The application improperly validates uploaded files, which can be exploited to execute arbitrary PHP code by uploading a PHP file with e.g. an appended ".gif" file extension. Successful exploitation requires "Manager" permissions in the backend and that Apache is not configured to handle the mime-type for media files with e.g. a ".jpg" or ".gif" extension. The vulnerability is confirmed in version 1.8.1. Other versions may also be affected. SOLUTION: Restrict access to the jdownloads directory (e.g. via .htaccess).
