Local privilege escalation
Published Jan 12, 2021 · Updated Oct 8, 2024
Elevation of privilege in Windows Event Tracing in affected Windows 10 and Windows Server releases allows local users to gain elevated privileges. Microsoft has not published the affected Event Tracing locus or the operation that mishandles attacker-controlled input. Exploitation requires existing low-privileged local access and can grant control over protected data, system changes, and service operation.
