CyberRota Analysis

AI-Generated

The vulnerability affects the Unitree G1 EDU firmware, specifically in the BLE GATT server and WiFi provisioning stack, allowing unauthenticated attackers in proximity to execute arbitrary root code. By exploiting a buffer overflow and an unquoted heredoc variable in the WiFi provisioning script, attackers can manipulate the system to execute commands with elevated privileges. Organizations using this firmware should prioritize patching to mitigate the risk of unauthorized access and potential system compromise.

Original NVD Description

Unitree G1 EDU firmware through 1.5.2 contains multiple chained vulnerabilities in the BLE GATT server and WiFi provisioning stack that allow unauthenticated proximate attackers to achieve root code execution without pairing or credentials by exploiting an unquoted heredoc variable in the WiFi provisioning script and a buffer overflow in the SSID chunk accumulator. Attackers can send crafted BLE writes to overflow a fixed BSS buffer across BLE connections, corrupting an adjacent mainloop function pointer dispatch entry that is subsequently invoked by the cleanup path passing attacker-controlled data to system() as uid 0.
