Identity Federation (SAML / OIDC / OAuth)

ACTION REQUIRED(读完后立刻执行)

  1. NOW: 读取 precedent-pentest;SSO 测试账号与 IdP/SP 范围入 scope
  2. NOW: 禁止锁定真实用户账户的暴力尝试
  3. NEXT: 抓包工具与文档(元数据 URL)
  4. ACT: 协议流映射 → 常见错配 → 验证

适用场景

  • SAML Response 签名/断言篡改面(经典缺陷模式)
  • OIDC 隐式/授权码 + PKCE 缺失
  • redirect_uri / state / nonce 问题
  • IdP 与 SP 元数据、多租户 issuer 混淆
  • 与 api-security JWT 攻击互补(本 skill 偏联邦与 SSO 流)

工作流

□ 画清:User → SP → IdP → Token → SP
□ 收集:/.well-known/openid-configuration、SAML metadata
□ 检查:redirect_uri 精确匹配、state 绑定、PKCE
□ 检查:SAML 签名覆盖范围、algorithm 降级
□ 会话固定与登出失效

工具链

工具用途
Burp + SAML Raider 等断言编辑(授权)
jwt_toolJWT 段
浏览器 DevTools重定向链
IdP 管理日志审计

参考

  • references/sso-flow-checklist.md
  • ../api-security/ ../windows-ad/(企业 IdP)

路由上下文

上游: MASTER R37
下游: 纯 API JWT → api-security;云 IdP → cloud-k8s

任务完成自检

  • 是否映射完整 SSO 流?
  • 每个 Finding 是否有复现与影响?
  • Checklist?
