The Simple File Upload Module for Joomla! contains a flaw that allows a remote user to execute arbitrary PHP code. This flaw exists because the modules/mod_simplefileuploadv1.3/helper.php script does not properly verify or sanitize user-uploaded files. By uploading a .php file, the remote system will place the file in a user-accessible path. Making a direct request to the uploaded file will allow the user to execute the script.
