AI-suggested

If you cannot patch yet, restrict network access to the Node-RED HTTP interface to trusted users only and consider disabling Node-RED if not required.

Description

A critical vulnerability exists in SIMATIC IoT2050 Advanced devices running Industrial OS with Node-RED installed, affecting all versions prior to V4.3.4.1. The issue arises because the Node-RED HTTP interface does not enforce authentication, allowing unauthenticated remote attackers to access programming nodes. This access enables attackers to create malicious flows that execute arbitrary system commands with maximum privileges on the underlying server.
