Summary
atvise scada is based on newest technologies and standards: The visualization in pure web technology as well as a consistent vertical object orientation based on OPC UA changes the world of process management systems.Description
The application suffers from an unquoted search path issue impacting the service 'atserver' for Windows deployed as part of atvise SCADA. 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.Vendor
