SIMATIC IoT2050 Node-RED Auth Bypass (V4.3.4.0) Arbitrary System Exec
CVE-2026-58115 Published on August 11, 2026
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.
Weakness Type
Missing Authentication for Critical Function
The software does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
Affected Versions
Siemens SIMATIC IoT2050 Advanced:- Before V4.3.4.1 is affected.
