Patch information

External protective measures are required: Disable the webserver after configuration, if possible, by following these steps: - Enable SSH via the web server. - Login to the SSH server. - Disable the webserver via SSH portal. - Reboot the device. or: - Use HTTPS rather than HTTP while using the webserver. - Minimize network exposure for affected products and ensure that they are not accessible via the Internet. - Isolate affected products from the corporate network. - If remote access is required, use secure methods such as virtual private networks(VPNs). Pepperl+Fuchs will provide an update to address some of these vulnerabilities in the future.

IACS Radar priority score

38/ 100

Based on CVSS 4.0, EPSS 32.2%, industrial relevance 40/100.

Combines CVSS, EPSS, KEV status, industrial relevance and exposure relevance — a complement to, not a replacement for, the individual scores below and above.

Conditions for exploitation

•Local or adjacent access to the device is required.
•No valid credentials are needed.
•No user interaction required.

Operational impact & energy relevance

Limited impact on availability; the risk lies mainly with confidentiality or integrity of process data.

No strong energy-sector-specific signals recognised; general OT/ICS relevance.

Recommended defensive measures

•Encrypt sensitive configuration and management communication.
•Restrict network access to the affected device to a dedicated OT management segment.
•Implement network segmentation in line with zones and conduits (IEC 62443-3-2).
•Monitor for abnormal protocol traffic using an OT-aware detection system.

Industrial relevance score

40/ 100

• Mentioned in an official CISA ICS advisory, which confirms direct relevance to industrial control systems.

Classification is provisional; manual verification by an OT security analyst is recommended.

Classified by IACS Radar-analysepijplijn (geautomatiseerd) on 7 November 2026.
