QID 375345: IBM MQ Privilege Escalation Vulnerability (6409546)

IBM MQ is a message oriented middleware that allows independent and non-concurrent applications on a distributed system to communicate with each other.

Eclipse Jetty could allow a local authenticated attacker to gain elevated privileges on the system, caused by a race condition in the creation of the temporary subdirectory.

Affected Version:
IBM MQ Version 9.2.0

QID Detection Logic: (Authenticated)
Operating System: Linux
The QID runs the command "/opt/mqm/bin/dspmqver -v | grep -A3 '^Name'" and "/usr/mqm/bin/dspmqver -v | grep -A3 '^Name'" (for AIX only) to see if the system is running a vulnerable version of IBM MQ or not.
Operating System: Windows
It checks for vulnerable IBM MQ/WebSphere MQ versions.

By sending a specially-crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges.

  • CVSS V3 rated as High - 7 severity.
