Description
The vulnerability allows an attacker to compromise the affected system.
The vulnerability exists due to improperly imposed security restrictions on the console port. When "set system ports console insecure" is enabled, root login is disallowed for Junos OS as expected. However, the root password can be changed using "set system root-authentication plain-text-password" on NFX Series systems, leading to a possible administrative bypass with physical access to the console.
Remediation
Install updates from vendor's website.
