# Exploit Title: Intel(R) PROSet/Wireless WiFi Software - Unquoted Service Path Privilege Escalation
# Date: 10/19/2016
# Exploit Author: Joey Lane
# Version: 15.01.1000.0927
# Tested on: Windows 7 Professional
The Intel(R) PROSet/Wireless WiFi Software installs 2 services with unquoted service paths.
This enables a local privilege escalation vulnerability.
To exploit this vulnerability, a local attacker can insert an executable file in the path of either service.
Rebooting the system or restarting either service will run the malicious executable with elevated privileges.
This was tested on version 15.01.1000.0927, but other versions may be affected as well.
