Summary

CVE-2026-58115 is a critical missing-authentication vulnerability (CWE-306) affecting the Node-RED HTTP interface bundled with Siemens SIMATIC IoT2050 Advanced devices running the Industrial OS. The Node-RED editor/admin API is exposed without any access control, allowing an unauthenticated network attacker to deploy malicious flows and execute arbitrary code with the highest privileges on the underlying server. The flaw carries the maximum CVSS v3.1 and v4.0 scores of 10.0.

Technical details

  • Root cause: The Node-RED HTTP interface on affected devices ships without authentication enabled, leaving the editor and admin API reachable to anyone who can reach the device over the network.
  • Trigger conditions: No credentials, prior access, or user interaction are required; the attacker only needs network access to the exposed HTTP interface.
  • Attack vector: Network (remote, unauthenticated).
  • Impact: An attacker can create and deploy malicious Node-RED flows containing function nodes that execute system commands, resulting in arbitrary code execution with maximum privileges (full compromise of confidentiality, integrity, and availability).

Affected software

  • SIMATIC IoT2050 Advanced (Model 6ES7647-0BA00-1YA2) running Industrial OS with Node-RED installed: all versions prior to V4.3.4.1.

Severity

  • CVSS v3.1 Base Score: 10.0 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
  • CVSS v4.0 score is also 10.0.

Mitigation and recommended actions

  • Immediate: Update the affected device to Industrial OS version V4.3.4.1 or later, which resolves the issue.
  • If patching is not immediately possible:
    • Uninstall Node-RED from the device if it is not required.
    • Apply Node-RED’s official security hardening guidance to enable authentication on the editor/admin HTTP interface.
    • Restrict network access to the device (e.g., segment it off untrusted networks, limit exposure via firewall rules) and follow Siemens’ general operational security recommendations for industrial devices.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
