Summary

The RupsMon.exe service executable in UPSilon 2000 has insecure permissions, allowing the 'Everyone' group Full Control. A local attacker can replace the executable with a malicious binary to execute code with SYSTEM privileges or simply change the config path of the service to a command; starting and stopping the service to immediately achieve code execution and privilege escalation.

Risk Assessment

A local attacker could gain SYSTEM privileges, leading to full system compromise.

Recommendation

Restrict permissions on RupsMon.exe and service configuration so only administrators have full control, and update the software if a patch is available.
