Summary
Phoenix Contact: Security Advisory for CHARX SEC-3xxx charging controllers
Severity
Critical
Notes
Summary: Multiple vulnerabilities in the firmware of CHARX SEC-3xxx charging controllers have been discovered. **Update Version 1.1.0:** Updated the reporting credits for CVE-2025-25271.
Impact: The vulnerabilities can lead to a total loss of confidentiality, integrity and availability of the devices.
Mitigation: Affected charging controllers are designed and developed for the use in closed industrial networks. Phoenix Contact therefore strongly recommends using the devices exclusively in closed networks and protected by a suitable firewall.
Remediation: Phoenix Contact strongly recommends to upgrade to firmware version 1.7.3 which fixes these vulnerabilities.
General Recommendation: For general information and recommendations on security measures to protect network-enabled devices, refer to the application note: [Application Note Security](https://dam-mdc.phoenixcontact.com/asset/156443151564/0a870ae433c19148b80bd760f3a1c1f2/107913_en_03.pdf).
