Title
Unitree G1 EDU 1.5.2 Unauthenticated RCE via DDS Bridge and Path Traversal
Summary
Unitree G1 EDU firmware through 1.5.2 contains an unauthenticated remote code execution vulnerability that allows network-adjacent attackers to execute arbitrary commands as root by chaining three weaknesses: an unauthenticated WebRTC-to-DDS bridge on TCP port 9991, a static AES-128 key stored with world-readable permissions, and a path traversal flaw in the chat_go knowledge upload API. Attackers can publish DDS control messages to restart the bashrunner service, plant a malicious payload in its script execution directory via path traversal, and trigger execution of that payload as uid 0 through the bashrunner shell subprocess.
CWE
  • CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
  • CWE-306 - Missing Authentication for Critical Function
