1) Introduction
===============

Gallery 1.3.3 is an automated php Gallery engine. It is quite secure, and
very effective as a
web gallery.

2) Bug
======

When the webserver hosting gallery 1.3.3 recieves a "GET
/<galleryfolder>/search.php"
it reffers to search.php as it should. However when searching
"<script>alert('XSS')</script>"
or requests "GET
/<galleryfolder>/search.php?searchstring=<script>alert('XSS')</script>"
the server allows an attacker so inject & execute scripts.
