# 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
|
