KUNBUS Revolution Pi Authentication Bypass by Primary Weakness
KUNBUS Revolution Pi OS Bookworm 01/2025 is vulnerable because authentication is not configured by default for the Node-RED server. This can give an unauthenticated remote attacker full access to the Node-RED server where they can run arbitrary commands on the underlying operating system.
KUNBUS has identified the following specific mitigations that users can apply to reduce risk:
* Update PiCtory package to version 2.12
The preferred method for updating to version 2.12 is accomplished through KUNBUS's management UI Cockpit. However, users can also download the update package here http://packages.revolutionpi.de/pool/main/p/pictory/ .
By end of April 2025, KUNBUS plans to release a new Cockpit plugin that helps the user to make configurations which are available in a graphical interface. In the meantime, it is recommended that users activate authentication. Please refer to this guide https://www.kunbus.com/files/media/misc/kunbus-2025-0000002-remediation.pdf for help with activating authentication.
