CVE-2026-41655 Details
Description
Admidio is an open-source user management solution. Prior to version 5.0.9, the ecard_preview.php endpoint does not validate that the ecard_template POST parameter is a safe filename before passing it to ECard::getEcardTemplate(). An authenticated user can supply a path traversal payload (e.g., ../config.php) to read arbitrary files accessible to the web server process, including adm_my_files/config.php which contains database credentials. This issue has been patched in version 5.0.9.
A path traversal vulnerability has been identified in Admidio versions prior to 5.0.9, specifically within the ecard_preview.php endpoint. The issue arises because the endpoint fails to properly validate the ecard_template POST parameter, allowing authenticated users to manipulate the parameter and access arbitrary files on the server. This includes accessing the adm_my_files/config.php file, which contains sensitive database credentials. The vulnerability exists because the parameter is only sanitized to remove HTML tags, without restricting path traversal characters. In contrast, a similar endpoint (ecard_send.php) includes proper validation, highlighting a significant oversight in the preview endpoint.
Users are advised to update to Admidio version 5.0.9, where this vulnerability has been patched.
