The vulnerability is caused due to an error in application when uploading thumbnails, which allows uploading of files with arbitrary extensions to a folder inside the webroot. This can be exploited to e.g. execute arbitrary PHP code by uploading a PHP file. NOTE: The stored file name is based on the original file name and a time stamp, which is predictable. The vulnerability is confirmed in version 3.53.5J on Joomla!. Other versions may also be affected. SOLUTION: Restrict access to the "components/com_remository_files" directory (e.g. via .htaccess).
