⚠️ AUTHORIZED USE ONLY

This skill is for educational purposes or authorized security assessments only.

You must have explicit, written permission from the system owner before using this tool.

Misuse of this tool is illegal and strictly prohibited.

Mandatory confirmation gate

Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

1. Ask the user to state the exact target URL, IP, account, or resource.

2. Ask the user to confirm written authorization and the permitted scope.

3. Show the exact command(s) and explain their expected effect.

4. Wait for explicit confirmation in the current conversation.

Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

Identity Federation (SAML / OIDC / OAuth)

When to Use

• Testing SSO/federation flows within an approved scope.
• Hunting signature-validation or audience-confusion flaws.

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
