# Exploit Title: Lenovo RapidBoot HDD Accelerator - Unquoted Service Path Privilege Escalation
# Date: 10/19/2016
# Exploit Author: Joey Lane
# Version: 1.00.0802
# Tested on: Windows 7 Professional
The Lenovo RapidBoot HDD Accelerator service is installed 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 1.00.0802, but other versions may be affected as well.
