Vulnerability Title
Admidio: Path Traversal via Unvalidated `name` Parameter in Document Add Mode Enables Arbitrary Server File Read
Source: NVD (National Vulnerability Database)
Vulnerability Description
Admidio is an open-source user management solution. Prior to version 5.0.9, the add mode in modules/documents-files.php accepts a name parameter validated only as 'string' type (HTML encoding), allowing path traversal characters (../) to pass through unfiltered. Combined with the absence of CSRF protection on this endpoint and SameSite=Lax session cookies, a low-privileged attacker can trick a documents administrator into clicking a crafted link that registers an arbitrary server file (e.g., install/config.php containing database credentials) into a documents folder accessible to the attacker. This issue has been patched in version 5.0.9.

Admidio 路径遍历漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Admidio是Admidio团队的一套开源的成员管理系统。该系统支持成员列表、事件管理、留言簿、相册和下载等功能。 Admidio 5.0.9之前版本存在路径遍历漏洞，该漏洞源于modules/documents-files.php的添加模式仅验证name参数为字符串类型，允许路径遍历字符通过，且端点缺乏CSRF保护，可能导致低权限攻击者诱骗文档管理员注册任意服务器文件。
