CVE-2024-40681Network attack vector

Authenticated queue-manager action execution via role bypass

Published Sep 7, 2024 · Updated Oct 31, 2024

Authorization bypass in the IBM MQ 9.1 LTS, 9.2 LTS, 9.3 LTS and CD, and 9.4 LTS and CD Console allows remote authenticated users to execute actions. IBM identifies the REST API and Console as affected but has not disclosed the authorization check that misassigns privileges. Exploitation requires network access and credentials for the affected role; IBM has not identified which queue-manager actions become available.
