Descriptions

A vulnerability in class-of-service (CoS) queue management in Juniper Networks Junos OS on the ACX2K Series devices allows an unauthenticated network-based attacker to cause a Denial of Service (DoS). Specific packets are being incorrectly routed to a queue used for other high-priority traffic such as BGP, PIM, ICMP, ICMPV6 ND and ISAKMP. Due to this misclassification of traffic, receipt of a high rate of these specific packets will cause delays in the processing of other traffic, leading to a Denial of Service (DoS). Continued receipt of this amount of traffic will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS on ACX2K Series: All versions prior to 19.4R3-S9; All 20.2 versions; 20.3 versions prior to 20.3R3-S6 on ACX2K Series; 20.4 versions prior to 20.4R3-S4 on ACX2K Series; All 21.1 versions; 21.2 versions prior to 21.2R3-S3 on ACX2K Series. Note: This issues affects legacy ACX2K Series PPC-based devices. This platform reached Last Supported Version (LSV) as of the Junos OS 21.2 Release.

Una vulnerabilidad en la gestión de colas Class-of-Service (CoS) en Juniper Networks Junos OS en los dispositivos de la serie ACX2K permite que un atacante basado en red no autenticado provoque una denegación de servicio (DoS). Paquetes específicos se enrutan incorrectamente a una cola utilizada para otro tráfico de alta prioridad, como BGP, PIM, ICMP, ICMPV6 ND e ISAKMP. Debido a esta clasificación errónea del tráfico, la recepción de una tasa elevada de estos paquetes específicos provocará retrasos en el procesamiento de otro tráfico, lo que provocará una denegación de servicio (DoS). La recepción continua de esta cantidad de tráfico creará una condición sostenida de Denegación de Servicio (DoS). Este problema afecta a Juniper Networks Junos OS en la serie ACX2K: todas las versiones anteriores a 19.4R3-S9; Todas las versiones 20.2; Versiones 20.3 anteriores a 20.3R3-S6 en la serie ACX2K; Versiones 20.4 anteriores a 20.4R3-S4 en la serie ACX2K; Todas las versiones 21.1; Versiones 21.2 anteriores a 21.2R3-S3 en la serie ACX2K. Nota: Este problema afecta a los dispositivos heredados basados en PPC de la serie ACX2K. Esta plataforma alcanzó la última versión admitida (LSV) a partir de la versión Junos OS 21.2.
