KUNBUS Revolution Pi Authentication Bypass by Primary Weakness
KUNBUS PiCtory versions 2.5.0 through 2.11.1 have an authentication bypass vulnerability where a remote attacker can bypass authentication to get access due to a path traversal.
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.
