CVE-2022-0878— Novel attack against the Combined Charging System (CCS) in electric vehicles to remotely cause a denial of service

Novel attack against the Combined Charging System (CCS) in electric vehicles to remotely cause a denial of service

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 abort. The attack can be conducted wirelessly from a distance using electromagnetic interference, allowing individual vehicles or entire fleets to be disrupted simultaneously. In addition, the attack can be mounted with off-the-shelf radio hardware and minimal technical knowledge. With a power budget of 1 W, the attack is successful from around 47 m distance. The exploited behavior is a required part of the HomePlug Green PHY, DIN 70121 & ISO 15118 standards and all known implementations exhibit it. In addition to electric cars, Brokenwire affects electric ships, airplanes and heavy duty vehicles utilising these standards.

关键功能的认证机制缺失

Combined Charging System 访问控制错误漏洞

Combined Charging System（CCS）是一个组合充电系统。 Combined Charging System (CCS) for DC存在安全漏洞，攻击可以使用电磁干扰从远处以无线方式中断了车辆和充电器之间必要的控制通信，导致充电会话中止，从而可以同时破坏单个车辆或整个车队。
