Quick assessment

Affected
TYPO3 Extension "Modules"
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

该扩展未能对内联编辑的后端 AJAX 端点实施足够的访问控制，未限制仅允许当前用户查看或编辑的字段。经过身份验证的低权限后端用户可传入任意的表名、字段名和记录 ID 参数，触发错误响应，从而泄露所请求字段的当前数据库值，导致敏感信息（例如后端和前端用户的密码哈希）被泄露。利用该漏洞需要具备一个有效的、已认证的 TYPO3 后端用户账户，并拥有对该扩展后端模块的访问权限。

Vulnerability Title
Information Disclosure in extension "Modules" (modules)
Source: CVE Program / CVE List V5
Vulnerability Description
The extension fails to restrict a backend AJAX endpoint for inline editing to fields the current user is permitted to see or edit. An authenticated, low-privileged backend user can supply arbitrary table, field and record parameters, and trigger an error response that discloses the current database value of the requested field, leading to disclosure of sensitive information such as backend and frontend user password hashes. Exploitation requires a valid, authenticated TYPO3 backend user account with access to the extensions backend module.
