## 受控验证流程

- Workflow ID: `vite--CVE-2024-31207--workflow`
- 漏洞家族: `proxy-boundary`
- 入口面: `proxy-header-or-trust-boundary`
- 需要角色: `reverse-proxy-or-edge-client`
- 触发向量: 对 `proxy-boundary` 家族入口投递最小化、可审计、可回滚的受控输入，比较修复前后差异。
- 请求/页面入口: `/middleware, /x-forwarded-* trust path`
- 输入形态: 提交受控代理头或来源头，验证信任边界和回源鉴权。
- 预期不安全行为: 仅凭代理头即可越过鉴权或来源控制。

## 证据点与补丁验证

### 服务端证据点

- 应用日志中的命中路径、鉴权决策和异常栈
- 反向代理或边界层日志中的请求头、来源 IP 与路由决策

### 浏览器证据点

- 基线截图与攻击后截图的 DOM/视觉差异
- console、network 与 response metadata 中的异常信号

### 数据库/文件系统证据点

- 数据库中新增/越权读取的测试数据
- 文件系统中新增上传样本、缓存条目或越权读取痕迹

### 检测信号

- WAF / reverse proxy 异常日志、访问日志和告警
- 应用审计日志中的权限错误、重定向异常、模板渲染或上传落盘事件
- 上游代理与应用层对 Content-Length / Transfer-Encoding / forwarded headers 的解释差异

### 补丁验证步骤

- 确认目标版本从 `introduced=2.7.0, fixed<2.9.18, introduced=3.0.0, fixed<3.2.10, introduced=4.0.0, fixed<4.5.3` 升级或回移到 `2.9.18`。
- 保留同一组受控输入，在修复前后分别执行并比对响应、日志与浏览器证据。
- 确认修复后仅保留预期业务行为，不再触发越权、回显、异常渲染或错误请求。
- 补充 `proxy-boundary` 族自动化回归，避免同类路径在插件、主题或代理链中回归。

### 实验安全备注

- 只使用回环地址、哨兵目标、无害样本或可回滚测试数据。
- 禁止造成持久破坏、越权下载真实数据或不可回滚 side effect。
- 如需浏览器证据，保留 baseline / proof 两份快照以及 console / network 记录。

## 实验层

- 仅用于自有资产、测试环境或已明确授权目标。
- 允许公网可达目标，但必须满足资产归属或明确授权前提。
- 最小化验证方式: 最小化验证、只读探测、可审计回显、受控注入。
- 若该案例涉及插件、模块或扩展，应同时检查供应链与升级策略。
- 禁止场景: 无归属证明或无明确授权的公网目标；知名公共网站或与测试无关的第三方资产；会造成持久破坏、数据越权下载或不可回滚影响的动作
