Privilege escalation via failed initialization continuation
Published Jul 12, 2021 · Updated Sep 17, 2024
Privilege escalation in Dell Technologies Unity before 5.1.0.0.5.394 allows local users with Service access to gain elevated privileges. The proprietary initialization path continues executing after initialization fails instead of exiting, but Dell has not identified the affected routine or failed operation. Exploitation requires an authenticated, highly privileged Service account and can alter data or interrupt service, while Dell reports no confidentiality impact.
