CVE-2021-39081Network attack vector

Sensitive-data decryption via weak cryptographic algorithms

Published Dec 19, 2024 · Updated Dec 19, 2024

Weak cryptography in IBM Cognos Analytics Mobile for Android 1.1.14 allows remote attackers to decrypt highly sensitive information. IBM identifies weaker-than-expected cryptographic algorithms but does not disclose the affected data path, cipher, key handling, or attack input. Network reachability requires no privileges or user interaction, but high attack complexity applies, and the reported consequence is limited to confidentiality.
