Security - Security Analysis

安全分析工具，扫描代码漏洞、检查依赖、提供修复建议。

Version: 1.1

Features: 漏洞扫描、依赖检查、密钥检测、安全建议、C/C++ 支持 (NEW)

Quick Start

1. 扫描代码

# 扫描单个文件
python3 scripts/main.py scan --file src/main.py

# 扫描整个项目
python3 scripts/main.py scan --dir src/

2. 检查依赖

# 检查依赖漏洞
python3 scripts/main.py deps --requirements requirements.txt

# 检查 package.json
python3 scripts/main.py deps --package-json package.json

3. 检测密钥泄露

# 扫描密钥泄露
python3 scripts/main.py secrets --dir .

Commands

安全扫描

$ python3 scripts/main.py scan --file src/auth.py

🔒 Security Scan Results
=========================

File: src/auth.py
Issues found: 2

🔴 Critical:
  Line 34: Hardcoded password
    password = "admin123"  # ← Move to environment variable
  
  CWE-798: Use of Hard-coded Credentials

🟡 Medium:
  Line 67: SQL injection risk
    cursor.execute(f"SELECT * FROM users WHERE id = {user_id}")
  
  CWE-89: SQL Injection
  Fix: Use parameterized queries

✅ No secrets detected

依赖检查

$ python3 scripts/main.py deps --requirements requirements.txt

📦 Dependency Check
===================

Checked: 15 packages
Issues: 2

🔴 CVE-2023-1234: requests < 2.31.0
   Severity: High
   Fix: pip install requests>=2.31.0

🟡 CVE-2023-5678: flask < 2.3.0
   Severity: Medium
   Fix: pip install flask>=2.3.0

✅ All other dependencies up to date

密钥检测

$ python3 scripts/main.py secrets --dir .

🔑 Secret Detection
===================

Scanned: 45 files
Secrets found: 1

🔴 .env (line 3):
   AWS_SECRET_ACCESS_KEY = "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
   
   Type: AWS Secret Access Key
   Action: Move to secrets manager or environment variable

⚠️  Remember to rotate exposed credentials!
