Detailsinfo

A vulnerability classified as critical was found in Unitree Go2 and G1 up to 1.1.7. Affected by this vulnerability is an unknown functionality of the file wpa_supplicant_restart.sh of the component BLE Module. The manipulation with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Multiple robotic products by Unitree sharing a common firmware, including the Go2, G1, H1, and B2 devices, contain a command injection vulnerability. By setting a malicious string when configuring the on-board WiFi via a BLE module of an affected robot, then triggering a restart of the WiFi service, an attacker can ultimately trigger commands to be run as root via the wpa_supplicant_restart.sh shell script. All Unitree models use firmware derived from the same codebase (MIT Cheetah), and the two major forks are the G1 (humanoid) and Go2 (quadruped) branches.

The weakness was presented by Andreas Makris, Kevin Finisterre and Konstantin Severov. It is possible to read the advisory at takeonme.org. This vulnerability is known as CVE-2025-35027 since 04/15/2025. The exploitation appears to be easy. The attack can only be done within the local network.
