Summary
Authentication is not configured by default for the Node-RED server on the Pilz industrial PC IndustrialPI. An unauthenticated remote attacker has full access to the Node-RED server and can run arbitrary operating system commands on the underlying operating system with privileged rights.
Impact
The attacker can not only view but create and alter flows in Node-RED. Flows can contain code blocks where commands are executed on the IndustrialPI itself. An attacker can use these code blocks to run any command as a privileged user on the IndustrialPI.
