// WARNING: don't just set "$Config['Enabled'] = true ;", you must be sure that only
//      authenticated users can access this file or use some kind of session checking.
$Config['Enabled'] = true ; // <= 1
 
---
 
// Path to user files relative to the document root.
$Config['UserFilesPath'] = '/userfiles/' ;  // <= here is the path of attacker file or shell backdoor will be placed.
 
// following setting enabled.
$Config['ForceSingleExtension'] = true ;    // <= 2
 
$Config['AllowedExtensions']['File']    = array('7z', 'aiff', 'asf', 'avi', 'bmp', 'csv', 'doc', 'fla', 'flv', 'gif', 
'gz', 'gzip', 'jpeg', 'jpg', 'mid', 'mov', 'mp3', 'mp4', 'mpc', 'mpeg', 'mpg', 'ods', 'odt', 'pdf', 'png', 'ppt', 
'pxd', 'qt', 'ram', 'rar', 'rm', 'rmi', 'rmvb', 'rtf', 'sdc', 'sitd', 'swf', 'sxc', 'sxw', 'tar', 'tgz', 'tif', 'tiff',
