10 阶段测试流程

10-Phase Testing Process

Phase 1: API 发现与侦察

Phase 1: API Discovery and Reconnaissance

text
主动发现：
□ Vespasian: 无头浏览器爬取 → 自动生成 OpenAPI 3.0 / GraphQL SDL 规范
□ Entropy --discover: 从 robots.txt + JS 文件提取端点
□ Kiterunner / ffuf: 爆破未文档化的端点路径
□ 检查常见路径: /swagger.json, /openapi.json, /graphql, /api-docs

GraphQL 内省（三级尝试）：
  1. 标准内省查询
  2. 精简查询（绕过 WAF 全量封禁）
  3. 仅查 __schema { types { name } }（最小探测）
text
Active Discovery:
□ Vespasian: Headless browser crawling → Automatically generate OpenAPI 3.0 / GraphQL SDL specifications
□ Entropy --discover: Extract endpoints from robots.txt + JS files
□ Kiterunner / ffuf: Bruteforce undocumented endpoint paths
□ Check common paths: /swagger.json, /openapi.json, /graphql, /api-docs

GraphQL Introspection (Three-level Attempt):
  1. Standard introspection query
  2. Simplified query (bypass WAF full-block)
  3. Only query __schema { types { name } } (minimal detection)

Phase 2: 认证测试

Phase 2: Authentication Testing

text
JWT 分析（jwt_tool / Burp）：
□ alg:none 攻击: 修改头部为 "alg":"none"，清空签名
□ 密钥混淆: RS256 公钥 → HS256 对称密钥
□ 弱 HMAC 密钥爆破: jwt_tool -C -d wordlist.txt
□ 过期/声明篡改: 修改 exp/iat/sub/role 声明
□ kid 注入: ../../etc/passwd → HMAC 签名绕过

OAuth 2.0：
□ redirect_uri 操控 → 授权码泄漏
□ CSRF via state 参数缺失
□ Token 在 Referer 头泄漏
□ PKCE 缺失检测

GraphQL 认证：
□ mutation 通过 GET 请求绕过认证（CSRF）
□ 批查询认证绕过
text
JWT Analysis (jwt_tool / Burp):
□ alg:none attack: Modify header to "alg":"none", clear signature
□ Key confusion: RS256 public key → HS256 symmetric key
□ Weak HMAC key brute-force: jwt_tool -C -d wordlist.txt
□ Expiration/claim tampering: Modify exp/iat/sub/role claims
□ kid injection: ../../etc/passwd → HMAC signature bypass

OAuth 2.0:
□ redirect_uri manipulation → Authorization code leakage
□ CSRF via missing state parameter
□ Token leakage in Referer header
□ PKCE absence detection

GraphQL Authentication:
□ mutation bypasses authentication via GET request (CSRF)
□ Batch query authentication bypass

Phase 3: 授权测试（BOLA/IDOR/BFLA）

Phase 3: Authorization Testing (BOLA/IDOR/BFLA)

text
BOLA（对象级授权绕过）：
□ 遍历数字 ID: /user/1 → /user/2 → /user/3
□ 遍历 UUID
□ 遍历用户名/邮箱
□ Burp Autorize: 双会话重放对比

BFLA（功能级授权绕过）：
□ 普通用户执行管理员 API
□ HTTP 方法切换: GET → PUT → PATCH → DELETE
□ API 版本降级: /v2/admin → /v1/admin
□ 批量操作注入: {"users": [1,2,3]} → {"users": [1,2,3,admin_id]}

工具: Burp Autorize, AuthMatrix, Entropy (malicious_insider persona)
text
BOLA (Object-level Authorization Bypass):
□ Numeric ID traversal: /user/1 → /user/2 → /user/3
□ UUID traversal
□ Username/email traversal
□ Burp Autorize: Dual-session replay comparison

BFLA (Function-level Authorization Bypass):
□ Regular user executes admin API
□ HTTP method switching: GET → PUT → PATCH → DELETE
□ API version downgrade: /v2/admin → /v1/admin
□ Batch operation injection: {"users": [1,2,3]} → {"users": [1,2,3,admin_id]}

Tools: Burp Autorize, AuthMatrix, Entropy (malicious_insider persona)
