Descriptions

The Use of a Hard-coded Cryptographic Key vulnerability in Juniper Networks Juniper Cloud Native Router (JCNR) and containerized routing Protocol Deamon (cRPD) products allows an attacker to perform Person-in-the-Middle (PitM) attacks which results in complete compromise of the container. Due to hardcoded SSH host keys being present on the container, a PitM attacker can intercept SSH traffic without being detected. This issue affects Juniper Networks JCNR: * All versions before 23.4. This issue affects Juniper Networks cRPD: * All versions before 23.4R1.

La vulnerabilidad del uso de una clave criptográfica codificada en Juniper Networks Juniper Cloud Native Router (JCNR) y los productos de protocolo de enrutamiento en contenedores Deamon (cRPD) permite a un atacante realizar ataques de persona en el medio (PitM) que resultan en un compromiso total del contenedor. Debido a que las claves de host SSH codificadas están presentes en el contenedor, un atacante de PitM puede interceptar el tráfico SSH sin ser detectado. Este problema afecta a Juniper Networks JCNR: * Todas las versiones anteriores a la 23.4. Este problema afecta al cRPD de Juniper Networks: * Todas las versiones anteriores a 23.4R1.
