CVE-2018-0053
An authentication bypass vulnerability in the initial boot sequence of Juniper Networks Junos OS on vSRX Series may allow an attacker to gain full control of the system without authentication when the system is initially booted up.
Does this matter?
Lower severity and a low EPSS score (0.49%). Track it; it rarely justifies an emergency change on its own.
