CVE-2022-34310Network attack vector

Sensitive-data decryption via weak cryptographic algorithms

Published Feb 12, 2024 · Updated Apr 24, 2025

Weak cryptography in IBM CICS TX Standard and Advanced 11.1 allows remote attackers to decrypt highly sensitive information. IBM has not disclosed the affected algorithm, protocol, cryptographic operation, or code locus that uses weaker-than-expected cryptography. Exploitation is unauthenticated over a network but requires conditions that IBM rates as high complexity; the reported consequence is disclosure only.
