Summary

YMS-VPN8 and YMS-VPN8-CP by Yamaha register Windows services with unquoted file paths. A user with write permissions on the system drive may be able to execute arbitrary code with SYSTEM privileges.

Risk Assessment

A user able to write to the system drive could escalate privileges to SYSTEM and take over the host. This poses a serious privilege escalation risk on workstations and servers running the Yamaha software.

Recommendation

Update YMS-VPN8/YMS-VPN8-CP to the vendor-fixed version and restrict write permissions on the system drive to the minimum necessary.
