Unauthorized system access via weak credentials
Published Apr 17, 2026 · Updated Apr 17, 2026
Weak credentials in Dell PowerProtect Data Domain DD OS allow local users to gain unauthorized access to affected systems. Affected releases are Feature 7.7.1.0 through 8.5, LTS2025 8.3.1.0 through 8.3.1.20, and LTS2024 7.13.1.0 through 7.13.1.50; Dell has not disclosed which credential is weak or where it is checked. Physical or console-equivalent local access without prior authentication is required, and successful exploitation grants unauthorized system access.
