RISK EVALUATION. Successful exploitation of this vulnerability could result in an attacker disabling the device, bypassing payment, or accessing payment data.
If misconfigured, the charging devices can expose a web interface protected by authentication.
If the default credentials are not changed, an attacker can use public knowledge to access the device as an administrator.
MITIGATIONS. alpitronic recommends users change the default credentials for all charging devices.
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.
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.
Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolating them from business networks.
Also recognize VPN is only as secure as the connected devices.
