Local privilege escalation
Published Jan 12, 2021 · Updated Oct 8, 2024
Privilege escalation in Microsoft Windows 10 and Windows Server releases 2004 and 20H2 allows local users to gain elevated rights. Microsoft identifies the Windows Event Logging Service as the affected component but has not published the faulty operation or input path. A user must already hold low privileges on an affected host; successful exploitation compromises system confidentiality, integrity, and availability.
