An Improper Following of a Certificate's Chain of Trust vulnerability in J-Web of Juniper Networks Junos OS on SRX Series allows a PITM to intercept the communication of the device and get access to confidential information and potentially modify it. When an SRX device is provisioned to connect to Security Director (SD) cloud, it doesn't perform sufficient verification of the received server certificate. This allows a PITM to intercept the communication between the SRX and SD cloud and access credentials and other sensitive information. This issue affects Junos OS: * all versions before 22.4R3-S9, * 23.2 versions before 23.2R2-S6, * 23.4 versions before 23.4R2-S7, * 24.2 versions before 24.2R2-S3, * 24.4 versions before 24.4R2-S2, * 25.2 versions before 25.2R1-S2, 25.2R2.

Una vulnerabilidad de Seguimiento Incorrecto de la Cadena de Confianza de un Certificado en J-Web de Juniper Networks Junos OS en la Serie SRX permite a un PITM interceptar la comunicación del dispositivo y obtener acceso a información confidencial y potencialmente modificarla. Cuando un dispositivo SRX se aprovisiona para conectarse a la nube de Security Director (SD), no realiza una verificación suficiente del certificado de servidor recibido. Esto permite a un PITM interceptar la comunicación entre el SRX y la nube de SD y acceder a credenciales y otra información sensible. Este problema afecta a Junos OS: * todas las versiones anteriores a 22.4R3-S9, * versiones 23.2 anteriores a 23.2R2-S6, * versiones 23.4 anteriores a 23.4R2-S7, * versiones 24.2 anteriores a 24.2R2-S3, * versiones 24.4 anteriores a 24.4R2-S2, * versiones 25.2 anteriores a 25.2R1-S2, 25.2R2.
