CVE-2024-28780Network attack vector

Sensitive-data decryption via undisclosed weak cryptography

Published Feb 19, 2025 · Updated Jul 25, 2025

Weak cryptography in IBM Cognos Controller 11.0.0 through 11.0.1 FP3 and IBM Controller 11.1.0 allows remote attackers to decrypt sensitive data. IBM has not disclosed the affected algorithm, cryptographic operation, key handling, or code locus, so the precise failure mechanism is not public. Exploitation requires network access and high-complexity conditions; the reported consequence is disclosure without data modification or service interruption.
