# Ruby on Rails vulnerable to code injection
## 本地实证状态
- 实证状态: `triage-manual`
- 实证方式: `synthetic`
- Artifact 模式: `synthetic`
- 最近运行: `-`
- 浏览器证据: `missing`
- Run Bundle: `-`
## 事件层
- Canonical ID: `rails--CVE-2006-4111`
- 系统: `rails`
- 严重度: `high`
- 来源置信度: `official`
- 官方主源: https://nvd.nist.gov/vuln/detail/CVE-2006-4111
- 影响版本: `1.1.0, 1.1.1, 1.1.2, 1.1.3, 1.1.4, 1.1.5, introduced=1.1.0, fixed<1.1.6`
- 修复版本: `1.1.6`
## 对象与版本映射
- Advisory Scope: `package`
- 影响对象: `rails`
- Entity Refs: `rails, rails--project--rails`
- 版本置信度: `high`
- 版本缺口: `-`
- 版本证据源: `https://nvd.nist.gov/vuln/detail/CVE-2006-4111, http://blog.koehntopp.de/archives/1367-Ruby-On-Rails-Mandatory-Mystery-Patch.html, https://github.com/presidentbeef/rails-security-history/blob/master/vulnerabilities.md, https://github.com/rails/rails, https://github.com/rubysec/ruby-advisory-db/blob/master/gems/rails/CVE-2006-4111.yml`
## 受控验证流程
- Workflow ID: `rails--CVE-2006-4111--workflow`
- 漏洞家族: `xss`
- 入口面: `web-ui-render-path`
- 需要角色: `editor-or-admin`
- 触发向量: 对 `xss` 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: `/admin/editor, /preview, /rendered-content`
- 输入形态: 受控 HTML/Markdown/富文本输入，观察渲染上下文是否失去编码或净化。
- 预期不安全行为: 输入在目标上下文执行或被浏览器解释为主动内容。

## 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
### 补丁验证步骤
- 确认目标版本从 `1.1.0, 1.1.1, 1.1.2` 升级或回移到 `1.1.6`。
- 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 `xss` 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
