Descriptions

An Improper Check for Unusual or Exceptional Conditions vulnerability in Routing Protocol Daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based, unauthenticated attacker to cause rpd to crash, leading to Denial of Service (DoS).

On all Junos OS and Junos OS Evolved platforms, when NETCONF and gRPC are enabled, and a specific query is executed via Dynamic Rendering (DREND), rpd will crash and restart. Continuous execution of this specific query will cause a sustained Denial of Service (DoS) condition.

This issue affects:

Juniper Networks Junos OS

* 22.2 versions earlier than 22.2R2-S2, 22.2R3;
* 22.3 versions earlier than 22.3R2, 22.3R3.

Juniper Networks Junos OS Evolved

* 22.2 versions earlier than 22.2R2-S2-EVO, 22.2R3-EVO;
* 22.3 versions earlier than 22.3R2-EVO, 22.3R3-EVO.

This issue does not affect Juniper Networks:

Junos OS versions earlier than 22.2R1;

Junos OS Evolved versions earlier than 22.2R1-EVO.

Una vulnerabilidad de verificación inadecuada de condiciones inusuales o excepcionales en Routing Protocol Daemon (RPD) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante no autenticado basado en la red cause que rpd falle, lo que lleva a una denegación de servicio (DoS). En todas las plataformas Junos OS y Junos OS Evolved, cuando NETCONF y gRPC están habilitados y se ejecuta una consulta específica mediante representación dinámica (DREND), rpd fallará y se reiniciará. La ejecución continua de esta consulta específica provocará una condición sostenida de Denegación de Servicio (DoS). Este problema afecta a: Juniper Networks Junos OS * 22.2 versiones anteriores a 22.2R2-S2, 22.2R3; * Versiones 22.3 anteriores a 22.3R2, 22.3R3. Juniper Networks Junos OS Evolved * 22.2 versiones anteriores a 22.2R2-S2-EVO, 22.2R3-EVO; * Versiones 22.3 anteriores a 22.3R2-EVO, 22.3R3-EVO. Este problema no afecta a Juniper Networks: versiones de Junos OS anteriores a 22.2R1; Versiones de Junos OS Evolved anteriores a 22.2R1-EVO.
