Name of the Vulnerable Software and Affected Versions McAfee Endpoint Security (ENS) for Windows versions prior to 10.7.0 September 2020 Update

Description The issue allows physical local users to bypass the Windows lock screen by triggering certain detection events while the computer screen is locked and the McTray.exe is running with elevated privileges. This is a timing-dependent exploit that requires physical access to the machine.

Recommendations For versions prior to 10.7.0 September 2020 Update, update to the September 2020 Update or later to resolve the issue. As a temporary workaround, consider restricting access to the McTray.exe when the computer screen is locked to minimize the risk of exploitation.
