CVE-2022-29839

Protected-data access via unencrypted backup credentials

Published Dec 9, 2022 · Updated Apr 22, 2025

Insufficiently protected credentials in Western Digital Cloud NAS firmware before 5.25.124 allow local users to access protected data. The Remote Backups application stores backup credentials without encryption at a relevant endpoint, allowing credential reuse against protected data. Exploitation requires high-privilege local access to that endpoint and does not alter data or interrupt the appliance.
