Unauthenticated information disclosure and tampering
Published Jun 17, 2026 · Updated Jun 17, 2026
Broken cryptography in Dell PowerFlex Manager before 5.1.0.1 allows remote attackers to read and tamper with information. Dell has not published the cryptographic algorithm, protocol, key-handling path, or request field that performs the unsafe operation. Exploitation requires no authentication or user interaction but has high complexity, and the reported consequence is limited to information disclosure and modification.

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=0 <4.5.5.2 or later
- Affected versionversion=0 <5.1.0.1 or later
