Title: SOUND4 Server Service 4.1.102 Local Privilege Escalation
Advisory ID: ZSL-2022-5721
Type: Local
Impact: Privilege Escalation
Risk: (2/5)
Release Date: 14.12.2022
Summary
SOUND4 Windows Server Service.
Description
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.
