RSLinx Classic is a software platform that allows Logix5000 Programmable Automation Controllers to connect to a wide variety of Rockwell Software applications, and FactoryTalk Linx Gateway is a software that provides an Open Platform Communications (OPC) Unified Architecture (UA) server interface to allow the delivery of information from Rockwell Software applications to Allen-Bradley controllers.
The application suffers from an unquoted search path issue impacting the service 'dnwhodisp' for Windows deployed as part of RSLinx and FactoryTalk. 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.
