CVE-2026-58115 in SIMATIC IoT2050 Advanced
Summary
by MITRE • 08/11/2026
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.

The vulnerability identified in SIMATIC IoT2050 Advanced devices represents a critical security flaw that undermines the fundamental integrity of industrial edge computing platforms. This device, specifically model 6ES7647-0BA00-1YA2, operates within the Siemens industrial automation ecosystem and serves as a gateway for various industrial IoT applications. The affected versions prior to V4.3.4.1 running Industrial OS with Node-RED installed present a significant risk due to their failure to implement proper access controls on the Node-RED HTTP interface. This flaw creates an inherent security weakness that directly violates industry standards and best practices for industrial cybersecurity.
The technical implementation of this vulnerability stems from the absence of authentication mechanisms within the Node-RED web interface component. Node-RED is a popular flow-based development tool designed for visual programming of event-driven applications, commonly used in IoT environments. When deployed on industrial devices like the SIMATIC IoT2050 Advanced, the HTTP interface should enforce strict access controls to prevent unauthorized system manipulation. However, this implementation flaw allows any remote attacker to bypass authentication requirements and gain direct access to the Node-RED programming environment. The CWE-287 weakness classification directly applies here as the system fails to properly authenticate users attempting to access protected resources.
The operational impact of this vulnerability extends far beyond simple unauthorized access, creating a potential pathway for complete system compromise. An unauthenticated remote attacker can leverage this vulnerability to create malicious flows through the HTTP interface and subsequently execute arbitrary code on the underlying server with maximum privileges. This privilege escalation capability means that attackers can perform actions equivalent to root or administrator level access, potentially leading to full system control, data exfiltration, or disruption of critical industrial processes. The ATT&CK framework categorizes this as a privilege escalation technique where an attacker moves from initial access to elevated system permissions without proper authorization.
The implications for industrial environments are particularly concerning given the nature of SCADA and IoT systems that often operate in closed networks with limited monitoring capabilities. The SIMATIC IoT2050 Advanced devices frequently serve as edge computing nodes that process sensitive operational data and control critical infrastructure components. This vulnerability creates an attack surface that could enable adversaries to compromise not just individual devices but potentially entire industrial networks if these devices are connected to broader systems. Organizations implementing these solutions must consider the cascading effects of such vulnerabilities, as they can facilitate lateral movement within industrial environments where traditional network segmentation may be insufficient.
Mitigation strategies for this vulnerability should begin with immediate firmware updates to version V4.3.4.1 or later, which presumably includes proper authentication enforcement on the Node-RED interface. Network segmentation and firewall rules should be implemented to restrict access to the Node-RED HTTP interface from untrusted networks, while also ensuring that only authorized personnel have legitimate access rights. Additionally, organizations should conduct comprehensive security assessments of their industrial IoT deployments to identify similar vulnerabilities in other edge devices. The implementation of principle of least privilege should be enforced where possible, limiting the functionality of Node-RED interfaces to only necessary components and disabling unnecessary features. Regular vulnerability scanning and continuous monitoring of industrial networks remain essential practices for detecting and mitigating similar security flaws across industrial control systems.
