剩余风险提示

1. **hf-mirror.com**: 仍默认使用非官方镜像，用户可通过 `USE_HF_MIRROR=false` 切换到官方源
2. **openclaw.json**: 仍支持从配置文件读取凭证作为回退，建议用户始终使用环境变量

## 建议用户配置

```bash
# 推荐：使用环境变量（最安全）
export FEISHU_APP_ID="your-app-id"
export FEISHU_APP_SECRET="your-app-secret"
export WHISPER_MODEL="base"
export LOG_LEVEL="INFO"
export PRIVACY_MODE="standard"

# 可选：使用官方 HuggingFace 源
export USE_HF_MIRROR="false"
```

FILE:SECURITY_WARNING.md
# ⚠️ 安全警告

# 日志管理文档

## 日志配置

### 日志目录
- **默认位置**: `/tmp/openclaw/`
- **可配置**: 通过 `.env` 文件设置 `LOG_DIR` 环境变量

### 日志文件

| 脚本 | 日志文件 | 说明 |
|------|----------|------|
| `tts-voice.sh` | `/tmp/openclaw/openclaw-YYYY-MM-DD.log` | TTS 合成日志 |
| `feishu-tts.sh` | `/tmp/openclaw/feishu-tts-YYYY-MM-DD.log` | 飞书语音发送日志 |
| `cleanup-tts.sh` | `/tmp/openclaw/cleanup-YYYY-MM-DD.log` | 清理操作日志 |
| `fast-whisper-fast.sh` | `/tmp/openclaw/whisper-YYYY-MM-DD.log` | 语音识别日志 |

## 日志级别

- **INFO**: 正常操作流程
- **WARN**: 警告信息（不影响功能）
- **ERROR**: 错误信息（需要关注）

## 清理策略

### 自动清理

1. **日常清理**（每天凌晨 2 点）
   ```bash
   ./scripts/cleanup-tts.sh 10
   ```
   - 保留最近 10 个 TTS 目录
   - 最大空间 100MB

2. **每周清理**（每周日凌晨 3 点）
   ```bash
   ./scripts/cleanup-tts.sh --weekly
   ```
   - 保留最近 5 个 TTS 目录
   - 清理 7 天前的日志文件
   - 最大空间 50MB

### 手动清理

```bash
# 清理所有临时文件
./scripts/cleanup-tts.sh 0

# 清理并查看日志
./scripts/cleanup-tts.sh --weekly
cat /tmp/openclaw/cleanup-$(date +%Y-%m-%d).log
```

## 日志格式

```
[YYYY-MM-DD HH:MM:SS] [LEVEL] 消息内容
```

示例：
```
[2026-03-22 21:14:37] [INFO] TTS 合成成功：/tmp/tts-output-1774185280.mp3
[2026-03-22 21:14:38] [INFO] 语音消息发送成功（用户：xxx, 时长：2000ms）
[2026-03-22 21:15:00] [WARN] psutil 未安装，系统资源监控将使用降级方案
```

## 调试信息隔离

所有调试信息（文件路径、临时目录、内部状态）**不会**通过 stdout 输出给用户，而是：

1. **日志文件**: 写入 `/tmp/openclaw/*.log`
2. **stderr**: 供脚本调用者调试使用
3. **stdout**: 仅输出必要的返回值（如文件路径、OK/ERROR）

## 查看日志

```bash
# 查看今日日志
tail -f /tmp/openclaw/openclaw-$(date +%Y-%m-%d).log

# 查看所有日志文件
ls -lh /tmp/openclaw/*.log

# 搜索错误
grep "ERROR" /tmp/openclaw/*.log
```

## 配置示例

在 `scripts/.env` 中添加：

```bash
# 自定义日志目录
LOG_DIR=/var/log/li-feishu-audio

# 自定义临时目录
TEMP_DIR=/tmp

# 飞书凭证
FEISHU_APP_ID=cli_xxx
FEISHU_APP_SECRET=xxx
```

## 注意事项

1. **不要删除正在使用的日志文件** - 可能导致日志丢失
2. **定期清理** - 避免日志文件占用过多磁盘空间
3. **敏感信息** - 日志中不包含用户隐私数据
4. **日志轮转** - 每日自动创建新日志文件

FILE:scripts/MODEL_CHOICE.md
# 模型选择指南

## 快速开始

### 安装时选择模型

使用增强版安装脚本，支持交互式模型选择：

```bash
cd ~/.openclaw/workspace/skills/li-feishu-audio
./scripts/install-with-model-choice.sh
```

安装时会提示：
```
请选择 faster-whisper 模型大小：
  1) tiny   (约 75MB,  最快，准确率较低)  ← 推荐默认
  2) base   (约 142MB, 快速，准确率中等)
  3) small  (约 466MB, 中等速度，准确率高)
  4) medium (约 1.5GB, 较慢，准确率最高)

请选择模型 [1-4, 默认:1]:
```

### 切换已有模型

编辑 `scripts/.env` 文件：

```bash
vi scripts/.env
```

修改 `WHISPER_MODEL` 配置：

```bash
# 从 tiny 切换到 base
WHISPER_MODEL=base
```

然后重新运行安装脚本（会自动检测新模型并下载）：

```bash
./scripts/install-with-model-choice.sh
```

## 模型对比

| 模型 | 大小 | 速度 | 准确率 | 适用场景 |
|------|------|------|--------|----------|
| **tiny** | 75MB | ⚡⚡⚡ | ⭐⭐ | 清晰语音、快速响应 |
| **base** | 142MB | ⚡⚡ | ⭐⭐⭐ | 日常使用（推荐） |
| **small** | 466MB | ⚡ | ⭐⭐⭐⭐ | 嘈杂环境、多方言 |
| **medium** | 1.5GB | 🐌 | ⭐⭐⭐⭐⭐ | 专业场景、高精度要求 |

## 性能参考

在普通 CPU（Intel i5）上的测试：

| 模型 | 识别速度 | 内存占用 |
|------|----------|----------|
| tiny | ~0.3x 实时 | ~500MB |
| base | ~0.5x 实时 | ~800MB |
| small | ~1.0x 实时 | ~1.5GB |
| medium | ~2.0x 实时 | ~3GB |

*注：0.3x 实时 = 1 分钟音频需 18 秒识别完成*

## 配置说明

### 环境变量

在 `scripts/.env` 中配置：

```bash
# 模型名称（tiny/base/small/medium）
WHISPER_MODEL=tiny

# 模型缓存目录（可选）
FAST_WHISPER_MODEL_DIR=/root/.fast-whisper-models

# 虚拟环境目录（可选）
VENV_DIR=/root/.openclaw/workspace/skills/li-feishu-audio/.venv
```

### 脚本中使用

`fast-whisper-fast.sh` 会自动读取配置：

```bash
# 加载环境变量
source scripts/.env

# 运行识别（自动使用配置的模型）
./scripts/fast-whisper-fast.sh audio.wav
```

## 多模型共存

可以安装多个模型，根据需要切换：

```bash
# 首次安装 tiny 模型
WHISPER_MODEL=tiny ./scripts/install-with-model-choice.sh

# 下载 base 模型（不删除 tiny）
WHISPER_MODEL=base ./scripts/install-with-model-choice.sh

# 切换回 tiny
WHISPER_MODEL=tiny ./scripts/fast-whisper-fast.sh audio.wav
```

模型文件会存储在 `FAST_WHISPER_MODEL_DIR` 目录下，按模型名称分隔。

## 手动下载模型

如果自动下载失败，可以手动下载：

```bash
# 使用 hf-mirror 下载
export HF_ENDPOINT=https://hf-mirror.com

cd /root/.fast-whisper-models

# 下载 base 模型
git lfs install
git clone https://hf-mirror.com/Systran/faster-whisper-base.git
```

## 故障排查

### 模型下载失败

```bash
# 检查网络
curl -I https://hf-mirror.com

# 使用代理
export HTTP_PROXY=http://proxy:port
export HTTPS_PROXY=http://proxy:port

# 重新运行安装
./scripts/install-with-model-choice.sh --force
```

### 识别准确率低

1. 尝试更大的模型（tiny → base → small）
2. 确保音频质量良好（无噪音、音量适中）
3. 检查音频格式（推荐 16kHz, 16bit, 单声道）

### 内存不足

```bash
# 检查内存
free -h

# 使用更小的模型
WHISPER_MODEL=tiny
```

## 最佳实践

1. **首次安装**：使用 `tiny` 模型测试功能
2. **日常使用**：升级到 `base` 模型（平衡速度和准确率）
3. **专业场景**：考虑 `small` 或 `medium`（需要更强硬件）
4. **定期清理**：运行 `./scripts/cleanup-tts.sh --weekly` 清理临时文件

## 🛡️ 安全建议

### 立即实施（高优先级）

#### 1. 限制网络访问
**修改 docker-compose.yml：**
```yaml
services:
  kanban:
    ports:
      - "127.0.0.1:9999:5000"  # 仅本地访问
```

#### 2. 添加反向代理
**使用 Nginx：**
```nginx
server {
    listen 443 ssl;
    server_name kanban.local;
    
    ssl_certificate /path/to/cert.pem;
    ssl_certificate_key /path/to/key.pem;
    
    location / {
        proxy_pass http://127.0.0.1:9999;
    }
}
```

#### 3. 添加基础认证
**Nginx 认证：**
```nginx
auth_basic "Restricted Access";
auth_basic_user_file /etc/nginx/.htpasswd;
```

### 短期实施（中优先级）

#### 4. 非 root 容器用户
**修改 Dockerfile：**
```dockerfile
# 创建非 root 用户
RUN useradd -m -u 1000 kanban
USER kanban
```

#### 5. 添加资源限制
**修改 docker-compose.yml：**
```yaml
services:
  kanban:
    deploy:
      resources:
        limits:
          cpus: '1.0'
          memory: 512M
```

#### 6. 数据加密
**加密数据库文件：**
```bash
# 使用 encfs 或类似工具
encfs ~/.kanban-data ~/.kanban-data-encrypted
```

### 长期实施（低优先级）

#### 7. 添加用户认证
**开发计划：**
- 用户登录系统
- 密码哈希存储（bcrypt）
- Session/JWT 认证
- 权限控制

#### 8. 安全扫描
**定期扫描：**
```bash
# 扫描 Docker 镜像
docker scan mvp-kanban:latest

# 扫描代码
bandit -r src/
```

#### 9. 审计日志
**添加日志记录：**
```python
import logging
logging.info(f"User action: {action} by {user}")
```

FILE:SECURITY_AND_PRIVACY.md
# 数据安全与隐私保护声明

## ⚠️ 重要提示

**Li_python_sec_check** 是一个 Python 安全规范检查工具，包含本地检查和可选的 LLM 智能分析功能。

---

## 🔒 数据安全说明

### 默认行为（安全）

✅ **所有核心检查都在本地执行**，不会发送任何数据到外部：

1. 项目结构检查
2. Dockerfile 规范检查
3. requirements.txt 检查
4. Python 版本检查
5. 不安全加密算法检测
6. SQL 注入风险检测
7. 命令注入风险检测
8. 敏感信息硬编码检测
9. 调试模式检测
10. flake8 代码质量检查
11. bandit 安全扫描
12. pip-audit 依赖漏洞扫描
13. **隐私信息泄露检查**
14. **数据安全检查**

### LLM 功能（可选，默认禁用）

⚠️ **仅在显式启用 `--llm` 参数时**，才会调用外部 API：

```bash
# ⚠️ 此命令会发送代码到外部 API
python scripts/python_sec_check.py /path/to/project --llm
```

**发送的数据包括**:
- 代码片段（用于分析）
- 扫描结果（用于生成修复建议）

**不发送的数据**:
- 完整源代码文件
- 项目结构信息
- 用户凭证

---

## 🛡️ 安全使用建议

### 1. 敏感代码项目

```bash
# ✅ 推荐：仅使用本地检查
python scripts/python_sec_check.py /path/to/sensitive-project

# ❌ 避免：不要启用 LLM
# python scripts/python_sec_check.py /path/to/sensitive-project --llm
```

### 2. 企业环境

```bash
# ✅ 推荐：使用私有 API 端点
export LLM_API_BASE=https://internal-llm.your-company.com/v1
export LLM_API_KEY=your-internal-key
python scripts/python_sec_check.py /path/to/project --llm
```

### 3. 开源项目

```bash
# ✅ 可以使用公共 LLM API
python scripts/python_sec_check.py /path/to/open-source-project --llm
```

---

## 📋 环境变量配置

| 变量 | 说明 | 默认值 | 建议 |
|------|------|--------|------|
| `LLM_API_KEY` | LLM API 密钥 | 无 | 仅在需要 LLM 时设置 |
| `LLM_API_BASE` | LLM API 端点 | https://dashscope.aliyuncs.com | 企业用户应设置为私有端点 |

---

## 🔍 网络行为说明

### 本地检查（默认）

- ❌ **不**发起任何网络请求
- ❌ **不**发送任何数据到外部
- ✅ 所有分析在本地完成

### LLM 分析（可选）

- ✅ 仅在 `--llm` 参数启用时
- ✅ 发送代码片段到配置的 API 端点
- ✅ 接收分析结果和建议

---

---

## 🎯 最佳实践

### 1. 默认禁用 LLM

```bash
# ✅ 推荐：默认不使用 LLM
python scripts/python_sec_check.py /path/to/project
```

### 2. 审查 LLM 代码

在使用 LLM 功能前，建议审查 `scripts/llm_analyzer.py`：

```bash
# 查看 LLM 模块代码
cat scripts/llm_analyzer.py | head -50
```

### 3. 使用隔离环境

```bash
# 在容器或 VM 中运行
docker run --rm -v $(pwd):/app python:3.9 \
  python scripts/python_sec_check.py /app
```

### 4. 定期检查更新

```bash
# 更新技能到最新版本
clawhub update Li_python_sec_check
```

# ClawHub 安全审查回应

## 审查意见总结

审查者指出了以下关键问题：

### ✅ 已确认安全的方面

1. ✅ **目的和能力匹配** - 技能确实实现了本地 Python 安全扫描器
2. ✅ **安装机制** - 无远程下载，使用标准 pip/venv
3. ✅ **持久性和权限** - 无特殊权限要求

### ⚠️ 需要改进的方面

1. ⚠️ **LLM 网络行为警告不明确** - 没有清晰说明代码会发送到外部 API
2. ⚠️ **凭证声明缺失** - 未在元数据中声明可选的 LLM API 凭证
3. ⚠️ **数据外泄风险** - 启用 LLM 后可能发送敏感代码

### 1. 明确的数据安全声明

**新增文件**: `SECURITY_AND_PRIVACY.md`

包含：
- ✅ 默认行为说明（本地执行）
- ✅ LLM 功能警告（可选，默认禁用）
- ✅ 数据流向图
- ✅ 安全使用建议
- ✅ 企业合规指南

### 2. 更新 SKILL.md

添加明确的警告：

```markdown
## ⚠️ 重要安全提示

**LLM 功能默认禁用**，需要显式启用：

- ⚠️ **默认行为**: 所有检查都在**本地执行**，不会发送任何数据到外部
- ⚠️ **LLM 功能**: 仅在显式使用 `--llm` 参数时才会调用外部 API
- ⚠️ **数据外传**: 启用 LLM 后，代码片段和扫描结果会发送到外部 API
- ✅ **隐私保护**: 建议扫描敏感代码时**不要启用** `--llm` 参数
- ✅ **企业使用**: 可设置 `LLM_API_BASE` 为内部私有 API 端点
```

### 3. 更新 _meta.json

添加安全元数据：

```json
{
  "version": "0.0.2",
  "security": {
    "network_access": "optional",
    "network_description": "LLM 功能默认禁用，仅在显式使用 --llm 参数时调用外部 API",
    "data_handling": "所有核心检查（14 项）在本地执行。启用 --llm 后代码片段会发送到配置的 API 端点",
    "credentials": {
      "LLM_API_KEY": "optional",
      "LLM_API_BASE": "optional"
    },
    "privacy_notice": "扫描敏感代码时建议禁用 --llm 参数，或使用私有 API 端点",
    "default_behavior": "local-only",
    "llm_warning": "显式启用 --llm 时会在控制台显示警告"
  }
}
```

### 4. 增强 LLM 模块警告

**更新**: `scripts/llm_analyzer.py`

```python
class LLMAnalyzer:
    """LLM 智能分析器
    
    ⚠️ 安全提示:
    - 此模块会将代码片段发送到外部 API 进行分析
    - 默认 API 端点：https://dashscope.aliyuncs.com/compatible-mode/v1
    - 敏感代码建议使用私有 API 端点或禁用 LLM 功能
    - 可通过 LLM_API_BASE 环境变量配置私有端点
    """
    
    def __init__(self, api_key: Optional[str] = None, model: str = "qwen3.5-plus"):
        self.api_key = api_key or os.environ.get('LLM_API_KEY')
        self.model = model
        self.api_base = os.environ.get('LLM_API_BASE', 'https://dashscope.aliyuncs.com/compatible-mode/v1')
        
        # 安全警告
        if self.api_key:
            print(f"⚠️  LLM 分析已启用 - 代码数据将发送到：{self.api_base}")
            print(f"⚠️  敏感代码建议使用私有 API 端点或禁用 LLM 功能")
```

### 5. 更新 package.json

添加安全元数据：

```json
{
  "version": "0.0.2",
  "skill": {
    "security": {
      "network_access": "optional",
      "default_behavior": "local-only",
      "llm_warning": true
    }
  }
}
```

## 使用示例对比

### v0.0.1 (之前)

```bash
# 用户可能不知道会发送数据
python scripts/python_sec_check.py /path/to/project --llm
```

### v0.0.2 (现在)

```bash
# 1. 默认本地执行（安全）
python scripts/python_sec_check.py /path/to/project

# 2. 启用 LLM 时会显示警告
python scripts/python_sec_check.py /path/to/project --llm
# ⚠️  LLM 分析已启用 - 代码数据将发送到：https://dashscope.aliyuncs.com/compatible-mode/v1
# ⚠️  敏感代码建议使用私有 API 端点或禁用 LLM 功能

# 3. 企业可使用私有端点
export LLM_API_BASE=https://internal-llm.company.com/v1
python scripts/python_sec_check.py /path/to/project --llm
```

# CodeQL + LLM 融合安全扫描 Skill

## 🎯 核心功能

本 Skill 实现 CodeQL 扫描与 LLM 智能分析的完整自动化流程：

1. **自动检测** - 检查 CodeQL 是否安装及版本
2. **安全扫描** - 扫描指定目录或靶机项目
3. **报告生成** - 生成 SARIF 格式和 Markdown 格式报告
4. **LLM 分析** - 智能分析扫描结果，识别误报，给出优先级
5. **验证清单** - 生成可执行的漏洞验证 Checklist

---

## 📦 前置要求

### 必需
- **CodeQL CLI** (v2.10.0+)
- **Python 3.11+** (用于创建数据库)
- **uv** 或 **pip** (Python 包管理)

### 可选
- **Node.js** (用于某些语言的分析)
- **Java JDK** (用于 Java 项目分析)

---

## 🚀 快速开始

### 1. 检查环境

```bash
# 检查 CodeQL 是否安装
codeql --version

# 如果未安装，下载并解压
wget https://github.com/github/codeql-cli-binaries/releases/latest/download/codeql-linux64.zip
unzip codeql-linux64.zip -d /opt/codeql
ln -s /opt/codeql/codeql/codeql /usr/local/bin/codeql
```

### 2. 使用 Skill

在对话中直接请求：

```
扫描 /path/to/project 的安全漏洞
```

或指定靶机目录：

```
扫描 /root/devsecops-python-web 靶机，生成验证清单
```

---

## 📋 命令参考

### 基础扫描

```bash
# 扫描当前目录
codeql database create codeql-db --language=python --source-root=.
codeql database analyze codeql-db python-security-extended.qls \
  --format=sarif-latest --output=results.sarif
```

### 通过 Skill 调用

在 OpenClaw 会话中：

```
/codeql_scan /path/to/project
```

或直接描述需求：

```
帮我扫描这个项目，用 CodeQL 分析安全问题，然后生成报告
```

---

## 📊 工作流程

### Step 1: 环境检测

```bash
# 检查 CodeQL
which codeql && codeql --version

# 检查支持的語言
codeql resolve languages
```

### Step 2: 创建数据库

```bash
# Python 项目
codeql database create codeql-db \
  --language=python \
  --source-root=/path/to/project \
  --overwrite
```

### Step 3: 运行分析

```bash
# 下载查询包
codeql pack download codeql/python-queries

# 运行分析
codeql database analyze codeql-db \
  /root/.codeql/packages/codeql/python-queries/*/codeql-suites/python-security-extended.qls \
  --format=sarif-latest \
  --output=codeql-results.sarif
```

### Step 4: LLM 分析

将 SARIF 结果发送给 LLM：

```python
import json

with open('codeql-results.sarif') as f:
    data = json.load(f)

# 提取关键信息
results = data['runs'][0]['results']
for r in results:
    print(f"规则：{r['ruleId']}")
    print(f"描述：{r['message']['text']}")
    print(f"位置：{r['locations'][0]['physicalLocation']['artifactLocation']['path']}")
```

LLM 分析内容：
- 漏洞严重程度排序
- 误报识别
- 修复建议
- 利用难度评估

### Step 5: 生成报告

生成以下文件：

1. **CODEQL_SECURITY_REPORT.md** - 完整扫描报告
2. **漏洞验证_Checklist.md** - 可执行的验证清单
3. **codeql-results.sarif** - 原始结果（可上传 GitHub Security）

---

## 🔧 配置选项

### 扫描语言

```bash
# Python
--language=python

# JavaScript
--language=javascript

# Java
--language=java

# Go
--language=go

# 多语言
--language=python,javascript
```

### 查询套件

```bash
# 安全扩展（推荐）
python-security-extended.qls

# 代码质量
python-code-quality.qls

# 安全与质量
python-security-and-quality.qls

# 代码扫描（默认）
python-code-scanning.qls
```

### 输出格式

```bash
# SARIF（推荐）
--format=sarif-latest

# CSV

```

---

## 🐛 常见问题

### Q: CodeQL 数据库创建失败？

**A**: 确保项目可以正常构建：
```bash
# Python 项目
python -m pip install -r requirements.txt

# 然后创建数据库
codeql database create db --language=python
```

### Q: 扫描结果太多？

**A**: 使用过滤：
```bash
# 只看严重和高危
codeql database analyze db python-security-extended.qls \
  --rerun --checkout=latest \
  --sarif-category=severity \
  --output=results.sarif
```

### Q: 如何减少误报？

**A**: 
1. 使用 `python-security-extended.qls` 而非 `python-code-scanning.qls`
2. 让 LLM 分析识别误报
3. 手动验证关键漏洞

## 🔧 集成方案

### 方案 1: 扫描后自动分析（推荐）✨

**流程**:
```
CodeQL 扫描 → 生成报告 → OpenClaw LLM 分析 → 增强报告
```

**实现**:
```python
# 在 scanner.py 中添加
async def analyze_with_llm(sarif_file: str, report_file: str):
    """使用 OpenClaw LLM 分析报告"""
    
    from openclaw_sdk import OpenClawClient
    from pydantic import BaseModel
    
    # 定义输出模型
    class SecurityAnalysis(BaseModel):
        summary: str
        critical_count: int
        high_count: int
        medium_count: int
        false_positives: list[str]
        top_5_priority: list[str]
        remediation_plan: list[str]
    
    # 连接 OpenClaw
    async with OpenClawClient.connect() as client:
        agent = client.get_agent("security-analyst")
        
        # 读取 SARIF 报告
        with open(sarif_file) as f:
            sarif_content = f.read()
        
        # 执行分析
        analysis: SecurityAnalysis = await agent.execute_structured(
            f"""分析这个 CodeQL 安全扫描报告：
            
            {sarif_content[:50000]}  # 限制长度
            
            请提供：
            1. 漏洞摘要
            2. 按严重程度统计
            3. 可能的误报
            4. 优先级前 5 的漏洞
            5. 修复建议""",
            output_model=SecurityAnalysis
        )
        
        # 生成增强报告
        generate_enhanced_report(analysis, report_file)
```

### 方案 2: 独立分析脚本

**文件**: `analyze_with_llm.py`

```python
#!/usr/bin/env python3

    remediation_steps: list[str]
    exploit_difficulty: str


async def analyze_sarif(sarif_file: str, output_file: str):
    """分析 SARIF 文件"""
    
    # 读取报告
    with open(sarif_file) as f:
        sarif_data = json.load(f)

"""
    
    # 使用 OpenClaw 分析
    async with OpenClawClient.connect() as client:
        agent = client.get_agent("security-analyst")
        
        analysis: VulnerabilityAnalysis = await agent.execute_structured(
            analysis_prompt,
            output_model=VulnerabilityAnalysis
        )
    
    # 保存分析结果
    with open(output_file, 'w', encoding='utf-8') as f:
        f.write("# CodeQL 漏洞分析报告（LLM 增强版）\n\n")
        f.write(f"## 摘要\n\n{analysis.summary}\n\n")

        for i, step in enumerate(analysis.remediation_steps, 1):
            f.write(f"{i}. {step}\n")
    
    print(f"✅ 分析完成：{output_file}")


async def main():
    import argparse
    
    parser = argparse.ArgumentParser(description='LLM 分析 CodeQL 结果')
    parser.add_argument('sarif_file', help='SARIF 文件路径')
    parser.add_argument('-o', '--output', default='llm-analysis.md', help='输出文件')
    
    args = parser.parse_args()
    
    await analyze_sarif(args.sarif_file, args.output)


if __name__ == '__main__':
    asyncio.run(main())
```

### 方案 3: Jenkins Pipeline 集成

**修改 Jenkinsfile**:

```groovy
stage('LLM 分析 / LLM Analysis') {
    steps {
        script {
            echo "🤖 使用 OpenClaw LLM 分析..."
            
            sh """
                cd SCANNER_DIR
                export OPENCLAW_GATEWAY_WS_URL=ws://localhost:18789/gateway
                python3 analyze_with_llm.py \\
                    params.OUTPUT_DIR/codeql-results.sarif \\
                    -o params.OUTPUT_DIR/llm-analysis.md
            """
        }
    }
}

stage('发布 LLM 报告 / Publish LLM Report') {
    steps {
        publishHTML([
            allowMissing: false,
            alwaysLinkToLastBuild: true,
            keepAll: true,
            reportDir: params.OUTPUT_DIR,
            reportFiles: 'llm-analysis.md',
            reportName: 'LLM Security Analysis'
        ])
    }
}
```

    # 调用 LLM 分析结果
```

### 3. 自定义查询

支持加载自定义查询：
```bash
./run.sh /path/to/project \
  --custom-queries /path/to/my-queries.qls
```

### 4. 历史对比

对比多次扫描结果：
```bash
./run.sh /path/to/project --compare ./previous-scan
```

# Jenkins Pipeline 手动配置指南
# Jenkins Pipeline Manual Configuration Guide

## ⚠️ 为什么需要手动配置？

由于 Jenkins CSRF 保护，自动创建任务需要正确的 crumb。如果自动创建失败，请按以下步骤手动配置。

---

## 📋 方法 1: 使用 Jenkins Web 界面（推荐）

### 步骤 1: 创建新任务

1. **访问 Jenkins**
   ```
   http://localhost:8080
   用户名：devops
   密码：devsecops
   ```

2. **点击 "新建任务" (New Item)**

3. **输入任务名称**
   ```
   名称：codeql-security-scan
   类型：Pipeline
   ```

4. **点击 "确定" (OK)**

### 步骤 2: 配置 Pipeline

1. **滚动到 "Pipeline" 部分**

2. **选择 "Pipeline script"**

3. **复制以下内容到脚本框**:

```groovy
pipeline {
    agent any
    
    parameters {
        string(name: 'SCAN_TARGET', defaultValue: '/root/devsecops-python-web', description: '要扫描的项目目录')
        string(name: 'CODEQL_LANGUAGE', defaultValue: 'python', description: '编程语言')
        string(name: 'CODEQL_SUITE', defaultValue: 'python-security-extended.qls', description: '查询套件')
        string(name: 'OUTPUT_DIR', defaultValue: './codeql-scan-output', description: '输出目录')
        booleanParam(name: 'SECURITY_CHECK', defaultValue: true, description: '扫描前安全检查')
    }
    
    environment {
        CODEQL_PATH = '/opt/codeql/codeql'
        SCANNER_DIR = "env.HOME/.openclaw/workspace/skills/codeql-llm-scanner"
    }
    
    stages {
        stage('准备环境') {
            steps {
                script {
                    echo "🔧 准备扫描环境..."
                    echo "📂 扫描目标：params.SCAN_TARGET"
                    env.PATH = "CODEQL_PATH:env.PATH"
                    sh 'codeql --version'
                }
            }
        }
        
        stage('安全检查') {
            when { expression { return params.SECURITY_CHECK } }
            steps {
                script {
                    echo "🔍 运行安全检查..."
                    sh "cd SCANNER_DIR && python3 security_check.py params.SCAN_TARGET || true"
                }
            }
        }
        
        stage('CodeQL 扫描') {
            steps {
                script {
                    echo "🔍 运行 CodeQL 扫描..."
                    sh """
                        cd SCANNER_DIR
                        export PATH=CODEQL_PATH:\$PATH
                        python3 scanner.py \\
                            params.SCAN_TARGET \\
                            --output params.OUTPUT_DIR \\
                            --language params.CODEQL_LANGUAGE \\
                            --suite params.CODEQL_SUITE
                    """
                }
            }
        }
        
        stage('生成报告') {
            steps {
                script {
                    archiveArtifacts artifacts: "params.OUTPUT_DIR/*.md,params.OUTPUT_DIR/*.sarif", 
                                     fingerprint: true, allowEmptyArchive: true
                }
            }
        }
        
        stage('发布报告') {
            steps {
                publishHTML([
                    allowMissing: false,
                    alwaysLinkToLastBuild: true,
                    keepAll: true,
                    reportDir: params.OUTPUT_DIR,
                    reportFiles: 'CODEQL_SECURITY_REPORT.md',
                    reportName: 'CodeQL Security Report'
                ])
            }
        }
    }
    
    post {
        success {
            echo "✅ 扫描成功完成！"
        }
        failure {
            echo "❌ 扫描失败"
        }
    }
}
```

4. **点击 "保存" (Save)**

### 步骤 3: 运行 Pipeline

1. **点击 "立即构建" (Build Now)**

2. **输入参数**:
   - `SCAN_TARGET`: 要扫描的目录（如：`/root/devsecops-python-web`）
   - `CODEQL_LANGUAGE`: 编程语言（如：`python`）
   - `CODEQL_SUITE`: 查询套件

3. **点击 "构建" (Build)**

---

## 📋 方法 2: 使用 Jenkinsfile

### 步骤 1: 创建任务

1. **访问 Jenkins**
   ```
   http://localhost:8080
   用户名：devops
   密码：devsecops
   ```

2. **新建任务**
   ```
   名称：codeql-security-scan
   类型：Pipeline
   ```

### 步骤 2: 配置 Pipeline script from SCM

1. **在 Pipeline 部分，选择 "Pipeline script from SCM"**

2. **SCM 选择 "Git"**

3. **配置 Git 仓库**（如果有）
   ```
   Repository URL: http://localhost:3000/devops/devsecops-python-web.git
   Credentials: devops/devsecops
   ```

4. **脚本路径**: `Jenkinsfile`

5. **保存**

---

## 📋 方法 3: 使用命令行（需要禁用 CSRF）

### 临时禁用 CSRF（仅测试环境）

```bash
# 1. 访问 Jenkins 脚本命令行
# http://localhost:8080/script

# 2. 执行以下 Groovy 脚本
Jenkins.instance.getDescriptor("hudson.security.csrf.DefaultCrumbIssuer").setUseStandardCrumb(false)
```

### 然后运行创建脚本

```bash
cd ~/.openclaw/workspace/skills/codeql-llm-scanner
python3 create_jenkins_job.py
```

---

## 🔧 配置说明

### .env 中的 Jenkins 配置

```ini
# Jenkins 配置
JENKINS_URL=http://localhost:8080
JENKINS_USER=devops
JENKINS_TOKEN=devsecops
JENKINS_JOB_NAME=codeql-security-scan
JENKINS_UPLOAD_SARIF=true

# 默认扫描目录（可以在 Jenkins 中覆盖）
JENKINS_SCAN_TARGET=/root/devsecops-python-web

# 是否自动创建 Jenkins Pipeline
JENKINS_AUTO_CREATE_PIPELINE=true
```

### Pipeline 参数说明

| 参数 | 说明 | 默认值 |
|------|------|--------|
| `SCAN_TARGET` | 要扫描的目录 | `/root/devsecops-python-web` |
| `CODEQL_LANGUAGE` | 编程语言 | `python` |
| `CODEQL_SUITE` | 查询套件 | `python-security-extended.qls` |
| `OUTPUT_DIR` | 输出目录 | `./codeql-scan-output` |
| `SECURITY_CHECK` | 安全检查 | `true` |

---

## ✅ 验证配置

### 1. 检查任务是否创建

```bash
curl -u devops:devsecops http://localhost:8080/job/codeql-security-scan/api/json
```

### 2. 触发构建

```bash
curl -u devops:devsecops \
  -X POST http://localhost:8080/job/codeql-security-scan/build \
  --data-urlencode json='{"parameter": [{"name":"SCAN_TARGET","value":"/root/devsecops-python-web"}]}'
```

### 3. 查看构建状态

```bash
curl -u devops:devsecops \
  http://localhost:8080/job/codeql-security-scan/lastBuild/api/json
```

---

## 🐛 故障排查

### 问题 1: 403 Forbidden

**原因**: CSRF crumb 问题

**解决**:
1. 使用方法 1（Web 界面）手动创建
2. 或临时禁用 CSRF（测试环境）

### 问题 2: 找不到任务

**解决**:
```bash
# 列出所有任务
curl -u devops:devsecops http://localhost:8080/api/json | python3 -m json.tool

FILE:Jenkins_Pipeline_修复报告.md
# Jenkins Pipeline 修复报告

**修复时间**: 2026-03-19 07:32  
**问题**: 数据库创建失败 - 输出目录不存在

---

## ❌ 原始错误

```
[Pipeline] sh
+ codeql database create ./codeql-scan-output/codeql-db ...
A fatal error occurred: Cannot create database at 
/root/.openclaw/workspace/skills/codeql-llm-scanner/codeql-scan-output/codeql-db 
because /root/.openclaw/workspace/skills/codeql-llm-scanner/codeql-scan-output does not exist..
```

**原因**: `OUTPUT_DIR` 目录不存在，CodeQL 无法创建数据库

---

## ✅ 修复方案

### 修改 Jenkinsfile

在创建数据库之前，先创建输出目录：

```groovy
stage('CodeQL 数据库创建 / Create Database') {
    steps {
        script {
            echo "📦 创建 CodeQL 数据库..."
            
            // 确保输出目录存在
            sh """
                mkdir -p params.OUTPUT_DIR
            """
            
            sh """
                cd SCANNER_DIR
                export PATH=CODEQL_PATH:\$PATH
                codeql database create params.OUTPUT_DIR/codeql-db \
                    --language=params.CODEQL_LANGUAGE \
                    --source-root=params.SCAN_TARGET \
                    --overwrite
            """
        }
    }
}
```

---

## 🔧 修复内容

### 添加的步骤

```groovy
// 确保输出目录存在
sh """
    mkdir -p params.OUTPUT_DIR
"""
```

**说明**:
- `mkdir -p`: 创建目录，如果已存在则不报错
- `params.OUTPUT_DIR`: 使用参数中的输出目录（默认 `./codeql-scan-output`）

---

## 📋 完整的修复后 Pipeline

### 关键修改

| Stage | 修改内容 |
|-------|----------|
| 准备环境 | ✅ 无修改 |
| 安全检查 | ✅ 无修改 |
| **数据库创建** | ✅ **添加目录创建** |
| 安全扫描 | ✅ 无修改 |
| 生成报告 | ✅ 无修改 |
| 发布报告 | ✅ 无修改 |

---

## 🧪 测试步骤

### 1. 更新 Jenkins Pipeline

```bash
# 方法 1: 在 Jenkins 界面更新
1. 访问：http://localhost:8080/job/codeql-security-scan/configure
2. 滚动到 Pipeline 部分
3. 更新脚本（已修复的版本）
4. 保存

# 方法 2: 重新创建（如果需要）
python3 create_jenkins_pipeline.py
```

### 2. 运行测试

```
1. 访问：http://localhost:8080/job/codeql-security-scan/
2. 点击 "立即构建"
3. 使用默认参数
4. 点击 "构建"
5. 查看控制台输出
```

### 预期结果

```
✅ 准备环境
✅ 安全检查（发现 42 个文件）
✅ 创建 CodeQL 数据库（成功）
✅ 运行安全扫描
✅ 生成报告
✅ 发布报告
✅ 扫描成功
```

---

## 📊 安全检查结果

安全检查发现了 42 个文件包含敏感信息，这些都是**预期的**：

### 靶机文件（正常）

```
✅ scripts/create_jenkins_pipeline.py - password @ line 145
✅ vulnerable_apps/a02_crypto/vulnerable_app.py - password @ line 170
✅ vulnerable_apps/a10_exceptional_conditions/vulnerable_app.py - password @ line 36
```

### 依赖包中的示例代码（正常）

```
✅ .venv/lib/python3.11/site-packages/pydantic/types.py - password='password1'
✅ .venv/lib/python3.11/site-packages/sqlalchemy/... - password="tiger"
✅ 等等...
```

**这些都是测试数据或示例代码，不是真实泄露**

---

## 🔧 可选：排除依赖目录

如果不想检查依赖包，可以更新 `.env`：

```ini
EXCLUDE_DIRS=.git,credentials,.env,node_modules,.venv,venv,mlops/.venv
```

或者在 Jenkinsfile 中修改安全检查：

```groovy
stage('安全检查 / Security Check') {
    when {
        expression { return params.SECURITY_CHECK }
    }
    steps {
        script {
            echo "🔍 运行安全检查（排除依赖）..."
            
            // 只检查源代码目录
            sh """
                cd SCANNER_DIR
                python3 security_check.py params.SCAN_TARGET/src || true
                python3 security_check.py params.SCAN_TARGET/scripts || true
                python3 security_check.py params.SCAN_TARGET/vulnerable_apps || true
            """
        }
    }
}
```

**最简单的解决方案**: 通过 Jenkins Web 界面手动更新（2 分钟）

---

## 📋 手动更新步骤（推荐）

### 步骤 1: 访问配置页面

打开浏览器，访问：
```
http://192.168.4.53:8080/job/codeql-security-scan/configure
```

### 步骤 2: 滚动到 Pipeline 部分

向下滚动，找到 **"Pipeline"** 部分

### 步骤 3: 确认脚本已更新

检查脚本中是否包含以下内容：

**搜索关键字**: `mkdir -p`

应该能找到：
```groovy
stage('CodeQL 数据库创建 / Create Database') {
    steps {
        script {
            echo "📦 创建 CodeQL 数据库..."

## 🔒 隐私保护声明 / Privacy Protection Statement

### 中文

**本工具严格保护用户隐私，不会收集、存储或传输任何个人敏感信息。**

#### 数据收集原则

1. **零数据收集** - 本工具不收集任何用户数据
2. **本地处理** - 所有扫描在本地完成，数据不出境
3. **无远程传输** - 扫描结果不会发送到任何远程服务器
4. **用户控制** - 所有输出文件由用户完全控制

#### 扫描数据安全

- ✅ 源代码：仅在本地分析，不上传
- ✅ 扫描结果：存储在用户指定目录
- ✅ 报告文件：生成在本地，不共享
- ✅ LLM 分析：用户可选择是否发送

#### 敏感信息处理

如果扫描发现敏感信息（如密码、密钥等）：

1. **不会自动发送** - 需要用户明确授权
2. **脱敏处理** - 建议用户手动脱敏
3. **本地存储** - 敏感信息保留在本地
4. **用户删除** - 用户可随时删除所有输出

---

### English

**This tool strictly protects user privacy and does not collect, store, or transmit any personal sensitive information.**

#### Data Collection Principles

1. **Zero Data Collection** - This tool does not collect any user data
2. **Local Processing** - All scans are completed locally, data does not leave your environment
3. **No Remote Transmission** - Scan results are not sent to any remote servers
4. **User Control** - All output files are fully controlled by the user

#### Scan Data Security

- ✅ Source code: Only analyzed locally, not uploaded
- ✅ Scan results: Stored in user-specified directory
- ✅ Report files: Generated locally, not shared
- ✅ LLM analysis: User can choose whether to send

#### Sensitive Information Handling

If sensitive information is discovered during scanning (such as passwords, keys, etc.):

1. **No Automatic Sending** - Requires explicit user authorization
2. **Desensitization** - Users are advised to manually desensitize
3. **Local Storage** - Sensitive information remains local
4. **User Deletion** - Users can delete all outputs at any time

    # 'input' function used in Python 2
    In Python 2, a call to the `input()` function, `input(prompt)` is equivalent to `eval(raw_input(prompt))`. Evaluating user input without any checking can be a serious security flaw.


    ## Recommendation
    Get user input with `raw_input(prompt)` and then validate that input before evaluating. If the expected input is a number or string, then `ast.literal_eval()` can always be used safely.

    # Binding a socket to all network interfaces
    Sockets can be used to communicate with other machines on a network. You can use the (IP address, port) pair to define the access restrictions for the socket you create. When using the built-in Python `socket` module (for instance, when building a message sender service or an FTP server data transmitter), one has to bind the port to some interface. When you bind the port to all interfaces using `0.0.0.0` as the IP address, you essentially allow it to accept connections from any IPv4 address provided that it can get to the socket via routing. Binding to all interfaces is therefore associated with security risks.


    ## Recommendation
    Bind your service incoming traffic only to a dedicated interface. If you need to bind more than one interface using the built-in `socket` module, create multiple sockets (instead of binding to one socket to all interfaces).


    ## Example
    In this example, two sockets are insecure because they are bound to all interfaces; one through the `0.0.0.0` notation and another one through an empty string `''`.


    ```python
    import socket

    # binds to all interfaces, insecure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('0.0.0.0', 31137))

    # binds to all interfaces, insecure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('', 4040))

    # binds only to a dedicated interface, secure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('84.68.10.12', 8080))

    ```

    # Construction of a cookie using user-supplied input
    Constructing cookies from user input can allow an attacker to control a user's cookie. This may lead to a session fixation attack. Additionally, client code may not expect a cookie to contain attacker-controlled data, and fail to sanitize it for common vulnerabilities such as Cross Site Scripting (XSS). An attacker manipulating the raw cookie header may additionally be able to set cookie attributes such as `HttpOnly` to insecure values.


    ## Recommendation
    Do not use raw user input to construct cookies.


    ## Example
    In the following cases, a cookie is constructed for a Flask response using user input. The first uses `set_cookie`, and the second sets a cookie's raw value through the `set-cookie` header.


    ```python
    from flask import request, make_response


    @app.route("/1")
    def set_cookie():
        resp = make_response()
        resp.set_cookie(request.args["name"], # BAD: User input is used to set the cookie's name and value
                        value=request.args["name"])
        return resp


    @app.route("/2")
    def set_cookie_header():
        resp = make_response()
        resp.headers['Set-Cookie'] = f"{request.args['name']}={request.args['name']};" # BAD: User input is used to set the raw cookie header.
        return resp

    ```

    # Incomplete regular expression for hostnames
    Sanitizing untrusted URLs is a common technique for preventing attacks such as request forgeries and malicious redirections. Often, this is done by checking that the host of a URL is in a set of allowed hosts.

    If a regular expression implements such a check, it is easy to accidentally make the check too permissive by not escaping the `.` meta-characters appropriately. Even if the check is not used in a security-critical context, the incomplete check may still cause undesirable behaviors when it accidentally succeeds.


    ## Recommendation
    Escape all meta-characters appropriately when constructing regular expressions for security checks, and pay special attention to the `.` meta-character.


    ## Example
    The following example code checks that a URL redirection will reach the `example.com` domain, or one of its subdomains.


    ```python
    from flask import Flask, request, redirect
    import re

    app = Flask(__name__)

    UNSAFE_REGEX = re.compile("(www|beta).example.com/")
    SAFE_REGEX = re.compile(r"(www|beta)\.example\.com/")

    @app.route('/some/path/bad')
    def unsafe(request):
        target = request.args.get('target', '')
        if UNSAFE_REGEX.match(target):
            return redirect(target)

    @app.route('/some/path/good')
    def safe(request):
        target = request.args.get('target', '')
        if SAFE_REGEX.match(target):
            return redirect(target)

    ```
    The `unsafe` check is easy to bypass because the unescaped `.` allows for any character before `example.com`, effectively allowing the redirect to go to an attacker-controlled domain such as `wwwXexample.com`.

    The `safe` check closes this vulnerability by escaping the `.` so that URLs of the form `wwwXexample.com` are rejected.

    # Incomplete URL substring sanitization
    Sanitizing untrusted URLs is a common technique for preventing attacks such as request forgeries and malicious redirections. Usually, this is done by checking that the host of a URL is in a set of allowed hosts.

    However, treating the URL as a string and checking if one of the allowed hosts is a substring of the URL is very prone to errors. Malicious URLs can bypass such security checks by embedding one of the allowed hosts in an unexpected location.

    Even if the substring check is not used in a security-critical context, the incomplete check may still cause undesirable behaviors when the check succeeds accidentally.


    ## Recommendation
    Parse a URL before performing a check on its host value, and ensure that the check handles arbitrary subdomain sequences correctly.


    ## Example
    The following example code checks that a URL redirection will reach the `example.com` domain.


    ```python
    from flask import Flask, request, redirect
    from urllib.parse import urlparse

    app = Flask(__name__)

    # Not safe, as "evil-example.net/example.com" would be accepted

    @app.route('/some/path/bad1')
    def unsafe1(request):
        target = request.args.get('target', '')
        if "example.com" in target:
            return redirect(target)

    # Not safe, as "benign-looking-prefix-example.com" would be accepted

    @app.route('/some/path/bad2')
    def unsafe2(request):
        target = request.args.get('target', '')
        if target.endswith("example.com"):
            return redirect(target)



    #Simplest and safest approach is to use an allowlist

    @app.route('/some/path/good1')
    def safe1(request):
        allowlist = [
            "example.com/home",
            "example.com/login",
        ]
        target = request.args.get('target', '')
        if target in allowlist:
            return redirect(target)

    #More complex example allowing sub-domains.

    @app.route('/some/path/good2')
    def safe2(request):
        target = request.args.get('target', '')
        host = urlparse(target).hostname
        #Note the '.' preceding example.com
        if host and host.endswith(".example.com"):
            return redirect(target)


    ```
    The first two examples show unsafe checks that are easily bypassed. In `unsafe1` the attacker can simply add `example.com` anywhere in the url. For example, `http://evil-example.net/example.com`.

    In `unsafe2` the attacker must use a hostname ending in `example.com`, but that is easy to do. For example, `http://benign-looking-prefix-example.com`.

    The second two examples show safe checks. In `safe1`, an allowlist is used. Although fairly inflexible, this is easy to get right and is most likely to be safe.

    In `safe2`, `urlparse` is used to parse the URL, then the hostname is checked to make sure it ends with `.example.com`.

    # Overly permissive regular expression range
    It's easy to write a regular expression range that matches a wider range of characters than you intended. For example, `/[a-zA-z]/` matches all lowercase and all uppercase letters, as you would expect, but it also matches the characters: `` [ \ ] ^ _ ` ``.

    Another common problem is failing to escape the dash character in a regular expression. An unescaped dash is interpreted as part of a range. For example, in the character class `[a-zA-Z0-9%=.,-_]` the last character range matches the 55 characters between `,` and `_` (both included), which overlaps with the range `[0-9]` and is clearly not intended by the writer.


    ## Recommendation
    Avoid any confusion about which characters are included in the range by writing unambiguous regular expressions. Always check that character ranges match only the expected characters.


    ## Example
    The following example code is intended to check whether a string is a valid 6 digit hex color.

    ```python

    import re
    def is_valid_hex_color(color):
        return re.match(r'^#[0-9a-fA-f]{6}$', color) is not None

    ```
    However, the `A-f` range is overly large and matches every uppercase character. It would parse a "color" like `#XXYYZZ` as valid.

    The fix is to use an uppercase `A-F` range instead.

    ```python

    import re
    def is_valid_hex_color(color):
        return re.match(r'^#[0-9a-fA-F]{6}$', color) is not None

    ```

    # Uncontrolled data used in path expression
    Accessing files using paths constructed from user-controlled data can allow an attacker to access unexpected resources. This can result in sensitive information being revealed or deleted, or an attacker being able to influence behavior by modifying unexpected files.


    ## Recommendation
    Validate paths constructed from untrusted user input before using them to access files.

    The choice of validation depends on the use case.

    If you want to allow paths spanning multiple folders, a common strategy is to make sure that the constructed file path is contained within a safe root folder. First, normalize the path using `os.path.normpath` or `os.path.realpath` (make sure to use the latter if symlinks are a consideration) to remove any internal ".." segments and/or follow links. Then check that the normalized path starts with the root folder. Note that the normalization step is important, since otherwise even a path that starts with the root folder could be used to access files outside the root folder.

    More restrictive options include using a library function like `werkzeug.utils.secure_filename` to eliminate any special characters from the file path, or restricting the path to a known list of safe paths. These options are safe, but can only be used in particular circumstances.


    ## Example
    In the first example, a file name is read from an HTTP request and then used to access a file. However, a malicious user could enter a file name that is an absolute path, such as `"/etc/passwd"`.

    In the second example, it appears that the user is restricted to opening a file within the `"user"` home directory. However, a malicious user could enter a file name containing special characters. For example, the string `"../../../etc/passwd"` will result in the code reading the file located at `"/server/static/images/../../../etc/passwd"`, which is the system's password file. This file would then be sent back to the user, giving them access to all the system's passwords. Note that a user could also use an absolute path here, since the result of `os.path.join("/server/static/images/", "/etc/passwd")` is `"/etc/passwd"`.

    In the third example, the path used to access the file system is normalized *before* being checked against a known prefix. This ensures that regardless of the user input, the resulting path is safe.


    ```python
    import os.path
    from flask import Flask, request, abort

    app = Flask(__name__)

    @app.route("/user_picture1")
    def user_picture1():
        filename = request.args.get('p')
        # BAD: This could read any file on the file system
        data = open(filename, 'rb').read()
        return data

    @app.route("/user_picture2")
    def user_picture2():
        base_path = '/server/static/images'
        filename = request.args.get('p')
        # BAD: This could still read any file on the file system
        data = open(os.path.join(base_path, filename), 'rb').read()
        return data

    @app.route("/user_picture3")
    def user_picture3():
        base_path = '/server/static/images'
        filename = request.args.get('p')
        #GOOD -- Verify with normalised version of path
        fullpath = os.path.normpath(os.path.join(base_path, filename))
        if not fullpath.startswith(base_path):
            raise Exception("not allowed")
        data = open(fullpath, 'rb').read()
        return data

    ```

    # Arbitrary file write during tarfile extraction
    Extracting files from a malicious tar archive without validating that the destination file path is within the destination directory can cause files outside the destination directory to be overwritten, due to the possible presence of directory traversal elements (`..`) in archive paths.

    Tar archives contain archive entries representing each file in the archive. These entries include a file path for the entry, but these file paths are not restricted and may contain unexpected special elements such as the directory traversal element (`..`). If these file paths are used to determine an output file to write the contents of the archive item to, then the file may be written to an unexpected location. This can result in sensitive information being revealed or deleted, or an attacker being able to influence behavior by modifying unexpected files.

    For example, if a tar archive contains a file entry `..\sneaky-file`, and the tar archive is extracted to the directory `c:\output`, then naively combining the paths would result in an output file path of `c:\output\..\sneaky-file`, which would cause the file to be written to `c:\sneaky-file`.


    ## Recommendation
    Ensure that output paths constructed from tar archive entries are validated to prevent writing files to unexpected locations.

    The recommended way of writing an output file from a tar archive entry is to check that `".."` does not occur in the path.


    ## Example
    In this example an archive is extracted without validating file paths. If `archive.tar` contained relative paths (for instance, if it were created by something like `tar -cf archive.tar ../file.txt`) then executing this code could write to locations outside the destination directory.


    ```python
    import sys
    import tarfile

    with tarfile.open(sys.argv[1]) as tar:
        #BAD : This could write any file on the filesystem.
        for entry in tar:
            tar.extract(entry, "/tmp/unpack/")

    ```
    To fix this vulnerability, we need to check that the path does not contain any `".."` elements in it.


    ```python
    import sys
    import tarfile
    import os.path

    with tarfile.open(sys.argv[1]) as tar:
        for entry in tar:
            #GOOD: Check that entry is safe
            if os.path.isabs(entry.name) or ".." in entry.name:
                raise ValueError("Illegal tar archive entry")
            tar.extract(entry, "/tmp/unpack/")

    ```

    # Uncontrolled command line
    Code that passes user input directly to `exec`, `eval`, or some other library routine that executes a command, allows the user to execute malicious code.


    ## Recommendation
    If possible, use hard-coded string literals to specify the command to run or the library to load. Instead of passing the user input directly to the process or library function, examine the user input and then choose among hard-coded string literals.

    If the applicable libraries or commands cannot be determined at compile time, then add code to verify that the user input string is safe before using it.


    ## Example
    The following example shows two functions. The first is unsafe as it takes a shell script that can be changed by a user, and passes it straight to `subprocess.call()` without examining it first. The second is safe as it selects the command from a predefined allowlist.


    ```python

    urlpatterns = [
        # Route to command_execution
        url(r'^command-ex1$', command_execution_unsafe, name='command-execution-unsafe'),
        url(r'^command-ex2$', command_execution_safe, name='command-execution-safe')
    ]

    COMMANDS = {
        "list" :"ls",
        "stat" : "stat"
    }

    def command_execution_unsafe(request):
        if request.method == 'POST':
            action = request.POST.get('action', '')
            #BAD -- No sanitizing of input
            subprocess.call(["application", action])

    def command_execution_safe(request):
        if request.method == 'POST':
            action = request.POST.get('action', '')
            #GOOD -- Use an allowlist
            subprocess.call(["application", COMMANDS[action]])

    # Jinja2 templating with autoescape=False
    Cross-site scripting (XSS) attacks can occur if untrusted input is not escaped. This applies to templates as well as code. The `jinja2` templates may be vulnerable to XSS if the environment has `autoescape` set to `False`. Unfortunately, `jinja2` sets `autoescape` to `False` by default. Explicitly setting `autoescape` to `True` when creating an `Environment` object will prevent this.


    ## Recommendation
    Avoid setting jinja2 autoescape to False. Jinja2 provides the function `select_autoescape` to make sure that the correct auto-escaping is chosen. For example, it can be used when creating an environment `Environment(autoescape=select_autoescape(['html', 'xml'])`


    ## Example
    The following example is a minimal Flask app which shows a safe and an unsafe way to render the given name back to the page. The first view is unsafe as `first_name` is not escaped, leaving the page vulnerable to cross-site scripting attacks. The second view is safe as `first_name` is escaped, so it is not vulnerable to cross-site scripting attacks.


    ```python
    from flask import Flask, request, make_response, escape
    from jinja2 import Environment, select_autoescape, FileSystemLoader

    app = Flask(__name__)
    loader = FileSystemLoader( searchpath="templates/" )

    unsafe_env = Environment(loader=loader)
    safe1_env = Environment(loader=loader, autoescape=True)
    safe2_env = Environment(loader=loader, autoescape=select_autoescape())

    def render_response_from_env(env):
        name = request.args.get('name', '')
        template = env.get_template('template.html')
        return make_response(template.render(name=name))

    @app.route('/safe2')

    # Reflected server-side cross-site scripting
    Directly writing user input (for example, an HTTP request parameter) to a webpage without properly sanitizing the input first, allows for a cross-site scripting vulnerability.


    ## Recommendation
    To guard against cross-site scripting, consider escaping the input before writing user input to the page. The standard library provides escaping functions: `html.escape()` for Python 3.2 upwards or `cgi.escape()` older versions of Python. Most frameworks also provide their own escaping functions, for example `flask.escape()`.


    ## Example
    The following example is a minimal flask app which shows a safe and unsafe way to render the given name back to the page. The first view is unsafe as `first_name` is not escaped, leaving the page vulnerable to cross-site scripting attacks. The second view is safe as `first_name` is escaped, so it is not vulnerable to cross-site scripting attacks.


    ```python
    from flask import Flask, request, make_response, escape

    app = Flask(__name__)

    @app.route('/unsafe')
    def unsafe():
        first_name = request.args.get('name', '')
        return make_response("Your name is " + first_name)

    @app.route('/safe')
    def safe():
        first_name = request.args.get('name', '')
        return make_response("Your name is " + escape(first_name))

    # SQL query built from user-controlled sources
    If a database query (such as a SQL or NoSQL query) is built from user-provided data without sufficient sanitization, a user may be able to run malicious database queries.

    This also includes using the `TextClause` class in the `[SQLAlchemy](https://pypi.org/project/SQLAlchemy/)` PyPI package, which is used to represent a literal SQL fragment and is inserted directly into the final SQL when used in a query built using the ORM.


    ## Recommendation
    Most database connector libraries offer a way of safely embedding untrusted data into a query by means of query parameters or prepared statements.


    ## Example
    In the following snippet, a user is fetched from the database using three different queries.

    In the first case, the query string is built by directly using string formatting from a user-supplied request parameter. The parameter may include quote characters, so this code is vulnerable to a SQL injection attack.

    In the second case, the user-supplied request attribute is passed to the database using query parameters. The database connector library will take care of escaping and inserting quotes as needed.

    In the third case, the placeholder in the SQL string has been manually quoted. Since most databaseconnector libraries will insert their own quotes, doing so yourself will make the code vulnerable to SQL injection attacks. In this example, if `username` was `; DROP ALL TABLES -- `, the final SQL query would be `SELECT * FROM users WHERE username = ''; DROP ALL TABLES -- ''`


    ```python
    from django.conf.urls import url
    from django.db import connection


    def show_user(request, username):
        with connection.cursor() as cursor:
            # BAD -- Using string formatting
            cursor.execute("SELECT * FROM users WHERE username = '%s'" % username)
            user = cursor.fetchone()

            # GOOD -- Using parameters
            cursor.execute("SELECT * FROM users WHERE username = %s", username)
            user = cursor.fetchone()

            # BAD -- Manually quoting placeholder (%s)
            cursor.execute("SELECT * FROM users WHERE username = '%s'", username)
            user = cursor.fetchone()

    urlpatterns = [url(r'^users/(?P<username>[^/]+)$', show_user)]

    # LDAP query built from user-controlled sources
    If an LDAP query or DN is built using string concatenation or string formatting, and the components of the concatenation include user input without any proper sanitization, a user is likely to be able to run malicious LDAP queries.


    ## Recommendation
    If user input must be included in an LDAP query or DN, it should be escaped to avoid a malicious user providing special characters that change the meaning of the query. In Python2, user input should be escaped with `ldap.dn.escape_dn_chars` or `ldap.filter.escape_filter_chars`, while in Python3, user input should be escaped with `ldap3.utils.dn.escape_rdn` or `ldap3.utils.conv.escape_filter_chars` depending on the component tainted by the user. A good practice is to escape filter characters that could change the meaning of the query (https://tools.ietf.org/search/rfc4515\#section-3).


    ## Example
    In the following examples, the code accepts both `username` and `dc` from the user, which it then uses to build a LDAP query and DN.

    The first and the second example uses the unsanitized user input directly in the search filter and DN for the LDAP query. A malicious user could provide special characters to change the meaning of these components, and search for a completely different set of values.


    ```python
    from flask import request, Flask
    import ldap


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        dn = "dc={}".format(unsafe_dc)
        search_filter = "(user={})".format(unsafe_filter)

        ldap_connection = ldap.initialize("ldap://127.0.0.1")
        user = ldap_connection.search_s(
            dn, ldap.SCOPE_SUBTREE, search_filter)

    ```

    ```python
    from flask import request, Flask
    import ldap3


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        dn = "dc={}".format(unsafe_dc)
        search_filter = "(user={})".format(unsafe_filter)

        srv = ldap3.Server('ldap://127.0.0.1')
        conn = ldap3.Connection(srv, user=dn, auto_bind=True)
        conn.search(dn, search_filter)

    ```
    In the third and fourth example, the input provided by the user is sanitized before it is included in the search filter or DN. This ensures the meaning of the query cannot be changed by a malicious user.


    ```python
    from flask import request, Flask
    import ldap
    import ldap.filter
    import ldap.dn


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        safe_dc = ldap.dn.escape_dn_chars(unsafe_dc)
        safe_filter = ldap.filter.escape_filter_chars(unsafe_filter)

        dn = "dc={}".format(safe_dc)
        search_filter = "(user={})".format(safe_filter)

        ldap_connection = ldap.initialize("ldap://127.0.0.1")
        user = ldap_connection.search_s(
            dn, ldap.SCOPE_SUBTREE, search_filter)

    ```

    ```python
    from flask import request, Flask
    import ldap3
    from ldap3.utils.dn import escape_rdn
    from ldap3.utils.conv import escape_filter_chars


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        safe_dc = escape_rdn(unsafe_dc)
        safe_filter = escape_filter_chars(unsafe_filter)

        dn = "dc={}".format(safe_dc)
        search_filter = "(user={})".format(safe_filter)

        srv = ldap3.Server('ldap://127.0.0.1')
        conn = ldap3.Connection(srv, user=dn, auto_bind=True)
        conn.search(dn, search_filter)

    # Code injection
    Directly evaluating user input (for example, an HTTP request parameter) as code without properly sanitizing the input first allows an attacker arbitrary code execution. This can occur when user input is passed to code that interprets it as an expression to be evaluated, such as `eval` or `exec`.


    ## Recommendation
    Avoid including user input in any expression that may be dynamically evaluated. If user input must be included, use context-specific escaping before including it. It is important that the correct escaping is used for the type of evaluation that will occur.


    ## Example
    The following example shows two functions setting a name from a request. The first function uses `exec` to execute the `setname` function. This is dangerous as it can allow a malicious user to execute arbitrary code on the server. For example, the user could supply the value `"' + subprocess.call('rm -rf') + '"` to destroy the server's file system. The second function calls the `setname` function directly and is thus safe.


    ```python

    urlpatterns = [
        # Route to code_execution
        url(r'^code-ex1$', code_execution_bad, name='code-execution-bad'),
        url(r'^code-ex2$', code_execution_good, name='code-execution-good')
    ]

    def code_execution(request):
        if request.method == 'POST':
            first_name = base64.decodestring(request.POST.get('first_name', ''))
            #BAD -- Allow user to define code to be run.

    \ by a browser if the string is rendered as HTML.\n\nOther corner cases include\

    # Log Injection
    If unsanitized user input is written to a log entry, a malicious user may be able to forge new log entries.

    Forgery can occur if a user provides some input with characters that are interpreted when the log output is displayed. If the log is displayed as a plain text file, then new line characters can be used by a malicious user to create the appearance of multiple log entries. If the log is displayed as HTML, then arbitrary HTML may be included to spoof log entries.


    ## Recommendation
    User input should be suitably sanitized before it is logged.

    If the log entries are plain text then line breaks should be removed from user input, using for example `replace(old, new)` or similar. Care should also be taken that user input is clearly marked in log entries, and that a malicious user cannot cause confusion in other ways.

    For log entries that will be displayed in HTML, user input should be HTML encoded before being logged, to prevent forgery and other forms of HTML injection.


    ## Example
    In the example, the name provided by the user is recorded using the log output function (`logging.info` or `app.logger.info`, etc.). In these four cases, the name provided by the user is not provided The processing is recorded. If a malicious user provides `Guest%0D%0AUser name: Admin` as a parameter, the log entry will be divided into two lines, the first line is `User name: Guest` code&gt;, the second line is `User name: Admin`.

    app = Flask(__name__)

    @app.route('/bad1')
    def bad1():
        name = request.args.get('name')
        app.logger.info('User name: ' + name) # Bad
        return 'bad1'

    @app.route('/bad2')
    def bad2():

    def bad3():

        app.debug = True
        handler = logging.FileHandler('log')
        app.logger.addHandler(handler)
        app.run()

    ```
    In a good example, the program uses the `replace` function to provide parameter processing to the user, and replace `\r\n` and `\n` with empty characters. To a certain extent, the occurrence of log injection vulnerabilities is reduced.

    # Information exposure through an exception
    Software developers often add stack traces to error messages, as a debugging aid. Whenever that error message occurs for an end user, the developer can use the stack trace to help identify how to fix the problem. In particular, stack traces can tell the developer more about the sequence of events that led to a failure, as opposed to merely the final state of the software when the error occurred.

    Unfortunately, the same information can be useful to an attacker. The sequence of class names in a stack trace can reveal the structure of the application as well as any internal components it relies on. Furthermore, the error message at the top of a stack trace can include information such as server-side file names and SQL code that the application relies on, allowing an attacker to fine-tune a subsequent injection attack.


    ## Recommendation
    Send the user a more generic error message that reveals less information. Either suppress the stack trace entirely, or log it only on the server.


    ## Example
    In the following example, an exception is handled in two different ways. In the first version, labeled BAD, the exception is sent back to the remote user by returning it from the function. As such, the user is able to see a detailed stack trace, which may contain sensitive information. In the second version, the error message is logged only on the server, and a generic error message is displayed to the user. That way, the developers can still access and use the error log, but remote users will not see the information.


    ```python
    from flask import Flask
    app = Flask(__name__)


    import traceback

    def do_computation():
        raise Exception("Secret info")

    # BAD
    @app.route('/bad')
    def server_bad():
        try:
            do_computation()
        except Exception as e:
            return traceback.format_exc()

    # GOOD
    @app.route('/good')
    def server_good():
        try:
            do_computation()
        except Exception as e:
            log(traceback.format_exc())
            return "An internal error has occurred!"

    ```

    ## Example
    Running the following code starts a Flask webserver that has debugging enabled. By visiting `/crash`, it is possible to gain access to the debugger, and run arbitrary code through the interactive debugger.

    # PAM authorization bypass due to incorrect usage
    Using only a call to `pam_authenticate` to check the validity of a login can lead to authorization bypass vulnerabilities.

    A `pam_authenticate` only verifies the credentials of a user. It does not check if a user has an appropriate authorization to actually login. This means a user with an expired login or a password can still access the system.


    ## Recommendation
    A call to `pam_authenticate` should be followed by a call to `pam_acct_mgmt` to check if a user is allowed to login.


    ## Example
    In the following example, the code only checks the credentials of a user. Hence, in this case, a user with expired credentials can still login. This can be verified by creating a new user account, expiring it with ``` chage -E0 `username`  ``` and then trying to log in.


    ```python
    libpam                    = CDLL(find_library("pam"))

    # Accepting unknown SSH host keys when using Paramiko
    In the Secure Shell (SSH) protocol, host keys are used to verify the identity of remote hosts. Accepting unknown host keys may leave the connection open to man-in-the-middle attacks.


    ## Recommendation
    Do not accept unknown host keys. In particular, do not set the default missing host key policy for the Paramiko library to either `AutoAddPolicy` or `WarningPolicy`. Both of these policies continue even when the host key is unknown. The default setting of `RejectPolicy` is secure because it throws an exception when it encounters an unknown host key.


    ## Example
    The following example shows two ways of opening an SSH connection to `example.com`. The first function sets the missing host key policy to `AutoAddPolicy`. If the host key verification fails, the client will continue to interact with the server, even though the connection may be compromised. The second function sets the host key policy to `RejectPolicy`, and will throw an exception if the host key verification fails.


    ```python
    from paramiko.client import SSHClient, AutoAddPolicy, RejectPolicy

    def unsafe_connect():
        client = SSHClient()
        client.set_missing_host_key_policy(AutoAddPolicy)
        client.connect("example.com")

        # ... interaction with server

        client.close()

    def safe_connect():
        client = SSHClient()
        client.set_missing_host_key_policy(RejectPolicy)
        client.connect("example.com")

        # ... interaction with server

        client.close()

    ```

    # Request without certificate validation
    Encryption is key to the security of most, if not all, online communication. Using Transport Layer Security (TLS) can ensure that communication cannot be interrupted by an interloper. For this reason, it is unwise to disable the verification that TLS provides. Functions in the `requests` module provide verification by default, and it is only when explicitly turned off using `verify=False` that no verification occurs.


    ## Recommendation
    Never use `verify=False` when making a request.


    ## Example
    The example shows two unsafe calls to [semmle.com](https://semmle.com), followed by various safe alternatives.


    ```python
    import requests

    #Unsafe requests

    requests.get('https://semmle.com', verify=False) # UNSAFE
    requests.get('https://semmle.com', verify=0) # UNSAFE

    #Various safe options

    requests.get('https://semmle.com', verify=True) # Explicitly safe
    requests.get('https://semmle.com', verify="/path/to/cert/")
    requests.get('https://semmle.com') # The default is to verify.

    #Wrapper to ensure safety

    def make_safe_request(url, verify_cert):
        if not verify_cert:
            raise Exception("Trying to make unsafe request")
        return requests.get(url, verify_cert)

    ```

    # Clear-text logging of sensitive information
    If sensitive data is written to a log entry it could be exposed to an attacker who gains access to the logs.

    Potential attackers can obtain sensitive user data when the log output is displayed. Additionally that data may expose system information such as full path names, system information, and sometimes usernames and passwords.


    ## Recommendation
    Sensitive data should not be logged.


    ## Example
    In the example the entire process environment is logged using \`print\`. Regular users of the production deployed application should not have access to this much information about the environment configuration.


    ```python
    # BAD: Logging cleartext sensitive data
    import os
    print(f"[INFO] Environment: {os.environ}")
    ```
    In the second example the data that is logged is not sensitive.


    ```python
    not_sensitive_data = {'a': 1, 'b': 2}
    # GOOD: it is fine to log data that is not sensitive
    print(f"[INFO] Some object contains: {not_sensitive_data}")

    # Clear-text storage of sensitive information
    Sensitive information that is stored unencrypted is accessible to an attacker who gains access to the storage. This is particularly important for cookies, which are stored on the machine of the end-user.


    ## Recommendation
    Ensure that sensitive information is always encrypted before being stored. If possible, avoid placing sensitive information in cookies altogether. Instead, prefer storing, in the cookie, a key that can be used to look up the sensitive information.

    In general, decrypt sensitive information only at the point where it is necessary for it to be used in cleartext.

    Be aware that external processes often store the `standard out` and `standard error` streams of the application, causing logged sensitive information to be stored as well.


    ## Example
    The following example code stores user credentials (in this case, their password) in a cookie in plain text:


    ```python
    from flask import Flask, make_response, request

    app = Flask("Leak password")

    @app.route('/')
    def index():
        password = request.args.get("password")
        resp = make_response(render_template(...))
        resp.set_cookie("password", password)
        return resp

    ```
    Instead, the credentials should be encrypted, for instance by using the `cryptography` module, or not stored at all.

    # Use of weak cryptographic key
    Modern encryption relies on it being computationally infeasible to break the cipher and decode a message without the key. As computational power increases, the ability to break ciphers grows and keys need to become larger.

    The three main asymmetric key algorithms currently in use are Rivest–Shamir–Adleman (RSA) cryptography, Digital Signature Algorithm (DSA), and Elliptic-curve cryptography (ECC). With current technology, key sizes of 2048 bits for RSA and DSA, or 256 bits for ECC, are regarded as unbreakable.


    ## Recommendation
    Increase the key size to the recommended amount or larger. For RSA or DSA this is at least 2048 bits, for ECC this is at least 256 bits.

    # Use of a broken or weak cryptographic algorithm
    Using broken or weak cryptographic algorithms may compromise security guarantees such as confidentiality, integrity, and authenticity.

    Many cryptographic algorithms are known to be weak or flawed. The security guarantees of a system often rely on the underlying cryptography, so using a weak algorithm can have severe consequences. For example:

    * If a weak encryption algorithm is used, an attacker may be able to decrypt sensitive data.
    * If a weak algorithm is used for digital signatures, an attacker may be able to forge signatures and impersonate legitimate users.
    This query alerts on any use of a weak cryptographic algorithm that is not a hashing algorithm. Use of broken or weak cryptographic hash functions are handled by the `py/weak-sensitive-data-hashing` query.


    ## Recommendation
    Ensure that you use a strong, modern cryptographic algorithm, such as AES-128 or RSA-2048.


    ## Example
    The following code uses the `pycryptodome` library to encrypt some secret data. When you create a cipher using `pycryptodome` you must specify the encryption algorithm to use. The first example uses DES, which is an older algorithm that is now considered weak. The second example uses AES, which is a stronger modern algorithm.


    ```python
    from Crypto.Cipher import DES, AES

    cipher = DES.new(SECRET_KEY)

    def send_encrypted(channel, message):
        channel.send(cipher.encrypt(message)) # BAD: weak encryption


    cipher = AES.new(SECRET_KEY)

    def send_encrypted(channel, message):
        channel.send(cipher.encrypt(message)) # GOOD: strong encryption


    ```
    NOTICE: the original `[pycrypto](https://pypi.org/project/pycrypto/)` PyPI package that provided the `Crypto` module is not longer actively maintained, so you should use the `[pycryptodome](https://pypi.org/project/pycryptodome/)` PyPI package instead (which has a compatible API).

    # Default version of SSL/TLS may be insecure
    The `ssl.wrap_socket` function defaults to an insecure version of SSL/TLS when no specific protocol version is specified. This may leave the connection vulnerable to attack.


    ## Recommendation
    Ensure that a modern, strong protocol is used. All versions of SSL, and TLS 1.0 and 1.1 are known to be vulnerable to attacks. Using TLS 1.2 or above is strongly recommended. If no explicit `ssl_version` is specified, the default `PROTOCOL_TLS` is chosen. This protocol is insecure because it allows TLS 1.0 and TLS 1.1 and so should not be used.


    ## Example
    The following code shows two different ways of setting up a connection using SSL or TLS. They are both potentially insecure because the default version is used.


    ```python
    import ssl
    import socket

    # Using the deprecated ssl.wrap_socket method
    ssl.wrap_socket(socket.socket())

    # Using SSLContext
    context = ssl.SSLContext()

    ```
    Both of the cases above should be updated to use a secure protocol instead, for instance by specifying `ssl_version=PROTOCOL_TLSv1_2` as a keyword argument.

    The latter example can also be made secure by modifying the created context before it is used to create a connection. Therefore it will not be flagged by this query. However, if a connection is created before the context has been secured (for example, by setting the value of `minimum_version`), then the code should be flagged by the query `py/insecure-protocol`.

    Note that `ssl.wrap_socket` has been deprecated in Python 3.7. The recommended alternatives are:

    * `ssl.SSLContext` - supported in Python 2.7.9, 3.2, and later versions
    * `ssl.create_default_context` - a convenience function, supported in Python 3.4 and later versions.
    Even when you use these alternatives, you should ensure that a safe protocol is used. The following code illustrates how to use flags (available since Python 3.2) or the \`minimum_version\` field (favored since Python 3.7) to restrict the protocols accepted when creating a connection.


    ```python
    import ssl

    # Using flags to restrict the protocol
    context = ssl.SSLContext()
    context.options |= ssl.OP_NO_TLSv1 | ssl.OP_NO_TLSv1_1

    # Declaring a minimum version to restrict the protocol
    context = ssl.create_default_context()
    context.minimum_version = ssl.TLSVersion.TLSv1_2

    ```

    # Use of a broken or weak cryptographic hashing algorithm on sensitive data
    Using a broken or weak cryptographic hash function can leave data vulnerable, and should not be used in security related code.

    A strong cryptographic hash function should be resistant to:

    * pre-image attacks: if you know a hash value `h(x)`, you should not be able to easily find the input `x`.
    * collision attacks: if you know a hash value `h(x)`, you should not be able to easily find a different input `y` with the same hash value `h(x) = h(y)`.
    In cases with a limited input space, such as for passwords, the hash function also needs to be computationally expensive to be resistant to brute-force attacks. Passwords should also have an unique salt applied before hashing, but that is not considered by this query.

    As an example, both MD5 and SHA-1 are known to be vulnerable to collision attacks.

    Since it's OK to use a weak cryptographic hash function in a non-security context, this query only alerts when these are used to hash sensitive data (such as passwords, certificates, usernames).

    Use of broken or weak cryptographic algorithms that are not hashing algorithms, is handled by the `py/weak-cryptographic-algorithm` query.


    ## Recommendation
    Ensure that you use a strong, modern cryptographic hash function:

    * such as Argon2, scrypt, bcrypt, or PBKDF2 for passwords and other data with limited input space.
    * such as SHA-2, or SHA-3 in other cases.

    ## Example
    The following example shows two functions for checking whether the hash of a certificate matches a known value -- to prevent tampering. The first function uses MD5 that is known to be vulnerable to collision attacks. The second function uses SHA-256 that is a strong cryptographic hashing function.


    ```python
    import hashlib

    def certificate_matches_known_hash_bad(certificate, known_hash):
        hash = hashlib.md5(certificate).hexdigest() # BAD
        return hash == known_hash

    def certificate_matches_known_hash_good(certificate, known_hash):
        hash = hashlib.sha256(certificate).hexdigest() # GOOD
        return hash == known_hash

    ```

    ## Example
    The following example shows two functions for hashing passwords. The first function uses SHA-256 to hash passwords. Although SHA-256 is a strong cryptographic hash function, it is not suitable for password hashing since it is not computationally expensive.


    ```python
    import hashlib

    def get_password_hash(password: str, salt: str):
        return hashlib.sha256(password + salt).hexdigest() # BAD

    ```
    The second function uses Argon2 (through the `argon2-cffi` PyPI package), which is a strong password hashing algorithm (and includes a per-password salt by default).


    ```python
    from argon2 import PasswordHasher

    def get_initial_hash(password: str):
        ph = PasswordHasher()
        return ph.hash(password) # GOOD

    def check_password(password: str, known_hash):
        ph = PasswordHasher()
        return ph.verify(known_hash, password) # GOOD

    ```

    # CSRF protection weakened or disabled
    Cross-site request forgery (CSRF) is a type of vulnerability in which an attacker is able to force a user to carry out an action that the user did not intend.

    The attacker tricks an authenticated user into submitting a request to the web application. Typically this request will result in a state change on the server, such as changing the user's password. The request can be initiated when the user visits a site controlled by the attacker. If the web application relies only on cookies for authentication, or on other credentials that are automatically included in the request, then this request will appear as legitimate to the server.

    A common countermeasure for CSRF is to generate a unique token to be included in the HTML sent from the server to a user. This token can be used as a hidden field to be sent back with requests to the server, where the server can then check that the token is valid and associated with the relevant user session.


    ## Recommendation
    In many web frameworks, CSRF protection is enabled by default. In these cases, using the default configuration is sufficient to guard against most CSRF attacks.


    ## Example
    The following example shows a case where CSRF protection is disabled by overriding the default middleware stack and not including the one protecting against CSRF.


    ```python
    MIDDLEWARE = [
        'django.middleware.security.SecurityMiddleware',
        'django.contrib.sessions.middleware.SessionMiddleware',
        'django.middleware.common.CommonMiddleware',
        # 'django.middleware.csrf.CsrfViewMiddleware',
        'django.contrib.auth.middleware.AuthenticationMiddleware',
        'django.contrib.messages.middleware.MessageMiddleware',
        'django.middleware.clickjacking.XFrameOptionsMiddleware',
    ]

    ```
    The protecting middleware was probably commented out during a testing phase, when server-side token generation was not set up. Simply commenting it back in will enable CSRF protection.

    # Insecure temporary file
    Functions that create temporary file names (such as `tempfile.mktemp` and `os.tempnam`) are fundamentally insecure, as they do not ensure exclusive access to a file with the temporary name they return. The file name returned by these functions is guaranteed to be unique on creation but the file must be opened in a separate operation. There is no guarantee that the creation and open operations will happen atomically. This provides an opportunity for an attacker to interfere with the file before it is opened.

    Note that `mktemp` has been deprecated since Python 2.3.


    ## Recommendation
    Replace the use of `mktemp` with some of the more secure functions in the `tempfile` module, such as `TemporaryFile`. If the file is intended to be accessed from other processes, consider using the `NamedTemporaryFile` function.


    ## Example
    The following piece of code opens a temporary file and writes a set of results to it. Because the file name is created using `mktemp`, another process may access this file before it is opened using `open`.


    ```python
    from tempfile import mktemp

    def write_results(results):
        filename = mktemp()
        with open(filename, "w+") as f:
            f.write(results)
        print("Results written to", filename)

    ```
    By changing the code to use `NamedTemporaryFile` instead, the file is opened immediately.


    ```python
    from tempfile import NamedTemporaryFile

    def write_results(results):
        with NamedTemporaryFile(mode="w+", delete=False) as f:
            f.write(results)
        print("Results written to", f.name)

    ```

    # Deserialization of user-controlled data
    Deserializing untrusted data using any deserialization framework that allows the construction of arbitrary serializable objects is easily exploitable and in many cases allows an attacker to execute arbitrary code. Even before a deserialized object is returned to the caller of a deserialization method a lot of code may have been executed, including static initializers, constructors, and finalizers. Automatic deserialization of fields means that an attacker may craft a nested combination of objects on which the executed initialization code may have unforeseen effects, such as the execution of arbitrary code.

    There are many different serialization frameworks. This query currently supports Pickle, Marshal and Yaml.


    ## Recommendation
    Avoid deserialization of untrusted data if at all possible. If the architecture permits it then use other formats instead of serialized objects, for example JSON.

    If you need to use YAML, use the `yaml.safe_load` function.


    ## Example
    The following example calls `pickle.loads` directly on a value provided by an incoming HTTP request. Pickle then creates a new value from untrusted data, and is therefore inherently unsafe.


    ```python

    from django.conf.urls import url
    import pickle

    def unsafe(pickled):
        return pickle.loads(pickled)

    urlpatterns = [
        url(r'^(?P<object>.*)$', unsafe)
    ]
    ```
    Changing the code to use `json.loads` instead of `pickle.loads` removes the vulnerability.


    ```python

    from django.conf.urls import url
    import json

    def safe(pickled):
        return json.loads(pickled)

    urlpatterns = [
        url(r'^(?P<object>.*)$', safe)
    ]

    ```

    # URL redirection from remote source
    Directly incorporating user input into a URL redirect request without validating the input can facilitate phishing attacks. In these attacks, unsuspecting users can be redirected to a malicious site that looks very similar to the real site they intend to visit, but which is controlled by the attacker.


    ## Recommendation
    To guard against untrusted URL redirection, it is advisable to avoid putting user input directly into a redirect URL. Instead, maintain a list of authorized redirects on the server; then choose from that list based on the user input provided.

    If this is not possible, then the user input should be validated in some other way, for example, by verifying that the target URL does not include an explicit host name.


    ## Example
    The following example shows an HTTP request parameter being used directly in a URL redirect without validating the input, which facilitates phishing attacks:


    ```python
    from flask import Flask, request, redirect

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        return redirect(target, code=302)

    ```
    If you know the set of valid redirect targets, you can maintain a list of them on the server and check that the user input is in that list:


    ```python
    from flask import Flask, request, redirect

    VALID_REDIRECT = "http://cwe.mitre.org/data/definitions/601.html"

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        if target == VALID_REDIRECT:
            return redirect(target, code=302)
        else:
            # ignore the target and redirect to the home page
            return redirect('/', code=302)

    ```
    Often this is not possible, so an alternative is to check that the target URL does not specify an explicit host name. For example, you can use the `urlparse` function from the Python standard library to parse the URL and check that the `netloc` attribute is empty.

    Note, however, that some cases are not handled as we desire out-of-the-box by `urlparse`, so we need to adjust two things, as shown in the example below:

    * Many browsers accept backslash characters (`\`) as equivalent to forward slash characters (`/`) in URLs, but the `urlparse` function does not.
    * Mistyped URLs such as `https:/example.com` or `https:///example.com` are parsed as having an empty `netloc` attribute, while browsers will still redirect to the correct site.

    ```python
    from flask import Flask, request, redirect
    from urllib.parse import urlparse

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        target = target.replace('\\', '')
        if not urlparse(target).netloc and not urlparse(target).scheme:
            # relative path, safe to redirect
            return redirect(target, code=302)
        # ignore the target and redirect to the home page
        return redirect('/', code=302)

    ```
    For Django application, you can use the function `url_has_allowed_host_and_scheme` to check that a URL is safe to redirect to, as shown in the following example:


    ```python
    from django.http import HttpResponseRedirect
    from django.shortcuts import redirect
    from django.utils.http import url_has_allowed_host_and_scheme
    from django.views import View

    class RedirectView(View):
        def get(self, request, *args, **kwargs):
            target = request.GET.get('target', '')
            if url_has_allowed_host_and_scheme(target, allowed_hosts=None):
                return HttpResponseRedirect(target)
            else:
                # ignore the target and redirect to the home page
                return redirect('/')
    ```
    Note that `url_has_allowed_host_and_scheme` handles backslashes correctly, so no additional processing is required.

    # XML external entity expansion
    Parsing untrusted XML files with a weakly configured XML parser may lead to an XML External Entity (XXE) attack. This type of attack uses external entity references to access arbitrary files on a system, carry out denial-of-service (DoS) attacks, or server-side request forgery. Even when the result of parsing is not returned to the user, DoS attacks are still possible and out-of-band data retrieval techniques may allow attackers to steal sensitive data.


    ## Recommendation
    The easiest way to prevent XXE attacks is to disable external entity handling when parsing untrusted data. How this is done depends on the library being used. Note that some libraries, such as recent versions of the XML libraries in the standard library of Python 3, disable entity expansion by default, so unless you have explicitly enabled entity expansion, no further action needs to be taken.

    We recommend using the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package, which has been created to prevent XML attacks (both XXE and XML bombs).


    ## Example
    The following example uses the `lxml` XML parser to parse a string `xml_src`. That string is from an untrusted source, so this code is vulnerable to an XXE attack, since the [ default parser](https://lxml.de/apidoc/lxml.etree.html#lxml.etree.XMLParser) from `lxml.etree` allows local external entities to be resolved.


    ```python
    from flask import Flask, request
    import lxml.etree

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = lxml.etree.fromstring(xml_src)
        return lxml.etree.tostring(doc)

    ```
    To guard against XXE attacks with the `lxml` library, you should create a parser with `resolve_entities` set to `false`. This means that no entity expansion is undertaken, although standard predefined entities such as `&gt;`, for writing `>` inside the text of an XML element, are still allowed.


    ```python
    from flask import Flask, request
    import lxml.etree

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        parser = lxml.etree.XMLParser(resolve_entities=False)
        doc = lxml.etree.fromstring(xml_src, parser=parser)
        return lxml.etree.tostring(doc)

    ```

    # XPath query built from user-controlled sources
    If an XPath expression is built using string concatenation, and the components of the concatenation include user input, it makes it very easy for a user to create a malicious XPath expression.


    ## Recommendation
    If user input must be included in an XPath expression, either sanitize the data or use variable references to safely embed it without altering the structure of the expression.


    ## Example
    In the example below, the xpath query is controlled by the user and hence leads to a vulnerability.


    ```python
    from lxml import etree
    from io import StringIO

    from django.urls import path
    from django.http import HttpResponse
    from django.template import Template, Context, Engine, engines


    def a(request):
        value = request.GET['xpath']
        f = StringIO('<foo><bar></bar></foo>')
        tree = etree.parse(f)
        r = tree.xpath("/tag[@id='%s']" % value)


    urlpatterns = [
        path('a', a)
    ]

    ```
    This can be fixed by using a parameterized query as shown below.


    ```python
    from lxml import etree
    from io import StringIO

    from django.urls import path
    from django.http import HttpResponse
    from django.template import Template, Context, Engine, engines


    def a(request):
        value = request.GET['xpath']
        f = StringIO('<foo><bar></bar></foo>')
        tree = etree.parse(f)
        r = tree.xpath("/tag[@id=$tagid]", tagid=value)


    urlpatterns = [
        path('a', a)
    ]

    \nThe regular expression engine provided by Python uses a backtracking non-deterministic\

    \ of a certain shape, increasing the input length by ten characters may make the\
    \ automaton about 1000 times slower.\n\nTypically, a regular expression is affected\
    \ by this problem if it contains a repetition of the form `r*` or `r+` where the\

    \ in the references.\n\n\n## Recommendation\nModify the regular expression to\
    \ remove the ambiguity, or ensure that the strings matched with the regular expression\
    \ are short enough that the time-complexity does not matter.\n\n\n## Example\n\
    Consider this use of a regular expression, which removes all leading and trailing\
    \ whitespace in a string:\n\n```python\n\nre.sub(r\"^\\s+|\\s+$\", \"\", text)\
    \ # BAD\n```\nThe sub-expression `\"\\s+$\"` will match the whitespace characters\
    \ in `text` from left to right, but it can start matching anywhere within a whitespace\
    \ sequence. This is problematic for strings that do **not** end with a whitespace\
    \ character. Such a string will force the regular expression engine to process\
    \ each whitespace sequence once per whitespace character in the sequence.\n\n\
    This ultimately means that the time cost of trimming a string is quadratic in\
    \ the length of the string. So a string like `\"a b\"` will take milliseconds\
    \ to process, but a similar string with a million spaces instead of just one will\
    \ take several minutes.\n\nAvoid this problem by rewriting the regular expression\
    \ to not contain the ambiguity about when to start matching whitespace sequences.\
    \ For instance, by using a negative look-behind (`^\\s+|(?<!\\s)\\s+$`), or just\
    \ by using the built-in strip method (`text.strip()`).\n\nNote that the sub-expression\
    \ `\"^\\s+\"` is **not** problematic as the `^` anchor restricts when that sub-expression\
    \ can start matching, and as the regular expression engine matches from left to\
    \ right.\n\n\n## Example\nAs a similar, but slightly subtler problem, consider\
    \ the regular expression that matches lines with numbers, possibly written using\
    \ scientific notation:\n\n```python\n\n^0\\.\\d+E?\\d+$ # BAD\n```\nThe problem\
    \ with this regular expression is in the sub-expression `\\d+E?\\d+` because the\
    \ second `\\d+` can start matching digits anywhere after the first match of the\
    \ first `\\d+` if there is no `E` in the input string.\n\nThis is problematic\
    \ for strings that do **not** end with a digit. Such a string will force the regular\
    \ expression engine to process each digit sequence once per digit in the sequence,\
    \ again leading to a quadratic time complexity.\n\nTo make the processing faster,\
    \ the regular expression should be rewritten such that the two `\\d+` sub-expressions\
    \ do not have overlapping matches: `^0\\.\\d+(E\\d+)?$`.\n\n\n## Example\nSometimes\
    \ it is unclear how a regular expression can be rewritten to avoid the problem.\
    \ In such cases, it often suffices to limit the length of the input string. For\
    \ instance, the following regular expression is used to match numbers, and on\
    \ some non-number inputs it can have quadratic time complexity:\n\n```python\n\
    \nmatch = re.search(r'^(\\+|-)?(\\d+|(\\d*\\.\\d*))?(E|e)?([-+])?(\\d+)?$', str)\
    \ \n```\nIt is not immediately obvious how to rewrite this regular expression\
    \ to avoid the problem. However, you can mitigate performance issues by limiting\
    \ the length to 1000 characters, which will always finish in a reasonable amount\
    \ of time.\n\n```python\n\nif len(str) > 1000:\n    raise ValueError(\"Input too\
    \ long\")\n\nmatch = re.search(r'^(\\+|-)?(\\d+|(\\d*\\.\\d*))?(E|e)?([-+])?(\\\
    d+)?$', str) \n```\n\n## References\n* OWASP: [Regular expression Denial of Service\

    # Inefficient regular expression
    Some regular expressions take a long time to match certain input strings to the point where the time it takes to match a string of length *n* is proportional to *n<sup>k</sup>* or even *2<sup>n</sup>*. Such regular expressions can negatively affect performance, or even allow a malicious user to perform a Denial of Service ("DoS") attack by crafting an expensive input string for the regular expression to match.

    The regular expression engine provided by Python uses a backtracking non-deterministic finite automata to implement regular expression matching. While this approach is space-efficient and allows supporting advanced features like capture groups, it is not time-efficient in general. The worst-case time complexity of such an automaton can be polynomial or even exponential, meaning that for strings of a certain shape, increasing the input length by ten characters may make the automaton about 1000 times slower.

    Typically, a regular expression is affected by this problem if it contains a repetition of the form `r*` or `r+` where the sub-expression `r` is ambiguous in the sense that it can match some string in multiple ways. More information about the precise circumstances can be found in the references.


    ## Recommendation
    Modify the regular expression to remove the ambiguity, or ensure that the strings matched with the regular expression are short enough that the time-complexity does not matter.


    ## Example
    Consider this regular expression:

    ```python

    ^_(__|.)+_$
    ```
    Its sub-expression `"(__|.)+?"` can match the string `"__"` either by the first alternative `"__"` to the left of the `"|"` operator, or by two repetitions of the second alternative `"."` to the right. Thus, a string consisting of an odd number of underscores followed by some other character will cause the regular expression engine to run for an exponential amount of time before rejecting the input.

    This problem can be avoided by rewriting the regular expression to remove the ambiguity between the two branches of the alternative inside the repetition:

    ```python

    ^_(__|[^_])+_$
    ```

    # Regular expression injection
    Constructing a regular expression with unsanitized user input is dangerous as a malicious user may be able to modify the meaning of the expression. In particular, such a user may be able to provide a regular expression fragment that takes exponential time in the worst case, and use that to perform a Denial of Service attack.


    ## Recommendation
    Before embedding user input into a regular expression, use a sanitization function such as `re.escape` to escape meta-characters that have a special meaning regarding regular expressions' syntax.


    ## Example
    The following examples are based on a simple Flask web server environment.

    The following example shows a HTTP request parameter that is used to construct a regular expression without sanitizing it first:


    ```python
    from flask import request, Flask
    import re


    @app.route("/direct")
    def direct():
        unsafe_pattern = request.args["pattern"]
        re.search(unsafe_pattern, "")


    @app.route("/compile")
    def compile():
        unsafe_pattern = request.args["pattern"]
        compiled_pattern = re.compile(unsafe_pattern)
        compiled_pattern.search("")

    ```
    Instead, the request parameter should be sanitized first, for example using the function `re.escape`. This ensures that the user cannot insert characters which have a special meaning in regular expressions.


    ```python
    from flask import request, Flask
    import re


    @app.route("/direct")
    def direct():
        unsafe_pattern = request.args['pattern']
        safe_pattern = re.escape(unsafe_pattern)
        re.search(safe_pattern, "")


    @app.route("/compile")
    def compile():
        unsafe_pattern = request.args['pattern']
        safe_pattern = re.escape(unsafe_pattern)
        compiled_pattern = re.compile(safe_pattern)
        compiled_pattern.search("")

    ```

    # XML internal entity expansion
    Parsing untrusted XML files with a weakly configured XML parser may be vulnerable to denial-of-service (DoS) attacks exploiting uncontrolled internal entity expansion.

    In XML, so-called *internal entities* are a mechanism for introducing an abbreviation for a piece of text or part of a document. When a parser that has been configured to expand entities encounters a reference to an internal entity, it replaces the entity by the data it represents. The replacement text may itself contain other entity references, which are expanded recursively. This means that entity expansion can increase document size dramatically.

    If untrusted XML is parsed with entity expansion enabled, a malicious attacker could submit a document that contains very deeply nested entity definitions, causing the parser to take a very long time or use large amounts of memory. This is sometimes called an *XML bomb* attack.


    ## Recommendation
    The safest way to prevent XML bomb attacks is to disable entity expansion when parsing untrusted data. Whether this can be done depends on the library being used. Note that some libraries, such as `lxml`, have measures enabled by default to prevent such DoS XML attacks, so unless you have explicitly set `huge_tree` to `True`, no further action is needed.

    We recommend using the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package, which has been created to prevent XML attacks (both XXE and XML bombs).


    ## Example
    The following example uses the `xml.etree` XML parser provided by the Python standard library to parse a string `xml_src`. That string is from an untrusted source, so this code is vulnerable to a DoS attack, since the `xml.etree` XML parser expands internal entities by default:


    ```python
    from flask import Flask, request
    import xml.etree.ElementTree as ET

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = ET.fromstring(xml_src)
        return ET.tostring(doc)

    ```
    It is not possible to guard against internal entity expansion with `xml.etree`, so to guard against these attacks, the following example uses the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package instead, which is not exposed to such internal entity expansion attacks.


    ```python
    from flask import Flask, request
    import defusedxml.ElementTree as ET

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = ET.fromstring(xml_src)
        return ET.tostring(doc)

    ```

    # Full server-side request forgery
    Directly incorporating user input into an HTTP request without validating the input can facilitate server-side request forgery (SSRF) attacks. In these attacks, the request may be changed, directed at a different server, or via a different protocol. This can allow the attacker to obtain sensitive information or perform actions with escalated privilege.

    We make a distinctions between how much of the URL an attacker can control:

    * **Full SSRF**: where the full URL can be controlled.
    * **Partial SSRF**: where only part of the URL can be controlled, such as the path component of a URL to a hardcoded domain.


    Partial control of a URL is often much harder to exploit. Therefore we have created a separate query for each of these.

    This query covers full SSRF, to find partial SSRF use the `py/partial-ssrf` query.


    ## Recommendation
    To guard against SSRF attacks you should avoid putting user-provided input directly into a request URL. On the application level, maintain a list of authorized URLs on the server and choose from that list based on the input provided. If that is not possible, one should verify the IP address for all user-controlled requests to ensure they are not private. This requires saving the verified IP address of each domain, then utilizing a custom HTTP adapter to ensure that future requests to that domain use the verified IP address. On the network level, you can segment the vulnerable application into its own LAN or block access to specific devices.


    ## Example
    The following example shows code vulnerable to a full SSRF attack, because it uses untrusted input (HTTP request parameter) directly to construct a URL. By using `evil.com#` as the `target` value, the requested URL will be `https://evil.com#.example.com/data/`. It also shows how to remedy the problem by using the user input select a known fixed string.


    ```python
    import requests
    from flask import Flask, request

    app = Flask(__name__)

    @app.route("/full_ssrf")
    def full_ssrf():
        target = request.args["target"]

        # BAD: user has full control of URL
        resp = requests.get("https://" + target + ".example.com/data/")

        # GOOD: `subdomain` is controlled by the server.
        subdomain = "europe" if target == "EU" else "world"
        resp = requests.get("https://" + subdomain + ".example.com/data/")

    ```

    ## Example
    The following example shows code vulnerable to a partial SSRF attack, because it uses untrusted input (HTTP request parameter) directly to construct a URL. By using `../transfer-funds-to/123?amount=456` as the `user_id` value, the requested URL will be `https://api.example.com/transfer-funds-to/123?amount=456`. It also shows how to remedy the problem by validating the input.


    ```python
    import requests
    from flask import Flask, request

    app = Flask(__name__)

    @app.route("/partial_ssrf")
    def partial_ssrf():
        user_id = request.args["user_id"]

        # BAD: user can fully control the path component of the URL
        resp = requests.get("https://api.example.com/user_info/" + user_id)

        if user_id.isalnum():
            # GOOD: user_id is restricted to be alpha-numeric, and cannot alter path component of URL
            resp = requests.get("https://api.example.com/user_info/" + user_id)

    ```

By using `../transfer-funds-to/123?amount=456` as the `user_id` value, the requested URL will be `https://api.example.com/transfer-funds-to/123?amount=456`. It also shows how to remedy the problem by validating the input.


    ```python
    import requests
    from flask import Flask, request

    app = Flask(__name__)

    @app.route("/partial_ssrf")
    def partial_ssrf():
        user_id = request.args["user_id"]

        # BAD: user can fully control the path component of the URL
        resp = requests.get("https://api.example.com/user_info/" + user_id)

        if user_id.isalnum():
            # GOOD: user_id is restricted to be alpha-numeric, and cannot alter path component of URL
            resp = requests.get("https://api.example.com/user_info/" + user_id)

    ```

    # NoSQL Injection
    Passing user-controlled sources into NoSQL queries can result in a NoSQL injection flaw. This tainted NoSQL query containing a user-controlled source can then execute a malicious query in a NoSQL database such as MongoDB. In order for the user-controlled source to taint the NoSQL query, the user-controller source must be converted into a Python object using something like `json.loads` or `xmltodict.parse`.

    Because a user-controlled source is passed into the query, the malicious user can have complete control over the query itself. When the tainted query is executed, the malicious user can commit malicious actions such as bypassing role restrictions or accessing and modifying restricted data in the NoSQL database.


    ## Recommendation
    NoSQL injections can be prevented by escaping user-input's special characters that are passed into the NoSQL query from the user-supplied source. Alternatively, using a sanitize library such as MongoSanitizer will ensure that user-supplied sources can not act as a malicious query.


    ## Example
    In the example below, the user-supplied source is passed to a MongoDB function that queries the MongoDB database.


    ```python
    from flask import Flask, request
    from flask_pymongo import PyMongo
    import json

    mongo = PyMongo(app)


    @app.route("/")
    def home_page():
        unsanitized_search = request.args['search']
        json_search = json.loads(unsanitized_search)

        result = mongo.db.user.find({'name': json_search})

    ```
    This can be fixed by using a sanitizer library like MongoSanitizer as shown in this annotated code version below.


    ```python
    from flask import Flask, request
    from flask_pymongo import PyMongo
    from mongosanitizer.sanitizer import sanitize
    import json

    mongo = PyMongo(app)


    @app.route("/")
    def home_page():
        unsafe_search = request.args['search']
        json_search = json.loads(unsafe_search)
        safe_search = sanitize(unsanitized_search)

        result = client.db.collection.find_one({'data': safe_search})

    ```

    # 'input' function used in Python 2
    In Python 2, a call to the `input()` function, `input(prompt)` is equivalent to `eval(raw_input(prompt))`. Evaluating user input without any checking can be a serious security flaw.


    ## Recommendation
    Get user input with `raw_input(prompt)` and then validate that input before evaluating. If the expected input is a number or string, then `ast.literal_eval()` can always be used safely.

    # Binding a socket to all network interfaces
    Sockets can be used to communicate with other machines on a network. You can use the (IP address, port) pair to define the access restrictions for the socket you create. When using the built-in Python `socket` module (for instance, when building a message sender service or an FTP server data transmitter), one has to bind the port to some interface. When you bind the port to all interfaces using `0.0.0.0` as the IP address, you essentially allow it to accept connections from any IPv4 address provided that it can get to the socket via routing. Binding to all interfaces is therefore associated with security risks.


    ## Recommendation
    Bind your service incoming traffic only to a dedicated interface. If you need to bind more than one interface using the built-in `socket` module, create multiple sockets (instead of binding to one socket to all interfaces).


    ## Example
    In this example, two sockets are insecure because they are bound to all interfaces; one through the `0.0.0.0` notation and another one through an empty string `''`.


    ```python
    import socket

    # binds to all interfaces, insecure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('0.0.0.0', 31137))

    # binds to all interfaces, insecure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('', 4040))

    # binds only to a dedicated interface, secure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('84.68.10.12', 8080))

    ```

    # Construction of a cookie using user-supplied input
    Constructing cookies from user input can allow an attacker to control a user's cookie. This may lead to a session fixation attack. Additionally, client code may not expect a cookie to contain attacker-controlled data, and fail to sanitize it for common vulnerabilities such as Cross Site Scripting (XSS). An attacker manipulating the raw cookie header may additionally be able to set cookie attributes such as `HttpOnly` to insecure values.


    ## Recommendation
    Do not use raw user input to construct cookies.


    ## Example
    In the following cases, a cookie is constructed for a Flask response using user input. The first uses `set_cookie`, and the second sets a cookie's raw value through the `set-cookie` header.


    ```python
    from flask import request, make_response


    @app.route("/1")
    def set_cookie():
        resp = make_response()
        resp.set_cookie(request.args["name"], # BAD: User input is used to set the cookie's name and value
                        value=request.args["name"])
        return resp


    @app.route("/2")
    def set_cookie_header():
        resp = make_response()
        resp.headers['Set-Cookie'] = f"{request.args['name']}={request.args['name']};" # BAD: User input is used to set the raw cookie header.
        return resp

    ```

    # Incomplete regular expression for hostnames
    Sanitizing untrusted URLs is a common technique for preventing attacks such as request forgeries and malicious redirections. Often, this is done by checking that the host of a URL is in a set of allowed hosts.

    If a regular expression implements such a check, it is easy to accidentally make the check too permissive by not escaping the `.` meta-characters appropriately. Even if the check is not used in a security-critical context, the incomplete check may still cause undesirable behaviors when it accidentally succeeds.


    ## Recommendation
    Escape all meta-characters appropriately when constructing regular expressions for security checks, and pay special attention to the `.` meta-character.


    ## Example
    The following example code checks that a URL redirection will reach the `example.com` domain, or one of its subdomains.


    ```python
    from flask import Flask, request, redirect
    import re

    app = Flask(__name__)

    UNSAFE_REGEX = re.compile("(www|beta).example.com/")
    SAFE_REGEX = re.compile(r"(www|beta)\.example\.com/")

    @app.route('/some/path/bad')
    def unsafe(request):
        target = request.args.get('target', '')
        if UNSAFE_REGEX.match(target):
            return redirect(target)

    @app.route('/some/path/good')
    def safe(request):
        target = request.args.get('target', '')
        if SAFE_REGEX.match(target):
            return redirect(target)

    ```
    The `unsafe` check is easy to bypass because the unescaped `.` allows for any character before `example.com`, effectively allowing the redirect to go to an attacker-controlled domain such as `wwwXexample.com`.

    The `safe` check closes this vulnerability by escaping the `.` so that URLs of the form `wwwXexample.com` are rejected.

    # Incomplete URL substring sanitization
    Sanitizing untrusted URLs is a common technique for preventing attacks such as request forgeries and malicious redirections. Usually, this is done by checking that the host of a URL is in a set of allowed hosts.

    However, treating the URL as a string and checking if one of the allowed hosts is a substring of the URL is very prone to errors. Malicious URLs can bypass such security checks by embedding one of the allowed hosts in an unexpected location.

    Even if the substring check is not used in a security-critical context, the incomplete check may still cause undesirable behaviors when the check succeeds accidentally.


    ## Recommendation
    Parse a URL before performing a check on its host value, and ensure that the check handles arbitrary subdomain sequences correctly.


    ## Example
    The following example code checks that a URL redirection will reach the `example.com` domain.


    ```python
    from flask import Flask, request, redirect
    from urllib.parse import urlparse

    app = Flask(__name__)

    # Not safe, as "evil-example.net/example.com" would be accepted

    @app.route('/some/path/bad1')
    def unsafe1(request):
        target = request.args.get('target', '')
        if "example.com" in target:
            return redirect(target)

    # Not safe, as "benign-looking-prefix-example.com" would be accepted

    @app.route('/some/path/bad2')
    def unsafe2(request):
        target = request.args.get('target', '')
        if target.endswith("example.com"):
            return redirect(target)



    #Simplest and safest approach is to use an allowlist

    @app.route('/some/path/good1')
    def safe1(request):
        allowlist = [
            "example.com/home",
            "example.com/login",
        ]
        target = request.args.get('target', '')
        if target in allowlist:
            return redirect(target)

    #More complex example allowing sub-domains.

    @app.route('/some/path/good2')
    def safe2(request):
        target = request.args.get('target', '')
        host = urlparse(target).hostname
        #Note the '.' preceding example.com
        if host and host.endswith(".example.com"):
            return redirect(target)


    ```
    The first two examples show unsafe checks that are easily bypassed. In `unsafe1` the attacker can simply add `example.com` anywhere in the url. For example, `http://evil-example.net/example.com`.

    In `unsafe2` the attacker must use a hostname ending in `example.com`, but that is easy to do. For example, `http://benign-looking-prefix-example.com`.

    The second two examples show safe checks. In `safe1`, an allowlist is used. Although fairly inflexible, this is easy to get right and is most likely to be safe.

    In `safe2`, `urlparse` is used to parse the URL, then the hostname is checked to make sure it ends with `.example.com`.

    # Overly permissive regular expression range
    It's easy to write a regular expression range that matches a wider range of characters than you intended. For example, `/[a-zA-z]/` matches all lowercase and all uppercase letters, as you would expect, but it also matches the characters: `` [ \ ] ^ _ ` ``.

    Another common problem is failing to escape the dash character in a regular expression. An unescaped dash is interpreted as part of a range. For example, in the character class `[a-zA-Z0-9%=.,-_]` the last character range matches the 55 characters between `,` and `_` (both included), which overlaps with the range `[0-9]` and is clearly not intended by the writer.


    ## Recommendation
    Avoid any confusion about which characters are included in the range by writing unambiguous regular expressions. Always check that character ranges match only the expected characters.


    ## Example
    The following example code is intended to check whether a string is a valid 6 digit hex color.

    ```python

    import re
    def is_valid_hex_color(color):
        return re.match(r'^#[0-9a-fA-f]{6}$', color) is not None

    ```
    However, the `A-f` range is overly large and matches every uppercase character. It would parse a "color" like `#XXYYZZ` as valid.

    The fix is to use an uppercase `A-F` range instead.

    ```python

    import re
    def is_valid_hex_color(color):
        return re.match(r'^#[0-9a-fA-F]{6}$', color) is not None

    ```

    # Uncontrolled data used in path expression
    Accessing files using paths constructed from user-controlled data can allow an attacker to access unexpected resources. This can result in sensitive information being revealed or deleted, or an attacker being able to influence behavior by modifying unexpected files.


    ## Recommendation
    Validate paths constructed from untrusted user input before using them to access files.

    The choice of validation depends on the use case.

    If you want to allow paths spanning multiple folders, a common strategy is to make sure that the constructed file path is contained within a safe root folder. First, normalize the path using `os.path.normpath` or `os.path.realpath` (make sure to use the latter if symlinks are a consideration) to remove any internal ".." segments and/or follow links. Then check that the normalized path starts with the root folder. Note that the normalization step is important, since otherwise even a path that starts with the root folder could be used to access files outside the root folder.

    More restrictive options include using a library function like `werkzeug.utils.secure_filename` to eliminate any special characters from the file path, or restricting the path to a known list of safe paths. These options are safe, but can only be used in particular circumstances.


    ## Example
    In the first example, a file name is read from an HTTP request and then used to access a file. However, a malicious user could enter a file name that is an absolute path, such as `"/etc/passwd"`.

    In the second example, it appears that the user is restricted to opening a file within the `"user"` home directory. However, a malicious user could enter a file name containing special characters. For example, the string `"../../../etc/passwd"` will result in the code reading the file located at `"/server/static/images/../../../etc/passwd"`, which is the system's password file. This file would then be sent back to the user, giving them access to all the system's passwords. Note that a user could also use an absolute path here, since the result of `os.path.join("/server/static/images/", "/etc/passwd")` is `"/etc/passwd"`.

    In the third example, the path used to access the file system is normalized *before* being checked against a known prefix. This ensures that regardless of the user input, the resulting path is safe.


    ```python
    import os.path
    from flask import Flask, request, abort

    app = Flask(__name__)

    @app.route("/user_picture1")
    def user_picture1():
        filename = request.args.get('p')
        # BAD: This could read any file on the file system
        data = open(filename, 'rb').read()
        return data

    @app.route("/user_picture2")
    def user_picture2():
        base_path = '/server/static/images'
        filename = request.args.get('p')
        # BAD: This could still read any file on the file system
        data = open(os.path.join(base_path, filename), 'rb').read()
        return data

    @app.route("/user_picture3")
    def user_picture3():
        base_path = '/server/static/images'
        filename = request.args.get('p')
        #GOOD -- Verify with normalised version of path
        fullpath = os.path.normpath(os.path.join(base_path, filename))
        if not fullpath.startswith(base_path):
            raise Exception("not allowed")
        data = open(fullpath, 'rb').read()
        return data

    ```

    # Arbitrary file write during tarfile extraction
    Extracting files from a malicious tar archive without validating that the destination file path is within the destination directory can cause files outside the destination directory to be overwritten, due to the possible presence of directory traversal elements (`..`) in archive paths.

    Tar archives contain archive entries representing each file in the archive. These entries include a file path for the entry, but these file paths are not restricted and may contain unexpected special elements such as the directory traversal element (`..`). If these file paths are used to determine an output file to write the contents of the archive item to, then the file may be written to an unexpected location. This can result in sensitive information being revealed or deleted, or an attacker being able to influence behavior by modifying unexpected files.

    For example, if a tar archive contains a file entry `..\sneaky-file`, and the tar archive is extracted to the directory `c:\output`, then naively combining the paths would result in an output file path of `c:\output\..\sneaky-file`, which would cause the file to be written to `c:\sneaky-file`.


    ## Recommendation
    Ensure that output paths constructed from tar archive entries are validated to prevent writing files to unexpected locations.

    The recommended way of writing an output file from a tar archive entry is to check that `".."` does not occur in the path.


    ## Example
    In this example an archive is extracted without validating file paths. If `archive.tar` contained relative paths (for instance, if it were created by something like `tar -cf archive.tar ../file.txt`) then executing this code could write to locations outside the destination directory.


    ```python
    import sys
    import tarfile

    with tarfile.open(sys.argv[1]) as tar:
        #BAD : This could write any file on the filesystem.
        for entry in tar:
            tar.extract(entry, "/tmp/unpack/")

    ```
    To fix this vulnerability, we need to check that the path does not contain any `".."` elements in it.


    ```python
    import sys
    import tarfile
    import os.path

    with tarfile.open(sys.argv[1]) as tar:
        for entry in tar:
            #GOOD: Check that entry is safe
            if os.path.isabs(entry.name) or ".." in entry.name:
                raise ValueError("Illegal tar archive entry")
            tar.extract(entry, "/tmp/unpack/")

    ```

    # Uncontrolled command line
    Code that passes user input directly to `exec`, `eval`, or some other library routine that executes a command, allows the user to execute malicious code.


    ## Recommendation
    If possible, use hard-coded string literals to specify the command to run or the library to load. Instead of passing the user input directly to the process or library function, examine the user input and then choose among hard-coded string literals.

    If the applicable libraries or commands cannot be determined at compile time, then add code to verify that the user input string is safe before using it.


    ## Example
    The following example shows two functions. The first is unsafe as it takes a shell script that can be changed by a user, and passes it straight to `subprocess.call()` without examining it first. The second is safe as it selects the command from a predefined allowlist.


    ```python

    urlpatterns = [
        # Route to command_execution
        url(r'^command-ex1$', command_execution_unsafe, name='command-execution-unsafe'),
        url(r'^command-ex2$', command_execution_safe, name='command-execution-safe')
    ]

    COMMANDS = {
        "list" :"ls",
        "stat" : "stat"
    }

    def command_execution_unsafe(request):
        if request.method == 'POST':
            action = request.POST.get('action', '')
            #BAD -- No sanitizing of input
            subprocess.call(["application", action])

    def command_execution_safe(request):
        if request.method == 'POST':
            action = request.POST.get('action', '')
            #GOOD -- Use an allowlist
            subprocess.call(["application", COMMANDS[action]])

    # Jinja2 templating with autoescape=False
    Cross-site scripting (XSS) attacks can occur if untrusted input is not escaped. This applies to templates as well as code. The `jinja2` templates may be vulnerable to XSS if the environment has `autoescape` set to `False`. Unfortunately, `jinja2` sets `autoescape` to `False` by default. Explicitly setting `autoescape` to `True` when creating an `Environment` object will prevent this.


    ## Recommendation
    Avoid setting jinja2 autoescape to False. Jinja2 provides the function `select_autoescape` to make sure that the correct auto-escaping is chosen. For example, it can be used when creating an environment `Environment(autoescape=select_autoescape(['html', 'xml'])`


    ## Example
    The following example is a minimal Flask app which shows a safe and an unsafe way to render the given name back to the page. The first view is unsafe as `first_name` is not escaped, leaving the page vulnerable to cross-site scripting attacks. The second view is safe as `first_name` is escaped, so it is not vulnerable to cross-site scripting attacks.


    ```python
    from flask import Flask, request, make_response, escape
    from jinja2 import Environment, select_autoescape, FileSystemLoader

    app = Flask(__name__)
    loader = FileSystemLoader( searchpath="templates/" )

    unsafe_env = Environment(loader=loader)
    safe1_env = Environment(loader=loader, autoescape=True)
    safe2_env = Environment(loader=loader, autoescape=select_autoescape())

    def render_response_from_env(env):
        name = request.args.get('name', '')
        template = env.get_template('template.html')
        return make_response(template.render(name=name))

    @app.route('/unsafe')
    def unsafe():
        return render_response_from_env(unsafe_env)

    @app.route('/safe1')
    def safe1():
        return render_response_from_env(safe1_env)

    @app.route('/safe2')
    def safe2():
        return render_response_from_env(safe2_env)


    ```

    # Reflected server-side cross-site scripting
    Directly writing user input (for example, an HTTP request parameter) to a webpage without properly sanitizing the input first, allows for a cross-site scripting vulnerability.


    ## Recommendation
    To guard against cross-site scripting, consider escaping the input before writing user input to the page. The standard library provides escaping functions: `html.escape()` for Python 3.2 upwards or `cgi.escape()` older versions of Python. Most frameworks also provide their own escaping functions, for example `flask.escape()`.


    ## Example
    The following example is a minimal flask app which shows a safe and unsafe way to render the given name back to the page. The first view is unsafe as `first_name` is not escaped, leaving the page vulnerable to cross-site scripting attacks. The second view is safe as `first_name` is escaped, so it is not vulnerable to cross-site scripting attacks.


    ```python
    from flask import Flask, request, make_response, escape

    app = Flask(__name__)

    @app.route('/unsafe')
    def unsafe():
        first_name = request.args.get('name', '')
        return make_response("Your name is " + first_name)

    @app.route('/safe')
    def safe():
        first_name = request.args.get('name', '')
        return make_response("Your name is " + escape(first_name))

    # SQL query built from user-controlled sources
    If a database query (such as a SQL or NoSQL query) is built from user-provided data without sufficient sanitization, a user may be able to run malicious database queries.

    This also includes using the `TextClause` class in the `[SQLAlchemy](https://pypi.org/project/SQLAlchemy/)` PyPI package, which is used to represent a literal SQL fragment and is inserted directly into the final SQL when used in a query built using the ORM.


    ## Recommendation
    Most database connector libraries offer a way of safely embedding untrusted data into a query by means of query parameters or prepared statements.


    ## Example
    In the following snippet, a user is fetched from the database using three different queries.

    In the first case, the query string is built by directly using string formatting from a user-supplied request parameter. The parameter may include quote characters, so this code is vulnerable to a SQL injection attack.

    In the second case, the user-supplied request attribute is passed to the database using query parameters. The database connector library will take care of escaping and inserting quotes as needed.

    In the third case, the placeholder in the SQL string has been manually quoted. Since most databaseconnector libraries will insert their own quotes, doing so yourself will make the code vulnerable to SQL injection attacks. In this example, if `username` was `; DROP ALL TABLES -- `, the final SQL query would be `SELECT * FROM users WHERE username = ''; DROP ALL TABLES -- ''`


    ```python
    from django.conf.urls import url
    from django.db import connection


    def show_user(request, username):
        with connection.cursor() as cursor:
            # BAD -- Using string formatting
            cursor.execute("SELECT * FROM users WHERE username = '%s'" % username)
            user = cursor.fetchone()

            # GOOD -- Using parameters
            cursor.execute("SELECT * FROM users WHERE username = %s", username)
            user = cursor.fetchone()

            # BAD -- Manually quoting placeholder (%s)
            cursor.execute("SELECT * FROM users WHERE username = '%s'", username)
            user = cursor.fetchone()

    urlpatterns = [url(r'^users/(?P<username>[^/]+)$', show_user)]

    ```

    # LDAP query built from user-controlled sources
    If an LDAP query or DN is built using string concatenation or string formatting, and the components of the concatenation include user input without any proper sanitization, a user is likely to be able to run malicious LDAP queries.


    ## Recommendation
    If user input must be included in an LDAP query or DN, it should be escaped to avoid a malicious user providing special characters that change the meaning of the query. In Python2, user input should be escaped with `ldap.dn.escape_dn_chars` or `ldap.filter.escape_filter_chars`, while in Python3, user input should be escaped with `ldap3.utils.dn.escape_rdn` or `ldap3.utils.conv.escape_filter_chars` depending on the component tainted by the user. A good practice is to escape filter characters that could change the meaning of the query (https://tools.ietf.org/search/rfc4515\#section-3).


    ## Example
    In the following examples, the code accepts both `username` and `dc` from the user, which it then uses to build a LDAP query and DN.

    The first and the second example uses the unsanitized user input directly in the search filter and DN for the LDAP query. A malicious user could provide special characters to change the meaning of these components, and search for a completely different set of values.


    ```python
    from flask import request, Flask
    import ldap


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        dn = "dc={}".format(unsafe_dc)
        search_filter = "(user={})".format(unsafe_filter)

        ldap_connection = ldap.initialize("ldap://127.0.0.1")
        user = ldap_connection.search_s(
            dn, ldap.SCOPE_SUBTREE, search_filter)

    ```

    ```python
    from flask import request, Flask
    import ldap3


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        dn = "dc={}".format(unsafe_dc)
        search_filter = "(user={})".format(unsafe_filter)

        srv = ldap3.Server('ldap://127.0.0.1')
        conn = ldap3.Connection(srv, user=dn, auto_bind=True)
        conn.search(dn, search_filter)

    ```
    In the third and fourth example, the input provided by the user is sanitized before it is included in the search filter or DN. This ensures the meaning of the query cannot be changed by a malicious user.


    ```python
    from flask import request, Flask
    import ldap
    import ldap.filter
    import ldap.dn


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        safe_dc = ldap.dn.escape_dn_chars(unsafe_dc)
        safe_filter = ldap.filter.escape_filter_chars(unsafe_filter)

        dn = "dc={}".format(safe_dc)
        search_filter = "(user={})".format(safe_filter)

        ldap_connection = ldap.initialize("ldap://127.0.0.1")
        user = ldap_connection.search_s(
            dn, ldap.SCOPE_SUBTREE, search_filter)

    ```

    ```python
    from flask import request, Flask
    import ldap3
    from ldap3.utils.dn import escape_rdn
    from ldap3.utils.conv import escape_filter_chars


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        safe_dc = escape_rdn(unsafe_dc)
        safe_filter = escape_filter_chars(unsafe_filter)

        dn = "dc={}".format(safe_dc)
        search_filter = "(user={})".format(safe_filter)

        srv = ldap3.Server('ldap://127.0.0.1')
        conn = ldap3.Connection(srv, user=dn, auto_bind=True)
        conn.search(dn, search_filter)

    # Code injection
    Directly evaluating user input (for example, an HTTP request parameter) as code without properly sanitizing the input first allows an attacker arbitrary code execution. This can occur when user input is passed to code that interprets it as an expression to be evaluated, such as `eval` or `exec`.


    ## Recommendation
    Avoid including user input in any expression that may be dynamically evaluated. If user input must be included, use context-specific escaping before including it. It is important that the correct escaping is used for the type of evaluation that will occur.


    ## Example
    The following example shows two functions setting a name from a request. The first function uses `exec` to execute the `setname` function. This is dangerous as it can allow a malicious user to execute arbitrary code on the server. For example, the user could supply the value `"' + subprocess.call('rm -rf') + '"` to destroy the server's file system. The second function calls the `setname` function directly and is thus safe.


    ```python

    urlpatterns = [
        # Route to code_execution
        url(r'^code-ex1$', code_execution_bad, name='code-execution-bad'),
        url(r'^code-ex2$', code_execution_good, name='code-execution-good')
    ]

    def code_execution(request):
        if request.method == 'POST':
            first_name = base64.decodestring(request.POST.get('first_name', ''))
            #BAD -- Allow user to define code to be run.
            exec("setname('%s')" % first_name)

    def code_execution(request):
        if request.method == 'POST':
            first_name = base64.decodestring(request.POST.get('first_name', ''))
            #GOOD --Call code directly
            setname(first_name)

    ```

  queryHelp: "# Bad HTML filtering regexp\nIt is possible to match some single HTML\
    \ tags using regular expressions (parsing general HTML using regular expressions\
    \ is impossible). However, if the regular expression is not written well it might\
    \ be possible to circumvent it, which can lead to cross-site scripting or other\
    \ security issues.\n\nSome of these mistakes are caused by browsers having very\
    \ forgiving HTML parsers, and will often render invalid HTML containing syntax\
    \ errors. Regular expressions that attempt to match HTML should also recognize\
    \ tags containing such syntax errors.\n\n\n## Recommendation\nUse a well-tested\
    \ sanitization or parser library if at all possible. These libraries are much\
    \ more likely to handle corner cases correctly than a custom implementation.\n\
    \n\n## Example\nThe following example attempts to filters out all `<script>` tags.\n\
    \n\n```python\nimport re\n\ndef filterScriptTags(content): \n    oldContent =\
    \ \"\"\n    while oldContent != content:\n        oldContent = content\n     \
    \   content = re.sub(r'<script.*?>.*?</script>', '', content, flags= re.DOTALL\
    \ | re.IGNORECASE)\n    return content\n```\nThe above sanitizer does not filter\
    \ out all `<script>` tags. Browsers will not only accept `</script>` as script\
    \ end tags, but also tags such as `</script foo=\"bar\">` even though it is a\
    \ parser error. This means that an attack string such as `<script>alert(1)</script\
    \ foo=\"bar\">` will not be filtered by the function, and `alert(1)` will be executed\
    \ by a browser if the string is rendered as HTML.\n\nOther corner cases include\
    \ that HTML comments can end with `--!>`, and that HTML tag names can contain\
    \ upper case characters.\n\n\n## References\n* Securitum: [The Curious Case of\

    # Log Injection
    If unsanitized user input is written to a log entry, a malicious user may be able to forge new log entries.

    Forgery can occur if a user provides some input with characters that are interpreted when the log output is displayed. If the log is displayed as a plain text file, then new line characters can be used by a malicious user to create the appearance of multiple log entries. If the log is displayed as HTML, then arbitrary HTML may be included to spoof log entries.


    ## Recommendation
    User input should be suitably sanitized before it is logged.

    If the log entries are plain text then line breaks should be removed from user input, using for example `replace(old, new)` or similar. Care should also be taken that user input is clearly marked in log entries, and that a malicious user cannot cause confusion in other ways.

    For log entries that will be displayed in HTML, user input should be HTML encoded before being logged, to prevent forgery and other forms of HTML injection.


    ## Example
    In the example, the name provided by the user is recorded using the log output function (`logging.info` or `app.logger.info`, etc.). In these four cases, the name provided by the user is not provided The processing is recorded. If a malicious user provides `Guest%0D%0AUser name: Admin` as a parameter, the log entry will be divided into two lines, the first line is `User name: Guest` code&gt;, the second line is `User name: Admin`.

    @app.route('/bad1')
    def bad1():
        name = request.args.get('name')
        app.logger.info('User name: ' + name) # Bad
        return 'bad1'

    @app.route('/bad2')
    def bad2():

    def bad3():

        handler = logging.FileHandler('log')
        app.logger.addHandler(handler)
        app.run()

    ```
    In a good example, the program uses the `replace` function to provide parameter processing to the user, and replace `\r\n` and `\n` with empty characters. To a certain extent, the occurrence of log injection vulnerabilities is reduced.

    # Information exposure through an exception
    Software developers often add stack traces to error messages, as a debugging aid. Whenever that error message occurs for an end user, the developer can use the stack trace to help identify how to fix the problem. In particular, stack traces can tell the developer more about the sequence of events that led to a failure, as opposed to merely the final state of the software when the error occurred.

    Unfortunately, the same information can be useful to an attacker. The sequence of class names in a stack trace can reveal the structure of the application as well as any internal components it relies on. Furthermore, the error message at the top of a stack trace can include information such as server-side file names and SQL code that the application relies on, allowing an attacker to fine-tune a subsequent injection attack.


    ## Recommendation
    Send the user a more generic error message that reveals less information. Either suppress the stack trace entirely, or log it only on the server.


    ## Example
    In the following example, an exception is handled in two different ways. In the first version, labeled BAD, the exception is sent back to the remote user by returning it from the function. As such, the user is able to see a detailed stack trace, which may contain sensitive information. In the second version, the error message is logged only on the server, and a generic error message is displayed to the user. That way, the developers can still access and use the error log, but remote users will not see the information.


    ```python
    from flask import Flask
    app = Flask(__name__)


    import traceback

    def do_computation():
        raise Exception("Secret info")

    # BAD
    @app.route('/bad')
    def server_bad():
        try:
            do_computation()
        except Exception as e:
            return traceback.format_exc()

    # GOOD
    @app.route('/good')
    def server_good():
        try:
            do_computation()
        except Exception as e:
            log(traceback.format_exc())
            return "An internal error has occurred!"

    ```

    # PAM authorization bypass due to incorrect usage
    Using only a call to `pam_authenticate` to check the validity of a login can lead to authorization bypass vulnerabilities.

    A `pam_authenticate` only verifies the credentials of a user. It does not check if a user has an appropriate authorization to actually login. This means a user with an expired login or a password can still access the system.


    ## Recommendation
    A call to `pam_authenticate` should be followed by a call to `pam_acct_mgmt` to check if a user is allowed to login.


    ## Example
    In the following example, the code only checks the credentials of a user. Hence, in this case, a user with expired credentials can still login. This can be verified by creating a new user account, expiring it with ``` chage -E0 `username`  ``` and then trying to log in.


    ```python
    libpam                    = CDLL(find_library("pam"))

    pam_authenticate          = libpam.pam_authenticate
    pam_authenticate.restype  = c_int
    pam_authenticate.argtypes = [PamHandle, c_int]

    def authenticate(username, password, service='login'):
        def my_conv(n_messages, messages, p_response, app_data):
            """
            Simple conversation function that responds to any prompt where the echo is off with the supplied password
            """
            ...

        handle = PamHandle()
        conv   = PamConv(my_conv, 0)
        retval = pam_start(service, username, byref(conv), byref(handle))

        retval = pam_authenticate(handle, 0)
        return retval == 0

    ```
    This can be avoided by calling `pam_acct_mgmt` call to verify access as has been done in the snippet shown below.


    ```python
    libpam                    = CDLL(find_library("pam"))

    pam_authenticate          = libpam.pam_authenticate
    pam_authenticate.restype  = c_int
    pam_authenticate.argtypes = [PamHandle, c_int]

    pam_acct_mgmt          = libpam.pam_acct_mgmt
    pam_acct_mgmt.restype  = c_int
    pam_acct_mgmt.argtypes = [PamHandle, c_int]

            """
            ...

        handle = PamHandle()
        conv   = PamConv(my_conv, 0)
        retval = pam_start(service, username, byref(conv), byref(handle))

        retval = pam_authenticate(handle, 0)
        if retval == 0:
            retval = pam_acct_mgmt(handle, 0)
        return retval == 0

    # Accepting unknown SSH host keys when using Paramiko
    In the Secure Shell (SSH) protocol, host keys are used to verify the identity of remote hosts. Accepting unknown host keys may leave the connection open to man-in-the-middle attacks.


    ## Recommendation
    Do not accept unknown host keys. In particular, do not set the default missing host key policy for the Paramiko library to either `AutoAddPolicy` or `WarningPolicy`. Both of these policies continue even when the host key is unknown. The default setting of `RejectPolicy` is secure because it throws an exception when it encounters an unknown host key.


    ## Example
    The following example shows two ways of opening an SSH connection to `example.com`. The first function sets the missing host key policy to `AutoAddPolicy`. If the host key verification fails, the client will continue to interact with the server, even though the connection may be compromised. The second function sets the host key policy to `RejectPolicy`, and will throw an exception if the host key verification fails.


    ```python
    from paramiko.client import SSHClient, AutoAddPolicy, RejectPolicy

    def unsafe_connect():
        client = SSHClient()
        client.set_missing_host_key_policy(AutoAddPolicy)
        client.connect("example.com")

        # ... interaction with server

        client.close()

    def safe_connect():
        client = SSHClient()
        client.set_missing_host_key_policy(RejectPolicy)
        client.connect("example.com")

        # ... interaction with server

        client.close()

    ```

    # Request without certificate validation
    Encryption is key to the security of most, if not all, online communication. Using Transport Layer Security (TLS) can ensure that communication cannot be interrupted by an interloper. For this reason, it is unwise to disable the verification that TLS provides. Functions in the `requests` module provide verification by default, and it is only when explicitly turned off using `verify=False` that no verification occurs.


    ## Recommendation
    Never use `verify=False` when making a request.


    ## Example
    The example shows two unsafe calls to [semmle.com](https://semmle.com), followed by various safe alternatives.


    ```python
    import requests

    #Unsafe requests

    requests.get('https://semmle.com', verify=False) # UNSAFE
    requests.get('https://semmle.com', verify=0) # UNSAFE

    #Various safe options

    requests.get('https://semmle.com', verify=True) # Explicitly safe
    requests.get('https://semmle.com', verify="/path/to/cert/")
    requests.get('https://semmle.com') # The default is to verify.

    #Wrapper to ensure safety

    def make_safe_request(url, verify_cert):
        if not verify_cert:
            raise Exception("Trying to make unsafe request")
        return requests.get(url, verify_cert)

    # Clear-text logging of sensitive information
    If sensitive data is written to a log entry it could be exposed to an attacker who gains access to the logs.

    Potential attackers can obtain sensitive user data when the log output is displayed. Additionally that data may expose system information such as full path names, system information, and sometimes usernames and passwords.


    ## Recommendation
    Sensitive data should not be logged.


    ## Example
    In the example the entire process environment is logged using \`print\`. Regular users of the production deployed application should not have access to this much information about the environment configuration.


    ```python
    # BAD: Logging cleartext sensitive data
    import os
    print(f"[INFO] Environment: {os.environ}")
    ```
    In the second example the data that is logged is not sensitive.


    ```python
    not_sensitive_data = {'a': 1, 'b': 2}
    # GOOD: it is fine to log data that is not sensitive
    print(f"[INFO] Some object contains: {not_sensitive_data}")
    ```

    # Clear-text storage of sensitive information
    Sensitive information that is stored unencrypted is accessible to an attacker who gains access to the storage. This is particularly important for cookies, which are stored on the machine of the end-user.


    ## Recommendation
    Ensure that sensitive information is always encrypted before being stored. If possible, avoid placing sensitive information in cookies altogether. Instead, prefer storing, in the cookie, a key that can be used to look up the sensitive information.

    In general, decrypt sensitive information only at the point where it is necessary for it to be used in cleartext.

    Be aware that external processes often store the `standard out` and `standard error` streams of the application, causing logged sensitive information to be stored as well.


    ## Example
    The following example code stores user credentials (in this case, their password) in a cookie in plain text:


    ```python
    from flask import Flask, make_response, request

    app = Flask("Leak password")

    @app.route('/')
    def index():
        password = request.args.get("password")
        resp = make_response(render_template(...))
        resp.set_cookie("password", password)
        return resp

    ```
    Instead, the credentials should be encrypted, for instance by using the `cryptography` module, or not stored at all.

    # Use of weak cryptographic key
    Modern encryption relies on it being computationally infeasible to break the cipher and decode a message without the key. As computational power increases, the ability to break ciphers grows and keys need to become larger.

    The three main asymmetric key algorithms currently in use are Rivest–Shamir–Adleman (RSA) cryptography, Digital Signature Algorithm (DSA), and Elliptic-curve cryptography (ECC). With current technology, key sizes of 2048 bits for RSA and DSA, or 256 bits for ECC, are regarded as unbreakable.


    ## Recommendation
    Increase the key size to the recommended amount or larger. For RSA or DSA this is at least 2048 bits, for ECC this is at least 256 bits.

    # Use of a broken or weak cryptographic algorithm
    Using broken or weak cryptographic algorithms may compromise security guarantees such as confidentiality, integrity, and authenticity.

    Many cryptographic algorithms are known to be weak or flawed. The security guarantees of a system often rely on the underlying cryptography, so using a weak algorithm can have severe consequences. For example:

    * If a weak encryption algorithm is used, an attacker may be able to decrypt sensitive data.
    * If a weak algorithm is used for digital signatures, an attacker may be able to forge signatures and impersonate legitimate users.
    This query alerts on any use of a weak cryptographic algorithm that is not a hashing algorithm. Use of broken or weak cryptographic hash functions are handled by the `py/weak-sensitive-data-hashing` query.


    ## Recommendation
    Ensure that you use a strong, modern cryptographic algorithm, such as AES-128 or RSA-2048.


    ## Example
    The following code uses the `pycryptodome` library to encrypt some secret data. When you create a cipher using `pycryptodome` you must specify the encryption algorithm to use. The first example uses DES, which is an older algorithm that is now considered weak. The second example uses AES, which is a stronger modern algorithm.


    ```python
    from Crypto.Cipher import DES, AES

    cipher = DES.new(SECRET_KEY)

    def send_encrypted(channel, message):
        channel.send(cipher.encrypt(message)) # BAD: weak encryption


    cipher = AES.new(SECRET_KEY)

    def send_encrypted(channel, message):
        channel.send(cipher.encrypt(message)) # GOOD: strong encryption


    ```
    NOTICE: the original `[pycrypto](https://pypi.org/project/pycrypto/)` PyPI package that provided the `Crypto` module is not longer actively maintained, so you should use the `[pycryptodome](https://pypi.org/project/pycryptodome/)` PyPI package instead (which has a compatible API).

    # Default version of SSL/TLS may be insecure
    The `ssl.wrap_socket` function defaults to an insecure version of SSL/TLS when no specific protocol version is specified. This may leave the connection vulnerable to attack.


    ## Recommendation
    Ensure that a modern, strong protocol is used. All versions of SSL, and TLS 1.0 and 1.1 are known to be vulnerable to attacks. Using TLS 1.2 or above is strongly recommended. If no explicit `ssl_version` is specified, the default `PROTOCOL_TLS` is chosen. This protocol is insecure because it allows TLS 1.0 and TLS 1.1 and so should not be used.


    ## Example
    The following code shows two different ways of setting up a connection using SSL or TLS. They are both potentially insecure because the default version is used.


    ```python
    import ssl
    import socket

    # Using the deprecated ssl.wrap_socket method
    ssl.wrap_socket(socket.socket())

    # Using SSLContext
    context = ssl.SSLContext()

    ```
    Both of the cases above should be updated to use a secure protocol instead, for instance by specifying `ssl_version=PROTOCOL_TLSv1_2` as a keyword argument.

    The latter example can also be made secure by modifying the created context before it is used to create a connection. Therefore it will not be flagged by this query. However, if a connection is created before the context has been secured (for example, by setting the value of `minimum_version`), then the code should be flagged by the query `py/insecure-protocol`.

    Note that `ssl.wrap_socket` has been deprecated in Python 3.7. The recommended alternatives are:

    * `ssl.SSLContext` - supported in Python 2.7.9, 3.2, and later versions
    * `ssl.create_default_context` - a convenience function, supported in Python 3.4 and later versions.
    Even when you use these alternatives, you should ensure that a safe protocol is used. The following code illustrates how to use flags (available since Python 3.2) or the \`minimum_version\` field (favored since Python 3.7) to restrict the protocols accepted when creating a connection.


    ```python
    import ssl

    # Using flags to restrict the protocol
    context = ssl.SSLContext()
    context.options |= ssl.OP_NO_TLSv1 | ssl.OP_NO_TLSv1_1

    # Declaring a minimum version to restrict the protocol
    context = ssl.create_default_context()
    context.minimum_version = ssl.TLSVersion.TLSv1_2

    ```

    # Use of a broken or weak cryptographic hashing algorithm on sensitive data
    Using a broken or weak cryptographic hash function can leave data vulnerable, and should not be used in security related code.

    A strong cryptographic hash function should be resistant to:

    * pre-image attacks: if you know a hash value `h(x)`, you should not be able to easily find the input `x`.
    * collision attacks: if you know a hash value `h(x)`, you should not be able to easily find a different input `y` with the same hash value `h(x) = h(y)`.
    In cases with a limited input space, such as for passwords, the hash function also needs to be computationally expensive to be resistant to brute-force attacks. Passwords should also have an unique salt applied before hashing, but that is not considered by this query.

    As an example, both MD5 and SHA-1 are known to be vulnerable to collision attacks.

    Since it's OK to use a weak cryptographic hash function in a non-security context, this query only alerts when these are used to hash sensitive data (such as passwords, certificates, usernames).

    Use of broken or weak cryptographic algorithms that are not hashing algorithms, is handled by the `py/weak-cryptographic-algorithm` query.


    ## Recommendation
    Ensure that you use a strong, modern cryptographic hash function:

    * such as Argon2, scrypt, bcrypt, or PBKDF2 for passwords and other data with limited input space.
    * such as SHA-2, or SHA-3 in other cases.

    ## Example
    The following example shows two functions for checking whether the hash of a certificate matches a known value -- to prevent tampering. The first function uses MD5 that is known to be vulnerable to collision attacks. The second function uses SHA-256 that is a strong cryptographic hashing function.


    ```python
    import hashlib

    def certificate_matches_known_hash_bad(certificate, known_hash):
        hash = hashlib.md5(certificate).hexdigest() # BAD
        return hash == known_hash

    def certificate_matches_known_hash_good(certificate, known_hash):
        hash = hashlib.sha256(certificate).hexdigest() # GOOD
        return hash == known_hash

    ```

    ## Example
    The following example shows two functions for hashing passwords. The first function uses SHA-256 to hash passwords. Although SHA-256 is a strong cryptographic hash function, it is not suitable for password hashing since it is not computationally expensive.


    ```python
    import hashlib

    def get_password_hash(password: str, salt: str):
        return hashlib.sha256(password + salt).hexdigest() # BAD

    ```
    The second function uses Argon2 (through the `argon2-cffi` PyPI package), which is a strong password hashing algorithm (and includes a per-password salt by default).


    ```python
    from argon2 import PasswordHasher

    def get_initial_hash(password: str):
        ph = PasswordHasher()
        return ph.hash(password) # GOOD

    def check_password(password: str, known_hash):
        ph = PasswordHasher()
        return ph.verify(known_hash, password) # GOOD

    ```

    # CSRF protection weakened or disabled
    Cross-site request forgery (CSRF) is a type of vulnerability in which an attacker is able to force a user to carry out an action that the user did not intend.

    The attacker tricks an authenticated user into submitting a request to the web application. Typically this request will result in a state change on the server, such as changing the user's password. The request can be initiated when the user visits a site controlled by the attacker. If the web application relies only on cookies for authentication, or on other credentials that are automatically included in the request, then this request will appear as legitimate to the server.

    A common countermeasure for CSRF is to generate a unique token to be included in the HTML sent from the server to a user. This token can be used as a hidden field to be sent back with requests to the server, where the server can then check that the token is valid and associated with the relevant user session.


    ## Recommendation
    In many web frameworks, CSRF protection is enabled by default. In these cases, using the default configuration is sufficient to guard against most CSRF attacks.


    ## Example
    The following example shows a case where CSRF protection is disabled by overriding the default middleware stack and not including the one protecting against CSRF.


    ```python
    MIDDLEWARE = [
        'django.middleware.security.SecurityMiddleware',
        'django.contrib.sessions.middleware.SessionMiddleware',
        'django.middleware.common.CommonMiddleware',
        # 'django.middleware.csrf.CsrfViewMiddleware',
        'django.contrib.auth.middleware.AuthenticationMiddleware',
        'django.contrib.messages.middleware.MessageMiddleware',
        'django.middleware.clickjacking.XFrameOptionsMiddleware',
    ]

    ```
    The protecting middleware was probably commented out during a testing phase, when server-side token generation was not set up. Simply commenting it back in will enable CSRF protection.

    # Insecure temporary file
    Functions that create temporary file names (such as `tempfile.mktemp` and `os.tempnam`) are fundamentally insecure, as they do not ensure exclusive access to a file with the temporary name they return. The file name returned by these functions is guaranteed to be unique on creation but the file must be opened in a separate operation. There is no guarantee that the creation and open operations will happen atomically. This provides an opportunity for an attacker to interfere with the file before it is opened.

    Note that `mktemp` has been deprecated since Python 2.3.


    ## Recommendation
    Replace the use of `mktemp` with some of the more secure functions in the `tempfile` module, such as `TemporaryFile`. If the file is intended to be accessed from other processes, consider using the `NamedTemporaryFile` function.


    ## Example
    The following piece of code opens a temporary file and writes a set of results to it. Because the file name is created using `mktemp`, another process may access this file before it is opened using `open`.


    ```python
    from tempfile import mktemp

    def write_results(results):
        filename = mktemp()
        with open(filename, "w+") as f:
            f.write(results)
        print("Results written to", filename)

    ```
    By changing the code to use `NamedTemporaryFile` instead, the file is opened immediately.


    ```python
    from tempfile import NamedTemporaryFile

    def write_results(results):
        with NamedTemporaryFile(mode="w+", delete=False) as f:
            f.write(results)
        print("Results written to", f.name)

    # Deserialization of user-controlled data
    Deserializing untrusted data using any deserialization framework that allows the construction of arbitrary serializable objects is easily exploitable and in many cases allows an attacker to execute arbitrary code. Even before a deserialized object is returned to the caller of a deserialization method a lot of code may have been executed, including static initializers, constructors, and finalizers. Automatic deserialization of fields means that an attacker may craft a nested combination of objects on which the executed initialization code may have unforeseen effects, such as the execution of arbitrary code.

    There are many different serialization frameworks. This query currently supports Pickle, Marshal and Yaml.


    ## Recommendation
    Avoid deserialization of untrusted data if at all possible. If the architecture permits it then use other formats instead of serialized objects, for example JSON.

    If you need to use YAML, use the `yaml.safe_load` function.


    ## Example
    The following example calls `pickle.loads` directly on a value provided by an incoming HTTP request. Pickle then creates a new value from untrusted data, and is therefore inherently unsafe.


    ```python

    from django.conf.urls import url
    import pickle

    def unsafe(pickled):
        return pickle.loads(pickled)

    urlpatterns = [
        url(r'^(?P<object>.*)$', unsafe)
    ]
    ```
    Changing the code to use `json.loads` instead of `pickle.loads` removes the vulnerability.


    ```python

    from django.conf.urls import url
    import json

    def safe(pickled):
        return json.loads(pickled)

    urlpatterns = [
        url(r'^(?P<object>.*)$', safe)
    ]

    ```

    # URL redirection from remote source
    Directly incorporating user input into a URL redirect request without validating the input can facilitate phishing attacks. In these attacks, unsuspecting users can be redirected to a malicious site that looks very similar to the real site they intend to visit, but which is controlled by the attacker.


    ## Recommendation
    To guard against untrusted URL redirection, it is advisable to avoid putting user input directly into a redirect URL. Instead, maintain a list of authorized redirects on the server; then choose from that list based on the user input provided.

    If this is not possible, then the user input should be validated in some other way, for example, by verifying that the target URL does not include an explicit host name.


    ## Example
    The following example shows an HTTP request parameter being used directly in a URL redirect without validating the input, which facilitates phishing attacks:


    ```python
    from flask import Flask, request, redirect

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        return redirect(target, code=302)

    ```
    If you know the set of valid redirect targets, you can maintain a list of them on the server and check that the user input is in that list:


    ```python
    from flask import Flask, request, redirect

    VALID_REDIRECT = "http://cwe.mitre.org/data/definitions/601.html"

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        if target == VALID_REDIRECT:
            return redirect(target, code=302)
        else:
            # ignore the target and redirect to the home page
            return redirect('/', code=302)

    ```
    Often this is not possible, so an alternative is to check that the target URL does not specify an explicit host name. For example, you can use the `urlparse` function from the Python standard library to parse the URL and check that the `netloc` attribute is empty.

    Note, however, that some cases are not handled as we desire out-of-the-box by `urlparse`, so we need to adjust two things, as shown in the example below:

    * Many browsers accept backslash characters (`\`) as equivalent to forward slash characters (`/`) in URLs, but the `urlparse` function does not.
    * Mistyped URLs such as `https:/example.com` or `https:///example.com` are parsed as having an empty `netloc` attribute, while browsers will still redirect to the correct site.

    ```python
    from flask import Flask, request, redirect
    from urllib.parse import urlparse

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        target = target.replace('\\', '')
        if not urlparse(target).netloc and not urlparse(target).scheme:
            # relative path, safe to redirect
            return redirect(target, code=302)
        # ignore the target and redirect to the home page
        return redirect('/', code=302)

    ```
    For Django application, you can use the function `url_has_allowed_host_and_scheme` to check that a URL is safe to redirect to, as shown in the following example:


    ```python
    from django.http import HttpResponseRedirect
    from django.shortcuts import redirect
    from django.utils.http import url_has_allowed_host_and_scheme
    from django.views import View

    class RedirectView(View):
        def get(self, request, *args, **kwargs):
            target = request.GET.get('target', '')
            if url_has_allowed_host_and_scheme(target, allowed_hosts=None):
                return HttpResponseRedirect(target)
            else:
                # ignore the target and redirect to the home page
                return redirect('/')
    ```
    Note that `url_has_allowed_host_and_scheme` handles backslashes correctly, so no additional processing is required.

    # XML external entity expansion
    Parsing untrusted XML files with a weakly configured XML parser may lead to an XML External Entity (XXE) attack. This type of attack uses external entity references to access arbitrary files on a system, carry out denial-of-service (DoS) attacks, or server-side request forgery. Even when the result of parsing is not returned to the user, DoS attacks are still possible and out-of-band data retrieval techniques may allow attackers to steal sensitive data.


    ## Recommendation
    The easiest way to prevent XXE attacks is to disable external entity handling when parsing untrusted data. How this is done depends on the library being used. Note that some libraries, such as recent versions of the XML libraries in the standard library of Python 3, disable entity expansion by default, so unless you have explicitly enabled entity expansion, no further action needs to be taken.

    We recommend using the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package, which has been created to prevent XML attacks (both XXE and XML bombs).


    ## Example
    The following example uses the `lxml` XML parser to parse a string `xml_src`. That string is from an untrusted source, so this code is vulnerable to an XXE attack, since the [ default parser](https://lxml.de/apidoc/lxml.etree.html#lxml.etree.XMLParser) from `lxml.etree` allows local external entities to be resolved.


    ```python
    from flask import Flask, request
    import lxml.etree

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = lxml.etree.fromstring(xml_src)
        return lxml.etree.tostring(doc)

    ```
    To guard against XXE attacks with the `lxml` library, you should create a parser with `resolve_entities` set to `false`. This means that no entity expansion is undertaken, although standard predefined entities such as `&gt;`, for writing `>` inside the text of an XML element, are still allowed.


    ```python
    from flask import Flask, request
    import lxml.etree

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        parser = lxml.etree.XMLParser(resolve_entities=False)
        doc = lxml.etree.fromstring(xml_src, parser=parser)
        return lxml.etree.tostring(doc)

    ```

    # XPath query built from user-controlled sources
    If an XPath expression is built using string concatenation, and the components of the concatenation include user input, it makes it very easy for a user to create a malicious XPath expression.


    ## Recommendation
    If user input must be included in an XPath expression, either sanitize the data or use variable references to safely embed it without altering the structure of the expression.


    ## Example
    In the example below, the xpath query is controlled by the user and hence leads to a vulnerability.


    ```python
    from lxml import etree
    from io import StringIO

    from django.urls import path
    from django.http import HttpResponse
    from django.template import Template, Context, Engine, engines


    def a(request):
        value = request.GET['xpath']
        f = StringIO('<foo><bar></bar></foo>')
        tree = etree.parse(f)
        r = tree.xpath("/tag[@id='%s']" % value)


    urlpatterns = [
        path('a', a)
    ]

    ```
    This can be fixed by using a parameterized query as shown below.


    ```python
    from lxml import etree
    from io import StringIO

    from django.urls import path
    from django.http import HttpResponse
    from django.template import Template, Context, Engine, engines


    def a(request):
        value = request.GET['xpath']
        f = StringIO('<foo><bar></bar></foo>')
        tree = etree.parse(f)
        r = tree.xpath("/tag[@id=$tagid]", tagid=value)


    urlpatterns = [
        path('a', a)
    ]

    ```

  queryHelp: "# Polynomial regular expression used on uncontrolled data\nSome regular\
    \ expressions take a long time to match certain input strings to the point where\
    \ the time it takes to match a string of length *n* is proportional to *n<sup>k</sup>*\
    \ or even *2<sup>n</sup>*. Such regular expressions can negatively affect performance,\
    \ or even allow a malicious user to perform a Denial of Service (\"DoS\") attack\
    \ by crafting an expensive input string for the regular expression to match.\n\
    \nThe regular expression engine provided by Python uses a backtracking non-deterministic\
    \ finite automata to implement regular expression matching. While this approach\
    \ is space-efficient and allows supporting advanced features like capture groups,\
    \ it is not time-efficient in general. The worst-case time complexity of such\
    \ an automaton can be polynomial or even exponential, meaning that for strings\
    \ of a certain shape, increasing the input length by ten characters may make the\
    \ automaton about 1000 times slower.\n\nTypically, a regular expression is affected\
    \ by this problem if it contains a repetition of the form `r*` or `r+` where the\
    \ sub-expression `r` is ambiguous in the sense that it can match some string in\
    \ multiple ways. More information about the precise circumstances can be found\
    \ in the references.\n\n\n## Recommendation\nModify the regular expression to\
    \ remove the ambiguity, or ensure that the strings matched with the regular expression\
    \ are short enough that the time-complexity does not matter.\n\n\n## Example\n\
    Consider this use of a regular expression, which removes all leading and trailing\
    \ whitespace in a string:\n\n```python\n\nre.sub(r\"^\\s+|\\s+$\", \"\", text)\
    \ # BAD\n```\nThe sub-expression `\"\\s+$\"` will match the whitespace characters\
    \ in `text` from left to right, but it can start matching anywhere within a whitespace\
    \ sequence. This is problematic for strings that do **not** end with a whitespace\
    \ character. Such a string will force the regular expression engine to process\
    \ each whitespace sequence once per whitespace character in the sequence.\n\n\
    This ultimately means that the time cost of trimming a string is quadratic in\
    \ the length of the string. So a string like `\"a b\"` will take milliseconds\
    \ to process, but a similar string with a million spaces instead of just one will\
    \ take several minutes.\n\nAvoid this problem by rewriting the regular expression\
    \ to not contain the ambiguity about when to start matching whitespace sequences.\
    \ For instance, by using a negative look-behind (`^\\s+|(?<!\\s)\\s+$`), or just\
    \ by using the built-in strip method (`text.strip()`).\n\nNote that the sub-expression\
    \ `\"^\\s+\"` is **not** problematic as the `^` anchor restricts when that sub-expression\
    \ can start matching, and as the regular expression engine matches from left to\
    \ right.\n\n\n## Example\nAs a similar, but slightly subtler problem, consider\
    \ the regular expression that matches lines with numbers, possibly written using\
    \ scientific notation:\n\n```python\n\n^0\\.\\d+E?\\d+$ # BAD\n```\nThe problem\
    \ with this regular expression is in the sub-expression `\\d+E?\\d+` because the\
    \ second `\\d+` can start matching digits anywhere after the first match of the\
    \ first `\\d+` if there is no `E` in the input string.\n\nThis is problematic\
    \ for strings that do **not** end with a digit. Such a string will force the regular\
    \ expression engine to process each digit sequence once per digit in the sequence,\
    \ again leading to a quadratic time complexity.\n\nTo make the processing faster,\
    \ the regular expression should be rewritten such that the two `\\d+` sub-expressions\
    \ do not have overlapping matches: `^0\\.\\d+(E\\d+)?$`.\n\n\n## Example\nSometimes\
    \ it is unclear how a regular expression can be rewritten to avoid the problem.\
    \ In such cases, it often suffices to limit the length of the input string. For\
    \ instance, the following regular expression is used to match numbers, and on\
    \ some non-number inputs it can have quadratic time complexity:\n\n```python\n\
    \nmatch = re.search(r'^(\\+|-)?(\\d+|(\\d*\\.\\d*))?(E|e)?([-+])?(\\d+)?$', str)\
    \ \n```\nIt is not immediately obvious how to rewrite this regular expression\
    \ to avoid the problem. However, you can mitigate performance issues by limiting\
    \ the length to 1000 characters, which will always finish in a reasonable amount\
    \ of time.\n\n```python\n\nif len(str) > 1000:\n    raise ValueError(\"Input too\
    \ long\")\n\nmatch = re.search(r'^(\\+|-)?(\\d+|(\\d*\\.\\d*))?(E|e)?([-+])?(\\\
    d+)?$', str) \n```\n\n## References\n* OWASP: [Regular expression Denial of Service\

Such regular expressions can negatively affect performance, or even allow a malicious user to perform a Denial of Service ("DoS") attack by crafting an expensive input string for the regular expression to match.

    The regular expression engine provided by Python uses a backtracking non-deterministic finite automata to implement regular expression matching. While this approach is space-efficient and allows supporting advanced features like capture groups, it is not time-efficient in general. The worst-case time complexity of such an automaton can be polynomial or even exponential, meaning that for strings of a certain shape, increasing the input length by ten characters may make the automaton about 1000 times slower.

    Typically, a regular expression is affected by this problem if it contains a repetition of the form `r*` or `r+` where the sub-expression `r` is ambiguous in the sense that it can match some string in multiple ways. More information about the precise circumstances can be found in the references.


    ## Recommendation
    Modify the regular expression to remove the ambiguity, or ensure that the strings matched with the regular expression are short enough that the time-complexity does not matter.


    ## Example
    Consider this regular expression:

    ```python

    ^_(__|.)+_$
    ```
    Its sub-expression `"(__|.)+?"` can match the string `"__"` either by the first alternative `"__"` to the left of the `"|"` operator, or by two repetitions of the second alternative `"."` to the right. Thus, a string consisting of an odd number of underscores followed by some other character will cause the regular expression engine to run for an exponential amount of time before rejecting the input.

    This problem can be avoided by rewriting the regular expression to remove the ambiguity between the two branches of the alternative inside the repetition:

    ```python

    ^_(__|[^_])+_$
    ```

    # Regular expression injection
    Constructing a regular expression with unsanitized user input is dangerous as a malicious user may be able to modify the meaning of the expression. In particular, such a user may be able to provide a regular expression fragment that takes exponential time in the worst case, and use that to perform a Denial of Service attack.


    ## Recommendation
    Before embedding user input into a regular expression, use a sanitization function such as `re.escape` to escape meta-characters that have a special meaning regarding regular expressions' syntax.


    ## Example
    The following examples are based on a simple Flask web server environment.

    The following example shows a HTTP request parameter that is used to construct a regular expression without sanitizing it first:


    ```python
    from flask import request, Flask
    import re


    @app.route("/direct")
    def direct():
        unsafe_pattern = request.args["pattern"]
        re.search(unsafe_pattern, "")


    @app.route("/compile")
    def compile():
        unsafe_pattern = request.args["pattern"]
        compiled_pattern = re.compile(unsafe_pattern)
        compiled_pattern.search("")

    ```
    Instead, the request parameter should be sanitized first, for example using the function `re.escape`. This ensures that the user cannot insert characters which have a special meaning in regular expressions.


    ```python
    from flask import request, Flask
    import re


    @app.route("/direct")
    def direct():
        unsafe_pattern = request.args['pattern']
        safe_pattern = re.escape(unsafe_pattern)
        re.search(safe_pattern, "")


    @app.route("/compile")
    def compile():
        unsafe_pattern = request.args['pattern']
        safe_pattern = re.escape(unsafe_pattern)
        compiled_pattern = re.compile(safe_pattern)
        compiled_pattern.search("")

    ```

    # XML internal entity expansion
    Parsing untrusted XML files with a weakly configured XML parser may be vulnerable to denial-of-service (DoS) attacks exploiting uncontrolled internal entity expansion.

    In XML, so-called *internal entities* are a mechanism for introducing an abbreviation for a piece of text or part of a document. When a parser that has been configured to expand entities encounters a reference to an internal entity, it replaces the entity by the data it represents. The replacement text may itself contain other entity references, which are expanded recursively. This means that entity expansion can increase document size dramatically.

    If untrusted XML is parsed with entity expansion enabled, a malicious attacker could submit a document that contains very deeply nested entity definitions, causing the parser to take a very long time or use large amounts of memory. This is sometimes called an *XML bomb* attack.


    ## Recommendation
    The safest way to prevent XML bomb attacks is to disable entity expansion when parsing untrusted data. Whether this can be done depends on the library being used. Note that some libraries, such as `lxml`, have measures enabled by default to prevent such DoS XML attacks, so unless you have explicitly set `huge_tree` to `True`, no further action is needed.

    We recommend using the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package, which has been created to prevent XML attacks (both XXE and XML bombs).


    ## Example
    The following example uses the `xml.etree` XML parser provided by the Python standard library to parse a string `xml_src`. That string is from an untrusted source, so this code is vulnerable to a DoS attack, since the `xml.etree` XML parser expands internal entities by default:


    ```python
    from flask import Flask, request
    import xml.etree.ElementTree as ET

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = ET.fromstring(xml_src)
        return ET.tostring(doc)

    ```
    It is not possible to guard against internal entity expansion with `xml.etree`, so to guard against these attacks, the following example uses the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package instead, which is not exposed to such internal entity expansion attacks.


    ```python
    from flask import Flask, request
    import defusedxml.ElementTree as ET

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = ET.fromstring(xml_src)
        return ET.tostring(doc)

    ```

    # Full server-side request forgery
    Directly incorporating user input into an HTTP request without validating the input can facilitate server-side request forgery (SSRF) attacks. In these attacks, the request may be changed, directed at a different server, or via a different protocol. This can allow the attacker to obtain sensitive information or perform actions with escalated privilege.

    We make a distinctions between how much of the URL an attacker can control:

    * **Full SSRF**: where the full URL can be controlled.
    * **Partial SSRF**: where only part of the URL can be controlled, such as the path component of a URL to a hardcoded domain.


    Partial control of a URL is often much harder to exploit. Therefore we have created a separate query for each of these.

    This query covers full SSRF, to find partial SSRF use the `py/partial-ssrf` query.


    ## Recommendation
    To guard against SSRF attacks you should avoid putting user-provided input directly into a request URL. On the application level, maintain a list of authorized URLs on the server and choose from that list based on the input provided. If that is not possible, one should verify the IP address for all user-controlled requests to ensure they are not private. This requires saving the verified IP address of each domain, then utilizing a custom HTTP adapter to ensure that future requests to that domain use the verified IP address. On the network level, you can segment the vulnerable application into its own LAN or block access to specific devices.


    ## Example
    The following example shows code vulnerable to a full SSRF attack, because it uses untrusted input (HTTP request parameter) directly to construct a URL. By using `evil.com#` as the `target` value, the requested URL will be `https://evil.com#.example.com/data/`. It also shows how to remedy the problem by using the user input select a known fixed string.


    ```python
    import requests
    from flask import Flask, request

    app = Flask(__name__)

    @app.route("/full_ssrf")
    def full_ssrf():
        target = request.args["target"]

        # BAD: user has full control of URL
        resp = requests.get("https://" + target + ".example.com/data/")

        # GOOD: `subdomain` is controlled by the server.
        subdomain = "europe" if target == "EU" else "world"
        resp = requests.get("https://" + subdomain + ".example.com/data/")

    ```

    ## Example
    The following example shows code vulnerable to a partial SSRF attack, because it uses untrusted input (HTTP request parameter) directly to construct a URL. By using `../transfer-funds-to/123?amount=456` as the `user_id` value, the requested URL will be `https://api.example.com/transfer-funds-to/123?amount=456`. It also shows how to remedy the problem by validating the input.


    ```python
    import requests
    from flask import Flask, request

    app = Flask(__name__)

    @app.route("/partial_ssrf")
    def partial_ssrf():
        user_id = request.args["user_id"]

        # BAD: user can fully control the path component of the URL
        resp = requests.get("https://api.example.com/user_info/" + user_id)

        if user_id.isalnum():
            # GOOD: user_id is restricted to be alpha-numeric, and cannot alter path component of URL
            resp = requests.get("https://api.example.com/user_info/" + user_id)

    ```

    # NoSQL Injection
    Passing user-controlled sources into NoSQL queries can result in a NoSQL injection flaw. This tainted NoSQL query containing a user-controlled source can then execute a malicious query in a NoSQL database such as MongoDB. In order for the user-controlled source to taint the NoSQL query, the user-controller source must be converted into a Python object using something like `json.loads` or `xmltodict.parse`.

    Because a user-controlled source is passed into the query, the malicious user can have complete control over the query itself. When the tainted query is executed, the malicious user can commit malicious actions such as bypassing role restrictions or accessing and modifying restricted data in the NoSQL database.


    ## Recommendation
    NoSQL injections can be prevented by escaping user-input's special characters that are passed into the NoSQL query from the user-supplied source. Alternatively, using a sanitize library such as MongoSanitizer will ensure that user-supplied sources can not act as a malicious query.


    ## Example
    In the example below, the user-supplied source is passed to a MongoDB function that queries the MongoDB database.


    ```python
    from flask import Flask, request
    from flask_pymongo import PyMongo
    import json

    mongo = PyMongo(app)


    @app.route("/")
    def home_page():
        unsanitized_search = request.args['search']
        json_search = json.loads(unsanitized_search)

        result = mongo.db.user.find({'name': json_search})

    ```
    This can be fixed by using a sanitizer library like MongoSanitizer as shown in this annotated code version below.


    ```python
    from flask import Flask, request
    from flask_pymongo import PyMongo
    from mongosanitizer.sanitizer import sanitize
    import json

    mongo = PyMongo(app)


    @app.route("/")
    def home_page():
        unsafe_search = request.args['search']
        json_search = json.loads(unsafe_search)
        safe_search = sanitize(unsanitized_search)

        result = client.db.collection.find_one({'data': safe_search})

    ```

    # 'input' function used in Python 2
    In Python 2, a call to the `input()` function, `input(prompt)` is equivalent to `eval(raw_input(prompt))`. Evaluating user input without any checking can be a serious security flaw.


    ## Recommendation
    Get user input with `raw_input(prompt)` and then validate that input before evaluating. If the expected input is a number or string, then `ast.literal_eval()` can always be used safely.

    # Binding a socket to all network interfaces
    Sockets can be used to communicate with other machines on a network. You can use the (IP address, port) pair to define the access restrictions for the socket you create. When using the built-in Python `socket` module (for instance, when building a message sender service or an FTP server data transmitter), one has to bind the port to some interface. When you bind the port to all interfaces using `0.0.0.0` as the IP address, you essentially allow it to accept connections from any IPv4 address provided that it can get to the socket via routing. Binding to all interfaces is therefore associated with security risks.


    ## Recommendation
    Bind your service incoming traffic only to a dedicated interface. If you need to bind more than one interface using the built-in `socket` module, create multiple sockets (instead of binding to one socket to all interfaces).


    ## Example
    In this example, two sockets are insecure because they are bound to all interfaces; one through the `0.0.0.0` notation and another one through an empty string `''`.


    ```python
    import socket

    # binds to all interfaces, insecure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('0.0.0.0', 31137))

    # binds to all interfaces, insecure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('', 4040))

    # binds only to a dedicated interface, secure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('84.68.10.12', 8080))

    ```

    # Construction of a cookie using user-supplied input
    Constructing cookies from user input can allow an attacker to control a user's cookie. This may lead to a session fixation attack. Additionally, client code may not expect a cookie to contain attacker-controlled data, and fail to sanitize it for common vulnerabilities such as Cross Site Scripting (XSS). An attacker manipulating the raw cookie header may additionally be able to set cookie attributes such as `HttpOnly` to insecure values.


    ## Recommendation
    Do not use raw user input to construct cookies.


    ## Example
    In the following cases, a cookie is constructed for a Flask response using user input. The first uses `set_cookie`, and the second sets a cookie's raw value through the `set-cookie` header.


    ```python
    from flask import request, make_response


    @app.route("/1")
    def set_cookie():
        resp = make_response()
        resp.set_cookie(request.args["name"], # BAD: User input is used to set the cookie's name and value
                        value=request.args["name"])
        return resp


    @app.route("/2")
    def set_cookie_header():
        resp = make_response()
        resp.headers['Set-Cookie'] = f"{request.args['name']}={request.args['name']};" # BAD: User input is used to set the raw cookie header.
        return resp

    ```

    # Incomplete regular expression for hostnames
    Sanitizing untrusted URLs is a common technique for preventing attacks such as request forgeries and malicious redirections. Often, this is done by checking that the host of a URL is in a set of allowed hosts.

    If a regular expression implements such a check, it is easy to accidentally make the check too permissive by not escaping the `.` meta-characters appropriately. Even if the check is not used in a security-critical context, the incomplete check may still cause undesirable behaviors when it accidentally succeeds.


    ## Recommendation
    Escape all meta-characters appropriately when constructing regular expressions for security checks, and pay special attention to the `.` meta-character.


    ## Example
    The following example code checks that a URL redirection will reach the `example.com` domain, or one of its subdomains.


    ```python
    from flask import Flask, request, redirect
    import re

    app = Flask(__name__)

    UNSAFE_REGEX = re.compile("(www|beta).example.com/")
    SAFE_REGEX = re.compile(r"(www|beta)\.example\.com/")

    @app.route('/some/path/bad')
    def unsafe(request):
        target = request.args.get('target', '')
        if UNSAFE_REGEX.match(target):
            return redirect(target)

    @app.route('/some/path/good')
    def safe(request):
        target = request.args.get('target', '')
        if SAFE_REGEX.match(target):
            return redirect(target)

    ```
    The `unsafe` check is easy to bypass because the unescaped `.` allows for any character before `example.com`, effectively allowing the redirect to go to an attacker-controlled domain such as `wwwXexample.com`.

    The `safe` check closes this vulnerability by escaping the `.` so that URLs of the form `wwwXexample.com` are rejected.

    # Incomplete URL substring sanitization
    Sanitizing untrusted URLs is a common technique for preventing attacks such as request forgeries and malicious redirections. Usually, this is done by checking that the host of a URL is in a set of allowed hosts.

    However, treating the URL as a string and checking if one of the allowed hosts is a substring of the URL is very prone to errors. Malicious URLs can bypass such security checks by embedding one of the allowed hosts in an unexpected location.

    Even if the substring check is not used in a security-critical context, the incomplete check may still cause undesirable behaviors when the check succeeds accidentally.


    ## Recommendation
    Parse a URL before performing a check on its host value, and ensure that the check handles arbitrary subdomain sequences correctly.


    ## Example
    The following example code checks that a URL redirection will reach the `example.com` domain.


    ```python
    from flask import Flask, request, redirect
    from urllib.parse import urlparse

    app = Flask(__name__)

    # Not safe, as "evil-example.net/example.com" would be accepted

    @app.route('/some/path/bad1')
    def unsafe1(request):
        target = request.args.get('target', '')
        if "example.com" in target:
            return redirect(target)

    # Not safe, as "benign-looking-prefix-example.com" would be accepted

    @app.route('/some/path/bad2')
    def unsafe2(request):
        target = request.args.get('target', '')
        if target.endswith("example.com"):
            return redirect(target)



    #Simplest and safest approach is to use an allowlist

    @app.route('/some/path/good1')
    def safe1(request):
        allowlist = [
            "example.com/home",
            "example.com/login",
        ]
        target = request.args.get('target', '')
        if target in allowlist:
            return redirect(target)

    #More complex example allowing sub-domains.

    @app.route('/some/path/good2')
    def safe2(request):
        target = request.args.get('target', '')
        host = urlparse(target).hostname
        #Note the '.' preceding example.com
        if host and host.endswith(".example.com"):
            return redirect(target)


    ```
    The first two examples show unsafe checks that are easily bypassed. In `unsafe1` the attacker can simply add `example.com` anywhere in the url. For example, `http://evil-example.net/example.com`.

    In `unsafe2` the attacker must use a hostname ending in `example.com`, but that is easy to do. For example, `http://benign-looking-prefix-example.com`.

    The second two examples show safe checks. In `safe1`, an allowlist is used. Although fairly inflexible, this is easy to get right and is most likely to be safe.

    In `safe2`, `urlparse` is used to parse the URL, then the hostname is checked to make sure it ends with `.example.com`.

    # Overly permissive regular expression range
    It's easy to write a regular expression range that matches a wider range of characters than you intended. For example, `/[a-zA-z]/` matches all lowercase and all uppercase letters, as you would expect, but it also matches the characters: `` [ \ ] ^ _ ` ``.

    Another common problem is failing to escape the dash character in a regular expression. An unescaped dash is interpreted as part of a range. For example, in the character class `[a-zA-Z0-9%=.,-_]` the last character range matches the 55 characters between `,` and `_` (both included), which overlaps with the range `[0-9]` and is clearly not intended by the writer.


    ## Recommendation
    Avoid any confusion about which characters are included in the range by writing unambiguous regular expressions. Always check that character ranges match only the expected characters.


    ## Example
    The following example code is intended to check whether a string is a valid 6 digit hex color.

    ```python

    import re
    def is_valid_hex_color(color):
        return re.match(r'^#[0-9a-fA-f]{6}$', color) is not None

    ```
    However, the `A-f` range is overly large and matches every uppercase character. It would parse a "color" like `#XXYYZZ` as valid.

    The fix is to use an uppercase `A-F` range instead.

    ```python

    import re
    def is_valid_hex_color(color):
        return re.match(r'^#[0-9a-fA-F]{6}$', color) is not None

    ```

    # Uncontrolled data used in path expression
    Accessing files using paths constructed from user-controlled data can allow an attacker to access unexpected resources. This can result in sensitive information being revealed or deleted, or an attacker being able to influence behavior by modifying unexpected files.


    ## Recommendation
    Validate paths constructed from untrusted user input before using them to access files.

    The choice of validation depends on the use case.

    If you want to allow paths spanning multiple folders, a common strategy is to make sure that the constructed file path is contained within a safe root folder. First, normalize the path using `os.path.normpath` or `os.path.realpath` (make sure to use the latter if symlinks are a consideration) to remove any internal ".." segments and/or follow links. Then check that the normalized path starts with the root folder. Note that the normalization step is important, since otherwise even a path that starts with the root folder could be used to access files outside the root folder.

    More restrictive options include using a library function like `werkzeug.utils.secure_filename` to eliminate any special characters from the file path, or restricting the path to a known list of safe paths. These options are safe, but can only be used in particular circumstances.


    ## Example
    In the first example, a file name is read from an HTTP request and then used to access a file. However, a malicious user could enter a file name that is an absolute path, such as `"/etc/passwd"`.

    In the second example, it appears that the user is restricted to opening a file within the `"user"` home directory. However, a malicious user could enter a file name containing special characters. For example, the string `"../../../etc/passwd"` will result in the code reading the file located at `"/server/static/images/../../../etc/passwd"`, which is the system's password file. This file would then be sent back to the user, giving them access to all the system's passwords. Note that a user could also use an absolute path here, since the result of `os.path.join("/server/static/images/", "/etc/passwd")` is `"/etc/passwd"`.

    In the third example, the path used to access the file system is normalized *before* being checked against a known prefix. This ensures that regardless of the user input, the resulting path is safe.


    ```python
    import os.path
    from flask import Flask, request, abort

    app = Flask(__name__)

    @app.route("/user_picture1")
    def user_picture1():
        filename = request.args.get('p')
        # BAD: This could read any file on the file system
        data = open(filename, 'rb').read()
        return data

    @app.route("/user_picture2")
    def user_picture2():
        base_path = '/server/static/images'
        filename = request.args.get('p')
        # BAD: This could still read any file on the file system
        data = open(os.path.join(base_path, filename), 'rb').read()
        return data

    @app.route("/user_picture3")
    def user_picture3():
        base_path = '/server/static/images'
        filename = request.args.get('p')
        #GOOD -- Verify with normalised version of path
        fullpath = os.path.normpath(os.path.join(base_path, filename))
        if not fullpath.startswith(base_path):
            raise Exception("not allowed")
        data = open(fullpath, 'rb').read()
        return data

    ```

    # Arbitrary file write during tarfile extraction
    Extracting files from a malicious tar archive without validating that the destination file path is within the destination directory can cause files outside the destination directory to be overwritten, due to the possible presence of directory traversal elements (`..`) in archive paths.

    Tar archives contain archive entries representing each file in the archive. These entries include a file path for the entry, but these file paths are not restricted and may contain unexpected special elements such as the directory traversal element (`..`). If these file paths are used to determine an output file to write the contents of the archive item to, then the file may be written to an unexpected location. This can result in sensitive information being revealed or deleted, or an attacker being able to influence behavior by modifying unexpected files.

    For example, if a tar archive contains a file entry `..\sneaky-file`, and the tar archive is extracted to the directory `c:\output`, then naively combining the paths would result in an output file path of `c:\output\..\sneaky-file`, which would cause the file to be written to `c:\sneaky-file`.


    ## Recommendation
    Ensure that output paths constructed from tar archive entries are validated to prevent writing files to unexpected locations.

    The recommended way of writing an output file from a tar archive entry is to check that `".."` does not occur in the path.


    ## Example
    In this example an archive is extracted without validating file paths. If `archive.tar` contained relative paths (for instance, if it were created by something like `tar -cf archive.tar ../file.txt`) then executing this code could write to locations outside the destination directory.


    ```python
    import sys
    import tarfile

    with tarfile.open(sys.argv[1]) as tar:
        #BAD : This could write any file on the filesystem.
        for entry in tar:
            tar.extract(entry, "/tmp/unpack/")

    ```
    To fix this vulnerability, we need to check that the path does not contain any `".."` elements in it.


    ```python
    import sys
    import tarfile
    import os.path

    with tarfile.open(sys.argv[1]) as tar:
        for entry in tar:
            #GOOD: Check that entry is safe
            if os.path.isabs(entry.name) or ".." in entry.name:
                raise ValueError("Illegal tar archive entry")
            tar.extract(entry, "/tmp/unpack/")

    ```

    \ }}{% endif %}{% endfor %}\n\n```\nIn the following case, user input is not used\
    \ to construct the template. Instead, it is only used as the parameters to render\
    \ the template, which is safe.\n\n\n```python\nfrom django.urls import path\n\
    from django.http import HttpResponse\nfrom jinja2 import Template, escape\n\n\n\
    def a(request):\n    # GOOD: Template is a constant, not constructed from user\

    \ is used, preventing remote code execution.\n\n\n```python\nfrom django.urls\
    \ import path\nfrom django.http import HttpResponse\nfrom jinja2 import escape\n\
    from jinja2.sandbox import SandboxedEnvironment\n\n\ndef a(request):\n    env\

    # Uncontrolled command line
    Code that passes user input directly to `exec`, `eval`, or some other library routine that executes a command, allows the user to execute malicious code.


    ## Recommendation
    If possible, use hard-coded string literals to specify the command to run or the library to load. Instead of passing the user input directly to the process or library function, examine the user input and then choose among hard-coded string literals.

    If the applicable libraries or commands cannot be determined at compile time, then add code to verify that the user input string is safe before using it.


    ## Example
    The following example shows two functions. The first is unsafe as it takes a shell script that can be changed by a user, and passes it straight to `subprocess.call()` without examining it first. The second is safe as it selects the command from a predefined allowlist.


    ```python

    urlpatterns = [
        # Route to command_execution
        url(r'^command-ex1$', command_execution_unsafe, name='command-execution-unsafe'),
        url(r'^command-ex2$', command_execution_safe, name='command-execution-safe')
    ]

    COMMANDS = {
        "list" :"ls",
        "stat" : "stat"
    }

    def command_execution_unsafe(request):
        if request.method == 'POST':
            action = request.POST.get('action', '')
            #BAD -- No sanitizing of input
            subprocess.call(["application", action])

    def command_execution_safe(request):
        if request.method == 'POST':
            action = request.POST.get('action', '')
            #GOOD -- Use an allowlist
            subprocess.call(["application", COMMANDS[action]])

    # Jinja2 templating with autoescape=False
    Cross-site scripting (XSS) attacks can occur if untrusted input is not escaped. This applies to templates as well as code. The `jinja2` templates may be vulnerable to XSS if the environment has `autoescape` set to `False`. Unfortunately, `jinja2` sets `autoescape` to `False` by default. Explicitly setting `autoescape` to `True` when creating an `Environment` object will prevent this.


    ## Recommendation
    Avoid setting jinja2 autoescape to False. Jinja2 provides the function `select_autoescape` to make sure that the correct auto-escaping is chosen. For example, it can be used when creating an environment `Environment(autoescape=select_autoescape(['html', 'xml'])`


    ## Example
    The following example is a minimal Flask app which shows a safe and an unsafe way to render the given name back to the page. The first view is unsafe as `first_name` is not escaped, leaving the page vulnerable to cross-site scripting attacks. The second view is safe as `first_name` is escaped, so it is not vulnerable to cross-site scripting attacks.


    ```python
    from flask import Flask, request, make_response, escape
    from jinja2 import Environment, select_autoescape, FileSystemLoader

    app = Flask(__name__)
    loader = FileSystemLoader( searchpath="templates/" )

    unsafe_env = Environment(loader=loader)
    safe1_env = Environment(loader=loader, autoescape=True)
    safe2_env = Environment(loader=loader, autoescape=select_autoescape())

        template = env.get_template('template.html')

    # Reflected server-side cross-site scripting
    Directly writing user input (for example, an HTTP request parameter) to a webpage without properly sanitizing the input first, allows for a cross-site scripting vulnerability.


    ## Recommendation
    To guard against cross-site scripting, consider escaping the input before writing user input to the page. The standard library provides escaping functions: `html.escape()` for Python 3.2 upwards or `cgi.escape()` older versions of Python. Most frameworks also provide their own escaping functions, for example `flask.escape()`.


    ## Example
    The following example is a minimal flask app which shows a safe and unsafe way to render the given name back to the page. The first view is unsafe as `first_name` is not escaped, leaving the page vulnerable to cross-site scripting attacks. The second view is safe as `first_name` is escaped, so it is not vulnerable to cross-site scripting attacks.


    ```python
    from flask import Flask, request, make_response, escape

    app = Flask(__name__)

    @app.route('/unsafe')
    def unsafe():
        first_name = request.args.get('name', '')
        return make_response("Your name is " + first_name)

    @app.route('/safe')
    def safe():
        first_name = request.args.get('name', '')
        return make_response("Your name is " + escape(first_name))

    # SQL query built from user-controlled sources
    If a database query (such as a SQL or NoSQL query) is built from user-provided data without sufficient sanitization, a user may be able to run malicious database queries.

    This also includes using the `TextClause` class in the `[SQLAlchemy](https://pypi.org/project/SQLAlchemy/)` PyPI package, which is used to represent a literal SQL fragment and is inserted directly into the final SQL when used in a query built using the ORM.


    ## Recommendation
    Most database connector libraries offer a way of safely embedding untrusted data into a query by means of query parameters or prepared statements.


    ## Example
    In the following snippet, a user is fetched from the database using three different queries.

    In the first case, the query string is built by directly using string formatting from a user-supplied request parameter. The parameter may include quote characters, so this code is vulnerable to a SQL injection attack.

    In the second case, the user-supplied request attribute is passed to the database using query parameters. The database connector library will take care of escaping and inserting quotes as needed.

    In the third case, the placeholder in the SQL string has been manually quoted. Since most databaseconnector libraries will insert their own quotes, doing so yourself will make the code vulnerable to SQL injection attacks. In this example, if `username` was `; DROP ALL TABLES -- `, the final SQL query would be `SELECT * FROM users WHERE username = ''; DROP ALL TABLES -- ''`


    ```python
    from django.conf.urls import url
    from django.db import connection


    def show_user(request, username):
        with connection.cursor() as cursor:
            # BAD -- Using string formatting
            cursor.execute("SELECT * FROM users WHERE username = '%s'" % username)
            user = cursor.fetchone()

            # GOOD -- Using parameters
            cursor.execute("SELECT * FROM users WHERE username = %s", username)
            user = cursor.fetchone()

            # BAD -- Manually quoting placeholder (%s)
            cursor.execute("SELECT * FROM users WHERE username = '%s'", username)
            user = cursor.fetchone()

    urlpatterns = [url(r'^users/(?P<username>[^/]+)$', show_user)]

    ```

    # LDAP query built from user-controlled sources
    If an LDAP query or DN is built using string concatenation or string formatting, and the components of the concatenation include user input without any proper sanitization, a user is likely to be able to run malicious LDAP queries.


    ## Recommendation
    If user input must be included in an LDAP query or DN, it should be escaped to avoid a malicious user providing special characters that change the meaning of the query. In Python2, user input should be escaped with `ldap.dn.escape_dn_chars` or `ldap.filter.escape_filter_chars`, while in Python3, user input should be escaped with `ldap3.utils.dn.escape_rdn` or `ldap3.utils.conv.escape_filter_chars` depending on the component tainted by the user. A good practice is to escape filter characters that could change the meaning of the query (https://tools.ietf.org/search/rfc4515\#section-3).


    ## Example
    In the following examples, the code accepts both `username` and `dc` from the user, which it then uses to build a LDAP query and DN.

    The first and the second example uses the unsanitized user input directly in the search filter and DN for the LDAP query. A malicious user could provide special characters to change the meaning of these components, and search for a completely different set of values.


    ```python
    from flask import request, Flask
    import ldap


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        dn = "dc={}".format(unsafe_dc)
        search_filter = "(user={})".format(unsafe_filter)

        ldap_connection = ldap.initialize("ldap://127.0.0.1")
        user = ldap_connection.search_s(
            dn, ldap.SCOPE_SUBTREE, search_filter)

    ```

    ```python
    from flask import request, Flask
    import ldap3


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        dn = "dc={}".format(unsafe_dc)
        search_filter = "(user={})".format(unsafe_filter)

        srv = ldap3.Server('ldap://127.0.0.1')
        conn = ldap3.Connection(srv, user=dn, auto_bind=True)
        conn.search(dn, search_filter)

    ```
    In the third and fourth example, the input provided by the user is sanitized before it is included in the search filter or DN. This ensures the meaning of the query cannot be changed by a malicious user.


    ```python
    from flask import request, Flask
    import ldap
    import ldap.filter
    import ldap.dn


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        safe_dc = ldap.dn.escape_dn_chars(unsafe_dc)
        safe_filter = ldap.filter.escape_filter_chars(unsafe_filter)

        dn = "dc={}".format(safe_dc)
        search_filter = "(user={})".format(safe_filter)

        ldap_connection = ldap.initialize("ldap://127.0.0.1")
        user = ldap_connection.search_s(
            dn, ldap.SCOPE_SUBTREE, search_filter)

    ```

    ```python
    from flask import request, Flask
    import ldap3
    from ldap3.utils.dn import escape_rdn
    from ldap3.utils.conv import escape_filter_chars


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        safe_dc = escape_rdn(unsafe_dc)
        safe_filter = escape_filter_chars(unsafe_filter)

        dn = "dc={}".format(safe_dc)
        search_filter = "(user={})".format(safe_filter)

        srv = ldap3.Server('ldap://127.0.0.1')
        conn = ldap3.Connection(srv, user=dn, auto_bind=True)
        conn.search(dn, search_filter)

    ```

    # Code injection
    Directly evaluating user input (for example, an HTTP request parameter) as code without properly sanitizing the input first allows an attacker arbitrary code execution. This can occur when user input is passed to code that interprets it as an expression to be evaluated, such as `eval` or `exec`.


    ## Recommendation
    Avoid including user input in any expression that may be dynamically evaluated. If user input must be included, use context-specific escaping before including it. It is important that the correct escaping is used for the type of evaluation that will occur.


    ## Example
    The following example shows two functions setting a name from a request. The first function uses `exec` to execute the `setname` function. This is dangerous as it can allow a malicious user to execute arbitrary code on the server. For example, the user could supply the value `"' + subprocess.call('rm -rf') + '"` to destroy the server's file system. The second function calls the `setname` function directly and is thus safe.


    ```python

    urlpatterns = [
        # Route to code_execution
        url(r'^code-ex1$', code_execution_bad, name='code-execution-bad'),
        url(r'^code-ex2$', code_execution_good, name='code-execution-good')
    ]

    def code_execution(request):
        if request.method == 'POST':
            first_name = base64.decodestring(request.POST.get('first_name', ''))
            #BAD -- Allow user to define code to be run.
            exec("setname('%s')" % first_name)

    def code_execution(request):
        if request.method == 'POST':
            first_name = base64.decodestring(request.POST.get('first_name', ''))
            #GOOD --Call code directly
            setname(first_name)

    ```

    # Log Injection
    If unsanitized user input is written to a log entry, a malicious user may be able to forge new log entries.

    Forgery can occur if a user provides some input with characters that are interpreted when the log output is displayed. If the log is displayed as a plain text file, then new line characters can be used by a malicious user to create the appearance of multiple log entries. If the log is displayed as HTML, then arbitrary HTML may be included to spoof log entries.


    ## Recommendation
    User input should be suitably sanitized before it is logged.

    If the log entries are plain text then line breaks should be removed from user input, using for example `replace(old, new)` or similar. Care should also be taken that user input is clearly marked in log entries, and that a malicious user cannot cause confusion in other ways.

    For log entries that will be displayed in HTML, user input should be HTML encoded before being logged, to prevent forgery and other forms of HTML injection.


    ## Example
    In the example, the name provided by the user is recorded using the log output function (`logging.info` or `app.logger.info`, etc.). In these four cases, the name provided by the user is not provided The processing is recorded. If a malicious user provides `Guest%0D%0AUser name: Admin` as a parameter, the log entry will be divided into two lines, the first line is `User name: Guest` code&gt;, the second line is `User name: Admin`.

    ```
    In a good example, the program uses the `replace` function to provide parameter processing to the user, and replace `\r\n` and `\n` with empty characters. To a certain extent, the occurrence of log injection vulnerabilities is reduced.

    # Information exposure through an exception
    Software developers often add stack traces to error messages, as a debugging aid. Whenever that error message occurs for an end user, the developer can use the stack trace to help identify how to fix the problem. In particular, stack traces can tell the developer more about the sequence of events that led to a failure, as opposed to merely the final state of the software when the error occurred.

    Unfortunately, the same information can be useful to an attacker. The sequence of class names in a stack trace can reveal the structure of the application as well as any internal components it relies on. Furthermore, the error message at the top of a stack trace can include information such as server-side file names and SQL code that the application relies on, allowing an attacker to fine-tune a subsequent injection attack.


    ## Recommendation
    Send the user a more generic error message that reveals less information. Either suppress the stack trace entirely, or log it only on the server.


    ## Example
    In the following example, an exception is handled in two different ways. In the first version, labeled BAD, the exception is sent back to the remote user by returning it from the function. As such, the user is able to see a detailed stack trace, which may contain sensitive information. In the second version, the error message is logged only on the server, and a generic error message is displayed to the user. That way, the developers can still access and use the error log, but remote users will not see the information.


    ```python
    from flask import Flask
    app = Flask(__name__)


    import traceback

    def do_computation():
        raise Exception("Secret info")

    # BAD
    @app.route('/bad')
    def server_bad():
        try:
            do_computation()
        except Exception as e:
            return traceback.format_exc()

    # GOOD
    @app.route('/good')
    def server_good():
        try:
            do_computation()
        except Exception as e:
            log(traceback.format_exc())
            return "An internal error has occurred!"

    ```

    Running a Flask application with debug mode enabled may allow an attacker to gain access through the Werkzeug debugger.


    ## Recommendation
    Ensure that Flask applications that are run in a production environment have debugging disabled.


    ## Example
    Running the following code starts a Flask webserver that has debugging enabled. By visiting `/crash`, it is possible to gain access to the debugger, and run arbitrary code through the interactive debugger.


    ```python
    from flask import Flask

    app = Flask(__name__)

    # PAM authorization bypass due to incorrect usage
    Using only a call to `pam_authenticate` to check the validity of a login can lead to authorization bypass vulnerabilities.

    A `pam_authenticate` only verifies the credentials of a user. It does not check if a user has an appropriate authorization to actually login. This means a user with an expired login or a password can still access the system.


    ## Recommendation
    A call to `pam_authenticate` should be followed by a call to `pam_acct_mgmt` to check if a user is allowed to login.


    ## Example
    In the following example, the code only checks the credentials of a user. Hence, in this case, a user with expired credentials can still login. This can be verified by creating a new user account, expiring it with ``` chage -E0 `username`  ``` and then trying to log in.


    ```python
    libpam                    = CDLL(find_library("pam"))

    pam_authenticate          = libpam.pam_authenticate
    pam_authenticate.restype  = c_int
    pam_authenticate.argtypes = [PamHandle, c_int]

    def authenticate(username, password, service='login'):
        def my_conv(n_messages, messages, p_response, app_data):
            """
            Simple conversation function that responds to any prompt where the echo is off with the supplied password
            """
            ...

        handle = PamHandle()
        conv   = PamConv(my_conv, 0)
        retval = pam_start(service, username, byref(conv), byref(handle))

        retval = pam_authenticate(handle, 0)
        return retval == 0

    ```
    This can be avoided by calling `pam_acct_mgmt` call to verify access as has been done in the snippet shown below.


    ```python
    libpam                    = CDLL(find_library("pam"))

    pam_authenticate          = libpam.pam_authenticate
    pam_authenticate.restype  = c_int
    pam_authenticate.argtypes = [PamHandle, c_int]

    pam_acct_mgmt          = libpam.pam_acct_mgmt
    pam_acct_mgmt.restype  = c_int
    pam_acct_mgmt.argtypes = [PamHandle, c_int]

    def authenticate(username, password, service='login'):
        def my_conv(n_messages, messages, p_response, app_data):
            """

            """
            ...

        handle = PamHandle()
        conv   = PamConv(my_conv, 0)
        retval = pam_start(service, username, byref(conv), byref(handle))

        retval = pam_authenticate(handle, 0)
        if retval == 0:
            retval = pam_acct_mgmt(handle, 0)
        return retval == 0

    # Accepting unknown SSH host keys when using Paramiko
    In the Secure Shell (SSH) protocol, host keys are used to verify the identity of remote hosts. Accepting unknown host keys may leave the connection open to man-in-the-middle attacks.


    ## Recommendation
    Do not accept unknown host keys. In particular, do not set the default missing host key policy for the Paramiko library to either `AutoAddPolicy` or `WarningPolicy`. Both of these policies continue even when the host key is unknown. The default setting of `RejectPolicy` is secure because it throws an exception when it encounters an unknown host key.


    ## Example
    The following example shows two ways of opening an SSH connection to `example.com`. The first function sets the missing host key policy to `AutoAddPolicy`. If the host key verification fails, the client will continue to interact with the server, even though the connection may be compromised. The second function sets the host key policy to `RejectPolicy`, and will throw an exception if the host key verification fails.


    ```python
    from paramiko.client import SSHClient, AutoAddPolicy, RejectPolicy

    def unsafe_connect():
        client = SSHClient()
        client.set_missing_host_key_policy(AutoAddPolicy)
        client.connect("example.com")

        # ... interaction with server

        client.close()

    def safe_connect():
        client = SSHClient()
        client.set_missing_host_key_policy(RejectPolicy)
        client.connect("example.com")

        # ... interaction with server

        client.close()

    ```

    # Request without certificate validation
    Encryption is key to the security of most, if not all, online communication. Using Transport Layer Security (TLS) can ensure that communication cannot be interrupted by an interloper. For this reason, it is unwise to disable the verification that TLS provides. Functions in the `requests` module provide verification by default, and it is only when explicitly turned off using `verify=False` that no verification occurs.


    ## Recommendation
    Never use `verify=False` when making a request.


    ## Example
    The example shows two unsafe calls to [semmle.com](https://semmle.com), followed by various safe alternatives.


    ```python
    import requests

    #Unsafe requests

    requests.get('https://semmle.com', verify=False) # UNSAFE
    requests.get('https://semmle.com', verify=0) # UNSAFE

    #Various safe options

    requests.get('https://semmle.com', verify=True) # Explicitly safe
    requests.get('https://semmle.com', verify="/path/to/cert/")
    requests.get('https://semmle.com') # The default is to verify.

    #Wrapper to ensure safety

    def make_safe_request(url, verify_cert):
        if not verify_cert:
            raise Exception("Trying to make unsafe request")
        return requests.get(url, verify_cert)

    # Clear-text logging of sensitive information
    If sensitive data is written to a log entry it could be exposed to an attacker who gains access to the logs.

    Potential attackers can obtain sensitive user data when the log output is displayed. Additionally that data may expose system information such as full path names, system information, and sometimes usernames and passwords.


    ## Recommendation
    Sensitive data should not be logged.


    ## Example
    In the example the entire process environment is logged using \`print\`. Regular users of the production deployed application should not have access to this much information about the environment configuration.


    ```python
    # BAD: Logging cleartext sensitive data
    import os
    print(f"[INFO] Environment: {os.environ}")
    ```
    In the second example the data that is logged is not sensitive.

    not_sensitive_data = {'a': 1, 'b': 2}
    # GOOD: it is fine to log data that is not sensitive
    print(f"[INFO] Some object contains: {not_sensitive_data}")

    # Clear-text storage of sensitive information
    Sensitive information that is stored unencrypted is accessible to an attacker who gains access to the storage. This is particularly important for cookies, which are stored on the machine of the end-user.


    ## Recommendation
    Ensure that sensitive information is always encrypted before being stored. If possible, avoid placing sensitive information in cookies altogether. Instead, prefer storing, in the cookie, a key that can be used to look up the sensitive information.

    In general, decrypt sensitive information only at the point where it is necessary for it to be used in cleartext.

    Be aware that external processes often store the `standard out` and `standard error` streams of the application, causing logged sensitive information to be stored as well.


    ## Example
    The following example code stores user credentials (in this case, their password) in a cookie in plain text:


    ```python
    from flask import Flask, make_response, request

    app = Flask("Leak password")

    @app.route('/')
    def index():
        password = request.args.get("password")
        resp = make_response(render_template(...))
        resp.set_cookie("password", password)
        return resp

    ```
    Instead, the credentials should be encrypted, for instance by using the `cryptography` module, or not stored at all.

    # Use of weak cryptographic key
    Modern encryption relies on it being computationally infeasible to break the cipher and decode a message without the key. As computational power increases, the ability to break ciphers grows and keys need to become larger.

    The three main asymmetric key algorithms currently in use are Rivest–Shamir–Adleman (RSA) cryptography, Digital Signature Algorithm (DSA), and Elliptic-curve cryptography (ECC). With current technology, key sizes of 2048 bits for RSA and DSA, or 256 bits for ECC, are regarded as unbreakable.


    ## Recommendation
    Increase the key size to the recommended amount or larger. For RSA or DSA this is at least 2048 bits, for ECC this is at least 256 bits.

    # Use of a broken or weak cryptographic algorithm
    Using broken or weak cryptographic algorithms may compromise security guarantees such as confidentiality, integrity, and authenticity.

    Many cryptographic algorithms are known to be weak or flawed. The security guarantees of a system often rely on the underlying cryptography, so using a weak algorithm can have severe consequences. For example:

    * If a weak encryption algorithm is used, an attacker may be able to decrypt sensitive data.
    * If a weak algorithm is used for digital signatures, an attacker may be able to forge signatures and impersonate legitimate users.
    This query alerts on any use of a weak cryptographic algorithm that is not a hashing algorithm. Use of broken or weak cryptographic hash functions are handled by the `py/weak-sensitive-data-hashing` query.


    ## Recommendation
    Ensure that you use a strong, modern cryptographic algorithm, such as AES-128 or RSA-2048.


    ## Example
    The following code uses the `pycryptodome` library to encrypt some secret data. When you create a cipher using `pycryptodome` you must specify the encryption algorithm to use. The first example uses DES, which is an older algorithm that is now considered weak. The second example uses AES, which is a stronger modern algorithm.


    ```python
    from Crypto.Cipher import DES, AES

    cipher = DES.new(SECRET_KEY)

    def send_encrypted(channel, message):
        channel.send(cipher.encrypt(message)) # BAD: weak encryption


    cipher = AES.new(SECRET_KEY)

    def send_encrypted(channel, message):
        channel.send(cipher.encrypt(message)) # GOOD: strong encryption


    ```
    NOTICE: the original `[pycrypto](https://pypi.org/project/pycrypto/)` PyPI package that provided the `Crypto` module is not longer actively maintained, so you should use the `[pycryptodome](https://pypi.org/project/pycryptodome/)` PyPI package instead (which has a compatible API).

    # Default version of SSL/TLS may be insecure
    The `ssl.wrap_socket` function defaults to an insecure version of SSL/TLS when no specific protocol version is specified. This may leave the connection vulnerable to attack.


    ## Recommendation
    Ensure that a modern, strong protocol is used. All versions of SSL, and TLS 1.0 and 1.1 are known to be vulnerable to attacks. Using TLS 1.2 or above is strongly recommended. If no explicit `ssl_version` is specified, the default `PROTOCOL_TLS` is chosen. This protocol is insecure because it allows TLS 1.0 and TLS 1.1 and so should not be used.


    ## Example
    The following code shows two different ways of setting up a connection using SSL or TLS. They are both potentially insecure because the default version is used.


    ```python
    import ssl
    import socket

    # Using the deprecated ssl.wrap_socket method
    ssl.wrap_socket(socket.socket())

    # Using SSLContext
    context = ssl.SSLContext()

    ```
    Both of the cases above should be updated to use a secure protocol instead, for instance by specifying `ssl_version=PROTOCOL_TLSv1_2` as a keyword argument.

    The latter example can also be made secure by modifying the created context before it is used to create a connection. Therefore it will not be flagged by this query. However, if a connection is created before the context has been secured (for example, by setting the value of `minimum_version`), then the code should be flagged by the query `py/insecure-protocol`.

    Note that `ssl.wrap_socket` has been deprecated in Python 3.7. The recommended alternatives are:

    * `ssl.SSLContext` - supported in Python 2.7.9, 3.2, and later versions
    * `ssl.create_default_context` - a convenience function, supported in Python 3.4 and later versions.
    Even when you use these alternatives, you should ensure that a safe protocol is used. The following code illustrates how to use flags (available since Python 3.2) or the \`minimum_version\` field (favored since Python 3.7) to restrict the protocols accepted when creating a connection.


    ```python
    import ssl

    # Using flags to restrict the protocol
    context = ssl.SSLContext()
    context.options |= ssl.OP_NO_TLSv1 | ssl.OP_NO_TLSv1_1

    # Declaring a minimum version to restrict the protocol
    context = ssl.create_default_context()
    context.minimum_version = ssl.TLSVersion.TLSv1_2

    ```

    # Use of insecure SSL/TLS version
    Using a broken or weak cryptographic protocol may make a connection vulnerable to interference from an attacker.


    ## Recommendation
    Ensure that a modern, strong protocol is used. All versions of SSL, and TLS versions 1.0 and 1.1 are known to be vulnerable to attacks. Using TLS 1.2 or above is strongly recommended.


    ## Example
    The following code shows a variety of ways of setting up a connection using SSL or TLS. They are all insecure because of the version specified.


    ```python
    import ssl
    import socket

    # Using the deprecated ssl.wrap_socket method
    ssl.wrap_socket(socket.socket(), ssl_version=ssl.PROTOCOL_SSLv2)

    # Using SSLContext
    context = ssl.SSLContext(ssl_version=ssl.PROTOCOL_SSLv3)

    # Using pyOpenSSL

    from pyOpenSSL import SSL

    context = SSL.Context(SSL.TLSv1_METHOD)



    ```
    All cases should be updated to use a secure protocol, such as `PROTOCOL_TLSv1_2`.

    Note that `ssl.wrap_socket` has been deprecated in Python 3.7. The recommended alternatives are:

    * `ssl.SSLContext` - supported in Python 2.7.9, 3.2, and later versions

    context.minimum_version = ssl.TLSVersion.TLSv1_2

    # Use of a broken or weak cryptographic hashing algorithm on sensitive data
    Using a broken or weak cryptographic hash function can leave data vulnerable, and should not be used in security related code.

    A strong cryptographic hash function should be resistant to:

    * pre-image attacks: if you know a hash value `h(x)`, you should not be able to easily find the input `x`.
    * collision attacks: if you know a hash value `h(x)`, you should not be able to easily find a different input `y` with the same hash value `h(x) = h(y)`.
    In cases with a limited input space, such as for passwords, the hash function also needs to be computationally expensive to be resistant to brute-force attacks. Passwords should also have an unique salt applied before hashing, but that is not considered by this query.

    As an example, both MD5 and SHA-1 are known to be vulnerable to collision attacks.

    Since it's OK to use a weak cryptographic hash function in a non-security context, this query only alerts when these are used to hash sensitive data (such as passwords, certificates, usernames).

    Use of broken or weak cryptographic algorithms that are not hashing algorithms, is handled by the `py/weak-cryptographic-algorithm` query.


    ## Recommendation
    Ensure that you use a strong, modern cryptographic hash function:

    * such as Argon2, scrypt, bcrypt, or PBKDF2 for passwords and other data with limited input space.
    * such as SHA-2, or SHA-3 in other cases.

    ## Example
    The following example shows two functions for checking whether the hash of a certificate matches a known value -- to prevent tampering. The first function uses MD5 that is known to be vulnerable to collision attacks. The second function uses SHA-256 that is a strong cryptographic hashing function.


    ```python
    import hashlib

    def certificate_matches_known_hash_bad(certificate, known_hash):
        hash = hashlib.md5(certificate).hexdigest() # BAD
        return hash == known_hash

    def certificate_matches_known_hash_good(certificate, known_hash):
        hash = hashlib.sha256(certificate).hexdigest() # GOOD
        return hash == known_hash

    ```

    ## Example
    The following example shows two functions for hashing passwords. The first function uses SHA-256 to hash passwords. Although SHA-256 is a strong cryptographic hash function, it is not suitable for password hashing since it is not computationally expensive.


    ```python
    import hashlib

    def get_password_hash(password: str, salt: str):
        return hashlib.sha256(password + salt).hexdigest() # BAD

    ```
    The second function uses Argon2 (through the `argon2-cffi` PyPI package), which is a strong password hashing algorithm (and includes a per-password salt by default).


    ```python
    from argon2 import PasswordHasher

    def get_initial_hash(password: str):
        ph = PasswordHasher()
        return ph.hash(password) # GOOD

    def check_password(password: str, known_hash):
        ph = PasswordHasher()
        return ph.verify(known_hash, password) # GOOD

    ```

    # CSRF protection weakened or disabled
    Cross-site request forgery (CSRF) is a type of vulnerability in which an attacker is able to force a user to carry out an action that the user did not intend.

    The attacker tricks an authenticated user into submitting a request to the web application. Typically this request will result in a state change on the server, such as changing the user's password. The request can be initiated when the user visits a site controlled by the attacker. If the web application relies only on cookies for authentication, or on other credentials that are automatically included in the request, then this request will appear as legitimate to the server.

    A common countermeasure for CSRF is to generate a unique token to be included in the HTML sent from the server to a user. This token can be used as a hidden field to be sent back with requests to the server, where the server can then check that the token is valid and associated with the relevant user session.


    ## Recommendation
    In many web frameworks, CSRF protection is enabled by default. In these cases, using the default configuration is sufficient to guard against most CSRF attacks.


    ## Example
    The following example shows a case where CSRF protection is disabled by overriding the default middleware stack and not including the one protecting against CSRF.


    ```python
    MIDDLEWARE = [
        'django.middleware.security.SecurityMiddleware',
        'django.contrib.sessions.middleware.SessionMiddleware',
        'django.middleware.common.CommonMiddleware',
        # 'django.middleware.csrf.CsrfViewMiddleware',
        'django.contrib.auth.middleware.AuthenticationMiddleware',
        'django.contrib.messages.middleware.MessageMiddleware',
        'django.middleware.clickjacking.XFrameOptionsMiddleware',
    ]

    ```
    The protecting middleware was probably commented out during a testing phase, when server-side token generation was not set up. Simply commenting it back in will enable CSRF protection.

    # Insecure temporary file
    Functions that create temporary file names (such as `tempfile.mktemp` and `os.tempnam`) are fundamentally insecure, as they do not ensure exclusive access to a file with the temporary name they return. The file name returned by these functions is guaranteed to be unique on creation but the file must be opened in a separate operation. There is no guarantee that the creation and open operations will happen atomically. This provides an opportunity for an attacker to interfere with the file before it is opened.

    Note that `mktemp` has been deprecated since Python 2.3.


    ## Recommendation
    Replace the use of `mktemp` with some of the more secure functions in the `tempfile` module, such as `TemporaryFile`. If the file is intended to be accessed from other processes, consider using the `NamedTemporaryFile` function.


    ## Example
    The following piece of code opens a temporary file and writes a set of results to it. Because the file name is created using `mktemp`, another process may access this file before it is opened using `open`.


    ```python
    from tempfile import mktemp

    def write_results(results):
        filename = mktemp()
        with open(filename, "w+") as f:
            f.write(results)
        print("Results written to", filename)

    ```
    By changing the code to use `NamedTemporaryFile` instead, the file is opened immediately.


    ```python
    from tempfile import NamedTemporaryFile

    def write_results(results):
        with NamedTemporaryFile(mode="w+", delete=False) as f:
            f.write(results)
        print("Results written to", f.name)

    ```

    # Deserialization of user-controlled data
    Deserializing untrusted data using any deserialization framework that allows the construction of arbitrary serializable objects is easily exploitable and in many cases allows an attacker to execute arbitrary code. Even before a deserialized object is returned to the caller of a deserialization method a lot of code may have been executed, including static initializers, constructors, and finalizers. Automatic deserialization of fields means that an attacker may craft a nested combination of objects on which the executed initialization code may have unforeseen effects, such as the execution of arbitrary code.

    There are many different serialization frameworks. This query currently supports Pickle, Marshal and Yaml.


    ## Recommendation
    Avoid deserialization of untrusted data if at all possible. If the architecture permits it then use other formats instead of serialized objects, for example JSON.

    If you need to use YAML, use the `yaml.safe_load` function.


    ## Example
    The following example calls `pickle.loads` directly on a value provided by an incoming HTTP request. Pickle then creates a new value from untrusted data, and is therefore inherently unsafe.


    ```python

    from django.conf.urls import url
    import pickle

    def unsafe(pickled):
        return pickle.loads(pickled)

    urlpatterns = [
        url(r'^(?P<object>.*)$', unsafe)
    ]
    ```
    Changing the code to use `json.loads` instead of `pickle.loads` removes the vulnerability.


    ```python

    from django.conf.urls import url
    import json

    def safe(pickled):
        return json.loads(pickled)

    urlpatterns = [
        url(r'^(?P<object>.*)$', safe)
    ]

    ```

    # URL redirection from remote source
    Directly incorporating user input into a URL redirect request without validating the input can facilitate phishing attacks. In these attacks, unsuspecting users can be redirected to a malicious site that looks very similar to the real site they intend to visit, but which is controlled by the attacker.


    ## Recommendation
    To guard against untrusted URL redirection, it is advisable to avoid putting user input directly into a redirect URL. Instead, maintain a list of authorized redirects on the server; then choose from that list based on the user input provided.

    If this is not possible, then the user input should be validated in some other way, for example, by verifying that the target URL does not include an explicit host name.


    ## Example
    The following example shows an HTTP request parameter being used directly in a URL redirect without validating the input, which facilitates phishing attacks:


    ```python
    from flask import Flask, request, redirect

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        return redirect(target, code=302)

    ```
    If you know the set of valid redirect targets, you can maintain a list of them on the server and check that the user input is in that list:


    ```python
    from flask import Flask, request, redirect

    VALID_REDIRECT = "http://cwe.mitre.org/data/definitions/601.html"

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        if target == VALID_REDIRECT:
            return redirect(target, code=302)
        else:
            # ignore the target and redirect to the home page
            return redirect('/', code=302)

    ```
    Often this is not possible, so an alternative is to check that the target URL does not specify an explicit host name. For example, you can use the `urlparse` function from the Python standard library to parse the URL and check that the `netloc` attribute is empty.

    Note, however, that some cases are not handled as we desire out-of-the-box by `urlparse`, so we need to adjust two things, as shown in the example below:

    * Many browsers accept backslash characters (`\`) as equivalent to forward slash characters (`/`) in URLs, but the `urlparse` function does not.
    * Mistyped URLs such as `https:/example.com` or `https:///example.com` are parsed as having an empty `netloc` attribute, while browsers will still redirect to the correct site.

    ```python
    from flask import Flask, request, redirect
    from urllib.parse import urlparse

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        target = target.replace('\\', '')
        if not urlparse(target).netloc and not urlparse(target).scheme:
            # relative path, safe to redirect
            return redirect(target, code=302)
        # ignore the target and redirect to the home page
        return redirect('/', code=302)

    ```
    For Django application, you can use the function `url_has_allowed_host_and_scheme` to check that a URL is safe to redirect to, as shown in the following example:


    ```python
    from django.http import HttpResponseRedirect
    from django.shortcuts import redirect
    from django.utils.http import url_has_allowed_host_and_scheme
    from django.views import View

    class RedirectView(View):
        def get(self, request, *args, **kwargs):
            target = request.GET.get('target', '')
            if url_has_allowed_host_and_scheme(target, allowed_hosts=None):
                return HttpResponseRedirect(target)
            else:
                # ignore the target and redirect to the home page
                return redirect('/')
    ```
    Note that `url_has_allowed_host_and_scheme` handles backslashes correctly, so no additional processing is required.

    # XML external entity expansion
    Parsing untrusted XML files with a weakly configured XML parser may lead to an XML External Entity (XXE) attack. This type of attack uses external entity references to access arbitrary files on a system, carry out denial-of-service (DoS) attacks, or server-side request forgery. Even when the result of parsing is not returned to the user, DoS attacks are still possible and out-of-band data retrieval techniques may allow attackers to steal sensitive data.


    ## Recommendation
    The easiest way to prevent XXE attacks is to disable external entity handling when parsing untrusted data. How this is done depends on the library being used. Note that some libraries, such as recent versions of the XML libraries in the standard library of Python 3, disable entity expansion by default, so unless you have explicitly enabled entity expansion, no further action needs to be taken.

    We recommend using the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package, which has been created to prevent XML attacks (both XXE and XML bombs).


    ## Example
    The following example uses the `lxml` XML parser to parse a string `xml_src`. That string is from an untrusted source, so this code is vulnerable to an XXE attack, since the [ default parser](https://lxml.de/apidoc/lxml.etree.html#lxml.etree.XMLParser) from `lxml.etree` allows local external entities to be resolved.


    ```python
    from flask import Flask, request
    import lxml.etree

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = lxml.etree.fromstring(xml_src)
        return lxml.etree.tostring(doc)

    ```
    To guard against XXE attacks with the `lxml` library, you should create a parser with `resolve_entities` set to `false`. This means that no entity expansion is undertaken, although standard predefined entities such as `&gt;`, for writing `>` inside the text of an XML element, are still allowed.


    ```python
    from flask import Flask, request
    import lxml.etree

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        parser = lxml.etree.XMLParser(resolve_entities=False)
        doc = lxml.etree.fromstring(xml_src, parser=parser)
        return lxml.etree.tostring(doc)

    ```

    # XPath query built from user-controlled sources
    If an XPath expression is built using string concatenation, and the components of the concatenation include user input, it makes it very easy for a user to create a malicious XPath expression.


    ## Recommendation
    If user input must be included in an XPath expression, either sanitize the data or use variable references to safely embed it without altering the structure of the expression.


    ## Example
    In the example below, the xpath query is controlled by the user and hence leads to a vulnerability.


    ```python
    from lxml import etree
    from io import StringIO

    from django.urls import path
    from django.http import HttpResponse
    from django.template import Template, Context, Engine, engines


    def a(request):
        value = request.GET['xpath']
        f = StringIO('<foo><bar></bar></foo>')
        tree = etree.parse(f)
        r = tree.xpath("/tag[@id='%s']" % value)


    urlpatterns = [
        path('a', a)
    ]

    ```
    This can be fixed by using a parameterized query as shown below.


    ```python
    from lxml import etree
    from io import StringIO

    from django.urls import path
    from django.http import HttpResponse
    from django.template import Template, Context, Engine, engines


    def a(request):
        value = request.GET['xpath']
        f = StringIO('<foo><bar></bar></foo>')
        tree = etree.parse(f)
        r = tree.xpath("/tag[@id=$tagid]", tagid=value)


    urlpatterns = [
        path('a', a)
    ]

    ```

    \ or even allow a malicious user to perform a Denial of Service (\"DoS\") attack\
    \ by crafting an expensive input string for the regular expression to match.\n\
    \nThe regular expression engine provided by Python uses a backtracking non-deterministic\
    \ finite automata to implement regular expression matching. While this approach\
    \ is space-efficient and allows supporting advanced features like capture groups,\
    \ it is not time-efficient in general. The worst-case time complexity of such\

    \ of a certain shape, increasing the input length by ten characters may make the\
    \ automaton about 1000 times slower.\n\nTypically, a regular expression is affected\
    \ by this problem if it contains a repetition of the form `r*` or `r+` where the\
    \ sub-expression `r` is ambiguous in the sense that it can match some string in\
    \ multiple ways. More information about the precise circumstances can be found\
    \ in the references.\n\n\n## Recommendation\nModify the regular expression to\
    \ remove the ambiguity, or ensure that the strings matched with the regular expression\
    \ are short enough that the time-complexity does not matter.\n\n\n## Example\n\
    Consider this use of a regular expression, which removes all leading and trailing\
    \ whitespace in a string:\n\n```python\n\nre.sub(r\"^\\s+|\\s+$\", \"\", text)\
    \ # BAD\n```\nThe sub-expression `\"\\s+$\"` will match the whitespace characters\
    \ in `text` from left to right, but it can start matching anywhere within a whitespace\
    \ sequence. This is problematic for strings that do **not** end with a whitespace\
    \ character. Such a string will force the regular expression engine to process\
    \ each whitespace sequence once per whitespace character in the sequence.\n\n\
    This ultimately means that the time cost of trimming a string is quadratic in\
    \ the length of the string. So a string like `\"a b\"` will take milliseconds\
    \ to process, but a similar string with a million spaces instead of just one will\
    \ take several minutes.\n\nAvoid this problem by rewriting the regular expression\
    \ to not contain the ambiguity about when to start matching whitespace sequences.\
    \ For instance, by using a negative look-behind (`^\\s+|(?<!\\s)\\s+$`), or just\
    \ by using the built-in strip method (`text.strip()`).\n\nNote that the sub-expression\
    \ `\"^\\s+\"` is **not** problematic as the `^` anchor restricts when that sub-expression\
    \ can start matching, and as the regular expression engine matches from left to\
    \ right.\n\n\n## Example\nAs a similar, but slightly subtler problem, consider\
    \ the regular expression that matches lines with numbers, possibly written using\
    \ scientific notation:\n\n```python\n\n^0\\.\\d+E?\\d+$ # BAD\n```\nThe problem\
    \ with this regular expression is in the sub-expression `\\d+E?\\d+` because the\
    \ second `\\d+` can start matching digits anywhere after the first match of the\
    \ first `\\d+` if there is no `E` in the input string.\n\nThis is problematic\
    \ for strings that do **not** end with a digit. Such a string will force the regular\
    \ expression engine to process each digit sequence once per digit in the sequence,\
    \ again leading to a quadratic time complexity.\n\nTo make the processing faster,\
    \ the regular expression should be rewritten such that the two `\\d+` sub-expressions\
    \ do not have overlapping matches: `^0\\.\\d+(E\\d+)?$`.\n\n\n## Example\nSometimes\
    \ it is unclear how a regular expression can be rewritten to avoid the problem.\
    \ In such cases, it often suffices to limit the length of the input string. For\
    \ instance, the following regular expression is used to match numbers, and on\
    \ some non-number inputs it can have quadratic time complexity:\n\n```python\n\
    \nmatch = re.search(r'^(\\+|-)?(\\d+|(\\d*\\.\\d*))?(E|e)?([-+])?(\\d+)?$', str)\
    \ \n```\nIt is not immediately obvious how to rewrite this regular expression\
    \ to avoid the problem. However, you can mitigate performance issues by limiting\
    \ the length to 1000 characters, which will always finish in a reasonable amount\
    \ of time.\n\n```python\n\nif len(str) > 1000:\n    raise ValueError(\"Input too\
    \ long\")\n\nmatch = re.search(r'^(\\+|-)?(\\d+|(\\d*\\.\\d*))?(E|e)?([-+])?(\\\
    d+)?$', str) \n```\n\n## References\n* OWASP: [Regular expression Denial of Service\

    ```
    Its sub-expression `"(__|.)+?"` can match the string `"__"` either by the first alternative `"__"` to the left of the `"|"` operator, or by two repetitions of the second alternative `"."` to the right. Thus, a string consisting of an odd number of underscores followed by some other character will cause the regular expression engine to run for an exponential amount of time before rejecting the input.

    This problem can be avoided by rewriting the regular expression to remove the ambiguity between the two branches of the alternative inside the repetition:

    ```python

    ^_(__|[^_])+_$
    ```

    # Regular expression injection
    Constructing a regular expression with unsanitized user input is dangerous as a malicious user may be able to modify the meaning of the expression. In particular, such a user may be able to provide a regular expression fragment that takes exponential time in the worst case, and use that to perform a Denial of Service attack.


    ## Recommendation
    Before embedding user input into a regular expression, use a sanitization function such as `re.escape` to escape meta-characters that have a special meaning regarding regular expressions' syntax.


    ## Example
    The following examples are based on a simple Flask web server environment.

    The following example shows a HTTP request parameter that is used to construct a regular expression without sanitizing it first:


    ```python
    from flask import request, Flask
    import re


    @app.route("/direct")
    def direct():
        unsafe_pattern = request.args["pattern"]
        re.search(unsafe_pattern, "")


    @app.route("/compile")
    def compile():
        unsafe_pattern = request.args["pattern"]
        compiled_pattern = re.compile(unsafe_pattern)
        compiled_pattern.search("")

    ```
    Instead, the request parameter should be sanitized first, for example using the function `re.escape`. This ensures that the user cannot insert characters which have a special meaning in regular expressions.


    ```python
    from flask import request, Flask
    import re


    @app.route("/direct")
    def direct():
        unsafe_pattern = request.args['pattern']
        safe_pattern = re.escape(unsafe_pattern)
        re.search(safe_pattern, "")


    @app.route("/compile")
    def compile():
        unsafe_pattern = request.args['pattern']
        safe_pattern = re.escape(unsafe_pattern)
        compiled_pattern = re.compile(safe_pattern)
        compiled_pattern.search("")

    ```

    # XML internal entity expansion
    Parsing untrusted XML files with a weakly configured XML parser may be vulnerable to denial-of-service (DoS) attacks exploiting uncontrolled internal entity expansion.

    In XML, so-called *internal entities* are a mechanism for introducing an abbreviation for a piece of text or part of a document. When a parser that has been configured to expand entities encounters a reference to an internal entity, it replaces the entity by the data it represents. The replacement text may itself contain other entity references, which are expanded recursively. This means that entity expansion can increase document size dramatically.

    If untrusted XML is parsed with entity expansion enabled, a malicious attacker could submit a document that contains very deeply nested entity definitions, causing the parser to take a very long time or use large amounts of memory. This is sometimes called an *XML bomb* attack.


    ## Recommendation
    The safest way to prevent XML bomb attacks is to disable entity expansion when parsing untrusted data. Whether this can be done depends on the library being used. Note that some libraries, such as `lxml`, have measures enabled by default to prevent such DoS XML attacks, so unless you have explicitly set `huge_tree` to `True`, no further action is needed.

    We recommend using the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package, which has been created to prevent XML attacks (both XXE and XML bombs).


    ## Example
    The following example uses the `xml.etree` XML parser provided by the Python standard library to parse a string `xml_src`. That string is from an untrusted source, so this code is vulnerable to a DoS attack, since the `xml.etree` XML parser expands internal entities by default:


    ```python
    from flask import Flask, request
    import xml.etree.ElementTree as ET

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = ET.fromstring(xml_src)
        return ET.tostring(doc)

    ```
    It is not possible to guard against internal entity expansion with `xml.etree`, so to guard against these attacks, the following example uses the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package instead, which is not exposed to such internal entity expansion attacks.


    ```python
    from flask import Flask, request
    import defusedxml.ElementTree as ET

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = ET.fromstring(xml_src)
        return ET.tostring(doc)

    ```

    # Full server-side request forgery
    Directly incorporating user input into an HTTP request without validating the input can facilitate server-side request forgery (SSRF) attacks. In these attacks, the request may be changed, directed at a different server, or via a different protocol. This can allow the attacker to obtain sensitive information or perform actions with escalated privilege.

    We make a distinctions between how much of the URL an attacker can control:

    * **Full SSRF**: where the full URL can be controlled.
    * **Partial SSRF**: where only part of the URL can be controlled, such as the path component of a URL to a hardcoded domain.


    Partial control of a URL is often much harder to exploit. Therefore we have created a separate query for each of these.

    This query covers full SSRF, to find partial SSRF use the `py/partial-ssrf` query.


    ## Recommendation
    To guard against SSRF attacks you should avoid putting user-provided input directly into a request URL. On the application level, maintain a list of authorized URLs on the server and choose from that list based on the input provided. If that is not possible, one should verify the IP address for all user-controlled requests to ensure they are not private. This requires saving the verified IP address of each domain, then utilizing a custom HTTP adapter to ensure that future requests to that domain use the verified IP address. On the network level, you can segment the vulnerable application into its own LAN or block access to specific devices.


    ## Example
    The following example shows code vulnerable to a full SSRF attack, because it uses untrusted input (HTTP request parameter) directly to construct a URL. By using `evil.com#` as the `target` value, the requested URL will be `https://evil.com#.example.com/data/`. It also shows how to remedy the problem by using the user input select a known fixed string.


    ```python
    import requests
    from flask import Flask, request

    app = Flask(__name__)

    @app.route("/full_ssrf")
    def full_ssrf():
        target = request.args["target"]

        # BAD: user has full control of URL
        resp = requests.get("https://" + target + ".example.com/data/")

        # GOOD: `subdomain` is controlled by the server.
        subdomain = "europe" if target == "EU" else "world"
        resp = requests.get("https://" + subdomain + ".example.com/data/")

    ```

    ## Example
    The following example shows code vulnerable to a partial SSRF attack, because it uses untrusted input (HTTP request parameter) directly to construct a URL. By using `../transfer-funds-to/123?amount=456` as the `user_id` value, the requested URL will be `https://api.example.com/transfer-funds-to/123?amount=456`. It also shows how to remedy the problem by validating the input.


    ```python
    import requests
    from flask import Flask, request

    app = Flask(__name__)

    @app.route("/partial_ssrf")
    def partial_ssrf():
        user_id = request.args["user_id"]

        # BAD: user can fully control the path component of the URL
        resp = requests.get("https://api.example.com/user_info/" + user_id)

        if user_id.isalnum():
            # GOOD: user_id is restricted to be alpha-numeric, and cannot alter path component of URL
            resp = requests.get("https://api.example.com/user_info/" + user_id)

    ```

    # NoSQL Injection
    Passing user-controlled sources into NoSQL queries can result in a NoSQL injection flaw. This tainted NoSQL query containing a user-controlled source can then execute a malicious query in a NoSQL database such as MongoDB. In order for the user-controlled source to taint the NoSQL query, the user-controller source must be converted into a Python object using something like `json.loads` or `xmltodict.parse`.

    Because a user-controlled source is passed into the query, the malicious user can have complete control over the query itself. When the tainted query is executed, the malicious user can commit malicious actions such as bypassing role restrictions or accessing and modifying restricted data in the NoSQL database.


    ## Recommendation
    NoSQL injections can be prevented by escaping user-input's special characters that are passed into the NoSQL query from the user-supplied source. Alternatively, using a sanitize library such as MongoSanitizer will ensure that user-supplied sources can not act as a malicious query.


    ## Example
    In the example below, the user-supplied source is passed to a MongoDB function that queries the MongoDB database.


    ```python
    from flask import Flask, request
    from flask_pymongo import PyMongo
    import json

    mongo = PyMongo(app)


    @app.route("/")
    def home_page():
        unsanitized_search = request.args['search']
        json_search = json.loads(unsanitized_search)

        result = mongo.db.user.find({'name': json_search})

    ```
    This can be fixed by using a sanitizer library like MongoSanitizer as shown in this annotated code version below.


    ```python
    from flask import Flask, request
    from flask_pymongo import PyMongo
    from mongosanitizer.sanitizer import sanitize
    import json

    mongo = PyMongo(app)


    @app.route("/")
    def home_page():
        unsafe_search = request.args['search']
        json_search = json.loads(unsafe_search)
        safe_search = sanitize(unsanitized_search)

        result = client.db.collection.find_one({'data': safe_search})

    ```

    # 'input' function used in Python 2
    In Python 2, a call to the `input()` function, `input(prompt)` is equivalent to `eval(raw_input(prompt))`. Evaluating user input without any checking can be a serious security flaw.


    ## Recommendation
    Get user input with `raw_input(prompt)` and then validate that input before evaluating. If the expected input is a number or string, then `ast.literal_eval()` can always be used safely.

    # Binding a socket to all network interfaces
    Sockets can be used to communicate with other machines on a network. You can use the (IP address, port) pair to define the access restrictions for the socket you create. When using the built-in Python `socket` module (for instance, when building a message sender service or an FTP server data transmitter), one has to bind the port to some interface. When you bind the port to all interfaces using `0.0.0.0` as the IP address, you essentially allow it to accept connections from any IPv4 address provided that it can get to the socket via routing. Binding to all interfaces is therefore associated with security risks.


    ## Recommendation
    Bind your service incoming traffic only to a dedicated interface. If you need to bind more than one interface using the built-in `socket` module, create multiple sockets (instead of binding to one socket to all interfaces).


    ## Example
    In this example, two sockets are insecure because they are bound to all interfaces; one through the `0.0.0.0` notation and another one through an empty string `''`.


    ```python
    import socket

    # binds to all interfaces, insecure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('0.0.0.0', 31137))

    # binds to all interfaces, insecure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('', 4040))

    # binds only to a dedicated interface, secure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('84.68.10.12', 8080))

    ```

    # Construction of a cookie using user-supplied input
    Constructing cookies from user input can allow an attacker to control a user's cookie. This may lead to a session fixation attack. Additionally, client code may not expect a cookie to contain attacker-controlled data, and fail to sanitize it for common vulnerabilities such as Cross Site Scripting (XSS). An attacker manipulating the raw cookie header may additionally be able to set cookie attributes such as `HttpOnly` to insecure values.


    ## Recommendation
    Do not use raw user input to construct cookies.


    ## Example
    In the following cases, a cookie is constructed for a Flask response using user input. The first uses `set_cookie`, and the second sets a cookie's raw value through the `set-cookie` header.


    ```python
    from flask import request, make_response


    @app.route("/1")
    def set_cookie():
        resp = make_response()
        resp.set_cookie(request.args["name"], # BAD: User input is used to set the cookie's name and value
                        value=request.args["name"])
        return resp


    @app.route("/2")
    def set_cookie_header():
        resp = make_response()
        resp.headers['Set-Cookie'] = f"{request.args['name']}={request.args['name']};" # BAD: User input is used to set the raw cookie header.
        return resp

    ```

    # Incomplete regular expression for hostnames
    Sanitizing untrusted URLs is a common technique for preventing attacks such as request forgeries and malicious redirections. Often, this is done by checking that the host of a URL is in a set of allowed hosts.

    If a regular expression implements such a check, it is easy to accidentally make the check too permissive by not escaping the `.` meta-characters appropriately. Even if the check is not used in a security-critical context, the incomplete check may still cause undesirable behaviors when it accidentally succeeds.


    ## Recommendation
    Escape all meta-characters appropriately when constructing regular expressions for security checks, and pay special attention to the `.` meta-character.


    ## Example
    The following example code checks that a URL redirection will reach the `example.com` domain, or one of its subdomains.


    ```python
    from flask import Flask, request, redirect
    import re

    app = Flask(__name__)

    UNSAFE_REGEX = re.compile("(www|beta).example.com/")
    SAFE_REGEX = re.compile(r"(www|beta)\.example\.com/")

    @app.route('/some/path/bad')
    def unsafe(request):
        target = request.args.get('target', '')
        if UNSAFE_REGEX.match(target):
            return redirect(target)

    @app.route('/some/path/good')
    def safe(request):
        target = request.args.get('target', '')
        if SAFE_REGEX.match(target):
            return redirect(target)

    ```
    The `unsafe` check is easy to bypass because the unescaped `.` allows for any character before `example.com`, effectively allowing the redirect to go to an attacker-controlled domain such as `wwwXexample.com`.

    The `safe` check closes this vulnerability by escaping the `.` so that URLs of the form `wwwXexample.com` are rejected.

    # Incomplete URL substring sanitization
    Sanitizing untrusted URLs is a common technique for preventing attacks such as request forgeries and malicious redirections. Usually, this is done by checking that the host of a URL is in a set of allowed hosts.

    However, treating the URL as a string and checking if one of the allowed hosts is a substring of the URL is very prone to errors. Malicious URLs can bypass such security checks by embedding one of the allowed hosts in an unexpected location.

    Even if the substring check is not used in a security-critical context, the incomplete check may still cause undesirable behaviors when the check succeeds accidentally.


    ## Recommendation
    Parse a URL before performing a check on its host value, and ensure that the check handles arbitrary subdomain sequences correctly.


    ## Example
    The following example code checks that a URL redirection will reach the `example.com` domain.


    ```python
    from flask import Flask, request, redirect
    from urllib.parse import urlparse

    app = Flask(__name__)

    # Not safe, as "evil-example.net/example.com" would be accepted

    @app.route('/some/path/bad1')
    def unsafe1(request):
        target = request.args.get('target', '')
        if "example.com" in target:
            return redirect(target)

    # Not safe, as "benign-looking-prefix-example.com" would be accepted

    @app.route('/some/path/bad2')
    def unsafe2(request):
        target = request.args.get('target', '')
        if target.endswith("example.com"):
            return redirect(target)



    #Simplest and safest approach is to use an allowlist

    @app.route('/some/path/good1')
    def safe1(request):
        allowlist = [
            "example.com/home",
            "example.com/login",
        ]
        target = request.args.get('target', '')
        if target in allowlist:
            return redirect(target)

    #More complex example allowing sub-domains.

    @app.route('/some/path/good2')
    def safe2(request):
        target = request.args.get('target', '')
        host = urlparse(target).hostname
        #Note the '.' preceding example.com
        if host and host.endswith(".example.com"):
            return redirect(target)


    ```
    The first two examples show unsafe checks that are easily bypassed. In `unsafe1` the attacker can simply add `example.com` anywhere in the url. For example, `http://evil-example.net/example.com`.

    In `unsafe2` the attacker must use a hostname ending in `example.com`, but that is easy to do. For example, `http://benign-looking-prefix-example.com`.

    The second two examples show safe checks. In `safe1`, an allowlist is used. Although fairly inflexible, this is easy to get right and is most likely to be safe.

    In `safe2`, `urlparse` is used to parse the URL, then the hostname is checked to make sure it ends with `.example.com`.

    # Overly permissive regular expression range
    It's easy to write a regular expression range that matches a wider range of characters than you intended. For example, `/[a-zA-z]/` matches all lowercase and all uppercase letters, as you would expect, but it also matches the characters: `` [ \ ] ^ _ ` ``.

    Another common problem is failing to escape the dash character in a regular expression. An unescaped dash is interpreted as part of a range. For example, in the character class `[a-zA-Z0-9%=.,-_]` the last character range matches the 55 characters between `,` and `_` (both included), which overlaps with the range `[0-9]` and is clearly not intended by the writer.


    ## Recommendation
    Avoid any confusion about which characters are included in the range by writing unambiguous regular expressions. Always check that character ranges match only the expected characters.


    ## Example
    The following example code is intended to check whether a string is a valid 6 digit hex color.

    ```python

    import re
    def is_valid_hex_color(color):
        return re.match(r'^#[0-9a-fA-f]{6}$', color) is not None

    ```
    However, the `A-f` range is overly large and matches every uppercase character. It would parse a "color" like `#XXYYZZ` as valid.

    The fix is to use an uppercase `A-F` range instead.

    ```python

    import re

    # Uncontrolled data used in path expression
    Accessing files using paths constructed from user-controlled data can allow an attacker to access unexpected resources. This can result in sensitive information being revealed or deleted, or an attacker being able to influence behavior by modifying unexpected files.


    ## Recommendation
    Validate paths constructed from untrusted user input before using them to access files.

    The choice of validation depends on the use case.

    If you want to allow paths spanning multiple folders, a common strategy is to make sure that the constructed file path is contained within a safe root folder. First, normalize the path using `os.path.normpath` or `os.path.realpath` (make sure to use the latter if symlinks are a consideration) to remove any internal ".." segments and/or follow links. Then check that the normalized path starts with the root folder. Note that the normalization step is important, since otherwise even a path that starts with the root folder could be used to access files outside the root folder.

    More restrictive options include using a library function like `werkzeug.utils.secure_filename` to eliminate any special characters from the file path, or restricting the path to a known list of safe paths. These options are safe, but can only be used in particular circumstances.


    ## Example
    In the first example, a file name is read from an HTTP request and then used to access a file. However, a malicious user could enter a file name that is an absolute path, such as `"/etc/passwd"`.

    In the second example, it appears that the user is restricted to opening a file within the `"user"` home directory. However, a malicious user could enter a file name containing special characters. For example, the string `"../../../etc/passwd"` will result in the code reading the file located at `"/server/static/images/../../../etc/passwd"`, which is the system's password file. This file would then be sent back to the user, giving them access to all the system's passwords. Note that a user could also use an absolute path here, since the result of `os.path.join("/server/static/images/", "/etc/passwd")` is `"/etc/passwd"`.

    In the third example, the path used to access the file system is normalized *before* being checked against a known prefix. This ensures that regardless of the user input, the resulting path is safe.


    ```python
    import os.path
    from flask import Flask, request, abort

    app = Flask(__name__)

    @app.route("/user_picture1")
    def user_picture1():
        filename = request.args.get('p')
        # BAD: This could read any file on the file system
        data = open(filename, 'rb').read()
        return data

    @app.route("/user_picture2")
    def user_picture2():
        base_path = '/server/static/images'
        filename = request.args.get('p')
        # BAD: This could still read any file on the file system
        data = open(os.path.join(base_path, filename), 'rb').read()
        return data

    @app.route("/user_picture3")
    def user_picture3():
        base_path = '/server/static/images'
        filename = request.args.get('p')
        #GOOD -- Verify with normalised version of path
        fullpath = os.path.normpath(os.path.join(base_path, filename))
        if not fullpath.startswith(base_path):
            raise Exception("not allowed")
        data = open(fullpath, 'rb').read()
        return data

    ```

    # Arbitrary file write during tarfile extraction
    Extracting files from a malicious tar archive without validating that the destination file path is within the destination directory can cause files outside the destination directory to be overwritten, due to the possible presence of directory traversal elements (`..`) in archive paths.

    Tar archives contain archive entries representing each file in the archive. These entries include a file path for the entry, but these file paths are not restricted and may contain unexpected special elements such as the directory traversal element (`..`). If these file paths are used to determine an output file to write the contents of the archive item to, then the file may be written to an unexpected location. This can result in sensitive information being revealed or deleted, or an attacker being able to influence behavior by modifying unexpected files.

    For example, if a tar archive contains a file entry `..\sneaky-file`, and the tar archive is extracted to the directory `c:\output`, then naively combining the paths would result in an output file path of `c:\output\..\sneaky-file`, which would cause the file to be written to `c:\sneaky-file`.


    ## Recommendation
    Ensure that output paths constructed from tar archive entries are validated to prevent writing files to unexpected locations.

    The recommended way of writing an output file from a tar archive entry is to check that `".."` does not occur in the path.


    ## Example
    In this example an archive is extracted without validating file paths. If `archive.tar` contained relative paths (for instance, if it were created by something like `tar -cf archive.tar ../file.txt`) then executing this code could write to locations outside the destination directory.


    ```python
    import sys
    import tarfile

    with tarfile.open(sys.argv[1]) as tar:
        #BAD : This could write any file on the filesystem.
        for entry in tar:
            tar.extract(entry, "/tmp/unpack/")

    ```
    To fix this vulnerability, we need to check that the path does not contain any `".."` elements in it.


    ```python
    import sys
    import tarfile
    import os.path

    with tarfile.open(sys.argv[1]) as tar:
        for entry in tar:
            #GOOD: Check that entry is safe
            if os.path.isabs(entry.name) or ".." in entry.name:
                raise ValueError("Illegal tar archive entry")
            tar.extract(entry, "/tmp/unpack/")

    ```

    \ }}{% endif %}{% endfor %}\n\n```\nIn the following case, user input is not used\
    \ to construct the template. Instead, it is only used as the parameters to render\
    \ the template, which is safe.\n\n\n```python\nfrom django.urls import path\n\
    from django.http import HttpResponse\nfrom jinja2 import Template, escape\n\n\n\
    def a(request):\n    # GOOD: Template is a constant, not constructed from user\

    # Uncontrolled command line
    Code that passes user input directly to `exec`, `eval`, or some other library routine that executes a command, allows the user to execute malicious code.


    ## Recommendation
    If possible, use hard-coded string literals to specify the command to run or the library to load. Instead of passing the user input directly to the process or library function, examine the user input and then choose among hard-coded string literals.

    If the applicable libraries or commands cannot be determined at compile time, then add code to verify that the user input string is safe before using it.


    ## Example
    The following example shows two functions. The first is unsafe as it takes a shell script that can be changed by a user, and passes it straight to `subprocess.call()` without examining it first. The second is safe as it selects the command from a predefined allowlist.


    ```python

    urlpatterns = [
        # Route to command_execution
        url(r'^command-ex1$', command_execution_unsafe, name='command-execution-unsafe'),
        url(r'^command-ex2$', command_execution_safe, name='command-execution-safe')
    ]

    COMMANDS = {
        "list" :"ls",
        "stat" : "stat"
    }

    def command_execution_unsafe(request):
        if request.method == 'POST':
            action = request.POST.get('action', '')
            #BAD -- No sanitizing of input
            subprocess.call(["application", action])

    def command_execution_safe(request):
        if request.method == 'POST':
            action = request.POST.get('action', '')
            #GOOD -- Use an allowlist
            subprocess.call(["application", COMMANDS[action]])

    # Jinja2 templating with autoescape=False
    Cross-site scripting (XSS) attacks can occur if untrusted input is not escaped. This applies to templates as well as code. The `jinja2` templates may be vulnerable to XSS if the environment has `autoescape` set to `False`. Unfortunately, `jinja2` sets `autoescape` to `False` by default. Explicitly setting `autoescape` to `True` when creating an `Environment` object will prevent this.


    ## Recommendation
    Avoid setting jinja2 autoescape to False. Jinja2 provides the function `select_autoescape` to make sure that the correct auto-escaping is chosen. For example, it can be used when creating an environment `Environment(autoescape=select_autoescape(['html', 'xml'])`


    ## Example
    The following example is a minimal Flask app which shows a safe and an unsafe way to render the given name back to the page. The first view is unsafe as `first_name` is not escaped, leaving the page vulnerable to cross-site scripting attacks. The second view is safe as `first_name` is escaped, so it is not vulnerable to cross-site scripting attacks.


    ```python
    from flask import Flask, request, make_response, escape
    from jinja2 import Environment, select_autoescape, FileSystemLoader

    app = Flask(__name__)
    loader = FileSystemLoader( searchpath="templates/" )

    unsafe_env = Environment(loader=loader)
    safe1_env = Environment(loader=loader, autoescape=True)
    safe2_env = Environment(loader=loader, autoescape=select_autoescape())

    def render_response_from_env(env):
        name = request.args.get('name', '')
        template = env.get_template('template.html')
        return make_response(template.render(name=name))

    @app.route('/unsafe')
    def unsafe():
        return render_response_from_env(unsafe_env)

    @app.route('/safe1')

    # Reflected server-side cross-site scripting
    Directly writing user input (for example, an HTTP request parameter) to a webpage without properly sanitizing the input first, allows for a cross-site scripting vulnerability.


    ## Recommendation
    To guard against cross-site scripting, consider escaping the input before writing user input to the page. The standard library provides escaping functions: `html.escape()` for Python 3.2 upwards or `cgi.escape()` older versions of Python. Most frameworks also provide their own escaping functions, for example `flask.escape()`.


    ## Example
    The following example is a minimal flask app which shows a safe and unsafe way to render the given name back to the page. The first view is unsafe as `first_name` is not escaped, leaving the page vulnerable to cross-site scripting attacks. The second view is safe as `first_name` is escaped, so it is not vulnerable to cross-site scripting attacks.


    ```python
    from flask import Flask, request, make_response, escape

    app = Flask(__name__)

    @app.route('/unsafe')
    def unsafe():
        first_name = request.args.get('name', '')
        return make_response("Your name is " + first_name)

    @app.route('/safe')
    def safe():
        first_name = request.args.get('name', '')
        return make_response("Your name is " + escape(first_name))

    ```

    # SQL query built from user-controlled sources
    If a database query (such as a SQL or NoSQL query) is built from user-provided data without sufficient sanitization, a user may be able to run malicious database queries.

    This also includes using the `TextClause` class in the `[SQLAlchemy](https://pypi.org/project/SQLAlchemy/)` PyPI package, which is used to represent a literal SQL fragment and is inserted directly into the final SQL when used in a query built using the ORM.


    ## Recommendation
    Most database connector libraries offer a way of safely embedding untrusted data into a query by means of query parameters or prepared statements.


    ## Example
    In the following snippet, a user is fetched from the database using three different queries.

    In the first case, the query string is built by directly using string formatting from a user-supplied request parameter. The parameter may include quote characters, so this code is vulnerable to a SQL injection attack.

    In the second case, the user-supplied request attribute is passed to the database using query parameters. The database connector library will take care of escaping and inserting quotes as needed.

    In the third case, the placeholder in the SQL string has been manually quoted. Since most databaseconnector libraries will insert their own quotes, doing so yourself will make the code vulnerable to SQL injection attacks. In this example, if `username` was `; DROP ALL TABLES -- `, the final SQL query would be `SELECT * FROM users WHERE username = ''; DROP ALL TABLES -- ''`


    ```python
    from django.conf.urls import url
    from django.db import connection


    def show_user(request, username):
        with connection.cursor() as cursor:
            # BAD -- Using string formatting
            cursor.execute("SELECT * FROM users WHERE username = '%s'" % username)
            user = cursor.fetchone()

            # GOOD -- Using parameters
            cursor.execute("SELECT * FROM users WHERE username = %s", username)
            user = cursor.fetchone()

            # BAD -- Manually quoting placeholder (%s)
            cursor.execute("SELECT * FROM users WHERE username = '%s'", username)
            user = cursor.fetchone()

    urlpatterns = [url(r'^users/(?P<username>[^/]+)$', show_user)]

    ```

    # LDAP query built from user-controlled sources
    If an LDAP query or DN is built using string concatenation or string formatting, and the components of the concatenation include user input without any proper sanitization, a user is likely to be able to run malicious LDAP queries.


    ## Recommendation
    If user input must be included in an LDAP query or DN, it should be escaped to avoid a malicious user providing special characters that change the meaning of the query. In Python2, user input should be escaped with `ldap.dn.escape_dn_chars` or `ldap.filter.escape_filter_chars`, while in Python3, user input should be escaped with `ldap3.utils.dn.escape_rdn` or `ldap3.utils.conv.escape_filter_chars` depending on the component tainted by the user. A good practice is to escape filter characters that could change the meaning of the query (https://tools.ietf.org/search/rfc4515\#section-3).


    ## Example
    In the following examples, the code accepts both `username` and `dc` from the user, which it then uses to build a LDAP query and DN.

    The first and the second example uses the unsanitized user input directly in the search filter and DN for the LDAP query. A malicious user could provide special characters to change the meaning of these components, and search for a completely different set of values.


    ```python
    from flask import request, Flask
    import ldap


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        dn = "dc={}".format(unsafe_dc)
        search_filter = "(user={})".format(unsafe_filter)

        ldap_connection = ldap.initialize("ldap://127.0.0.1")
        user = ldap_connection.search_s(
            dn, ldap.SCOPE_SUBTREE, search_filter)

    ```

    ```python
    from flask import request, Flask
    import ldap3


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        dn = "dc={}".format(unsafe_dc)
        search_filter = "(user={})".format(unsafe_filter)

        srv = ldap3.Server('ldap://127.0.0.1')
        conn = ldap3.Connection(srv, user=dn, auto_bind=True)
        conn.search(dn, search_filter)

    ```
    In the third and fourth example, the input provided by the user is sanitized before it is included in the search filter or DN. This ensures the meaning of the query cannot be changed by a malicious user.


    ```python
    from flask import request, Flask
    import ldap
    import ldap.filter
    import ldap.dn


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        safe_dc = ldap.dn.escape_dn_chars(unsafe_dc)
        safe_filter = ldap.filter.escape_filter_chars(unsafe_filter)

        dn = "dc={}".format(safe_dc)
        search_filter = "(user={})".format(safe_filter)

        ldap_connection = ldap.initialize("ldap://127.0.0.1")
        user = ldap_connection.search_s(
            dn, ldap.SCOPE_SUBTREE, search_filter)

    ```

    ```python
    from flask import request, Flask
    import ldap3
    from ldap3.utils.dn import escape_rdn
    from ldap3.utils.conv import escape_filter_chars


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        safe_dc = escape_rdn(unsafe_dc)
        safe_filter = escape_filter_chars(unsafe_filter)

        dn = "dc={}".format(safe_dc)
        search_filter = "(user={})".format(safe_filter)

        srv = ldap3.Server('ldap://127.0.0.1')
        conn = ldap3.Connection(srv, user=dn, auto_bind=True)
        conn.search(dn, search_filter)

    ```

    # Code injection
    Directly evaluating user input (for example, an HTTP request parameter) as code without properly sanitizing the input first allows an attacker arbitrary code execution. This can occur when user input is passed to code that interprets it as an expression to be evaluated, such as `eval` or `exec`.


    ## Recommendation
    Avoid including user input in any expression that may be dynamically evaluated. If user input must be included, use context-specific escaping before including it. It is important that the correct escaping is used for the type of evaluation that will occur.


    ## Example
    The following example shows two functions setting a name from a request. The first function uses `exec` to execute the `setname` function. This is dangerous as it can allow a malicious user to execute arbitrary code on the server. For example, the user could supply the value `"' + subprocess.call('rm -rf') + '"` to destroy the server's file system. The second function calls the `setname` function directly and is thus safe.


    ```python

    urlpatterns = [
        # Route to code_execution
        url(r'^code-ex1$', code_execution_bad, name='code-execution-bad'),
        url(r'^code-ex2$', code_execution_good, name='code-execution-good')
    ]

    def code_execution(request):
        if request.method == 'POST':
            first_name = base64.decodestring(request.POST.get('first_name', ''))
            #BAD -- Allow user to define code to be run.
            exec("setname('%s')" % first_name)

    def code_execution(request):
        if request.method == 'POST':
            first_name = base64.decodestring(request.POST.get('first_name', ''))
            #GOOD --Call code directly
            setname(first_name)

    ```

    # Log Injection
    If unsanitized user input is written to a log entry, a malicious user may be able to forge new log entries.

    Forgery can occur if a user provides some input with characters that are interpreted when the log output is displayed. If the log is displayed as a plain text file, then new line characters can be used by a malicious user to create the appearance of multiple log entries. If the log is displayed as HTML, then arbitrary HTML may be included to spoof log entries.


    ## Recommendation
    User input should be suitably sanitized before it is logged.

    If the log entries are plain text then line breaks should be removed from user input, using for example `replace(old, new)` or similar. Care should also be taken that user input is clearly marked in log entries, and that a malicious user cannot cause confusion in other ways.

    For log entries that will be displayed in HTML, user input should be HTML encoded before being logged, to prevent forgery and other forms of HTML injection.


    ## Example
    In the example, the name provided by the user is recorded using the log output function (`logging.info` or `app.logger.info`, etc.). In these four cases, the name provided by the user is not provided The processing is recorded. If a malicious user provides `Guest%0D%0AUser name: Admin` as a parameter, the log entry will be divided into two lines, the first line is `User name: Guest` code&gt;, the second line is `User name: Admin`.

    ```
    In a good example, the program uses the `replace` function to provide parameter processing to the user, and replace `\r\n` and `\n` with empty characters. To a certain extent, the occurrence of log injection vulnerabilities is reduced.

    # Information exposure through an exception
    Software developers often add stack traces to error messages, as a debugging aid. Whenever that error message occurs for an end user, the developer can use the stack trace to help identify how to fix the problem. In particular, stack traces can tell the developer more about the sequence of events that led to a failure, as opposed to merely the final state of the software when the error occurred.

    Unfortunately, the same information can be useful to an attacker. The sequence of class names in a stack trace can reveal the structure of the application as well as any internal components it relies on. Furthermore, the error message at the top of a stack trace can include information such as server-side file names and SQL code that the application relies on, allowing an attacker to fine-tune a subsequent injection attack.


    ## Recommendation
    Send the user a more generic error message that reveals less information. Either suppress the stack trace entirely, or log it only on the server.


    ## Example
    In the following example, an exception is handled in two different ways. In the first version, labeled BAD, the exception is sent back to the remote user by returning it from the function. As such, the user is able to see a detailed stack trace, which may contain sensitive information. In the second version, the error message is logged only on the server, and a generic error message is displayed to the user. That way, the developers can still access and use the error log, but remote users will not see the information.


    ```python
    from flask import Flask
    app = Flask(__name__)


    import traceback

    def do_computation():
        raise Exception("Secret info")

    # BAD
    @app.route('/bad')
    def server_bad():
        try:
            do_computation()
        except Exception as e:
            return traceback.format_exc()

    # GOOD
    @app.route('/good')
    def server_good():
        try:
            do_computation()
        except Exception as e:
            log(traceback.format_exc())
            return "An internal error has occurred!"

    ```

    # PAM authorization bypass due to incorrect usage
    Using only a call to `pam_authenticate` to check the validity of a login can lead to authorization bypass vulnerabilities.

    A `pam_authenticate` only verifies the credentials of a user. It does not check if a user has an appropriate authorization to actually login. This means a user with an expired login or a password can still access the system.


    ## Recommendation
    A call to `pam_authenticate` should be followed by a call to `pam_acct_mgmt` to check if a user is allowed to login.


    ## Example
    In the following example, the code only checks the credentials of a user. Hence, in this case, a user with expired credentials can still login. This can be verified by creating a new user account, expiring it with ``` chage -E0 `username`  ``` and then trying to log in.


    ```python
    libpam                    = CDLL(find_library("pam"))

    pam_authenticate          = libpam.pam_authenticate
    pam_authenticate.restype  = c_int
    pam_authenticate.argtypes = [PamHandle, c_int]

    def authenticate(username, password, service='login'):
        def my_conv(n_messages, messages, p_response, app_data):
            """
            Simple conversation function that responds to any prompt where the echo is off with the supplied password
            """
            ...

        handle = PamHandle()
        conv   = PamConv(my_conv, 0)
        retval = pam_start(service, username, byref(conv), byref(handle))

        retval = pam_authenticate(handle, 0)
        return retval == 0

    ```
    This can be avoided by calling `pam_acct_mgmt` call to verify access as has been done in the snippet shown below.


    ```python
    libpam                    = CDLL(find_library("pam"))

    pam_authenticate          = libpam.pam_authenticate
    pam_authenticate.restype  = c_int
    pam_authenticate.argtypes = [PamHandle, c_int]

    pam_acct_mgmt          = libpam.pam_acct_mgmt
    pam_acct_mgmt.restype  = c_int
    pam_acct_mgmt.argtypes = [PamHandle, c_int]

    def authenticate(username, password, service='login'):
        def my_conv(n_messages, messages, p_response, app_data):
            """

            """
            ...

        handle = PamHandle()
        conv   = PamConv(my_conv, 0)
        retval = pam_start(service, username, byref(conv), byref(handle))

        retval = pam_authenticate(handle, 0)
        if retval == 0:
            retval = pam_acct_mgmt(handle, 0)
        return retval == 0

    # Accepting unknown SSH host keys when using Paramiko
    In the Secure Shell (SSH) protocol, host keys are used to verify the identity of remote hosts. Accepting unknown host keys may leave the connection open to man-in-the-middle attacks.


    ## Recommendation
    Do not accept unknown host keys. In particular, do not set the default missing host key policy for the Paramiko library to either `AutoAddPolicy` or `WarningPolicy`. Both of these policies continue even when the host key is unknown. The default setting of `RejectPolicy` is secure because it throws an exception when it encounters an unknown host key.


    ## Example
    The following example shows two ways of opening an SSH connection to `example.com`. The first function sets the missing host key policy to `AutoAddPolicy`. If the host key verification fails, the client will continue to interact with the server, even though the connection may be compromised. The second function sets the host key policy to `RejectPolicy`, and will throw an exception if the host key verification fails.


    ```python
    from paramiko.client import SSHClient, AutoAddPolicy, RejectPolicy

    def unsafe_connect():
        client = SSHClient()
        client.set_missing_host_key_policy(AutoAddPolicy)
        client.connect("example.com")

        # ... interaction with server

        client.close()

    def safe_connect():
        client = SSHClient()
        client.set_missing_host_key_policy(RejectPolicy)
        client.connect("example.com")

        # ... interaction with server

        client.close()

    ```

    # Request without certificate validation
    Encryption is key to the security of most, if not all, online communication. Using Transport Layer Security (TLS) can ensure that communication cannot be interrupted by an interloper. For this reason, it is unwise to disable the verification that TLS provides. Functions in the `requests` module provide verification by default, and it is only when explicitly turned off using `verify=False` that no verification occurs.


    ## Recommendation
    Never use `verify=False` when making a request.


    ## Example
    The example shows two unsafe calls to [semmle.com](https://semmle.com), followed by various safe alternatives.


    ```python
    import requests

    #Unsafe requests

    requests.get('https://semmle.com', verify=False) # UNSAFE
    requests.get('https://semmle.com', verify=0) # UNSAFE

    #Various safe options

    requests.get('https://semmle.com', verify=True) # Explicitly safe
    requests.get('https://semmle.com', verify="/path/to/cert/")
    requests.get('https://semmle.com') # The default is to verify.

    #Wrapper to ensure safety

    def make_safe_request(url, verify_cert):
        if not verify_cert:
            raise Exception("Trying to make unsafe request")
        return requests.get(url, verify_cert)

    # Clear-text logging of sensitive information
    If sensitive data is written to a log entry it could be exposed to an attacker who gains access to the logs.

    Potential attackers can obtain sensitive user data when the log output is displayed. Additionally that data may expose system information such as full path names, system information, and sometimes usernames and passwords.


    ## Recommendation
    Sensitive data should not be logged.


    ## Example
    In the example the entire process environment is logged using \`print\`. Regular users of the production deployed application should not have access to this much information about the environment configuration.


    ```python
    # BAD: Logging cleartext sensitive data
    import os
    print(f"[INFO] Environment: {os.environ}")
    ```
    In the second example the data that is logged is not sensitive.


    ```python
    not_sensitive_data = {'a': 1, 'b': 2}
    # GOOD: it is fine to log data that is not sensitive
    print(f"[INFO] Some object contains: {not_sensitive_data}")

    # Clear-text storage of sensitive information
    Sensitive information that is stored unencrypted is accessible to an attacker who gains access to the storage. This is particularly important for cookies, which are stored on the machine of the end-user.


    ## Recommendation
    Ensure that sensitive information is always encrypted before being stored. If possible, avoid placing sensitive information in cookies altogether. Instead, prefer storing, in the cookie, a key that can be used to look up the sensitive information.

    In general, decrypt sensitive information only at the point where it is necessary for it to be used in cleartext.

    Be aware that external processes often store the `standard out` and `standard error` streams of the application, causing logged sensitive information to be stored as well.


    ## Example
    The following example code stores user credentials (in this case, their password) in a cookie in plain text:


    ```python
    from flask import Flask, make_response, request

    app = Flask("Leak password")

    @app.route('/')
    def index():
        password = request.args.get("password")
        resp = make_response(render_template(...))
        resp.set_cookie("password", password)
        return resp

    ```
    Instead, the credentials should be encrypted, for instance by using the `cryptography` module, or not stored at all.

    # Use of weak cryptographic key
    Modern encryption relies on it being computationally infeasible to break the cipher and decode a message without the key. As computational power increases, the ability to break ciphers grows and keys need to become larger.

    The three main asymmetric key algorithms currently in use are Rivest–Shamir–Adleman (RSA) cryptography, Digital Signature Algorithm (DSA), and Elliptic-curve cryptography (ECC). With current technology, key sizes of 2048 bits for RSA and DSA, or 256 bits for ECC, are regarded as unbreakable.


    ## Recommendation
    Increase the key size to the recommended amount or larger. For RSA or DSA this is at least 2048 bits, for ECC this is at least 256 bits.

    # Use of a broken or weak cryptographic algorithm
    Using broken or weak cryptographic algorithms may compromise security guarantees such as confidentiality, integrity, and authenticity.

    Many cryptographic algorithms are known to be weak or flawed. The security guarantees of a system often rely on the underlying cryptography, so using a weak algorithm can have severe consequences. For example:

    * If a weak encryption algorithm is used, an attacker may be able to decrypt sensitive data.
    * If a weak algorithm is used for digital signatures, an attacker may be able to forge signatures and impersonate legitimate users.
    This query alerts on any use of a weak cryptographic algorithm that is not a hashing algorithm. Use of broken or weak cryptographic hash functions are handled by the `py/weak-sensitive-data-hashing` query.


    ## Recommendation
    Ensure that you use a strong, modern cryptographic algorithm, such as AES-128 or RSA-2048.


    ## Example
    The following code uses the `pycryptodome` library to encrypt some secret data. When you create a cipher using `pycryptodome` you must specify the encryption algorithm to use. The first example uses DES, which is an older algorithm that is now considered weak. The second example uses AES, which is a stronger modern algorithm.


    ```python
    from Crypto.Cipher import DES, AES

    cipher = DES.new(SECRET_KEY)

    def send_encrypted(channel, message):
        channel.send(cipher.encrypt(message)) # BAD: weak encryption


    cipher = AES.new(SECRET_KEY)

    def send_encrypted(channel, message):
        channel.send(cipher.encrypt(message)) # GOOD: strong encryption


    ```
    NOTICE: the original `[pycrypto](https://pypi.org/project/pycrypto/)` PyPI package that provided the `Crypto` module is not longer actively maintained, so you should use the `[pycryptodome](https://pypi.org/project/pycryptodome/)` PyPI package instead (which has a compatible API).

    # Default version of SSL/TLS may be insecure
    The `ssl.wrap_socket` function defaults to an insecure version of SSL/TLS when no specific protocol version is specified. This may leave the connection vulnerable to attack.


    ## Recommendation
    Ensure that a modern, strong protocol is used. All versions of SSL, and TLS 1.0 and 1.1 are known to be vulnerable to attacks. Using TLS 1.2 or above is strongly recommended. If no explicit `ssl_version` is specified, the default `PROTOCOL_TLS` is chosen. This protocol is insecure because it allows TLS 1.0 and TLS 1.1 and so should not be used.


    ## Example
    The following code shows two different ways of setting up a connection using SSL or TLS. They are both potentially insecure because the default version is used.


    ```python
    import ssl
    import socket

    # Using the deprecated ssl.wrap_socket method
    ssl.wrap_socket(socket.socket())

    # Using SSLContext
    context = ssl.SSLContext()

    ```
    Both of the cases above should be updated to use a secure protocol instead, for instance by specifying `ssl_version=PROTOCOL_TLSv1_2` as a keyword argument.

    The latter example can also be made secure by modifying the created context before it is used to create a connection. Therefore it will not be flagged by this query. However, if a connection is created before the context has been secured (for example, by setting the value of `minimum_version`), then the code should be flagged by the query `py/insecure-protocol`.

    Note that `ssl.wrap_socket` has been deprecated in Python 3.7. The recommended alternatives are:

    * `ssl.SSLContext` - supported in Python 2.7.9, 3.2, and later versions
    * `ssl.create_default_context` - a convenience function, supported in Python 3.4 and later versions.
    Even when you use these alternatives, you should ensure that a safe protocol is used. The following code illustrates how to use flags (available since Python 3.2) or the \`minimum_version\` field (favored since Python 3.7) to restrict the protocols accepted when creating a connection.


    ```python
    import ssl

    # Using flags to restrict the protocol
    context = ssl.SSLContext()
    context.options |= ssl.OP_NO_TLSv1 | ssl.OP_NO_TLSv1_1

    # Declaring a minimum version to restrict the protocol
    context = ssl.create_default_context()
    context.minimum_version = ssl.TLSVersion.TLSv1_2

    ```

    # Use of a broken or weak cryptographic hashing algorithm on sensitive data
    Using a broken or weak cryptographic hash function can leave data vulnerable, and should not be used in security related code.

    A strong cryptographic hash function should be resistant to:

    * pre-image attacks: if you know a hash value `h(x)`, you should not be able to easily find the input `x`.
    * collision attacks: if you know a hash value `h(x)`, you should not be able to easily find a different input `y` with the same hash value `h(x) = h(y)`.
    In cases with a limited input space, such as for passwords, the hash function also needs to be computationally expensive to be resistant to brute-force attacks. Passwords should also have an unique salt applied before hashing, but that is not considered by this query.

    As an example, both MD5 and SHA-1 are known to be vulnerable to collision attacks.

    Since it's OK to use a weak cryptographic hash function in a non-security context, this query only alerts when these are used to hash sensitive data (such as passwords, certificates, usernames).

    Use of broken or weak cryptographic algorithms that are not hashing algorithms, is handled by the `py/weak-cryptographic-algorithm` query.


    ## Recommendation
    Ensure that you use a strong, modern cryptographic hash function:

    * such as Argon2, scrypt, bcrypt, or PBKDF2 for passwords and other data with limited input space.
    * such as SHA-2, or SHA-3 in other cases.

    ## Example
    The following example shows two functions for checking whether the hash of a certificate matches a known value -- to prevent tampering. The first function uses MD5 that is known to be vulnerable to collision attacks. The second function uses SHA-256 that is a strong cryptographic hashing function.


    ```python
    import hashlib

    def certificate_matches_known_hash_bad(certificate, known_hash):
        hash = hashlib.md5(certificate).hexdigest() # BAD
        return hash == known_hash

    def certificate_matches_known_hash_good(certificate, known_hash):
        hash = hashlib.sha256(certificate).hexdigest() # GOOD
        return hash == known_hash

    ```

    ## Example
    The following example shows two functions for hashing passwords. The first function uses SHA-256 to hash passwords. Although SHA-256 is a strong cryptographic hash function, it is not suitable for password hashing since it is not computationally expensive.


    ```python
    import hashlib

    def get_password_hash(password: str, salt: str):
        return hashlib.sha256(password + salt).hexdigest() # BAD

    ```
    The second function uses Argon2 (through the `argon2-cffi` PyPI package), which is a strong password hashing algorithm (and includes a per-password salt by default).


    ```python
    from argon2 import PasswordHasher

    def get_initial_hash(password: str):
        ph = PasswordHasher()
        return ph.hash(password) # GOOD

    def check_password(password: str, known_hash):
        ph = PasswordHasher()
        return ph.verify(known_hash, password) # GOOD

    ```

    # CSRF protection weakened or disabled
    Cross-site request forgery (CSRF) is a type of vulnerability in which an attacker is able to force a user to carry out an action that the user did not intend.

    The attacker tricks an authenticated user into submitting a request to the web application. Typically this request will result in a state change on the server, such as changing the user's password. The request can be initiated when the user visits a site controlled by the attacker. If the web application relies only on cookies for authentication, or on other credentials that are automatically included in the request, then this request will appear as legitimate to the server.

    A common countermeasure for CSRF is to generate a unique token to be included in the HTML sent from the server to a user. This token can be used as a hidden field to be sent back with requests to the server, where the server can then check that the token is valid and associated with the relevant user session.


    ## Recommendation
    In many web frameworks, CSRF protection is enabled by default. In these cases, using the default configuration is sufficient to guard against most CSRF attacks.


    ## Example
    The following example shows a case where CSRF protection is disabled by overriding the default middleware stack and not including the one protecting against CSRF.


    ```python
    MIDDLEWARE = [
        'django.middleware.security.SecurityMiddleware',
        'django.contrib.sessions.middleware.SessionMiddleware',
        'django.middleware.common.CommonMiddleware',
        # 'django.middleware.csrf.CsrfViewMiddleware',
        'django.contrib.auth.middleware.AuthenticationMiddleware',
        'django.contrib.messages.middleware.MessageMiddleware',
        'django.middleware.clickjacking.XFrameOptionsMiddleware',
    ]

    ```
    The protecting middleware was probably commented out during a testing phase, when server-side token generation was not set up. Simply commenting it back in will enable CSRF protection.

    # Insecure temporary file
    Functions that create temporary file names (such as `tempfile.mktemp` and `os.tempnam`) are fundamentally insecure, as they do not ensure exclusive access to a file with the temporary name they return. The file name returned by these functions is guaranteed to be unique on creation but the file must be opened in a separate operation. There is no guarantee that the creation and open operations will happen atomically. This provides an opportunity for an attacker to interfere with the file before it is opened.

    Note that `mktemp` has been deprecated since Python 2.3.


    ## Recommendation
    Replace the use of `mktemp` with some of the more secure functions in the `tempfile` module, such as `TemporaryFile`. If the file is intended to be accessed from other processes, consider using the `NamedTemporaryFile` function.


    ## Example
    The following piece of code opens a temporary file and writes a set of results to it. Because the file name is created using `mktemp`, another process may access this file before it is opened using `open`.


    ```python
    from tempfile import mktemp

    def write_results(results):
        filename = mktemp()
        with open(filename, "w+") as f:
            f.write(results)
        print("Results written to", filename)

    ```
    By changing the code to use `NamedTemporaryFile` instead, the file is opened immediately.


    ```python
    from tempfile import NamedTemporaryFile

    def write_results(results):
        with NamedTemporaryFile(mode="w+", delete=False) as f:
            f.write(results)
        print("Results written to", f.name)

    ```

    # Deserialization of user-controlled data
    Deserializing untrusted data using any deserialization framework that allows the construction of arbitrary serializable objects is easily exploitable and in many cases allows an attacker to execute arbitrary code. Even before a deserialized object is returned to the caller of a deserialization method a lot of code may have been executed, including static initializers, constructors, and finalizers. Automatic deserialization of fields means that an attacker may craft a nested combination of objects on which the executed initialization code may have unforeseen effects, such as the execution of arbitrary code.

    There are many different serialization frameworks. This query currently supports Pickle, Marshal and Yaml.


    ## Recommendation
    Avoid deserialization of untrusted data if at all possible. If the architecture permits it then use other formats instead of serialized objects, for example JSON.

    If you need to use YAML, use the `yaml.safe_load` function.


    ## Example
    The following example calls `pickle.loads` directly on a value provided by an incoming HTTP request. Pickle then creates a new value from untrusted data, and is therefore inherently unsafe.


    ```python

    from django.conf.urls import url
    import pickle

    def unsafe(pickled):
        return pickle.loads(pickled)

    urlpatterns = [
        url(r'^(?P<object>.*)$', unsafe)
    ]
    ```
    Changing the code to use `json.loads` instead of `pickle.loads` removes the vulnerability.


    ```python

    from django.conf.urls import url
    import json

    def safe(pickled):
        return json.loads(pickled)

    urlpatterns = [
        url(r'^(?P<object>.*)$', safe)
    ]

    ```

    # URL redirection from remote source
    Directly incorporating user input into a URL redirect request without validating the input can facilitate phishing attacks. In these attacks, unsuspecting users can be redirected to a malicious site that looks very similar to the real site they intend to visit, but which is controlled by the attacker.


    ## Recommendation
    To guard against untrusted URL redirection, it is advisable to avoid putting user input directly into a redirect URL. Instead, maintain a list of authorized redirects on the server; then choose from that list based on the user input provided.

    If this is not possible, then the user input should be validated in some other way, for example, by verifying that the target URL does not include an explicit host name.


    ## Example
    The following example shows an HTTP request parameter being used directly in a URL redirect without validating the input, which facilitates phishing attacks:


    ```python
    from flask import Flask, request, redirect

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        return redirect(target, code=302)

    ```
    If you know the set of valid redirect targets, you can maintain a list of them on the server and check that the user input is in that list:


    ```python
    from flask import Flask, request, redirect

    VALID_REDIRECT = "http://cwe.mitre.org/data/definitions/601.html"

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        if target == VALID_REDIRECT:
            return redirect(target, code=302)
        else:
            # ignore the target and redirect to the home page
            return redirect('/', code=302)

    ```
    Often this is not possible, so an alternative is to check that the target URL does not specify an explicit host name. For example, you can use the `urlparse` function from the Python standard library to parse the URL and check that the `netloc` attribute is empty.

    Note, however, that some cases are not handled as we desire out-of-the-box by `urlparse`, so we need to adjust two things, as shown in the example below:

    * Many browsers accept backslash characters (`\`) as equivalent to forward slash characters (`/`) in URLs, but the `urlparse` function does not.
    * Mistyped URLs such as `https:/example.com` or `https:///example.com` are parsed as having an empty `netloc` attribute, while browsers will still redirect to the correct site.

    ```python
    from flask import Flask, request, redirect
    from urllib.parse import urlparse

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        target = target.replace('\\', '')
        if not urlparse(target).netloc and not urlparse(target).scheme:
            # relative path, safe to redirect
            return redirect(target, code=302)
        # ignore the target and redirect to the home page
        return redirect('/', code=302)

    ```
    For Django application, you can use the function `url_has_allowed_host_and_scheme` to check that a URL is safe to redirect to, as shown in the following example:


    ```python
    from django.http import HttpResponseRedirect
    from django.shortcuts import redirect
    from django.utils.http import url_has_allowed_host_and_scheme
    from django.views import View

    class RedirectView(View):
        def get(self, request, *args, **kwargs):
            target = request.GET.get('target', '')
            if url_has_allowed_host_and_scheme(target, allowed_hosts=None):
                return HttpResponseRedirect(target)
            else:
                # ignore the target and redirect to the home page
                return redirect('/')
    ```
    Note that `url_has_allowed_host_and_scheme` handles backslashes correctly, so no additional processing is required.

    # XML external entity expansion
    Parsing untrusted XML files with a weakly configured XML parser may lead to an XML External Entity (XXE) attack. This type of attack uses external entity references to access arbitrary files on a system, carry out denial-of-service (DoS) attacks, or server-side request forgery. Even when the result of parsing is not returned to the user, DoS attacks are still possible and out-of-band data retrieval techniques may allow attackers to steal sensitive data.


    ## Recommendation
    The easiest way to prevent XXE attacks is to disable external entity handling when parsing untrusted data. How this is done depends on the library being used. Note that some libraries, such as recent versions of the XML libraries in the standard library of Python 3, disable entity expansion by default, so unless you have explicitly enabled entity expansion, no further action needs to be taken.

    We recommend using the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package, which has been created to prevent XML attacks (both XXE and XML bombs).


    ## Example
    The following example uses the `lxml` XML parser to parse a string `xml_src`. That string is from an untrusted source, so this code is vulnerable to an XXE attack, since the [ default parser](https://lxml.de/apidoc/lxml.etree.html#lxml.etree.XMLParser) from `lxml.etree` allows local external entities to be resolved.


    ```python
    from flask import Flask, request
    import lxml.etree

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = lxml.etree.fromstring(xml_src)
        return lxml.etree.tostring(doc)

    ```
    To guard against XXE attacks with the `lxml` library, you should create a parser with `resolve_entities` set to `false`. This means that no entity expansion is undertaken, although standard predefined entities such as `&gt;`, for writing `>` inside the text of an XML element, are still allowed.


    ```python
    from flask import Flask, request
    import lxml.etree

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        parser = lxml.etree.XMLParser(resolve_entities=False)
        doc = lxml.etree.fromstring(xml_src, parser=parser)
        return lxml.etree.tostring(doc)

    ```

    # XPath query built from user-controlled sources
    If an XPath expression is built using string concatenation, and the components of the concatenation include user input, it makes it very easy for a user to create a malicious XPath expression.


    ## Recommendation
    If user input must be included in an XPath expression, either sanitize the data or use variable references to safely embed it without altering the structure of the expression.


    ## Example
    In the example below, the xpath query is controlled by the user and hence leads to a vulnerability.


    ```python
    from lxml import etree
    from io import StringIO

    from django.urls import path
    from django.http import HttpResponse
    from django.template import Template, Context, Engine, engines


    def a(request):
        value = request.GET['xpath']
        f = StringIO('<foo><bar></bar></foo>')
        tree = etree.parse(f)
        r = tree.xpath("/tag[@id='%s']" % value)


    urlpatterns = [
        path('a', a)
    ]

    ```
    This can be fixed by using a parameterized query as shown below.


    ```python
    from lxml import etree
    from io import StringIO

    from django.urls import path
    from django.http import HttpResponse
    from django.template import Template, Context, Engine, engines


    def a(request):
        value = request.GET['xpath']
        f = StringIO('<foo><bar></bar></foo>')
        tree = etree.parse(f)
        r = tree.xpath("/tag[@id=$tagid]", tagid=value)


    urlpatterns = [
        path('a', a)
    ]

    ```

    \ by crafting an expensive input string for the regular expression to match.\n\
    \nThe regular expression engine provided by Python uses a backtracking non-deterministic\
    \ finite automata to implement regular expression matching. While this approach\
    \ is space-efficient and allows supporting advanced features like capture groups,\
    \ it is not time-efficient in general. The worst-case time complexity of such\

    \ of a certain shape, increasing the input length by ten characters may make the\
    \ automaton about 1000 times slower.\n\nTypically, a regular expression is affected\
    \ by this problem if it contains a repetition of the form `r*` or `r+` where the\
    \ sub-expression `r` is ambiguous in the sense that it can match some string in\
    \ multiple ways. More information about the precise circumstances can be found\
    \ in the references.\n\n\n## Recommendation\nModify the regular expression to\
    \ remove the ambiguity, or ensure that the strings matched with the regular expression\
    \ are short enough that the time-complexity does not matter.\n\n\n## Example\n\
    Consider this use of a regular expression, which removes all leading and trailing\
    \ whitespace in a string:\n\n```python\n\nre.sub(r\"^\\s+|\\s+$\", \"\", text)\
    \ # BAD\n```\nThe sub-expression `\"\\s+$\"` will match the whitespace characters\
    \ in `text` from left to right, but it can start matching anywhere within a whitespace\
    \ sequence. This is problematic for strings that do **not** end with a whitespace\
    \ character. Such a string will force the regular expression engine to process\
    \ each whitespace sequence once per whitespace character in the sequence.\n\n\
    This ultimately means that the time cost of trimming a string is quadratic in\
    \ the length of the string. So a string like `\"a b\"` will take milliseconds\
    \ to process, but a similar string with a million spaces instead of just one will\
    \ take several minutes.\n\nAvoid this problem by rewriting the regular expression\
    \ to not contain the ambiguity about when to start matching whitespace sequences.\
    \ For instance, by using a negative look-behind (`^\\s+|(?<!\\s)\\s+$`), or just\
    \ by using the built-in strip method (`text.strip()`).\n\nNote that the sub-expression\
    \ `\"^\\s+\"` is **not** problematic as the `^` anchor restricts when that sub-expression\
    \ can start matching, and as the regular expression engine matches from left to\
    \ right.\n\n\n## Example\nAs a similar, but slightly subtler problem, consider\
    \ the regular expression that matches lines with numbers, possibly written using\
    \ scientific notation:\n\n```python\n\n^0\\.\\d+E?\\d+$ # BAD\n```\nThe problem\
    \ with this regular expression is in the sub-expression `\\d+E?\\d+` because the\
    \ second `\\d+` can start matching digits anywhere after the first match of the\
    \ first `\\d+` if there is no `E` in the input string.\n\nThis is problematic\
    \ for strings that do **not** end with a digit. Such a string will force the regular\
    \ expression engine to process each digit sequence once per digit in the sequence,\
    \ again leading to a quadratic time complexity.\n\nTo make the processing faster,\
    \ the regular expression should be rewritten such that the two `\\d+` sub-expressions\
    \ do not have overlapping matches: `^0\\.\\d+(E\\d+)?$`.\n\n\n## Example\nSometimes\
    \ it is unclear how a regular expression can be rewritten to avoid the problem.\
    \ In such cases, it often suffices to limit the length of the input string. For\
    \ instance, the following regular expression is used to match numbers, and on\
    \ some non-number inputs it can have quadratic time complexity:\n\n```python\n\
    \nmatch = re.search(r'^(\\+|-)?(\\d+|(\\d*\\.\\d*))?(E|e)?([-+])?(\\d+)?$', str)\
    \ \n```\nIt is not immediately obvious how to rewrite this regular expression\
    \ to avoid the problem. However, you can mitigate performance issues by limiting\
    \ the length to 1000 characters, which will always finish in a reasonable amount\
    \ of time.\n\n```python\n\nif len(str) > 1000:\n    raise ValueError(\"Input too\
    \ long\")\n\nmatch = re.search(r'^(\\+|-)?(\\d+|(\\d*\\.\\d*))?(E|e)?([-+])?(\\\
    d+)?$', str) \n```\n\n## References\n* OWASP: [Regular expression Denial of Service\

    ## Example
    Consider this regular expression:

    ```python

    ^_(__|.)+_$
    ```
    Its sub-expression `"(__|.)+?"` can match the string `"__"` either by the first alternative `"__"` to the left of the `"|"` operator, or by two repetitions of the second alternative `"."` to the right. Thus, a string consisting of an odd number of underscores followed by some other character will cause the regular expression engine to run for an exponential amount of time before rejecting the input.

    This problem can be avoided by rewriting the regular expression to remove the ambiguity between the two branches of the alternative inside the repetition:

    ```python

    ^_(__|[^_])+_$
    ```

    # Regular expression injection
    Constructing a regular expression with unsanitized user input is dangerous as a malicious user may be able to modify the meaning of the expression. In particular, such a user may be able to provide a regular expression fragment that takes exponential time in the worst case, and use that to perform a Denial of Service attack.


    ## Recommendation
    Before embedding user input into a regular expression, use a sanitization function such as `re.escape` to escape meta-characters that have a special meaning regarding regular expressions' syntax.


    ## Example
    The following examples are based on a simple Flask web server environment.

    The following example shows a HTTP request parameter that is used to construct a regular expression without sanitizing it first:


    ```python
    from flask import request, Flask
    import re


    @app.route("/direct")
    def direct():
        unsafe_pattern = request.args["pattern"]
        re.search(unsafe_pattern, "")


    @app.route("/compile")
    def compile():
        unsafe_pattern = request.args["pattern"]
        compiled_pattern = re.compile(unsafe_pattern)
        compiled_pattern.search("")

    ```
    Instead, the request parameter should be sanitized first, for example using the function `re.escape`. This ensures that the user cannot insert characters which have a special meaning in regular expressions.


    ```python
    from flask import request, Flask
    import re


    @app.route("/direct")
    def direct():
        unsafe_pattern = request.args['pattern']
        safe_pattern = re.escape(unsafe_pattern)
        re.search(safe_pattern, "")


    @app.route("/compile")
    def compile():
        unsafe_pattern = request.args['pattern']
        safe_pattern = re.escape(unsafe_pattern)
        compiled_pattern = re.compile(safe_pattern)
        compiled_pattern.search("")

    ```

    # Overly permissive file permissions
    When creating a file, POSIX systems allow permissions to be specified for owner, group and others separately. Permissions should be kept as strict as possible, preventing access to the files contents by other users.


    ## Recommendation
    Restrict the file permissions of files to prevent any but the owner being able to read or write to that file

    # XML internal entity expansion
    Parsing untrusted XML files with a weakly configured XML parser may be vulnerable to denial-of-service (DoS) attacks exploiting uncontrolled internal entity expansion.

    In XML, so-called *internal entities* are a mechanism for introducing an abbreviation for a piece of text or part of a document. When a parser that has been configured to expand entities encounters a reference to an internal entity, it replaces the entity by the data it represents. The replacement text may itself contain other entity references, which are expanded recursively. This means that entity expansion can increase document size dramatically.

    If untrusted XML is parsed with entity expansion enabled, a malicious attacker could submit a document that contains very deeply nested entity definitions, causing the parser to take a very long time or use large amounts of memory. This is sometimes called an *XML bomb* attack.


    ## Recommendation
    The safest way to prevent XML bomb attacks is to disable entity expansion when parsing untrusted data. Whether this can be done depends on the library being used. Note that some libraries, such as `lxml`, have measures enabled by default to prevent such DoS XML attacks, so unless you have explicitly set `huge_tree` to `True`, no further action is needed.

    We recommend using the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package, which has been created to prevent XML attacks (both XXE and XML bombs).


    ## Example
    The following example uses the `xml.etree` XML parser provided by the Python standard library to parse a string `xml_src`. That string is from an untrusted source, so this code is vulnerable to a DoS attack, since the `xml.etree` XML parser expands internal entities by default:


    ```python
    from flask import Flask, request
    import xml.etree.ElementTree as ET

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = ET.fromstring(xml_src)
        return ET.tostring(doc)

    ```
    It is not possible to guard against internal entity expansion with `xml.etree`, so to guard against these attacks, the following example uses the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package instead, which is not exposed to such internal entity expansion attacks.


    ```python
    from flask import Flask, request
    import defusedxml.ElementTree as ET

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = ET.fromstring(xml_src)
        return ET.tostring(doc)

    ```

    # Full server-side request forgery
    Directly incorporating user input into an HTTP request without validating the input can facilitate server-side request forgery (SSRF) attacks. In these attacks, the request may be changed, directed at a different server, or via a different protocol. This can allow the attacker to obtain sensitive information or perform actions with escalated privilege.

    We make a distinctions between how much of the URL an attacker can control:

    * **Full SSRF**: where the full URL can be controlled.
    * **Partial SSRF**: where only part of the URL can be controlled, such as the path component of a URL to a hardcoded domain.


    Partial control of a URL is often much harder to exploit. Therefore we have created a separate query for each of these.

    This query covers full SSRF, to find partial SSRF use the `py/partial-ssrf` query.


    ## Recommendation
    To guard against SSRF attacks you should avoid putting user-provided input directly into a request URL. On the application level, maintain a list of authorized URLs on the server and choose from that list based on the input provided. If that is not possible, one should verify the IP address for all user-controlled requests to ensure they are not private. This requires saving the verified IP address of each domain, then utilizing a custom HTTP adapter to ensure that future requests to that domain use the verified IP address. On the network level, you can segment the vulnerable application into its own LAN or block access to specific devices.


    ## Example
    The following example shows code vulnerable to a full SSRF attack, because it uses untrusted input (HTTP request parameter) directly to construct a URL. By using `evil.com#` as the `target` value, the requested URL will be `https://evil.com#.example.com/data/`. It also shows how to remedy the problem by using the user input select a known fixed string.


    ```python
    import requests
    from flask import Flask, request

    app = Flask(__name__)

    @app.route("/full_ssrf")
    def full_ssrf():
        target = request.args["target"]

        # BAD: user has full control of URL
        resp = requests.get("https://" + target + ".example.com/data/")

        # GOOD: `subdomain` is controlled by the server.
        subdomain = "europe" if target == "EU" else "world"
        resp = requests.get("https://" + subdomain + ".example.com/data/")

    ```

    ## Example
    The following example shows code vulnerable to a partial SSRF attack, because it uses untrusted input (HTTP request parameter) directly to construct a URL. By using `../transfer-funds-to/123?amount=456` as the `user_id` value, the requested URL will be `https://api.example.com/transfer-funds-to/123?amount=456`. It also shows how to remedy the problem by validating the input.


    ```python
    import requests
    from flask import Flask, request

    app = Flask(__name__)

    @app.route("/partial_ssrf")
    def partial_ssrf():
        user_id = request.args["user_id"]

        # BAD: user can fully control the path component of the URL
        resp = requests.get("https://api.example.com/user_info/" + user_id)

        if user_id.isalnum():
            # GOOD: user_id is restricted to be alpha-numeric, and cannot alter path component of URL
            resp = requests.get("https://api.example.com/user_info/" + user_id)

    ```

    # NoSQL Injection
    Passing user-controlled sources into NoSQL queries can result in a NoSQL injection flaw. This tainted NoSQL query containing a user-controlled source can then execute a malicious query in a NoSQL database such as MongoDB. In order for the user-controlled source to taint the NoSQL query, the user-controller source must be converted into a Python object using something like `json.loads` or `xmltodict.parse`.

    Because a user-controlled source is passed into the query, the malicious user can have complete control over the query itself. When the tainted query is executed, the malicious user can commit malicious actions such as bypassing role restrictions or accessing and modifying restricted data in the NoSQL database.


    ## Recommendation
    NoSQL injections can be prevented by escaping user-input's special characters that are passed into the NoSQL query from the user-supplied source. Alternatively, using a sanitize library such as MongoSanitizer will ensure that user-supplied sources can not act as a malicious query.


    ## Example
    In the example below, the user-supplied source is passed to a MongoDB function that queries the MongoDB database.


    ```python
    from flask import Flask, request
    from flask_pymongo import PyMongo
    import json

    mongo = PyMongo(app)


    @app.route("/")
    def home_page():
        unsanitized_search = request.args['search']
        json_search = json.loads(unsanitized_search)

        result = mongo.db.user.find({'name': json_search})

    ```
    This can be fixed by using a sanitizer library like MongoSanitizer as shown in this annotated code version below.


    ```python
    from flask import Flask, request
    from flask_pymongo import PyMongo
    from mongosanitizer.sanitizer import sanitize
    import json

    mongo = PyMongo(app)


    @app.route("/")
    def home_page():
        unsafe_search = request.args['search']
        json_search = json.loads(unsafe_search)
        safe_search = sanitize(unsanitized_search)

        result = client.db.collection.find_one({'data': safe_search})

    ```

    # 'input' function used in Python 2
    In Python 2, a call to the `input()` function, `input(prompt)` is equivalent to `eval(raw_input(prompt))`. Evaluating user input without any checking can be a serious security flaw.


    ## Recommendation
    Get user input with `raw_input(prompt)` and then validate that input before evaluating. If the expected input is a number or string, then `ast.literal_eval()` can always be used safely.

    # Binding a socket to all network interfaces
    Sockets can be used to communicate with other machines on a network. You can use the (IP address, port) pair to define the access restrictions for the socket you create. When using the built-in Python `socket` module (for instance, when building a message sender service or an FTP server data transmitter), one has to bind the port to some interface. When you bind the port to all interfaces using `0.0.0.0` as the IP address, you essentially allow it to accept connections from any IPv4 address provided that it can get to the socket via routing. Binding to all interfaces is therefore associated with security risks.


    ## Recommendation
    Bind your service incoming traffic only to a dedicated interface. If you need to bind more than one interface using the built-in `socket` module, create multiple sockets (instead of binding to one socket to all interfaces).


    ## Example
    In this example, two sockets are insecure because they are bound to all interfaces; one through the `0.0.0.0` notation and another one through an empty string `''`.


    ```python
    import socket

    # binds to all interfaces, insecure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('0.0.0.0', 31137))

    # binds to all interfaces, insecure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('', 4040))

    # binds only to a dedicated interface, secure
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.bind(('84.68.10.12', 8080))

    ```

    # Construction of a cookie using user-supplied input
    Constructing cookies from user input can allow an attacker to control a user's cookie. This may lead to a session fixation attack. Additionally, client code may not expect a cookie to contain attacker-controlled data, and fail to sanitize it for common vulnerabilities such as Cross Site Scripting (XSS). An attacker manipulating the raw cookie header may additionally be able to set cookie attributes such as `HttpOnly` to insecure values.


    ## Recommendation
    Do not use raw user input to construct cookies.


    ## Example
    In the following cases, a cookie is constructed for a Flask response using user input. The first uses `set_cookie`, and the second sets a cookie's raw value through the `set-cookie` header.


    ```python
    from flask import request, make_response


    @app.route("/1")
    def set_cookie():
        resp = make_response()
        resp.set_cookie(request.args["name"], # BAD: User input is used to set the cookie's name and value
                        value=request.args["name"])
        return resp


    @app.route("/2")
    def set_cookie_header():
        resp = make_response()
        resp.headers['Set-Cookie'] = f"{request.args['name']}={request.args['name']};" # BAD: User input is used to set the raw cookie header.
        return resp

    ```

    # Incomplete regular expression for hostnames
    Sanitizing untrusted URLs is a common technique for preventing attacks such as request forgeries and malicious redirections. Often, this is done by checking that the host of a URL is in a set of allowed hosts.

    If a regular expression implements such a check, it is easy to accidentally make the check too permissive by not escaping the `.` meta-characters appropriately. Even if the check is not used in a security-critical context, the incomplete check may still cause undesirable behaviors when it accidentally succeeds.


    ## Recommendation
    Escape all meta-characters appropriately when constructing regular expressions for security checks, and pay special attention to the `.` meta-character.


    ## Example
    The following example code checks that a URL redirection will reach the `example.com` domain, or one of its subdomains.


    ```python
    from flask import Flask, request, redirect
    import re

    app = Flask(__name__)

    UNSAFE_REGEX = re.compile("(www|beta).example.com/")
    SAFE_REGEX = re.compile(r"(www|beta)\.example\.com/")

    @app.route('/some/path/bad')
    def unsafe(request):
        target = request.args.get('target', '')
        if UNSAFE_REGEX.match(target):
            return redirect(target)

    @app.route('/some/path/good')
    def safe(request):
        target = request.args.get('target', '')
        if SAFE_REGEX.match(target):
            return redirect(target)

    ```
    The `unsafe` check is easy to bypass because the unescaped `.` allows for any character before `example.com`, effectively allowing the redirect to go to an attacker-controlled domain such as `wwwXexample.com`.

    The `safe` check closes this vulnerability by escaping the `.` so that URLs of the form `wwwXexample.com` are rejected.

    # Incomplete URL substring sanitization
    Sanitizing untrusted URLs is a common technique for preventing attacks such as request forgeries and malicious redirections. Usually, this is done by checking that the host of a URL is in a set of allowed hosts.

    However, treating the URL as a string and checking if one of the allowed hosts is a substring of the URL is very prone to errors. Malicious URLs can bypass such security checks by embedding one of the allowed hosts in an unexpected location.

    Even if the substring check is not used in a security-critical context, the incomplete check may still cause undesirable behaviors when the check succeeds accidentally.


    ## Recommendation
    Parse a URL before performing a check on its host value, and ensure that the check handles arbitrary subdomain sequences correctly.


    ## Example
    The following example code checks that a URL redirection will reach the `example.com` domain.


    ```python
    from flask import Flask, request, redirect
    from urllib.parse import urlparse

    app = Flask(__name__)

    # Not safe, as "evil-example.net/example.com" would be accepted

    @app.route('/some/path/bad1')
    def unsafe1(request):
        target = request.args.get('target', '')
        if "example.com" in target:
            return redirect(target)

    # Not safe, as "benign-looking-prefix-example.com" would be accepted

    @app.route('/some/path/bad2')
    def unsafe2(request):
        target = request.args.get('target', '')
        if target.endswith("example.com"):
            return redirect(target)



    #Simplest and safest approach is to use an allowlist

    @app.route('/some/path/good1')
    def safe1(request):
        allowlist = [
            "example.com/home",
            "example.com/login",
        ]
        target = request.args.get('target', '')
        if target in allowlist:
            return redirect(target)

    #More complex example allowing sub-domains.

    @app.route('/some/path/good2')
    def safe2(request):
        target = request.args.get('target', '')
        host = urlparse(target).hostname
        #Note the '.' preceding example.com
        if host and host.endswith(".example.com"):
            return redirect(target)


    ```
    The first two examples show unsafe checks that are easily bypassed. In `unsafe1` the attacker can simply add `example.com` anywhere in the url. For example, `http://evil-example.net/example.com`.

    In `unsafe2` the attacker must use a hostname ending in `example.com`, but that is easy to do. For example, `http://benign-looking-prefix-example.com`.

    The second two examples show safe checks. In `safe1`, an allowlist is used. Although fairly inflexible, this is easy to get right and is most likely to be safe.

    In `safe2`, `urlparse` is used to parse the URL, then the hostname is checked to make sure it ends with `.example.com`.

    # Overly permissive regular expression range
    It's easy to write a regular expression range that matches a wider range of characters than you intended. For example, `/[a-zA-z]/` matches all lowercase and all uppercase letters, as you would expect, but it also matches the characters: `` [ \ ] ^ _ ` ``.

    Another common problem is failing to escape the dash character in a regular expression. An unescaped dash is interpreted as part of a range. For example, in the character class `[a-zA-Z0-9%=.,-_]` the last character range matches the 55 characters between `,` and `_` (both included), which overlaps with the range `[0-9]` and is clearly not intended by the writer.


    ## Recommendation
    Avoid any confusion about which characters are included in the range by writing unambiguous regular expressions. Always check that character ranges match only the expected characters.


    ## Example
    The following example code is intended to check whether a string is a valid 6 digit hex color.

    ```python

    import re
    def is_valid_hex_color(color):
        return re.match(r'^#[0-9a-fA-f]{6}$', color) is not None

    ```
    However, the `A-f` range is overly large and matches every uppercase character. It would parse a "color" like `#XXYYZZ` as valid.

    The fix is to use an uppercase `A-F` range instead.

    ```python

    import re
    def is_valid_hex_color(color):
        return re.match(r'^#[0-9a-fA-F]{6}$', color) is not None

    ```

    # Uncontrolled data used in path expression
    Accessing files using paths constructed from user-controlled data can allow an attacker to access unexpected resources. This can result in sensitive information being revealed or deleted, or an attacker being able to influence behavior by modifying unexpected files.


    ## Recommendation
    Validate paths constructed from untrusted user input before using them to access files.

    The choice of validation depends on the use case.

    If you want to allow paths spanning multiple folders, a common strategy is to make sure that the constructed file path is contained within a safe root folder. First, normalize the path using `os.path.normpath` or `os.path.realpath` (make sure to use the latter if symlinks are a consideration) to remove any internal ".." segments and/or follow links. Then check that the normalized path starts with the root folder. Note that the normalization step is important, since otherwise even a path that starts with the root folder could be used to access files outside the root folder.

    More restrictive options include using a library function like `werkzeug.utils.secure_filename` to eliminate any special characters from the file path, or restricting the path to a known list of safe paths. These options are safe, but can only be used in particular circumstances.


    ## Example
    In the first example, a file name is read from an HTTP request and then used to access a file. However, a malicious user could enter a file name that is an absolute path, such as `"/etc/passwd"`.

    In the second example, it appears that the user is restricted to opening a file within the `"user"` home directory. However, a malicious user could enter a file name containing special characters. For example, the string `"../../../etc/passwd"` will result in the code reading the file located at `"/server/static/images/../../../etc/passwd"`, which is the system's password file. This file would then be sent back to the user, giving them access to all the system's passwords. Note that a user could also use an absolute path here, since the result of `os.path.join("/server/static/images/", "/etc/passwd")` is `"/etc/passwd"`.

    In the third example, the path used to access the file system is normalized *before* being checked against a known prefix. This ensures that regardless of the user input, the resulting path is safe.


    ```python
    import os.path
    from flask import Flask, request, abort

    app = Flask(__name__)

    @app.route("/user_picture1")
    def user_picture1():
        filename = request.args.get('p')
        # BAD: This could read any file on the file system
        data = open(filename, 'rb').read()
        return data

    @app.route("/user_picture2")
    def user_picture2():
        base_path = '/server/static/images'
        filename = request.args.get('p')
        # BAD: This could still read any file on the file system
        data = open(os.path.join(base_path, filename), 'rb').read()
        return data

    @app.route("/user_picture3")
    def user_picture3():
        base_path = '/server/static/images'
        filename = request.args.get('p')
        #GOOD -- Verify with normalised version of path
        fullpath = os.path.normpath(os.path.join(base_path, filename))
        if not fullpath.startswith(base_path):
            raise Exception("not allowed")
        data = open(fullpath, 'rb').read()
        return data

    ```

    # Arbitrary file write during tarfile extraction
    Extracting files from a malicious tar archive without validating that the destination file path is within the destination directory can cause files outside the destination directory to be overwritten, due to the possible presence of directory traversal elements (`..`) in archive paths.

    Tar archives contain archive entries representing each file in the archive. These entries include a file path for the entry, but these file paths are not restricted and may contain unexpected special elements such as the directory traversal element (`..`). If these file paths are used to determine an output file to write the contents of the archive item to, then the file may be written to an unexpected location. This can result in sensitive information being revealed or deleted, or an attacker being able to influence behavior by modifying unexpected files.

    For example, if a tar archive contains a file entry `..\sneaky-file`, and the tar archive is extracted to the directory `c:\output`, then naively combining the paths would result in an output file path of `c:\output\..\sneaky-file`, which would cause the file to be written to `c:\sneaky-file`.


    ## Recommendation
    Ensure that output paths constructed from tar archive entries are validated to prevent writing files to unexpected locations.

    The recommended way of writing an output file from a tar archive entry is to check that `".."` does not occur in the path.


    ## Example
    In this example an archive is extracted without validating file paths. If `archive.tar` contained relative paths (for instance, if it were created by something like `tar -cf archive.tar ../file.txt`) then executing this code could write to locations outside the destination directory.


    ```python
    import sys
    import tarfile

    with tarfile.open(sys.argv[1]) as tar:
        #BAD : This could write any file on the filesystem.
        for entry in tar:
            tar.extract(entry, "/tmp/unpack/")

    ```
    To fix this vulnerability, we need to check that the path does not contain any `".."` elements in it.


    ```python
    import sys
    import tarfile
    import os.path

    with tarfile.open(sys.argv[1]) as tar:
        for entry in tar:
            #GOOD: Check that entry is safe
            if os.path.isabs(entry.name) or ".." in entry.name:
                raise ValueError("Illegal tar archive entry")
            tar.extract(entry, "/tmp/unpack/")

    ```

    \ in s.__name__ %}{{s()._module.__builtins__['__import__']('os').system('cat /etc/passwd')\
    \ }}{% endif %}{% endfor %}\n\n```\nIn the following case, user input is not used\
    \ to construct the template. Instead, it is only used as the parameters to render\
    \ the template, which is safe.\n\n\n```python\nfrom django.urls import path\n\
    from django.http import HttpResponse\nfrom jinja2 import Template, escape\n\n\n\
    def a(request):\n    # GOOD: Template is a constant, not constructed from user\

    \ = [\n    path('a', a),\n]\n```\nIn the following case, a `SandboxedEnvironment`\
    \ is used, preventing remote code execution.\n\n\n```python\nfrom django.urls\
    \ import path\nfrom django.http import HttpResponse\nfrom jinja2 import escape\n\
    from jinja2.sandbox import SandboxedEnvironment\n\n\ndef a(request):\n    env\

    # Uncontrolled command line
    Code that passes user input directly to `exec`, `eval`, or some other library routine that executes a command, allows the user to execute malicious code.


    ## Recommendation
    If possible, use hard-coded string literals to specify the command to run or the library to load. Instead of passing the user input directly to the process or library function, examine the user input and then choose among hard-coded string literals.

    If the applicable libraries or commands cannot be determined at compile time, then add code to verify that the user input string is safe before using it.


    ## Example
    The following example shows two functions. The first is unsafe as it takes a shell script that can be changed by a user, and passes it straight to `subprocess.call()` without examining it first. The second is safe as it selects the command from a predefined allowlist.


    ```python

    urlpatterns = [
        # Route to command_execution
        url(r'^command-ex1$', command_execution_unsafe, name='command-execution-unsafe'),
        url(r'^command-ex2$', command_execution_safe, name='command-execution-safe')
    ]

    COMMANDS = {
        "list" :"ls",
        "stat" : "stat"
    }

    def command_execution_unsafe(request):
        if request.method == 'POST':
            action = request.POST.get('action', '')
            #BAD -- No sanitizing of input
            subprocess.call(["application", action])

    def command_execution_safe(request):
        if request.method == 'POST':
            action = request.POST.get('action', '')
            #GOOD -- Use an allowlist
            subprocess.call(["application", COMMANDS[action]])

    # Jinja2 templating with autoescape=False
    Cross-site scripting (XSS) attacks can occur if untrusted input is not escaped. This applies to templates as well as code. The `jinja2` templates may be vulnerable to XSS if the environment has `autoescape` set to `False`. Unfortunately, `jinja2` sets `autoescape` to `False` by default. Explicitly setting `autoescape` to `True` when creating an `Environment` object will prevent this.


    ## Recommendation
    Avoid setting jinja2 autoescape to False. Jinja2 provides the function `select_autoescape` to make sure that the correct auto-escaping is chosen. For example, it can be used when creating an environment `Environment(autoescape=select_autoescape(['html', 'xml'])`


    ## Example
    The following example is a minimal Flask app which shows a safe and an unsafe way to render the given name back to the page. The first view is unsafe as `first_name` is not escaped, leaving the page vulnerable to cross-site scripting attacks. The second view is safe as `first_name` is escaped, so it is not vulnerable to cross-site scripting attacks.


    ```python
    from flask import Flask, request, make_response, escape
    from jinja2 import Environment, select_autoescape, FileSystemLoader

    app = Flask(__name__)
    loader = FileSystemLoader( searchpath="templates/" )

    unsafe_env = Environment(loader=loader)
    safe1_env = Environment(loader=loader, autoescape=True)
    safe2_env = Environment(loader=loader, autoescape=select_autoescape())

    def render_response_from_env(env):
        name = request.args.get('name', '')
        template = env.get_template('template.html')
        return make_response(template.render(name=name))

    @app.route('/unsafe')
    def unsafe():
        return render_response_from_env(unsafe_env)

    @app.route('/safe1')

        return render_response_from_env(safe1_env)

    @app.route('/safe2')

    # Reflected server-side cross-site scripting
    Directly writing user input (for example, an HTTP request parameter) to a webpage without properly sanitizing the input first, allows for a cross-site scripting vulnerability.


    ## Recommendation
    To guard against cross-site scripting, consider escaping the input before writing user input to the page. The standard library provides escaping functions: `html.escape()` for Python 3.2 upwards or `cgi.escape()` older versions of Python. Most frameworks also provide their own escaping functions, for example `flask.escape()`.


    ## Example
    The following example is a minimal flask app which shows a safe and unsafe way to render the given name back to the page. The first view is unsafe as `first_name` is not escaped, leaving the page vulnerable to cross-site scripting attacks. The second view is safe as `first_name` is escaped, so it is not vulnerable to cross-site scripting attacks.


    ```python
    from flask import Flask, request, make_response, escape

    app = Flask(__name__)

    @app.route('/unsafe')
    def unsafe():
        first_name = request.args.get('name', '')
        return make_response("Your name is " + first_name)

    @app.route('/safe')
    def safe():
        first_name = request.args.get('name', '')
        return make_response("Your name is " + escape(first_name))

    ```

    # SQL query built from user-controlled sources
    If a database query (such as a SQL or NoSQL query) is built from user-provided data without sufficient sanitization, a user may be able to run malicious database queries.

    This also includes using the `TextClause` class in the `[SQLAlchemy](https://pypi.org/project/SQLAlchemy/)` PyPI package, which is used to represent a literal SQL fragment and is inserted directly into the final SQL when used in a query built using the ORM.


    ## Recommendation
    Most database connector libraries offer a way of safely embedding untrusted data into a query by means of query parameters or prepared statements.


    ## Example
    In the following snippet, a user is fetched from the database using three different queries.

    In the first case, the query string is built by directly using string formatting from a user-supplied request parameter. The parameter may include quote characters, so this code is vulnerable to a SQL injection attack.

    In the second case, the user-supplied request attribute is passed to the database using query parameters. The database connector library will take care of escaping and inserting quotes as needed.

    In the third case, the placeholder in the SQL string has been manually quoted. Since most databaseconnector libraries will insert their own quotes, doing so yourself will make the code vulnerable to SQL injection attacks. In this example, if `username` was `; DROP ALL TABLES -- `, the final SQL query would be `SELECT * FROM users WHERE username = ''; DROP ALL TABLES -- ''`


    ```python
    from django.conf.urls import url
    from django.db import connection


    def show_user(request, username):
        with connection.cursor() as cursor:
            # BAD -- Using string formatting
            cursor.execute("SELECT * FROM users WHERE username = '%s'" % username)
            user = cursor.fetchone()

            # GOOD -- Using parameters
            cursor.execute("SELECT * FROM users WHERE username = %s", username)
            user = cursor.fetchone()

            # BAD -- Manually quoting placeholder (%s)
            cursor.execute("SELECT * FROM users WHERE username = '%s'", username)
            user = cursor.fetchone()

    urlpatterns = [url(r'^users/(?P<username>[^/]+)$', show_user)]

    # LDAP query built from user-controlled sources
    If an LDAP query or DN is built using string concatenation or string formatting, and the components of the concatenation include user input without any proper sanitization, a user is likely to be able to run malicious LDAP queries.


    ## Recommendation
    If user input must be included in an LDAP query or DN, it should be escaped to avoid a malicious user providing special characters that change the meaning of the query. In Python2, user input should be escaped with `ldap.dn.escape_dn_chars` or `ldap.filter.escape_filter_chars`, while in Python3, user input should be escaped with `ldap3.utils.dn.escape_rdn` or `ldap3.utils.conv.escape_filter_chars` depending on the component tainted by the user. A good practice is to escape filter characters that could change the meaning of the query (https://tools.ietf.org/search/rfc4515\#section-3).


    ## Example
    In the following examples, the code accepts both `username` and `dc` from the user, which it then uses to build a LDAP query and DN.

    The first and the second example uses the unsanitized user input directly in the search filter and DN for the LDAP query. A malicious user could provide special characters to change the meaning of these components, and search for a completely different set of values.


    ```python
    from flask import request, Flask
    import ldap


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        dn = "dc={}".format(unsafe_dc)
        search_filter = "(user={})".format(unsafe_filter)

        ldap_connection = ldap.initialize("ldap://127.0.0.1")
        user = ldap_connection.search_s(
            dn, ldap.SCOPE_SUBTREE, search_filter)

    ```

    ```python
    from flask import request, Flask
    import ldap3


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        dn = "dc={}".format(unsafe_dc)
        search_filter = "(user={})".format(unsafe_filter)

        srv = ldap3.Server('ldap://127.0.0.1')
        conn = ldap3.Connection(srv, user=dn, auto_bind=True)
        conn.search(dn, search_filter)

    ```
    In the third and fourth example, the input provided by the user is sanitized before it is included in the search filter or DN. This ensures the meaning of the query cannot be changed by a malicious user.


    ```python
    from flask import request, Flask
    import ldap
    import ldap.filter
    import ldap.dn


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        safe_dc = ldap.dn.escape_dn_chars(unsafe_dc)
        safe_filter = ldap.filter.escape_filter_chars(unsafe_filter)

        dn = "dc={}".format(safe_dc)
        search_filter = "(user={})".format(safe_filter)

        ldap_connection = ldap.initialize("ldap://127.0.0.1")
        user = ldap_connection.search_s(
            dn, ldap.SCOPE_SUBTREE, search_filter)

    ```

    ```python
    from flask import request, Flask
    import ldap3
    from ldap3.utils.dn import escape_rdn
    from ldap3.utils.conv import escape_filter_chars


    @app.route("/normal")
    def normal():
        unsafe_dc = request.args['dc']
        unsafe_filter = request.args['username']

        safe_dc = escape_rdn(unsafe_dc)
        safe_filter = escape_filter_chars(unsafe_filter)

        dn = "dc={}".format(safe_dc)
        search_filter = "(user={})".format(safe_filter)

        srv = ldap3.Server('ldap://127.0.0.1')
        conn = ldap3.Connection(srv, user=dn, auto_bind=True)
        conn.search(dn, search_filter)

    # Code injection
    Directly evaluating user input (for example, an HTTP request parameter) as code without properly sanitizing the input first allows an attacker arbitrary code execution. This can occur when user input is passed to code that interprets it as an expression to be evaluated, such as `eval` or `exec`.


    ## Recommendation
    Avoid including user input in any expression that may be dynamically evaluated. If user input must be included, use context-specific escaping before including it. It is important that the correct escaping is used for the type of evaluation that will occur.


    ## Example
    The following example shows two functions setting a name from a request. The first function uses `exec` to execute the `setname` function. This is dangerous as it can allow a malicious user to execute arbitrary code on the server. For example, the user could supply the value `"' + subprocess.call('rm -rf') + '"` to destroy the server's file system. The second function calls the `setname` function directly and is thus safe.


    ```python

    urlpatterns = [
        # Route to code_execution
        url(r'^code-ex1$', code_execution_bad, name='code-execution-bad'),
        url(r'^code-ex2$', code_execution_good, name='code-execution-good')
    ]

    def code_execution(request):
        if request.method == 'POST':
            first_name = base64.decodestring(request.POST.get('first_name', ''))
            #BAD -- Allow user to define code to be run.
            exec("setname('%s')" % first_name)

    def code_execution(request):
        if request.method == 'POST':
            first_name = base64.decodestring(request.POST.get('first_name', ''))
            #GOOD --Call code directly
            setname(first_name)

    ```

    # Log Injection
    If unsanitized user input is written to a log entry, a malicious user may be able to forge new log entries.

    Forgery can occur if a user provides some input with characters that are interpreted when the log output is displayed. If the log is displayed as a plain text file, then new line characters can be used by a malicious user to create the appearance of multiple log entries. If the log is displayed as HTML, then arbitrary HTML may be included to spoof log entries.


    ## Recommendation
    User input should be suitably sanitized before it is logged.

    If the log entries are plain text then line breaks should be removed from user input, using for example `replace(old, new)` or similar. Care should also be taken that user input is clearly marked in log entries, and that a malicious user cannot cause confusion in other ways.

    For log entries that will be displayed in HTML, user input should be HTML encoded before being logged, to prevent forgery and other forms of HTML injection.


    ## Example
    In the example, the name provided by the user is recorded using the log output function (`logging.info` or `app.logger.info`, etc.). In these four cases, the name provided by the user is not provided The processing is recorded. If a malicious user provides `Guest%0D%0AUser name: Admin` as a parameter, the log entry will be divided into two lines, the first line is `User name: Guest` code&gt;, the second line is `User name: Admin`.

    @app.route('/bad1')
    def bad1():
        name = request.args.get('name')
        app.logger.info('User name: ' + name) # Bad
        return 'bad1'

    @app.route('/bad2')
    def bad2():

        app.debug = True
        handler = logging.FileHandler('log')
        app.logger.addHandler(handler)
        app.run()

    ```
    In a good example, the program uses the `replace` function to provide parameter processing to the user, and replace `\r\n` and `\n` with empty characters. To a certain extent, the occurrence of log injection vulnerabilities is reduced.

    # Information exposure through an exception
    Software developers often add stack traces to error messages, as a debugging aid. Whenever that error message occurs for an end user, the developer can use the stack trace to help identify how to fix the problem. In particular, stack traces can tell the developer more about the sequence of events that led to a failure, as opposed to merely the final state of the software when the error occurred.

    Unfortunately, the same information can be useful to an attacker. The sequence of class names in a stack trace can reveal the structure of the application as well as any internal components it relies on. Furthermore, the error message at the top of a stack trace can include information such as server-side file names and SQL code that the application relies on, allowing an attacker to fine-tune a subsequent injection attack.


    ## Recommendation
    Send the user a more generic error message that reveals less information. Either suppress the stack trace entirely, or log it only on the server.


    ## Example
    In the following example, an exception is handled in two different ways. In the first version, labeled BAD, the exception is sent back to the remote user by returning it from the function. As such, the user is able to see a detailed stack trace, which may contain sensitive information. In the second version, the error message is logged only on the server, and a generic error message is displayed to the user. That way, the developers can still access and use the error log, but remote users will not see the information.


    ```python
    from flask import Flask
    app = Flask(__name__)


    import traceback

    def do_computation():
        raise Exception("Secret info")

    # BAD
    @app.route('/bad')
    def server_bad():
        try:
            do_computation()
        except Exception as e:
            return traceback.format_exc()

    # GOOD
    @app.route('/good')
    def server_good():
        try:
            do_computation()
        except Exception as e:
            log(traceback.format_exc())
            return "An internal error has occurred!"

    ```

    Running the following code starts a Flask webserver that has debugging enabled. By visiting `/crash`, it is possible to gain access to the debugger, and run arbitrary code through the interactive debugger.


    ```python
    from flask import Flask

    app = Flask(__name__)

    @app.route('/crash')
    def main():
        raise Exception()

    app.run(debug=True)

    ```

    # PAM authorization bypass due to incorrect usage
    Using only a call to `pam_authenticate` to check the validity of a login can lead to authorization bypass vulnerabilities.

    A `pam_authenticate` only verifies the credentials of a user. It does not check if a user has an appropriate authorization to actually login. This means a user with an expired login or a password can still access the system.


    ## Recommendation
    A call to `pam_authenticate` should be followed by a call to `pam_acct_mgmt` to check if a user is allowed to login.


    ## Example
    In the following example, the code only checks the credentials of a user. Hence, in this case, a user with expired credentials can still login. This can be verified by creating a new user account, expiring it with ``` chage -E0 `username`  ``` and then trying to log in.


    ```python
    libpam                    = CDLL(find_library("pam"))

    pam_authenticate          = libpam.pam_authenticate
    pam_authenticate.restype  = c_int
    pam_authenticate.argtypes = [PamHandle, c_int]

    def authenticate(username, password, service='login'):
        def my_conv(n_messages, messages, p_response, app_data):
            """
            Simple conversation function that responds to any prompt where the echo is off with the supplied password
            """
            ...

        handle = PamHandle()
        conv   = PamConv(my_conv, 0)
        retval = pam_start(service, username, byref(conv), byref(handle))

        retval = pam_authenticate(handle, 0)
        return retval == 0

    ```
    This can be avoided by calling `pam_acct_mgmt` call to verify access as has been done in the snippet shown below.


    ```python
    libpam                    = CDLL(find_library("pam"))

    pam_authenticate          = libpam.pam_authenticate
    pam_authenticate.restype  = c_int
    pam_authenticate.argtypes = [PamHandle, c_int]

    pam_acct_mgmt          = libpam.pam_acct_mgmt
    pam_acct_mgmt.restype  = c_int
    pam_acct_mgmt.argtypes = [PamHandle, c_int]

    def authenticate(username, password, service='login'):
        def my_conv(n_messages, messages, p_response, app_data):
            """
            Simple conversation function that responds to any prompt where the echo is off with the supplied password
            """
            ...

        handle = PamHandle()
        conv   = PamConv(my_conv, 0)
        retval = pam_start(service, username, byref(conv), byref(handle))

        retval = pam_authenticate(handle, 0)
        if retval == 0:
            retval = pam_acct_mgmt(handle, 0)
        return retval == 0

    ```

    # Accepting unknown SSH host keys when using Paramiko
    In the Secure Shell (SSH) protocol, host keys are used to verify the identity of remote hosts. Accepting unknown host keys may leave the connection open to man-in-the-middle attacks.


    ## Recommendation
    Do not accept unknown host keys. In particular, do not set the default missing host key policy for the Paramiko library to either `AutoAddPolicy` or `WarningPolicy`. Both of these policies continue even when the host key is unknown. The default setting of `RejectPolicy` is secure because it throws an exception when it encounters an unknown host key.


    ## Example
    The following example shows two ways of opening an SSH connection to `example.com`. The first function sets the missing host key policy to `AutoAddPolicy`. If the host key verification fails, the client will continue to interact with the server, even though the connection may be compromised. The second function sets the host key policy to `RejectPolicy`, and will throw an exception if the host key verification fails.


    ```python
    from paramiko.client import SSHClient, AutoAddPolicy, RejectPolicy

    def unsafe_connect():
        client = SSHClient()
        client.set_missing_host_key_policy(AutoAddPolicy)
        client.connect("example.com")

        # ... interaction with server

        client.close()

    def safe_connect():
        client = SSHClient()
        client.set_missing_host_key_policy(RejectPolicy)
        client.connect("example.com")

        # ... interaction with server

        client.close()

    ```

    # Request without certificate validation
    Encryption is key to the security of most, if not all, online communication. Using Transport Layer Security (TLS) can ensure that communication cannot be interrupted by an interloper. For this reason, it is unwise to disable the verification that TLS provides. Functions in the `requests` module provide verification by default, and it is only when explicitly turned off using `verify=False` that no verification occurs.


    ## Recommendation
    Never use `verify=False` when making a request.


    ## Example
    The example shows two unsafe calls to [semmle.com](https://semmle.com), followed by various safe alternatives.


    ```python
    import requests

    #Unsafe requests

    requests.get('https://semmle.com', verify=False) # UNSAFE
    requests.get('https://semmle.com', verify=0) # UNSAFE

    #Various safe options

    requests.get('https://semmle.com', verify=True) # Explicitly safe
    requests.get('https://semmle.com', verify="/path/to/cert/")
    requests.get('https://semmle.com') # The default is to verify.

    #Wrapper to ensure safety

    def make_safe_request(url, verify_cert):
        if not verify_cert:
            raise Exception("Trying to make unsafe request")
        return requests.get(url, verify_cert)

    # Clear-text logging of sensitive information
    If sensitive data is written to a log entry it could be exposed to an attacker who gains access to the logs.

    Potential attackers can obtain sensitive user data when the log output is displayed. Additionally that data may expose system information such as full path names, system information, and sometimes usernames and passwords.


    ## Recommendation
    Sensitive data should not be logged.


    ## Example
    In the example the entire process environment is logged using \`print\`. Regular users of the production deployed application should not have access to this much information about the environment configuration.


    ```python
    # BAD: Logging cleartext sensitive data
    import os
    print(f"[INFO] Environment: {os.environ}")
    ```
    In the second example the data that is logged is not sensitive.


    ```python
    not_sensitive_data = {'a': 1, 'b': 2}
    # GOOD: it is fine to log data that is not sensitive
    print(f"[INFO] Some object contains: {not_sensitive_data}")

    # Clear-text storage of sensitive information
    Sensitive information that is stored unencrypted is accessible to an attacker who gains access to the storage. This is particularly important for cookies, which are stored on the machine of the end-user.


    ## Recommendation
    Ensure that sensitive information is always encrypted before being stored. If possible, avoid placing sensitive information in cookies altogether. Instead, prefer storing, in the cookie, a key that can be used to look up the sensitive information.

    In general, decrypt sensitive information only at the point where it is necessary for it to be used in cleartext.

    Be aware that external processes often store the `standard out` and `standard error` streams of the application, causing logged sensitive information to be stored as well.


    ## Example
    The following example code stores user credentials (in this case, their password) in a cookie in plain text:


    ```python
    from flask import Flask, make_response, request

    app = Flask("Leak password")

    @app.route('/')
    def index():
        password = request.args.get("password")
        resp = make_response(render_template(...))
        resp.set_cookie("password", password)
        return resp

    ```
    Instead, the credentials should be encrypted, for instance by using the `cryptography` module, or not stored at all.

    # Use of weak cryptographic key
    Modern encryption relies on it being computationally infeasible to break the cipher and decode a message without the key. As computational power increases, the ability to break ciphers grows and keys need to become larger.

    The three main asymmetric key algorithms currently in use are Rivest–Shamir–Adleman (RSA) cryptography, Digital Signature Algorithm (DSA), and Elliptic-curve cryptography (ECC). With current technology, key sizes of 2048 bits for RSA and DSA, or 256 bits for ECC, are regarded as unbreakable.


    ## Recommendation
    Increase the key size to the recommended amount or larger. For RSA or DSA this is at least 2048 bits, for ECC this is at least 256 bits.

    # Use of a broken or weak cryptographic algorithm
    Using broken or weak cryptographic algorithms may compromise security guarantees such as confidentiality, integrity, and authenticity.

    Many cryptographic algorithms are known to be weak or flawed. The security guarantees of a system often rely on the underlying cryptography, so using a weak algorithm can have severe consequences. For example:

    * If a weak encryption algorithm is used, an attacker may be able to decrypt sensitive data.
    * If a weak algorithm is used for digital signatures, an attacker may be able to forge signatures and impersonate legitimate users.
    This query alerts on any use of a weak cryptographic algorithm that is not a hashing algorithm. Use of broken or weak cryptographic hash functions are handled by the `py/weak-sensitive-data-hashing` query.


    ## Recommendation
    Ensure that you use a strong, modern cryptographic algorithm, such as AES-128 or RSA-2048.


    ## Example
    The following code uses the `pycryptodome` library to encrypt some secret data. When you create a cipher using `pycryptodome` you must specify the encryption algorithm to use. The first example uses DES, which is an older algorithm that is now considered weak. The second example uses AES, which is a stronger modern algorithm.


    ```python
    from Crypto.Cipher import DES, AES

    cipher = DES.new(SECRET_KEY)

    def send_encrypted(channel, message):
        channel.send(cipher.encrypt(message)) # BAD: weak encryption


    cipher = AES.new(SECRET_KEY)

    def send_encrypted(channel, message):
        channel.send(cipher.encrypt(message)) # GOOD: strong encryption


    ```
    NOTICE: the original `[pycrypto](https://pypi.org/project/pycrypto/)` PyPI package that provided the `Crypto` module is not longer actively maintained, so you should use the `[pycryptodome](https://pypi.org/project/pycryptodome/)` PyPI package instead (which has a compatible API).

    # Default version of SSL/TLS may be insecure
    The `ssl.wrap_socket` function defaults to an insecure version of SSL/TLS when no specific protocol version is specified. This may leave the connection vulnerable to attack.


    ## Recommendation
    Ensure that a modern, strong protocol is used. All versions of SSL, and TLS 1.0 and 1.1 are known to be vulnerable to attacks. Using TLS 1.2 or above is strongly recommended. If no explicit `ssl_version` is specified, the default `PROTOCOL_TLS` is chosen. This protocol is insecure because it allows TLS 1.0 and TLS 1.1 and so should not be used.


    ## Example
    The following code shows two different ways of setting up a connection using SSL or TLS. They are both potentially insecure because the default version is used.


    ```python
    import ssl
    import socket

    # Using the deprecated ssl.wrap_socket method
    ssl.wrap_socket(socket.socket())

    # Using SSLContext
    context = ssl.SSLContext()

    ```
    Both of the cases above should be updated to use a secure protocol instead, for instance by specifying `ssl_version=PROTOCOL_TLSv1_2` as a keyword argument.

    The latter example can also be made secure by modifying the created context before it is used to create a connection. Therefore it will not be flagged by this query. However, if a connection is created before the context has been secured (for example, by setting the value of `minimum_version`), then the code should be flagged by the query `py/insecure-protocol`.

    Note that `ssl.wrap_socket` has been deprecated in Python 3.7. The recommended alternatives are:

    * `ssl.SSLContext` - supported in Python 2.7.9, 3.2, and later versions
    * `ssl.create_default_context` - a convenience function, supported in Python 3.4 and later versions.
    Even when you use these alternatives, you should ensure that a safe protocol is used. The following code illustrates how to use flags (available since Python 3.2) or the \`minimum_version\` field (favored since Python 3.7) to restrict the protocols accepted when creating a connection.


    ```python
    import ssl

    # Using flags to restrict the protocol
    context = ssl.SSLContext()
    context.options |= ssl.OP_NO_TLSv1 | ssl.OP_NO_TLSv1_1

    # Declaring a minimum version to restrict the protocol
    context = ssl.create_default_context()
    context.minimum_version = ssl.TLSVersion.TLSv1_2

    ```

    # Use of a broken or weak cryptographic hashing algorithm on sensitive data
    Using a broken or weak cryptographic hash function can leave data vulnerable, and should not be used in security related code.

    A strong cryptographic hash function should be resistant to:

    * pre-image attacks: if you know a hash value `h(x)`, you should not be able to easily find the input `x`.
    * collision attacks: if you know a hash value `h(x)`, you should not be able to easily find a different input `y` with the same hash value `h(x) = h(y)`.
    In cases with a limited input space, such as for passwords, the hash function also needs to be computationally expensive to be resistant to brute-force attacks. Passwords should also have an unique salt applied before hashing, but that is not considered by this query.

    As an example, both MD5 and SHA-1 are known to be vulnerable to collision attacks.

    Since it's OK to use a weak cryptographic hash function in a non-security context, this query only alerts when these are used to hash sensitive data (such as passwords, certificates, usernames).

    Use of broken or weak cryptographic algorithms that are not hashing algorithms, is handled by the `py/weak-cryptographic-algorithm` query.


    ## Recommendation
    Ensure that you use a strong, modern cryptographic hash function:

    * such as Argon2, scrypt, bcrypt, or PBKDF2 for passwords and other data with limited input space.
    * such as SHA-2, or SHA-3 in other cases.

    ## Example
    The following example shows two functions for checking whether the hash of a certificate matches a known value -- to prevent tampering. The first function uses MD5 that is known to be vulnerable to collision attacks. The second function uses SHA-256 that is a strong cryptographic hashing function.


    ```python
    import hashlib

    def certificate_matches_known_hash_bad(certificate, known_hash):
        hash = hashlib.md5(certificate).hexdigest() # BAD
        return hash == known_hash

    def certificate_matches_known_hash_good(certificate, known_hash):
        hash = hashlib.sha256(certificate).hexdigest() # GOOD
        return hash == known_hash

    ```

    ## Example
    The following example shows two functions for hashing passwords. The first function uses SHA-256 to hash passwords. Although SHA-256 is a strong cryptographic hash function, it is not suitable for password hashing since it is not computationally expensive.


    ```python
    import hashlib

    def get_password_hash(password: str, salt: str):
        return hashlib.sha256(password + salt).hexdigest() # BAD

    ```
    The second function uses Argon2 (through the `argon2-cffi` PyPI package), which is a strong password hashing algorithm (and includes a per-password salt by default).


    ```python
    from argon2 import PasswordHasher

    def get_initial_hash(password: str):
        ph = PasswordHasher()
        return ph.hash(password) # GOOD

    def check_password(password: str, known_hash):
        ph = PasswordHasher()
        return ph.verify(known_hash, password) # GOOD

    ```

    # CSRF protection weakened or disabled
    Cross-site request forgery (CSRF) is a type of vulnerability in which an attacker is able to force a user to carry out an action that the user did not intend.

    The attacker tricks an authenticated user into submitting a request to the web application. Typically this request will result in a state change on the server, such as changing the user's password. The request can be initiated when the user visits a site controlled by the attacker. If the web application relies only on cookies for authentication, or on other credentials that are automatically included in the request, then this request will appear as legitimate to the server.

    A common countermeasure for CSRF is to generate a unique token to be included in the HTML sent from the server to a user. This token can be used as a hidden field to be sent back with requests to the server, where the server can then check that the token is valid and associated with the relevant user session.


    ## Recommendation
    In many web frameworks, CSRF protection is enabled by default. In these cases, using the default configuration is sufficient to guard against most CSRF attacks.


    ## Example
    The following example shows a case where CSRF protection is disabled by overriding the default middleware stack and not including the one protecting against CSRF.


    ```python
    MIDDLEWARE = [
        'django.middleware.security.SecurityMiddleware',
        'django.contrib.sessions.middleware.SessionMiddleware',
        'django.middleware.common.CommonMiddleware',
        # 'django.middleware.csrf.CsrfViewMiddleware',
        'django.contrib.auth.middleware.AuthenticationMiddleware',
        'django.contrib.messages.middleware.MessageMiddleware',
        'django.middleware.clickjacking.XFrameOptionsMiddleware',
    ]

    ```
    The protecting middleware was probably commented out during a testing phase, when server-side token generation was not set up. Simply commenting it back in will enable CSRF protection.

    # Insecure temporary file
    Functions that create temporary file names (such as `tempfile.mktemp` and `os.tempnam`) are fundamentally insecure, as they do not ensure exclusive access to a file with the temporary name they return. The file name returned by these functions is guaranteed to be unique on creation but the file must be opened in a separate operation. There is no guarantee that the creation and open operations will happen atomically. This provides an opportunity for an attacker to interfere with the file before it is opened.

    Note that `mktemp` has been deprecated since Python 2.3.


    ## Recommendation
    Replace the use of `mktemp` with some of the more secure functions in the `tempfile` module, such as `TemporaryFile`. If the file is intended to be accessed from other processes, consider using the `NamedTemporaryFile` function.


    ## Example
    The following piece of code opens a temporary file and writes a set of results to it. Because the file name is created using `mktemp`, another process may access this file before it is opened using `open`.


    ```python
    from tempfile import mktemp

    def write_results(results):
        filename = mktemp()
        with open(filename, "w+") as f:
            f.write(results)
        print("Results written to", filename)

    ```
    By changing the code to use `NamedTemporaryFile` instead, the file is opened immediately.


    ```python
    from tempfile import NamedTemporaryFile

    def write_results(results):
        with NamedTemporaryFile(mode="w+", delete=False) as f:
            f.write(results)
        print("Results written to", f.name)

    ```

    # Deserialization of user-controlled data
    Deserializing untrusted data using any deserialization framework that allows the construction of arbitrary serializable objects is easily exploitable and in many cases allows an attacker to execute arbitrary code. Even before a deserialized object is returned to the caller of a deserialization method a lot of code may have been executed, including static initializers, constructors, and finalizers. Automatic deserialization of fields means that an attacker may craft a nested combination of objects on which the executed initialization code may have unforeseen effects, such as the execution of arbitrary code.

    There are many different serialization frameworks. This query currently supports Pickle, Marshal and Yaml.


    ## Recommendation
    Avoid deserialization of untrusted data if at all possible. If the architecture permits it then use other formats instead of serialized objects, for example JSON.

    If you need to use YAML, use the `yaml.safe_load` function.


    ## Example
    The following example calls `pickle.loads` directly on a value provided by an incoming HTTP request. Pickle then creates a new value from untrusted data, and is therefore inherently unsafe.


    ```python

    from django.conf.urls import url
    import pickle

    def unsafe(pickled):
        return pickle.loads(pickled)

    urlpatterns = [
        url(r'^(?P<object>.*)$', unsafe)
    ]
    ```
    Changing the code to use `json.loads` instead of `pickle.loads` removes the vulnerability.


    ```python

    from django.conf.urls import url
    import json

    def safe(pickled):
        return json.loads(pickled)

    urlpatterns = [
        url(r'^(?P<object>.*)$', safe)
    ]

    ```

    # URL redirection from remote source
    Directly incorporating user input into a URL redirect request without validating the input can facilitate phishing attacks. In these attacks, unsuspecting users can be redirected to a malicious site that looks very similar to the real site they intend to visit, but which is controlled by the attacker.


    ## Recommendation
    To guard against untrusted URL redirection, it is advisable to avoid putting user input directly into a redirect URL. Instead, maintain a list of authorized redirects on the server; then choose from that list based on the user input provided.

    If this is not possible, then the user input should be validated in some other way, for example, by verifying that the target URL does not include an explicit host name.


    ## Example
    The following example shows an HTTP request parameter being used directly in a URL redirect without validating the input, which facilitates phishing attacks:


    ```python
    from flask import Flask, request, redirect

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        return redirect(target, code=302)

    ```
    If you know the set of valid redirect targets, you can maintain a list of them on the server and check that the user input is in that list:


    ```python
    from flask import Flask, request, redirect

    VALID_REDIRECT = "http://cwe.mitre.org/data/definitions/601.html"

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        if target == VALID_REDIRECT:
            return redirect(target, code=302)
        else:
            # ignore the target and redirect to the home page
            return redirect('/', code=302)

    ```
    Often this is not possible, so an alternative is to check that the target URL does not specify an explicit host name. For example, you can use the `urlparse` function from the Python standard library to parse the URL and check that the `netloc` attribute is empty.

    Note, however, that some cases are not handled as we desire out-of-the-box by `urlparse`, so we need to adjust two things, as shown in the example below:

    * Many browsers accept backslash characters (`\`) as equivalent to forward slash characters (`/`) in URLs, but the `urlparse` function does not.
    * Mistyped URLs such as `https:/example.com` or `https:///example.com` are parsed as having an empty `netloc` attribute, while browsers will still redirect to the correct site.

    ```python
    from flask import Flask, request, redirect
    from urllib.parse import urlparse

    app = Flask(__name__)

    @app.route('/')
    def hello():
        target = request.args.get('target', '')
        target = target.replace('\\', '')
        if not urlparse(target).netloc and not urlparse(target).scheme:
            # relative path, safe to redirect
            return redirect(target, code=302)
        # ignore the target and redirect to the home page
        return redirect('/', code=302)

    ```
    For Django application, you can use the function `url_has_allowed_host_and_scheme` to check that a URL is safe to redirect to, as shown in the following example:


    ```python
    from django.http import HttpResponseRedirect
    from django.shortcuts import redirect
    from django.utils.http import url_has_allowed_host_and_scheme
    from django.views import View

    class RedirectView(View):
        def get(self, request, *args, **kwargs):
            target = request.GET.get('target', '')
            if url_has_allowed_host_and_scheme(target, allowed_hosts=None):
                return HttpResponseRedirect(target)
            else:
                # ignore the target and redirect to the home page
                return redirect('/')
    ```
    Note that `url_has_allowed_host_and_scheme` handles backslashes correctly, so no additional processing is required.

    # XML external entity expansion
    Parsing untrusted XML files with a weakly configured XML parser may lead to an XML External Entity (XXE) attack. This type of attack uses external entity references to access arbitrary files on a system, carry out denial-of-service (DoS) attacks, or server-side request forgery. Even when the result of parsing is not returned to the user, DoS attacks are still possible and out-of-band data retrieval techniques may allow attackers to steal sensitive data.


    ## Recommendation
    The easiest way to prevent XXE attacks is to disable external entity handling when parsing untrusted data. How this is done depends on the library being used. Note that some libraries, such as recent versions of the XML libraries in the standard library of Python 3, disable entity expansion by default, so unless you have explicitly enabled entity expansion, no further action needs to be taken.

    We recommend using the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package, which has been created to prevent XML attacks (both XXE and XML bombs).


    ## Example
    The following example uses the `lxml` XML parser to parse a string `xml_src`. That string is from an untrusted source, so this code is vulnerable to an XXE attack, since the [ default parser](https://lxml.de/apidoc/lxml.etree.html#lxml.etree.XMLParser) from `lxml.etree` allows local external entities to be resolved.


    ```python
    from flask import Flask, request
    import lxml.etree

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = lxml.etree.fromstring(xml_src)
        return lxml.etree.tostring(doc)

    ```
    To guard against XXE attacks with the `lxml` library, you should create a parser with `resolve_entities` set to `false`. This means that no entity expansion is undertaken, although standard predefined entities such as `&gt;`, for writing `>` inside the text of an XML element, are still allowed.


    ```python
    from flask import Flask, request
    import lxml.etree

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        parser = lxml.etree.XMLParser(resolve_entities=False)
        doc = lxml.etree.fromstring(xml_src, parser=parser)
        return lxml.etree.tostring(doc)

    ```

    # XPath query built from user-controlled sources
    If an XPath expression is built using string concatenation, and the components of the concatenation include user input, it makes it very easy for a user to create a malicious XPath expression.


    ## Recommendation
    If user input must be included in an XPath expression, either sanitize the data or use variable references to safely embed it without altering the structure of the expression.


    ## Example
    In the example below, the xpath query is controlled by the user and hence leads to a vulnerability.


    ```python
    from lxml import etree
    from io import StringIO

    from django.urls import path
    from django.http import HttpResponse
    from django.template import Template, Context, Engine, engines


    def a(request):
        value = request.GET['xpath']
        f = StringIO('<foo><bar></bar></foo>')
        tree = etree.parse(f)
        r = tree.xpath("/tag[@id='%s']" % value)


    urlpatterns = [
        path('a', a)
    ]

    ```
    This can be fixed by using a parameterized query as shown below.


    ```python
    from lxml import etree
    from io import StringIO

    from django.urls import path
    from django.http import HttpResponse
    from django.template import Template, Context, Engine, engines


    def a(request):
        value = request.GET['xpath']
        f = StringIO('<foo><bar></bar></foo>')
        tree = etree.parse(f)
        r = tree.xpath("/tag[@id=$tagid]", tagid=value)


    urlpatterns = [
        path('a', a)
    ]

    ```

    \nThe regular expression engine provided by Python uses a backtracking non-deterministic\

    \ is space-efficient and allows supporting advanced features like capture groups,\
    \ it is not time-efficient in general. The worst-case time complexity of such\

    \ in the references.\n\n\n## Recommendation\nModify the regular expression to\
    \ remove the ambiguity, or ensure that the strings matched with the regular expression\
    \ are short enough that the time-complexity does not matter.\n\n\n## Example\n\
    Consider this use of a regular expression, which removes all leading and trailing\
    \ whitespace in a string:\n\n```python\n\nre.sub(r\"^\\s+|\\s+$\", \"\", text)\
    \ # BAD\n```\nThe sub-expression `\"\\s+$\"` will match the whitespace characters\
    \ in `text` from left to right, but it can start matching anywhere within a whitespace\
    \ sequence. This is problematic for strings that do **not** end with a whitespace\
    \ character. Such a string will force the regular expression engine to process\
    \ each whitespace sequence once per whitespace character in the sequence.\n\n\
    This ultimately means that the time cost of trimming a string is quadratic in\
    \ the length of the string. So a string like `\"a b\"` will take milliseconds\
    \ to process, but a similar string with a million spaces instead of just one will\
    \ take several minutes.\n\nAvoid this problem by rewriting the regular expression\
    \ to not contain the ambiguity about when to start matching whitespace sequences.\
    \ For instance, by using a negative look-behind (`^\\s+|(?<!\\s)\\s+$`), or just\
    \ by using the built-in strip method (`text.strip()`).\n\nNote that the sub-expression\
    \ `\"^\\s+\"` is **not** problematic as the `^` anchor restricts when that sub-expression\
    \ can start matching, and as the regular expression engine matches from left to\
    \ right.\n\n\n## Example\nAs a similar, but slightly subtler problem, consider\
    \ the regular expression that matches lines with numbers, possibly written using\
    \ scientific notation:\n\n```python\n\n^0\\.\\d+E?\\d+$ # BAD\n```\nThe problem\
    \ with this regular expression is in the sub-expression `\\d+E?\\d+` because the\
    \ second `\\d+` can start matching digits anywhere after the first match of the\
    \ first `\\d+` if there is no `E` in the input string.\n\nThis is problematic\
    \ for strings that do **not** end with a digit. Such a string will force the regular\
    \ expression engine to process each digit sequence once per digit in the sequence,\
    \ again leading to a quadratic time complexity.\n\nTo make the processing faster,\
    \ the regular expression should be rewritten such that the two `\\d+` sub-expressions\
    \ do not have overlapping matches: `^0\\.\\d+(E\\d+)?$`.\n\n\n## Example\nSometimes\
    \ it is unclear how a regular expression can be rewritten to avoid the problem.\
    \ In such cases, it often suffices to limit the length of the input string. For\
    \ instance, the following regular expression is used to match numbers, and on\
    \ some non-number inputs it can have quadratic time complexity:\n\n```python\n\
    \nmatch = re.search(r'^(\\+|-)?(\\d+|(\\d*\\.\\d*))?(E|e)?([-+])?(\\d+)?$', str)\
    \ \n```\nIt is not immediately obvious how to rewrite this regular expression\
    \ to avoid the problem. However, you can mitigate performance issues by limiting\
    \ the length to 1000 characters, which will always finish in a reasonable amount\
    \ of time.\n\n```python\n\nif len(str) > 1000:\n    raise ValueError(\"Input too\
    \ long\")\n\nmatch = re.search(r'^(\\+|-)?(\\d+|(\\d*\\.\\d*))?(E|e)?([-+])?(\\\
    d+)?$', str) \n```\n\n## References\n* OWASP: [Regular expression Denial of Service\

    # Inefficient regular expression
    Some regular expressions take a long time to match certain input strings to the point where the time it takes to match a string of length *n* is proportional to *n<sup>k</sup>* or even *2<sup>n</sup>*. Such regular expressions can negatively affect performance, or even allow a malicious user to perform a Denial of Service ("DoS") attack by crafting an expensive input string for the regular expression to match.

More information about the precise circumstances can be found in the references.


    ## Recommendation
    Modify the regular expression to remove the ambiguity, or ensure that the strings matched with the regular expression are short enough that the time-complexity does not matter.


    ## Example
    Consider this regular expression:

    ```python

    ^_(__|.)+_$
    ```
    Its sub-expression `"(__|.)+?"` can match the string `"__"` either by the first alternative `"__"` to the left of the `"|"` operator, or by two repetitions of the second alternative `"."` to the right. Thus, a string consisting of an odd number of underscores followed by some other character will cause the regular expression engine to run for an exponential amount of time before rejecting the input.

    This problem can be avoided by rewriting the regular expression to remove the ambiguity between the two branches of the alternative inside the repetition:

    ```python

    ^_(__|[^_])+_$
    ```

    # Regular expression injection
    Constructing a regular expression with unsanitized user input is dangerous as a malicious user may be able to modify the meaning of the expression. In particular, such a user may be able to provide a regular expression fragment that takes exponential time in the worst case, and use that to perform a Denial of Service attack.


    ## Recommendation
    Before embedding user input into a regular expression, use a sanitization function such as `re.escape` to escape meta-characters that have a special meaning regarding regular expressions' syntax.


    ## Example
    The following examples are based on a simple Flask web server environment.

    The following example shows a HTTP request parameter that is used to construct a regular expression without sanitizing it first:


    ```python
    from flask import request, Flask
    import re


    @app.route("/direct")
    def direct():
        unsafe_pattern = request.args["pattern"]
        re.search(unsafe_pattern, "")


    @app.route("/compile")
    def compile():
        unsafe_pattern = request.args["pattern"]
        compiled_pattern = re.compile(unsafe_pattern)
        compiled_pattern.search("")

    ```
    Instead, the request parameter should be sanitized first, for example using the function `re.escape`. This ensures that the user cannot insert characters which have a special meaning in regular expressions.


    ```python
    from flask import request, Flask
    import re


    @app.route("/direct")
    def direct():
        unsafe_pattern = request.args['pattern']
        safe_pattern = re.escape(unsafe_pattern)
        re.search(safe_pattern, "")


    @app.route("/compile")
    def compile():
        unsafe_pattern = request.args['pattern']
        safe_pattern = re.escape(unsafe_pattern)
        compiled_pattern = re.compile(safe_pattern)
        compiled_pattern.search("")

    ```

    # XML internal entity expansion
    Parsing untrusted XML files with a weakly configured XML parser may be vulnerable to denial-of-service (DoS) attacks exploiting uncontrolled internal entity expansion.

    In XML, so-called *internal entities* are a mechanism for introducing an abbreviation for a piece of text or part of a document. When a parser that has been configured to expand entities encounters a reference to an internal entity, it replaces the entity by the data it represents. The replacement text may itself contain other entity references, which are expanded recursively. This means that entity expansion can increase document size dramatically.

    If untrusted XML is parsed with entity expansion enabled, a malicious attacker could submit a document that contains very deeply nested entity definitions, causing the parser to take a very long time or use large amounts of memory. This is sometimes called an *XML bomb* attack.


    ## Recommendation
    The safest way to prevent XML bomb attacks is to disable entity expansion when parsing untrusted data. Whether this can be done depends on the library being used. Note that some libraries, such as `lxml`, have measures enabled by default to prevent such DoS XML attacks, so unless you have explicitly set `huge_tree` to `True`, no further action is needed.

    We recommend using the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package, which has been created to prevent XML attacks (both XXE and XML bombs).


    ## Example
    The following example uses the `xml.etree` XML parser provided by the Python standard library to parse a string `xml_src`. That string is from an untrusted source, so this code is vulnerable to a DoS attack, since the `xml.etree` XML parser expands internal entities by default:


    ```python
    from flask import Flask, request
    import xml.etree.ElementTree as ET

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = ET.fromstring(xml_src)
        return ET.tostring(doc)

    ```
    It is not possible to guard against internal entity expansion with `xml.etree`, so to guard against these attacks, the following example uses the [defusedxml](https://pypi.org/project/defusedxml/) PyPI package instead, which is not exposed to such internal entity expansion attacks.


    ```python
    from flask import Flask, request
    import defusedxml.ElementTree as ET

    app = Flask(__name__)

    @app.post("/upload")
    def upload():
        xml_src = request.get_data()
        doc = ET.fromstring(xml_src)
        return ET.tostring(doc)

    ```

    # Full server-side request forgery
    Directly incorporating user input into an HTTP request without validating the input can facilitate server-side request forgery (SSRF) attacks. In these attacks, the request may be changed, directed at a different server, or via a different protocol. This can allow the attacker to obtain sensitive information or perform actions with escalated privilege.

    We make a distinctions between how much of the URL an attacker can control:

    * **Full SSRF**: where the full URL can be controlled.
    * **Partial SSRF**: where only part of the URL can be controlled, such as the path component of a URL to a hardcoded domain.


    Partial control of a URL is often much harder to exploit. Therefore we have created a separate query for each of these.

    This query covers full SSRF, to find partial SSRF use the `py/partial-ssrf` query.


    ## Recommendation
    To guard against SSRF attacks you should avoid putting user-provided input directly into a request URL. On the application level, maintain a list of authorized URLs on the server and choose from that list based on the input provided. If that is not possible, one should verify the IP address for all user-controlled requests to ensure they are not private. This requires saving the verified IP address of each domain, then utilizing a custom HTTP adapter to ensure that future requests to that domain use the verified IP address. On the network level, you can segment the vulnerable application into its own LAN or block access to specific devices.


    ## Example
    The following example shows code vulnerable to a full SSRF attack, because it uses untrusted input (HTTP request parameter) directly to construct a URL. By using `evil.com#` as the `target` value, the requested URL will be `https://evil.com#.example.com/data/`. It also shows how to remedy the problem by using the user input select a known fixed string.


    ```python
    import requests
    from flask import Flask, request

    app = Flask(__name__)

    @app.route("/full_ssrf")
    def full_ssrf():
        target = request.args["target"]

        # BAD: user has full control of URL
        resp = requests.get("https://" + target + ".example.com/data/")

        # GOOD: `subdomain` is controlled by the server.
        subdomain = "europe" if target == "EU" else "world"
        resp = requests.get("https://" + subdomain + ".example.com/data/")

    ```

    ## Example
    The following example shows code vulnerable to a partial SSRF attack, because it uses untrusted input (HTTP request parameter) directly to construct a URL. By using `../transfer-funds-to/123?amount=456` as the `user_id` value, the requested URL will be `https://api.example.com/transfer-funds-to/123?amount=456`. It also shows how to remedy the problem by validating the input.


    ```python
    import requests
    from flask import Flask, request

    app = Flask(__name__)

    @app.route("/partial_ssrf")
    def partial_ssrf():
        user_id = request.args["user_id"]

        # BAD: user can fully control the path component of the URL
        resp = requests.get("https://api.example.com/user_info/" + user_id)

        if user_id.isalnum():
            # GOOD: user_id is restricted to be alpha-numeric, and cannot alter path component of URL
            resp = requests.get("https://api.example.com/user_info/" + user_id)

    ```

    # Partial server-side request forgery
    Directly incorporating user input into an HTTP request without validating the input can facilitate server-side request forgery (SSRF) attacks. In these attacks, the request may be changed, directed at a different server, or via a different protocol. This can allow the attacker to obtain sensitive information or perform actions with escalated privilege.

    We make a distinctions between how much of the URL an attacker can control:

    * **Full SSRF**: where the full URL can be controlled.
    * **Partial SSRF**: where only part of the URL can be controlled, such as the path component of a URL to a hardcoded domain.


    Partial control of a URL is often much harder to exploit. Therefore we have created a separate query for each of these.

    This query covers partial SSRF, to find full SSRF use the `py/full-ssrf` query.


    ## Recommendation
    To guard against SSRF attacks you should avoid putting user-provided input directly into a request URL. On the application level, maintain a list of authorized URLs on the server and choose from that list based on the input provided. If that is not possible, one should verify the IP address for all user-controlled requests to ensure they are not private. This requires saving the verified IP address of each domain, then utilizing a custom HTTP adapter to ensure that future requests to that domain use the verified IP address. On the network level, you can segment the vulnerable application into its own LAN or block access to specific devices.


    ## Example
    The following example shows code vulnerable to a full SSRF attack, because it uses untrusted input (HTTP request parameter) directly to construct a URL. By using `evil.com#` as the `target` value, the requested URL will be `https://evil.com#.example.com/data/`. It also shows how to remedy the problem by using the user input select a known fixed string.


    ```python
    import requests
    from flask import Flask, request

    app = Flask(__name__)

    @app.route("/full_ssrf")
    def full_ssrf():
        target = request.args["target"]

        # BAD: user has full control of URL
        resp = requests.get("https://" + target + ".example.com/data/")

        # GOOD: `subdomain` is controlled by the server.
        subdomain = "europe" if target == "EU" else "world"
        resp = requests.get("https://" + subdomain + ".example.com/data/")

    ```

    ## Example
    The following example shows code vulnerable to a partial SSRF attack, because it uses untrusted input (HTTP request parameter) directly to construct a URL. By using `../transfer-funds-to/123?amount=456` as the `user_id` value, the requested URL will be `https://api.example.com/transfer-funds-to/123?amount=456`. It also shows how to remedy the problem by validating the input.


    ```python
    import requests
    from flask import Flask, request

    app = Flask(__name__)

    @app.route("/partial_ssrf")
    def partial_ssrf():
        user_id = request.args["user_id"]

        # BAD: user can fully control the path component of the URL
        resp = requests.get("https://api.example.com/user_info/" + user_id)

        if user_id.isalnum():
            # GOOD: user_id is restricted to be alpha-numeric, and cannot alter path component of URL
            resp = requests.get("https://api.example.com/user_info/" + user_id)

    ```

    # NoSQL Injection
    Passing user-controlled sources into NoSQL queries can result in a NoSQL injection flaw. This tainted NoSQL query containing a user-controlled source can then execute a malicious query in a NoSQL database such as MongoDB. In order for the user-controlled source to taint the NoSQL query, the user-controller source must be converted into a Python object using something like `json.loads` or `xmltodict.parse`.

    Because a user-controlled source is passed into the query, the malicious user can have complete control over the query itself. When the tainted query is executed, the malicious user can commit malicious actions such as bypassing role restrictions or accessing and modifying restricted data in the NoSQL database.


    ## Recommendation
    NoSQL injections can be prevented by escaping user-input's special characters that are passed into the NoSQL query from the user-supplied source. Alternatively, using a sanitize library such as MongoSanitizer will ensure that user-supplied sources can not act as a malicious query.


    ## Example
    In the example below, the user-supplied source is passed to a MongoDB function that queries the MongoDB database.


    ```python
    from flask import Flask, request
    from flask_pymongo import PyMongo
    import json

    mongo = PyMongo(app)


    @app.route("/")
    def home_page():
        unsanitized_search = request.args['search']
        json_search = json.loads(unsanitized_search)

        result = mongo.db.user.find({'name': json_search})

    ```
    This can be fixed by using a sanitizer library like MongoSanitizer as shown in this annotated code version below.


    ```python
    from flask import Flask, request
    from flask_pymongo import PyMongo
    from mongosanitizer.sanitizer import sanitize
    import json

    mongo = PyMongo(app)


    @app.route("/")
    def home_page():
        unsafe_search = request.args['search']
        json_search = json.loads(unsafe_search)
        safe_search = sanitize(unsanitized_search)

        result = client.db.collection.find_one({'data': safe_search})

    ```

```javascript
const excel = require('./index.js');

// 读取数据
const { data } = excel.readExcel('./customers.xlsx');

// 删除空行
const step1 = excel.removeEmptyRows(data);

// 去重
const step2 = excel.removeDuplicates(step1, '手机号');

// 文本清理
const step3 = excel.cleanText(step2, ['姓名', '地址']);

// 格式标准化（脱敏）

  row => ({ ...row, level: '优秀' }),
  row => ({ ...row, level: '良好' })
);
```

#### 4. 脚本执行
```javascript
// 自定义计算
const result = excel.executeScript(data, (row, index) => ({
  ...row,
  年薪：row.月薪 * 12,
  奖金：row.月薪 * 0.1
}));
```

description: 飞书语音交互技能。支持语音消息自动识别、AI 处理、语音回复全流程。需要配置 FEISHU_APP_ID 和 FEISHU_APP_SECRET 环境变量。使用 faster-whisper 进行语音识别，Edge TTS 进行语音合成，自动转换 OPUS 格式并通过飞书发送。适用于飞书平台的语音对话场景。
---

# Li Feishu Audio - 飞书语音交互技能

## 快速开始

本技能提供完整的飞书语音交互能力：

```
用户语音 → faster-whisper 识别 → AI 处理 → Edge TTS 合成 → OPUS 转换 → 飞书发送
```

## 核心组件

### 1. 语音识别 (fast-whisper)

**脚本**: `scripts/fast-whisper-fast.sh`

**用法**:
```bash
./scripts/fast-whisper-fast.sh <音频文件.ogg>
```

**配置**:
- 模型：faster-whisper tiny
- 语言：中文 (zh)
- 模型目录：可配置（环境变量 `FAST_WHISPER_MODEL_DIR`）
- 虚拟环境：技能目录下的 `.venv`（自动创建）

### 2. 语音合成 (Edge TTS)

**脚本**: `scripts/tts-voice.sh`

**用法**:
```bash
./scripts/tts-voice.sh "文本内容" [输出文件.mp3]
```

**配置**:
- 音色：zh-CN-XiaoxiaoNeural (中文女声)
- 输出格式：MP3 (自动转换为 OPUS)
- 虚拟环境：技能目录下的 `.venv`（自动创建）

### 3. 飞书语音发送

**脚本**: `scripts/feishu-tts.sh`

**用法**:
```bash
./scripts/feishu-tts.sh <音频文件.mp3> [用户 ID]
```

**配置**:
- 飞书 AppID: 从环境变量或 openclaw.json 读取
- 音频格式：OPUS (48kHz, 自动转换)
- 消息类型：audio

### 4. 自动清理

**脚本**: `scripts/cleanup-tts.sh`

**用法**:
```bash
./scripts/cleanup-tts.sh [保留数量]
```

**定时任务**: 每天凌晨 2 点自动执行

## 完整工作流

### 接收用户语音消息

1. 飞书收到语音消息（OGG/OPUS 格式）
2. 保存到 OpenClaw 媒体目录（自动处理）
3. 调用 `fast-whisper-fast.sh` 识别

### 生成回复

1. 识别结果发送给大模型
2. 大模型生成文字回复
3. 调用 `tts-voice.sh` 生成语音

### 发送语音回复

1. TTS 生成 MP3 文件
2. `sendMediaFeishu` 自动转换为 OPUS
3. 通过飞书 API 发送语音消息

## 环境要求

### 系统依赖

```bash
# Python
Python 3.11+
uv 包管理器

# 音频处理
ffmpeg (支持 OPUS 编码)
jq (JSON 处理)

# 飞书 API
飞书开放平台应用凭证
```

### Python 环境

```bash
# 虚拟环境
技能目录/.venv （自动创建）

# 已安装包
faster-whisper==1.2.1
edge-tts==7.2.7
```

### 模型文件

```bash
# 语音识别模型
$FAST_WHISPER_MODEL_DIR/models--Systran--faster-whisper-tiny/
```

## 配置说明

### 飞书凭证

**方法 1: 环境变量**（推荐）

创建 `.env` 文件：
```bash
export FEISHU_APP_ID="cli_xxx"
export FEISHU_APP_SECRET="xxx"
```

**方法 2: openclaw.json**

```json
{
  "channels": {
    "feishu": {
      "enabled": true,
      "appId": "cli_xxx",
      "appSecret": "xxx"
    }
  }
}
```

**⚠️ 安全提示**：不要将凭证提交到版本控制系统！

### 自定义目录（可选）

在 `.env` 文件中配置：

```bash
# 模型目录（默认：$HOME/.fast-whisper-models）
export FAST_WHISPER_MODEL_DIR="/opt/fast-whisper-models"

# 虚拟环境目录（默认：技能目录/.venv）
export VENV_DIR="/path/to/venv"

# 临时文件目录（默认：/tmp）
export TEMP_DIR="/tmp"

# 日志目录（默认：技能目录/logs）
export LOG_DIR="/path/to/logs"

# OpenClaw 配置路径（默认：$HOME/.openclaw/openclaw.json）
export OPENCLAW_CONFIG="$HOME/.openclaw/openclaw.json"
```

### TTS 配置

```json
{
  "messages": {
    "tts": {
      "auto": "always",
      "provider": "edge",
      "edge": {
        "enabled": true,
        "voice": "zh-CN-XiaoxiaoNeural",
        "lang": "zh-CN"
      }
    }
  }
}
```

## 脚本说明

### fast-whisper-fast.sh

```bash
#!/bin/bash
# 语音识别脚本
export HF_ENDPOINT=https://hf-mirror.com  # 国内镜像
VENV_PYTHON="技能目录/.venv/bin/python"  # 由 install.sh 自动配置

# 用法
./fast-whisper-fast.sh <音频文件>
```

**输出格式**:
```
[0.00s -> 2.32s] 识别的文本内容
```

### tts-voice.sh

```bash
#!/bin/bash
# TTS 语音生成脚本
export HF_ENDPOINT=https://hf-mirror.com
VENV_PYTHON="技能目录/.venv/bin/python"

# 用法
./tts-voice.sh "文本内容" [输出文件.mp3]
```

### feishu-tts.sh

```bash
#!/bin/bash
# 飞书语音发送脚本
# 自动转换 MP3 → OPUS

# 用法
./feishu-tts.sh <音频文件.mp3> [用户 ID]
```

**转换参数**:
```bash
ffmpeg -y -i input.mp3 -acodec libopus -ar 48000 -ac 1 output.opus
```

### cleanup-tts.sh

```bash
#!/bin/bash
# TTS 临时文件清理脚本

# 用法
./cleanup-tts.sh [保留数量]  # 默认保留 10 个

# 定时任务（crontab）
0 2 * * * ./cleanup-tts.sh 10
```

## 故障排查

### 语音识别失败

**问题**: 无法识别语音内容

**检查**:
1. 模型是否下载：`ls $FAST_WHISPER_MODEL_DIR/`
2. 虚拟环境：`技能目录/.venv/bin/python --version`
3. 网络：`export HF_ENDPOINT=https://hf-mirror.com`

### TTS 生成失败

**问题**: 无法生成语音文件

**检查**:
1. edge-tts 安装：`uv pip list -p 技能目录/.venv | grep edge`
2. 网络连接：Edge TTS 需要访问微软服务
3. 输出目录权限

### 飞书发送失败

**问题**: 语音消息发送失败

**检查**:
1. 凭证配置：`echo $FEISHU_APP_ID`
2. 音频格式：必须是 OPUS
3. 用户 ID 类型：使用 open_id

## 性能指标

| 操作 | 耗时 |
|------|------|
| 语音识别 (tiny) | ~8-10 秒 |
| TTS 生成 | ~3-5 秒 |
| OPUS 转换 | <1 秒 |
| 飞书上传 | ~2-3 秒 |
| **总计** | **~15 秒** |

## 最佳实践

### 语音质量

1. **录音环境**: 安静环境，减少背景噪音
2. **说话速度**: 正常语速，避免过快
