CVE-2024-27255Network attack vector

Sensitive-data decryption via weak cryptography

Published Mar 3, 2024 · Updated Aug 2, 2024

Weak cryptography in IBM MQ Operator 2.0.0 LTS through 2.0.18 LTS and other affected releases allows remote attackers to decrypt sensitive data. IBM has not published the algorithm, protocol, key-management locus, or incorrect cryptographic operation that exposes the data. Other affected branches are 2.2.0 through 2.2.2, 2.3.0 through 2.3.3, 2.4.0 through 2.4.7, and 3.0.0 CD through 3.0.1 CD; exploitation requires no privileges or user interaction, has high complexity, and is limited to disclosure.
