Technical description

A vulnerability has been identified in SIMATIC IoT2050 Advanced (6ES7647-0BA00-1YA2) (All versions < V4.3.4.1 running Industrial OS with Node-RED installed). Affected devices do not enforce authentication on the Node-RED HTTP interface, allowing unauthenticated access to programming nodes that are capable of executing system commands on the server.

This could allow an unauthenticated remote attacker to create malicious flows through the HTTP interface in order to execute arbitrary code on the underlying server with maximum privileges.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
