Burp插件开发实战：越权检测插件开发指南<\/h1>

一、前言<\/h2>
本教程将详细介绍如何开发一个Burp Suite越权检测插件，该插件能够自动检测水平越权、垂直越权和未授权访问漏洞。通过本教程，您将学习到Burp插件开发的核心技术，包括监听器使用、HTTP请求解析、对象工厂和GUI开发等知识。<\/p>

二、越权检测原理<\/h2>

1. 越权类型<\/h3>

水平越权<\/strong>：同级别用户访问彼此资源<\/li>
垂直越权<\/strong>：低权限用户访问高权限功能<\/li>

未授权访问<\/strong>：无需认证即可访问受限资源<\/li> <\/ul>
2. 检测方法<\/h3>
主流检测方案是通过替换token观察响应是否与原始响应一致。但存在以下问题：<\/p>

系统中存在大量公共页面，导致误报率高<\/li>
完全自动化检测不可行，通常采用半自动化方式<\/li> <\/ul>
3. 高风险接口特征<\/h3>

具有资源ID且资源ID可遍历<\/li>
返回包包含敏感信息<\/li> <\/ul>
三、插件功能设计<\/h2>
1. 核心功能<\/h3>

根据设置的资源ID和敏感信息自动筛选待检测URL<\/li>
收集配置域名的所有参数并一键添加到配置中<\/li> <\/ol>
2. GUI设计<\/h3>
采用三标签页设计：<\/p>

URL展示页<\/strong>：显示检测结果<\/li>
配置页<\/strong>：设置检测参数<\/li>
参数列表页<\/strong>：管理收集的参数<\/li> <\/ul>
四、代码实现详解<\/h2>
