CVE-2024-35116Network attack vector

Unauthenticated service interruption during configuration changes

Published Jun 28, 2024 · Updated Aug 2, 2024

Denial of service in IBM MQ Server 9.0 LTS, 9.1 LTS, 9.2 LTS, 9.3 LTS, and 9.3 CD allows remote attackers to interrupt messaging. IBM identifies the affected locus only as the Server component and states that an error occurs while configuration changes are applied; it does not disclose the failing operation or input. No privileges or user interaction are required; IBM does not disclose the additional conditions needed for successful exploitation, and only service availability is affected.
