Unauthenticated information disclosure via risky authentication cryptography
Published Oct 7, 2025 · Updated Oct 7, 2025
Broken cryptography in Dell PowerProtect Data Domain DD OS 7.7.1.0 through 8.3.1.0 allows remote attackers to disclose information. The authentication component uses a broken or risky cryptographic algorithm, but Dell has not disclosed the algorithm, protected value, or affected request path. No authentication or user interaction is required, and Dell bounds the impact to information disclosure, with no reported data 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=7.10.1.0 <7.10.1.70
- Affected versionversion=7.13.1.0 <7.13.1.40
- Affected versionversion=7.7.1.0 <8.4.0.0
- Affected versionversion=8.3.1.0 <8.3.1.10
