All of the devices internet interfaces share a similar MAC address that only varies in their final octet. This allows network-adjacent attackers to derive the support user's SSH password by decrementing the final octet of the connected gateway address or via the BSSID. An attacker can then execute arbitrary OS commands with root-level privileges. NOTE: The vendor states that there is no intended functionality allowing an attacker to execute arbitrary OS Commands with root-level privileges. The vendor also states that this issue was fixed in SmartOS 12.5.5.1."}, {"lang": "es", "value": "Los dispositivos AdTran 834-5 HDC17600021F1 (SmartOS 11.1.1.1) habilitan el servicio SSH de forma predeterminada y tienen una cuenta de soporte oculta, indocumentada y codificada cuya contrase\u00f1a se basa en la direcci\u00f3n MAC del dispositivo. Todas las interfaces de Internet de los dispositivos comparten una direcci\u00f3n MAC similar que solo var\u00eda en su octeto final. Esto permite a los atacantes adyacentes a la red obtener la contrase\u00f1a SSH del usuario de soporte disminuyendo el octeto final de la direcci\u00f3n de la puerta de enlace conectada o mediante el BSSID.
