ATK Hotkey 188.8.131.52 suffers from an unquoted search path issue impacting the service 'AsHidService'. This could potentially allow an
authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. 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.
Local, Non-privileged Local User with restart capabilities
