Description

The version of IBM WebSphere MQ server 7.1 installed on the remote Windows host is missing fix pack 7.1.0.1 or later. It is, therefore, affected by a vulnerability where client applications can bypass the security configuration setup on an MQ SVRCONN channel, allowing unauthorized users access to the queue manager.
