# 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.
