"value": "A door-unlocking issue was discovered on Software House iStar Ultra devices through 6.5.2.20569 when used in conjunction with the IP-ACM Ethernet Door Module. The communications between the IP-ACM and the iStar Ultra is encrypted using a fixed AES key and IV. Each message is encrypted in CBC mode and restarts with the fixed IV, leading to replay attacks of entire messages. There is no authentication of messages beyond the use of the fixed AES key, so message forgery is also possible."

"value": "Se ha descubierto un problema de desbloqueo de puertas en dispositivos Software House iStar Ultra hasta la versi\u00f3n 6.5.2.20569 cuando se usan en conjunto con IP-ACM Ethernet Door Module. Las comunicaciones entre el IP-ACM y el iStar Ultra se cifran empleando una clave AES fija e IV. Cada mensaje se cifra en modo CBC y reinicia con el IV fijo, lo que conduce a ataques de reproducci\u00f3n de mensajes completos. No hay autenticaci\u00f3n de mensajes m\u00e1s all\u00e1 del uso de la clave AES fija, por lo que tambi\u00e9n es posible falsificar mensajes."
