In a Junos Fusion scenario an External Control of Critical State Data vulnerability in the Satellite Device (SD) control state machine of Juniper Networks Junos OS allows an attacker who is able to make physical changes to the cabling of the device to cause a denial of service (DoS). An SD can get rebooted and subsequently controlled by an Aggregation Device (AD) which does not belong to the original Fusion setup and is just connected to an extended port of the SD. To carry out this attack the attacker needs to have physical access to the cabling between the SD and the original AD. This issue affects: Juniper Networks Junos OS 16.1R1 and later versions prior to 18.4R3-S10; 19.1 versions prior to 19.1R3-S7; 19.2 versions prior to 19.2R3-S4. This issue does not affect Juniper Networks Junos OS versions prior to 16.1R1.

En un escenario de Junos Fusion, una vulnerabilidad de control externo de datos de estado críticos en la máquina de estado de control del dispositivo satélite (SD) del Sistema Operativo Junos de Juniper Networks permite a un atacante que sea capaz de realizar cambios físicos en el cableado del dispositivo causar una denegación de servicio (DoS). Un SD puede ser reiniciado y posteriormente controlado por un dispositivo de agregación (AD) que no pertenece a la configuración original de Fusion y que sólo está conectado a un puerto extendido del SD. Para llevar a cabo este ataque, el atacante necesita tener acceso físico al cableado entre el SD y el AD original. Este problema afecta: Juniper Networks Junos OS 16.1R1 y versiones posteriores, anteriores a 18.4R3-S10; versiones 19.1 anteriores a 19.1R3-S7; versiones 19.2 anteriores a 19.2R3-S4. Este problema no afecta a versiones de Junos OS de Juniper Networks anteriores a 16.1R1
