身分聯盟 (SAML / OIDC / OAuth)

用於對聯合身分系統(包括 SAML、OIDC、OAuth2 流程、SSO 配置錯誤和令牌混淆問題)進行授權評估。

OIDC / OAuth) 是什麼?

此技能專注於安全測試聯合身分系統,涵蓋 SAML、OIDC 和 OAuth2 等主流協議。它幫助安全專業人員識別常見的配置錯誤,例如 SAML Response 簽名驗證缺失、斷言篡改、OIDC 隱含流程中 PKCE 未實施、redirect_uri 驗證不嚴、state 與 nonce 綁定缺失,以及多租戶 issuer 混淆等問題。此技能支援的工具鏈包括 Burp Suite 搭配 SAML Raider 擴充、jwt_tool 以及瀏覽器 DevTools,並提供了清晰的工作流程,從協議流程映射、端點資訊收集,到逐一檢查簽名覆蓋範圍、演算法降級攻擊及會話固定等環節。它與 api-security 技能互補,後者側重純 API 環境下的 JWT 攻擊,而此技能則專注於 SSO 流程中的安全缺陷。適合在滲透測試或紅隊演練中,對整合了企業 IdP 或雲端 IdP 的系統進行深度身分安全評估。

OIDC / OAuth) 是做什麼的?

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

路由上下文

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

Individual skills in this repo

This repo contains 20 individual skills — each has its own dedicated page.

api-security

Use for authorized security assessment of REST, GraphQL, WebSocket, or SOAP APIs, including discovery, authentication, authorization, rate-limit, and CI/CD testing.

apk-reverse

在 CLI 环境下做 Android APK 逆向时使用。适用于 APK 解包、Java 反编译、smali 修改、重打包、Frida 动态 Hook,以及按需切换到 so/native 分析。优先使用本机已安装的 jadx、apktool、frida、adb、ida-reverse、radare2。

attack-chain

Use for authorized multi-stage attack-path planning and orchestration when a task spans reconnaissance, initial access, privilege escalation, lateral movement, or impact assessment. Route single-stage tasks directly to their specialist skill.

binary-ninja-reverse

Use for authorized binary analysis in Binary Ninja, including HLIL/MLIL/LLIL inspection, strings/imports/exports, cross-references, types, patch review, Python API automation, and optional Binary Ninja MCP or localhost HTTP integration.

browser-automation

|

browser-extension-reverse

Use for authorized reverse engineering of browser extensions (Chrome/Firefox) including manifest analysis, background workers, and extension-based credential or traffic logic recovery.

case-review

Reviews a reverse-skill case package for scope readiness, Evidence to Finding to Path traceability, work item coverage, timeline references, and optional artifact hash integrity before report handoff.

cloud-k8s

Use for authorized cloud, container, and Kubernetes security assessment including metadata SSRF, IAM misconfig, container escape paths, and cluster RBAC review.

code-audit

Use for authorized source-code security review and SAST workflows including Semgrep, CodeQL patterns, dangerous API hunting, and fix verification.

ctf-sandbox

Thin PRIMARY for CTF / AWD / 靶场 multi-type orchestration. Hands off to the sidecar CTF-Sandbox-Orchestrator. Use when the user says CTF, AWD, 靶场, or 比赛题 and no more specific pwn/APK/IDA route already won.

database-security

Use for authorized database security assessment covering PostgreSQL/MySQL/MSSQL/Mongo/Redis exposure, authz, UDF/command paths, and misconfiguration review.

diagram-generator

generate, refine, validate, and render diagrams from natural language, notes, code snippets, schemas, tables, or existing diagram source. use for flowcharts, swimlanes, sequence diagrams, state diagrams, er diagrams, class diagrams, architecture/c4-style diagrams, dependency graphs, gantt charts, mind maps, user journeys, sankey-style flows, org charts, network graphs, and other visual models. supports mermaid by default, graphviz dot for complex graph layout, plantuml for uml-heavy engineering diagrams, and svg output when direct markup is more reliable.

digital-forensics

Use for authorized digital forensics including memory dumps, disk timelines, PCAP investigation, artifact triage, and IR evidence preservation.

docs-generator

|

dotnet-reverse

.NET / C# 二进制逆向。当目标是 .NET assembly(PE 头含 CLR、.exe/.dll 托管程序)、C# 编译产物(含 NativeAOT)、红队 Sharp* 工具(Rubeus / SharpHound / SharpHound 等)、.NET 混淆程序(ConfuserEx / SmartAssembly / Babel / Eazfuscator)、.NET loader / info-stealer / 套壳 malware 时使用。优先用 dnSpyEx + de4dot,需要 AI 直接操作时联动 dnSpy MCP。不用于纯 native 二进制(走 reverse-engineering / ida-reverse)。
