CVE-2022-0878 is a medium-severity flaw (CVSS 4.6) affecting combined charging system firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Electric Vehicle (EV) commonly utilises the Combined Charging System (CCS) for DC rapid charging. To exchange important messages such as the State of Charge (SoC) with the Electric Vehicle Supply Equipment (EVSE) CCS uses a high-bandwidth IP link provided by the HomePlug Green PHY (HPGP) power-line communication (PLC) technology. The attack interrupts necessary control communication between the vehicle and charger, causing charging sessions to ab
