Sensitive-information decryption via weak cryptography
Published Apr 12, 2021 · Updated Sep 16, 2024
Weak cryptography in affected IBM Jazz Team Server-based Engineering products allows remote attackers to decrypt sensitive information. IBM identifies the Jazz Foundation cryptographic implementation as the locus but has not published the algorithm, key handling, or cryptographic operation that is weaker than expected. Exploitation requires network access and high-complexity conditions without authentication or user interaction; the documented impact 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=6.0.2
- Affected versionversion=6.0.6
- Affected versionversion=6.0.6.1
- Affected versionversion=7.0
- Affected versionversion=7.0.1
