# 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.

EXAMPLE:
  
Using the BINARY_PATH_NAME listed above as an example, an executable named
"Program.exe" could be placed in "C:\", and it would be executed as the
Local System user next time the service was restarted.
