Descriptions
A vulnerability in the NETISR network queue functionality of Juniper Networks Junos OS kernel allows an attacker to cause a Denial of Service (DoS) by sending crafted genuine packets to a device. During an attack, the routing protocol daemon (rpd) CPU may reach 100% utilization, yet FPC CPUs forwarding traffic will operate normally. This attack occurs when the attackers' packets are sent over an IPv4 unicast routing equal-cost multi-path (ECMP) unilist selection. Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition. An indicator of compromise may be to monitor NETISR drops in the network with the assistance of JTAC. Please contact JTAC for technical support for further guidance. This issue affects: Juniper Networks Junos OS 17.3 version 17.3R3-S9 and later versions prior to 17.3R3-S12; 17.4 version 17.4R3-S3 and later versions prior to 17.4R3-S5; 18.1 version 18.1R3-S11 and later versions prior to 18.1R3-S13; 18.2 version 18.2R3-S6 and later versions; 18.3 version 18.3R3-S4 and later versions prior to 18.3R3-S5; 18.4 version 18.4R3-S5 and later versions prior to 18.4R3-S9; 19.1 version 19.1R3-S3 and later versions prior to 19.1R3-S7. This issue does not affect Juniper Networks Junos OS versions prior to 17.3R3-S9. This issue does not affect Juniper Networks Junos OS Evolved.
Una vulnerabilidad en la funcionalidad NETISR network queue del kernel del Sistema Operativo Junos de Juniper Networks permite a un atacante causar una denegación de servicio (DoS) mediante el envío de paquetes genuinos diseñados a un dispositivo. Durante un ataque, la CPU del demonio del protocolo de enrutamiento (rpd) puede alcanzar el 100% de uso, aunque las CPU de la FPC que reenvían el tráfico funcionarán normalmente. Este ataque es producido cuando los paquetes de los atacantes son enviados a través de una selección unilista de enrutamiento IPv4 unicast de igual coste y múltiples rutas (ECMP). La recepción y el procesamiento continuos de estos paquetes crearán una condición sostenida de denegación de servicio (DoS). Un indicador de compromiso puede ser monitorear las caídas de NETISR en la red con la ayuda de JTAC. Por favor, póngase en contacto con el JTAC para el apoyo técnico para obtener más orientación. Este problema afecta: Juniper Networks Junos OS 17.3 versión 17.3R3-S9 y versiones posteriores anteriores a 17.3R3-S12; 17.4 versión 17.4R3-S3 y versiones posteriores anteriores a 17.4R3-S5; 18.1 versión 18.1R3-S11 y versiones posteriores anteriores a 18.1R3-S13; 18. 2 versión 18.2R3-S6 y versiones posteriores; 18.3 versión 18.3R3-S4 y versiones posteriores anteriores a 18.3R3-S5; 18.4 versión 18.4R3-S5 y versiones posteriores anteriores a 18.4R3-S9; 19.1 versión 19.1R3-S3 y versiones posteriores anteriores a 19.1R3-S7. Este problema no afecta a versiones del Sistema Operativo Junos de Juniper Networks anteriores a 17.3R3-S9. Este problema no afecta a Juniper Networks Junos OS Evolved
