CVE-2022-38391

Sensitive-data decryption via weak cryptographic algorithms

Published Dec 20, 2022 · Updated Apr 15, 2025

Weak cryptography in IBM Spectrum Control 5.4 allows local users to decrypt highly sensitive information from protected data. IBM has not published the affected component, algorithm, key material, or the operation that applies the weak cryptography. Local access and high attack complexity are required; the reported consequence is disclosure, with no integrity or availability impact.
