Siemens SIMATIC IoT2050 Advanced

View CSAF Summary SIMATIC IoT2050 Advanced devices running Industrial OS with Node-RED installed contain a missing authentication vulnerability in the Node-RED HTTP interface that could allow an unauthenticated remote attacker to create malicious flows and execute arbitrary code on the underlying server with maximum privileges. Siemens has released a new version for SIMATIC IoT2050 Advanced and strongly recommends to update to the latest version. The following versions of Siemens SIMATIC IoT2050 Advanced are affected: SIMATIC IoT2050 Advanced (6ES7647-0BA00-1YA2) vers:intdot/<4.3.4.1 CVSS Vendor Equipment Vulnerabilities v3 10 Siemens Siemens SIMATIC IoT2050 Advanced Missing Authentication for Critical Function Background Critical Infrastructure Sectors: Chemical, Critical Manufacturing, Energy, Transportation Systems Countries/Areas Deployed: Worldwide Company Headquarters Location: Germany Vulnerabilities Expand All + CVE-2026-58115 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.

Recommended Practices CISA recommends users take defensive measures to minimize the exploitation risk of these vulnerabilities. Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolate them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most recent version available. Also recognize VPN is only as secure as its connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the I
