Unitree G1 EDU 1.5.2 Unauthenticated RCE via DDS Bridge and Path Traversal

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-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

CWE-306 Missing Authentication for Critical Function

The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
