CVE-2023-32157

Tesla Model 3 bsa_server BIP Heap-based Buffer Overflow Arbitrary Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected Tesla Model 3 vehicles. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability. The specific flaw exists within the bsa_server process. 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 an unprivileged user in a sandboxed process. . Was ZDI-CAN-20737.

Summary		(es) Vulnerabilidad de ejecución de código arbitrario de desbordamiento de búfer de almacenamiento dinámico BIP del Tesla Model 3 bsa_server. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en los vehículos Tesla Model 3 afectados. Un atacante primero debe obtener la capacidad de emparejar un dispositivo Bluetooth malicioso con el sistema de destino para poder aprovechar esta vulnerabilidad. La falla específica existe dentro del proceso bsa_server. El problema se debe a la falta de una validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos en un búfer basado en montón de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de un usuario sin privilegios en un proceso de espacio aislado. Era ZDI-CAN-20737.
