Summary
Autel MaxiCharger AC Wallbox Commercial DLB_SlaveRegister Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Autel MaxiCharger AC Wallbox Commercial EV chargers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of DLB_SlaveRegister messages. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-26327.

Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar c\u00f3digo arbitrario en las instalaciones afectadas de cargadores de veh\u00edculos el\u00e9ctricos Autel MaxiCharger AC Wallbox Commercial. No se requiere autenticaci\u00f3n para explotar esta vulnerabilidad. La falla espec\u00edfica se encuentra en el manejo de los mensajes DLB_SlaveRegister. El problema se debe a la falta de una validaci\u00f3n adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos a un b\u00fafer basado en el heap de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar c\u00f3digo en el contexto del dispositivo. Era ZDI-CAN-26327."
