Summary

CVE-2026-63586 is a critical OS command injection vulnerability (CWE-78) in the web management interface of Weidmueller’s IE-SR-2TX-WL industrial security router series. The flaw allows a fully unauthenticated remote attacker to execute arbitrary commands as root on the device. It carries a CVSS v3.1 base score of 9.8 (Critical) and a CVSS v4.0 score of 9.3, reflecting network exploitability with no privileges or user interaction required.

Technical details

  • Root cause: the device’s web interface uses a modified uhttpd server with CGI shell scripts; the username supplied via HTTP Basic Authentication is taken directly from the Authorization header and inserted, unsanitized, into a shell command string executed via system().
  • Trigger condition: an attacker submits a specially crafted username containing shell metacharacters in the HTTP Basic Auth request to the device’s web management interface.
  • Attack vector: network — no authentication, prior access, or user interaction is required; low attack complexity.
  • Impact: full compromise of confidentiality, integrity, and availability, with arbitrary command execution at root privilege level on the router.

Affected software

  • Weidmueller IE-SR-2TX-WL (model 2682590000): firmware 1.52 up to but not including 1.57
  • Weidmueller IE-SR-2TX-WL-4G-EU (model 2682560000): firmware 1.67 up to but not including 1.74
  • Weidmueller IE-SR-2TX-WL-4G-US-V (model 2682580000): firmware 1.67 up to but not including 1.74

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical) — CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
  • CVSS v4.0 Base Score: 9.3 (Critical) — CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

Mitigation and recommended actions

  • Immediate: upgrade IE-SR-2TX-WL devices to firmware 1.57 or later, and IE-SR-2TX-WL-4G-EU / IE-SR-2TX-WL-4G-US-V devices to firmware 1.74 or later.
  • If patching is not immediately possible: restrict access to the device’s web management interface using firewall rules, access control lists, VPNs, or a dedicated management network, and ensure the interface is never exposed directly to the public internet.

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.
