Title
Unitree Go2 Missing DDS Authentication Enables Adjacent RCE
Summary
Unitree 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.
Severity ?
8.5 (High)
