Vulnerability Details
CVE ID: CVE-2013-5401

Remediation/Fixes
REMEDIATION:
The recommended solution is to apply the fix for each named product as soon as
practical. Please see below for information on the fixes available.
FIX
WebSphere MQIPT 2.1.0.0
Apply fix pack 2.1.0.1
WebSphere MQIPT 2.0.x
Where possible, upgrade to WebSphere MQIPT 2.1.0.1, otherwise see workaround
below.
Workarounds and Mitigations
The CommandPort number is an optional property and this line can be removed
from the mqipt.conf file. If the CommandPort property is not present, MQIPT
does not listen for configuration commands. Please note that this workaround
(disabling the command port listener) means that the MQIPT administration
command (mqiptAdmin) will be unable to stop or refresh the MQIPT instance. It
will also stop the MQIPT GUI from being able to remotely administer the MQIPT
instance.
It is always recommended that MQIPT is operated inside a firewall, which is
set up to prevent access by untrusted users or systems.
