How it fires

How this skill gets triggered: by you, by Claude, or both.

  • Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

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_tool | JWT 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?
