Privilege Escalation Web

DevOps & Security
privilege-escalation-web

Privilege Escalation Web is an Agent Skill for devops & security published in the wgpsec/AboutSecurity repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Web 应用层权限提升。当 Web 应用存在用户注册/登录、角色权限管理、API 参数传输用户身份信息时使用。覆盖 Mass Assignment（批量赋值）攻击、角色/权限字段注入、HTTP 方法/Header 绕过、Cookie/Session 篡改。注册后立即检查普通用户能否越权访问管理员功能——这是第一优先级

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

  1. Open your project in Codex.
  2. Copy and paste the prompt below.
  3. Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/wgpsec/AboutSecurity/blob/HEAD/skills/exploit/web-method/privilege-escalation-web/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/privilege-escalation-web, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

Web 权限提升方法论

Web 权限提升和系统提权不同——不需要 exploit，只需要找到应用逻辑中的权限检查漏洞。

⛔ 深入参考（必读）

Phase 1: 认证和账户发现

默认凭据（最快路径）

admin:admin, admin:password, admin:123456
root:root, root:toor, test:test, guest:guest

注册功能分析

注册新账户，用代理拦截请求，记录请求格式、发送字段、响应字段（可能暴露隐藏字段名）。 检查 /docs, /swagger, /openapi.json。

Phase 2: Mass Assignment（核心技术）

在注册或更新请求中添加应用未预期的字段（每次只加一个）：

{"username":"test", "password":"pass", "role":"admin"}
{"username":"test", "password":"pass", "is_admin":true}
{"username":"test", "password":"pass", "is_staff":1}

→ 完整字段清单和框架惯例 → references/web-privesc-techniques.md

Phase 3: 管理端点直接访问

GET /admin → 403? → 试 /admin/ (trailing slash) 或 /Admin (大小写)
GET /api/admin/users → 200?

Phase 4: HTTP 方法/Header 篡改 + Cookie 篡改

GET /admin/flag → 403 → 试 POST/PUT/PATCH
Header: X-Original-URL: /admin/flag / X-Forwarded-For: 127.0.0.1
Cookie: role=user → role=admin / admin=0 → admin=1

→ 完整 payload 和 Flask session 伪造 → references/web-privesc-techniques.md

Phase 5: 对象级越权

修改 URL/参数中的 ID 访问他人资源

注意事项

  • Mass Assignment 每次只改一个字段——全改可能触发 WAF
  • 注册后检查 GET /api/users/me 确认权限是否真的变了
  • 结合 IDOR + Mass Assignment 效果更好
