CVE-2023-28066

Local privilege escalation through undisclosed access-control flaw

Published Jun 1, 2023 · Updated Jan 8, 2025

Improper access control in Dell OS Recovery Tool 2.2.4013 and 2.3.7012.0 allows local users to elevate privileges on Windows. Dell identifies proprietary code as the affected component but has not published the specific access-control check or operation that mishandles untrusted input. Exploitation requires an authenticated non-administrator account and user interaction, and successful abuse compromises the host at elevated privilege.
