Здравствуйте, не могли бы вы подсказать ?

выдает на страничке:

Warning: include_once(../config.php) [function.include-once]: failed to open stream: No such file or directory in /www/ontariow/www/htdocs/usercp/store/addbal.php on line 1

Warning: include_once() [function.include]: Failed opening '../config.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /www/ontariow/www/htdocs/usercp/store/addbal.php on line 1

Это несет в себе уязвимость ?
