# Identity Federation (SAML / OIDC / OAuth)

## 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

```text
□ 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 |
