How to fix CVE-2025-41742?

Within 24 hours: Inventory all SPRECON-E-C, SPRECON-E-P, and SPRECON-E-T3 devices; isolate affected systems from external networks if operationally feasible; enable enhanced logging. Within 7 days: Change all default cryptographic keys and credentials; implement network segmentation to restrict device access; disable remote maintenance features if not operationally critical. Within 30 days: Deploy network-based anomaly detection on OT/ICS segments; conduct forensic review for unauthorized access; establish vendor communication protocol for patch notification.

Is Sprecon E C Firmware affected by CVE-2025-41742?

Sprecher Automation SPRECON industrial control systems are exposed to critical remote compromise via hardcoded default cryptographic keys, allowing unauthorized attackers to read/modify operational data and gain remote maintenance access without authentication.
