      "value": "ChargePoint Home Flex revssh Service Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of ChargePoint Home Flex devices. Authentication is not required to exploit this vulnerability.\n\nThe specific flaw exists within the handling of OCPP messages. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-26338."

Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de dispositivos ChargePoint Home Flex. La autenticación no es necesaria para explotar esta vulnerabilidad.\n\nLa falla específica reside en el manejo de mensajes OCPP. El problema se debe a la falta de validación adecuada de una cadena proporcionada por el usuario antes de usarla para ejecutar una llamada al sistema. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de root. Fue ZDI-CAN-26338."
