Sensitive-data decryption via weak DAS TLS cryptography
Published Dec 14, 2023 · Updated Aug 3, 2024
Weak cryptography in IBM Spectrum Scale 5.1.5.0 through 5.1.5.1 allows remote attackers to decrypt sensitive DAS TLS traffic. The Data Access Services TLS connection uses weaker-than-expected cryptographic algorithms, but IBM does not identify the algorithm or configuration responsible. The attacker must obtain protected DAS traffic and defeat its negotiated protection; the reported consequence is disclosure, not modification or service interruption.

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=5.1.5.0 <=5.1.5.1
