CVE-2024-39742Network attack vector

Authentication bypass via partial string comparison

Published Jul 8, 2024 · Updated Aug 2, 2024

Authentication bypass in affected IBM MQ Operator releases allows remote attackers to reach protected functions without valid credentials. The Developer edition authentication path performs only a partial string comparison, but IBM does not disclose the compared value, function, or request field. The flaw is reachable without prior privileges only under certain configurations; IBM has not specified that configuration gate or the exact post-bypass actions.
