Local privilege escalation through undisclosed ETW flaw
Published Feb 25, 2021 · Updated Nov 19, 2024
Elevation of privilege in Microsoft Windows Event Tracing allows local users with low privileges to gain elevated privileges. Microsoft has not published the affected ETW function, data structure, or incorrect operation on attacker-controlled input. Exploitation requires local low-privilege access; success permits control at a higher privilege level, while the public record does not identify the resulting account or execution context.
