"value": "A replay attack vulnerability was discovered in a Zigbee smart home kit manufactured by Ksix (Zigbee Gateway Module = v1.0.3, Door Sensor = v1.0.7, Motion Sensor = v1.0.12), where the Zigbee anti-replay mechanism - based on the frame counter field - is improperly implemented. As a result, an attacker within wireless range can resend captured packets with a higher sequence number, which the devices incorrectly accept as legitimate messages. This allows spoofed commands to be injected without authentication, triggering false alerts and misleading the user through notifications in the mobile application used to monitor the network."

"value": "Se descubri\u00f3 una vulnerabilidad de ataque de repetici\u00f3n en Zigbee smart home kit manufactured by Ksix (Zigbee Gateway Module = v1.0.3, Door Sensor = v1.0.7, Motion Sensor = v1.0.12), donde el mecanismo antirreproducci\u00f3n de Zigbee, basado en el campo contador de tramas, est\u00e1 implementado incorrectamente. Como resultado, un atacante dentro del alcance inal\u00e1mbrico puede reenviar paquetes capturados con un n\u00famero de secuencia mayor, que los dispositivos aceptan incorrectamente como mensajes leg\u00edtimos. Esto permite inyectar comandos falsificados sin autenticaci\u00f3n, lo que genera alertas falsas y enga\u00f1a al usuario mediante notificaciones en la aplicaci\u00f3n m\u00f3vil utilizada para monitorear la red."
