CVE-2022-43917Network attack vector

Sensitive-data decryption via weak cryptographic keys

Published Jan 25, 2023 · Updated Mar 31, 2025

Weak cryptographic keys in IBM WebSphere Application Server traditional container 8.5 and 9.0 allow remote attackers to decrypt sensitive data. The container image provisions weaker-than-expected cryptographic keys, but IBM has not disclosed the key-generation locus, algorithm, or affected ciphertext. Only traditional container images are affected; network access requires no authentication, but exploitation has high complexity and affects confidentiality only.
