IBM WebSphere MQ queue manager privilege escalation

websphere-mq-privilege-escalation (48529) The risk level is classified as MediumMedium Risk

Description:

The WebSphere MQ queue manager could allow a local attacker to gain elevated MQ privileges on the system, caused by a vulnerability in the setmqaut, dmpmqaut, and dspmqaut authorization commands. This vulnerability can only be exploited with the ability to log in to a user account on the machine hosting the WebSphere MQ queue manager. This level of log in access is expected to be tightly controlled in a production environment.IBM3

Note: Only those versions of WebSphere MQ running on UNIX operating systems are vulnerable to this issue.
