    # Date: 10/19/2016

    # Version: 4.1.12
    # Tested on: Windows 7 Professional
     
    PDF Complete Corporate Edition installs a service with an unquoted service path.
    This 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.
     
     
    This was tested on version 4.1.12, but other versions may be affected as well.
