CVE-2018-0021
Estado: ModificadaAlta (8.8)—
Si no se configuran todos los 64 dígitos del nombre de la clave de asociación de conectividad (CNK) o todos los 32 dígitos de la clave de asociación de conectividad (CAK), el resto de dígitos se configurarán automáticamente a 0. Por lo tanto, los dispositivos Juniper configurados con claves MacSec cortas están en riesgo de que sea más probable que un atacante descubra las frases de contraseñas secretas configuradas para estas claves a través de ataques basados en diccionario y de fuerza bruta mediante paquetes suplantados.
