4. MITIGATIONS

alpitronic recommends users change the default credentials for all charging devices.

alpitronic advises that the interface should be connected only to internal segregated and access-controlled networks and not exposed to the public internet/web.

When informed of these vulnerabilities, alpitronic, in conjunction with and/or on behalf of affected clients, disabled the interface on any exposed devices and all clients were contacted directly and reminded that the interface is not intended to be visible on the public Internet and that default passwords should be changed.

alpitronic are also applying mitigations to all devices in the field and to new devices in production. New devices will come with unique passwords. Devices using the default password will be automatically assigned new unique passwords, or at first access if the device has not yet been installed. Devices with the default passwords already changed will not be affected. New passwords can be obtained by scanning the QR-Code inside the charger or in DMS portal hyperdoc. Contact Hypercharger support with any questions about newly assigned passwords.

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as:

Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
