CVE-2022-43843Network attack vector

Sensitive-data decryption via weak DAS TLS cryptography

Published Dec 14, 2023 · Updated Aug 3, 2024

Weak cryptography in IBM Spectrum Scale 5.1.5.0 through 5.1.5.1 allows remote attackers to decrypt sensitive DAS TLS traffic. The Data Access Services TLS connection uses weaker-than-expected cryptographic algorithms, but IBM does not identify the algorithm or configuration responsible. The attacker must obtain protected DAS traffic and defeat its negotiated protection; the reported consequence is disclosure, not modification or service interruption.
