CVE-2022-22355Network attack vector

Unauthenticated service degradation

Published Apr 5, 2022 · Updated Sep 17, 2024

Denial of service in IBM MQ Appliance 9.2 CD and 9.2 LTS allows remote attackers to degrade performance through its Login component. IBM has not published the request format, named code locus, or incorrect operation that causes resource degradation. No authentication or user interaction is required, and the documented consequence is reduced performance rather than a crash or shutdown.
