CVE-2024-25016Network attack vector

Unauthenticated service interruption via incorrect buffering logic

Published Mar 3, 2024 · Updated Aug 1, 2024

Denial of service in IBM MQ 9.0, 9.1, 9.2, and 9.3 allows remote attackers to interrupt messaging via unauthenticated network input. IBM identifies incorrect buffering logic in the Runtime, Server, and Standard Client components but has not disclosed the affected code path or the buffer operation performed on untrusted data. No authentication or user interaction is required, and successful exploitation can make affected messaging components unavailable without reported data disclosure or modification.
