U

nitree Go2 firmware versions V1.1.7 through V1.1.9 and V1.1.11 (EDU) do not implement DDS authentication or authorization for the Eclipse CycloneDDS topic rt/api/programming_actuator/request handled by actuator_manager.py. A network-adjacent, unauthenticated attacker can join DDS domain 0 and publish a crafted message (api_id=1002) containing arbitrary Python, which the robot writes to disk under /unitree/etc/programming/ and binds to a physical controller keybinding. When the keybinding is pressed, the code executes as root and the binding persists across reboots.

Summary		(es) Las versiones de firmware de Unitree Go2 V1.1.7 a V1.1.9 y V1.1.11 (EDU) no implementan autenticación ni autorización DDS para el tema de Eclipse CycloneDDS rt/api/programming_actuator/request gestionado por actuator_manager.py. Un atacante adyacente a la red y no autenticado puede unirse al dominio DDS 0 y publicar un mensaje manipulado (api_id=1002) que contiene Python arbitrario, el cual el robot escribe en el disco bajo /unitree/etc/programming/ y lo vincula a una asignación de teclas de un controlador físico. Cuando se pulsa la asignación de teclas, el código se ejecuta como root y la vinculación persiste a través de los reinicios.
