CVE-2022-34320Network attack vector

Sensitive-data decryption via weak cryptographic algorithms

Published Nov 14, 2022 · Updated Apr 29, 2025

Weak cryptography in IBM CICS TX 11.1 allows remote attackers to decrypt highly sensitive information over a network. IBM identifies weaker-than-expected cryptographic algorithms but does not disclose the affected component, algorithm, key handling, or cryptographic operation. Exploitation requires no privileges or user interaction but has high attack complexity, and the reported consequence is confidentiality loss only.
