This issue appears to affect all of Unitree\u2019s current offerings as of February 26, 2026, and so should be considered a vulnerability in both the firmware generation and extraction processes. At the time of this release, there is no publicly-documented mechanism to subvert the update process and insert poisoned firmware packages without the equipment owner\u2019s knowledge."}, {"lang": "es", "value": "Dado que el algoritmo de cifrado utilizado para proteger las actualizaciones de firmware est\u00e1 a su vez cifrado utilizando material clave disponible para un atacante (o cualquiera que preste atenci\u00f3n), las actualizaciones de firmware pueden ser alteradas por un usuario no autorizado, y luego confiadas por un producto Unitree, como el Unitree Go2 y otros modelos. Este problema parece afectar a todas las ofertas actuales de Unitree a partir del 26 de febrero de 2026, y por lo tanto debe considerarse una vulnerabilidad tanto en los procesos de generaci\u00f3n como de extracci\u00f3n de firmware. En el momento de esta publicaci\u00f3n, no existe un mecanismo documentado p\u00fablicamente para subvertir el proceso de actualizaci\u00f3n e insertar paquetes de firmware envenenados sin el conocimiento del propietario del equipo."}], "lastModified": "2026-02-27T14:06:37.987", "sourceIdentifier": "[email protected]"}
