• # Exploit Title: SOUND4 Server Service 4.1.102 - Local Privilege Escalation
  # Exploit Author: LiquidWorm
  
  Vendor: SOUND4 Ltd.
  Product web page: https://www.sound4.com | https://www.sound4.biz
  Affected version: 4.1.102
  
  Summary: SOUND4 Windows Server Service.
  
  Desc: The application suffers from an unquoted search path issue impacting
  the service 'SOUND4 Server' for Windows. 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.
  
  Tested on: Windows 10 Home 64 bit (build 9200)
   SOUND4 Server v4.1.102
   SOUND4 Remote Control v4.3.17
