Summary
There are many buffer overflow vulnerabilities present in several CGI binaries of the charging station.This issue affects Iocharger firmware for AC model chargers beforeversion 24120701.
Likelihood: High – Given the prevalence of these buffer overflows, and the clear error message of the web server, an attacker is very likely to be able to find these vulnerabilities.
Impact: Low – Usually, overflowing one of these buffers just causes a segmentation fault of the CGI binary, which causes the web server to return a 502 Bad Gateway error. However the webserver itself is not affected, and no DoS can be achieved. Abusing these buffer overflows in a meaningful way requires highly technical knowledge, especially since ASLR also seems to be enabled on the charging station. However, a skilled attacker might be able to use one of these buffer overflows to obtain remote code execution.
CVSS clarification. The attack can be executed over any network connection the station is listening to and serves the web interface (AV:N), and there are no additional security measure sin place that need to be circumvented (AC:L), the attack does not rely on preconditions (AT:N). The attack does require authentication, but the level of authentication is irrelevant (PR:L), it does not require user interaction (UI:N). The attack has a small impact on the availability of the device (VC:N/VI:N/VA:L). There is no impact on subsequent systems. (SC:N/SI:N/SA:N). While this device is an EV charger handing significant amounts of power, we do not expect this vulnerability to have a safety impact. The attack can be automated (AU:Y).

Este problema afecta al firmware de Iocharger para cargadores de modelos de CA anteriores a la versión 24120701. Probabilidad: Alta: dada la prevalencia de estos desbordamientos de búfer y el claro mensaje de error del servidor web, es muy probable que un atacante pueda encontrar estas vulnerabilidades. Impacto: Bajo: por lo general, el desbordamiento de uno de estos búferes solo provoca un error de segmentación del binario CGI, lo que hace que el servidor web devuelva un error 502 Bad Gateway. Sin embargo, el servidor web en sí no se ve afectado y no se puede lograr ningún ataque de denegación de servicio. Abusar de estos desbordamientos de búfer de una manera significativa requiere un alto nivel de conocimientos técnicos, especialmente porque ASLR también parece estar habilitado en la estación de carga. Sin embargo, un atacante experto podría ser capaz de utilizar uno de estos desbordamientos de búfer para obtener la ejecución remota de código. Aclaración de CVSS. El ataque se puede ejecutar a través de cualquier conexión de red que la estación esté escuchando y que sirva a la interfaz web (AV:N), y no existen medidas de seguridad adicionales que se deban eludir (AC:L), el ataque no depende de condiciones previas (AT:N). El ataque requiere autenticación, pero el nivel de autenticación es irrelevante (PR:L), no requiere interacción del usuario (UI:N). El ataque tiene un pequeño impacto en la disponibilidad del dispositivo (VC:N/VI:N/VA:L). No hay impacto en los sistemas posteriores (SC:N/SI:N/SA:N). Si bien este dispositivo es un cargador de vehículos eléctricos que gestiona cantidades significativas de energía, no esperamos que esta vulnerabilidad tenga un impacto en la seguridad.
