Local privilege escalation via unquoted executable paths

Unquoted search paths in HIMA HOPCS, X-OPC DA, X-OPC A+E, and X-OTS allow local users to execute code with administrator privileges. Windows resolves each unquoted executable path containing spaces through unintended candidate locations, so a malicious .exe placed earlier in the search order runs instead of the intended HIMA binary. A normal local account able to plant that file and trigger the component gains administrator-level control, while HIMA states that OPC access alone cannot change the safety-controller project.
