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.
