Who's got the magic stick? It sure as hell ain't 50 Cent.******
Excuse me for posting again (within minutes) but I did not properly check the other forms.
In UCP.php, when editing your profile, in several fields you can inject code into the page, just as in the SendPm.php.
EX: Input table: "URL" '';!--"<script>alert(String.fromCharCode(88,83,83)); </script>
The reason we cannot just do alert("sometext"); here is because this time our input is filtered and the quotes have \'s before them (single or not).
All field areas (besides password) are useable. I could not try alias as the board would not allow me to do so. Even the email field is vulnerable, so long as you put an email first (like firstname.lastname@example.org'';!--"<mycode>).
In "User Options", signature or 'saying' are not vulnerable, but URL Avatar is.
