Intel(R) Management Engine Components – Unquoted Service Path Privilege Escalation

The Intel(R) Management and Security Application Local Management Service (LMS) is installed with an unquoted service path, which enables a local privilege escalation vulnerability. To exploit this vulnerability, a local attacker can insert an executable file in the path of the service. Rebooting the system or restarting the service will run the malicious executable with elevated privileges.

Mitigation:

Ensure that all service paths are properly quoted and that only authorized executables are allowed to run.

"Program.exe" could be placed in "C:\", and it would be executed as the
Local System user next time the service was restarted.
