User-content disclosure via forgeable SHA-1 code signatures
Published Sep 19, 2022 · Updated Aug 3, 2024
Use of a weak hash in Western Digital WD Discovery before 4.4.396 allows remote attackers to expose user content via forged signatures. The application's executable files carry SHA-1 code-signing signatures, whose collision weakness permits a forged certificate signature to be accepted as trusted. Exploitation requires interaction with attacker-controlled signed content, and the documented consequence is limited to disclosure of user content.

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.
