Thus, an attacker will likely only be able to find this vulnerability by reverse-engineering the firmware or trying it on all <redacted> fields. The attacker will also need a (low privilege) account to gain access to the <redacted> binary, or convince a user with such access to execute a payload.\n\nImpact: Critical \u2013 The attacker has full control over the charging station as the root user, and can arbitrarily add, modify and delete files and services.\n\nCVSS 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). If is a full system compromise, potentially fully compromising confidentiality, integrity and availability of the devicer (VC:H/VI:H/VA:H).\u00a0 A compromised charger can be used to \"pivot\" onto networks that should otherwise be closed, cause a low confidentiality and interity impact on subsequent systems. (SC:L/SI:L/SA:H).\u00a0Because this device is an EV charger handing significant amounts of power, we suspect this vulnerability can have a safety impact (S:P).

Este problema afecta al firmware de Iocharger para modelos de aire acondicionado anteriores a la versi\u00f3n 24120701. Probabilidad: moderada: esta acci\u00f3n no es un lugar com\u00fan para que se produzcan vulnerabilidades de inyecci\u00f3n de comandos. Por lo tanto, es probable que un atacante solo pueda encontrar esta vulnerabilidad mediante ingenier\u00eda inversa del firmware o prob\u00e1ndola en todos los campos . El atacante tambi\u00e9n necesitar\u00e1 una cuenta (con privilegios bajos) para obtener acceso al binario o convencer a un usuario con dicho acceso para que ejecute un payload.

Aclaraci\u00f3n de CVSS. El ataque se puede ejecutar a trav\u00e9s de cualquier conexi\u00f3n de red que la estaci\u00f3n est\u00e9 escuchando y que sirva a la interfaz web (AV:N), y no hay ninguna medida de seguridad adicional que se deba eludir (AC:L), el ataque no depende de condiciones previas (AT:N). El ataque requiere autenticaci\u00f3n, pero el nivel de autenticaci\u00f3n es irrelevante (PR:L), no requiere interacci\u00f3n del usuario (UI:N). Se trata de un compromiso total del sistema, que potencialmente compromete por completo la confidencialidad, integridad y disponibilidad del dispositivo (VC:H/VI:H/VA:H). Un cargador comprometido se puede utilizar para \"pivotar\" hacia redes que de otro modo deber\u00edan estar cerradas, lo que causa un impacto bajo en la confidencialidad e interidad de los sistemas posteriores (SC:L/SI:L/SA:H). Debido a que este dispositivo es un cargador EV que gestiona cantidades significativas de energ\u00eda, sospechamos que esta vulnerabilidad puede tener un impacto en la seguridad (S:P).
