Name of the Vulnerable Software and Affected Versions Admidio versions prior to 4.0.4

Description The issue is related to an authenticated remote code execution (RCE) vulnerability via .phar file upload in Admidio. An attacker with upload permissions can rename a PHP web shell with a .phar extension and trigger the payload for a reverse/bind shell by visiting the file. This can be exploited through the Documents & Files upload feature. The vulnerability can be mitigated by excluding .phar file extensions from being uploaded.

Recommendations For versions prior to 4.0.4, update to version 4.0.4 to resolve the issue. As a temporary workaround, consider excluding .phar file extensions from being uploaded to prevent exploitation.
