Notes

General Security Recommendations
We strongly recommend the following industry cybersecurity best practices. https://www.se.com/us/en/download/document/7EN52-0390/ * Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network. * Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks. * Place all controllers in locked cabinets and never leave them in the “Program” mode. * Never connect programming software to any network other than the network intended for that device. * Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks. * Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation. * Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet. * When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices. For more information refer to the Schneider Electric Recommended Cybersecurity Best Practices document.
For More Information
This document provides an overview of the identified vulnerability or vulnerabilities and actions required to mitigate.

Overview
Schneider Electric is aware of multiple vulnerabilities in its EVlink City, Parking, and Smart Wallbox products. The EVlink products are electric vehicle (EV) charging stations for private properties, semi-public car parks and on-street charging. These vulnerabilities can be exploited by obtaining physical access either to the charging station’s internal communication port, which requires disassembling the charging station enclosure, or, in the case of a connected station, to the network of the charging station’s supervision system. The risk is further elevated when the connected stations are accessible over the internet and have insufficient network security measures. Customers should immediately apply the available remediations. Failure to do so may risk potential unauthorized access to the charging station’s web server, which could lead to tampering and compromise of the charging station’s settings and accounts. Such tampering could lead to things like denial of service attacks, which could result in unauthorized use of the charging station, service interruptions, failure to send charging data records to the supervision system and the modification and disclosure of the charging station’s configuration. In addition to applying the available remediations to limit the risk of a connected charging station being compromised, Schneider Electric recommends that customers follow and apply network security best practices and ensure that the charging stations are not accessible from the internet, as outlined in the General Security Recommendations section. For additional information and support, please contact your Schneider Electric sales or service representative or Schneider Electric’s Customer Care Center. https://www.se.com/ww/en/product-category/1800-electric-vehicle-%28ev%29-charging/
Recommendations for End of Life Offers
EVlink Parking products with references EVF1 / EVW1 and EVlink City products with references EVC1S22P3 / EVC1S7P3 or older have reached their end of life and are no longer supported. Customers should consider replacing the charging station by the latest EVlink Parking and EVlink City product offering to resolve these issues. Always follow the recommendations provided in the General Security Recommendations section below in order to harden the security of the network where the charging station is connected (in case of a supervised station) and ensure that the station is not reachable from outside this network.
