Sensitive-information decryption via weak cryptographic algorithms
Published Dec 9, 2021 · Updated Sep 16, 2024
Weak cryptography in IBM Db2 9.7, 10.1, 10.5, 11.1, and 11.5 clients allows remote attackers to decrypt sensitive information. IBM has not disclosed the affected algorithm, the component that uses it, or the operation that makes protected data recoverable. Exploitation is unauthenticated over a network but requires high complexity; the reported consequence is confidentiality loss only.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=10.1
- Affected versionversion=10.5
- Affected versionversion=11.1
- Affected versionversion=11.5
