// 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', 'txt', 'vsd', 'wav', 'wma', 'wmv', 'xls', 'xml', 'zip') ; // <= 3
