CVE-2018-0035
Status: ModifiedCritical (9.8)—
QFX5200 and QFX10002 devices that have been shipped with Junos OS 15.1X53-D21, 15.1X53-D30, 15.1X53-D31, 15.1X53-D32, 15.1X53-D33 and 15.1X53-D60 or have been upgraded to these releases using the .bin or .iso images may contain an unintended additional Open Network Install Environment (ONIE) partition. This additional partition allows the superuser to reboot to the ONIE partition which will wipe out the content of the Junos partition and its configuration.
Read full descriptionShow less
Once rebooted, the ONIE partition will not have root password configured, thus any user can access the console or SSH, using an IP address acquired from DHCP, as root without password. Once the device has been shipped or upgraded with the ONIE partition installed, the issue will persist. Simply upgrading to higher release via the CLI will not resolve the issue. No other Juniper Networks products or platforms are affected by this issue.

Esta partición adicional permite que el superusuario reinicie en la partición ONIE, lo que eliminará el contenido de la partición Junos y su configuración. Una vez reiniciada, la partición ONIE no tendrá contraseña root configurada, por lo que cualquier usuario podría acceder como root a la consola a la consola o SSH mediante una dirección IP adquirida desde DHCP. Una vez el dispositivo ha sido distribuido o actualizado con la partición ONIE instalada, el problema persistirá. La simple actualización a una versión superior mediante la interfaz de línea de comandos no resolverá este problema. No hay ningún otro producto o plataforma de Juniper Networks que se vea afectado por este problema."
