Forwarding Engine (PFE) de Juniper Networks Junos OS en la serie MX permite a un atacante no autenticado basado en la red eludir las restricciones de acceso previstas. En un escenario de Abstracted Fabric (AF), si se configuran instancias de enrutamiento (RI), el tr\u00e1fico v\u00e1lido espec\u00edfico destinado al dispositivo puede omitir los filtros de firewall lo0 configurados, ya que se recibe en el contexto de RI incorrecto.
