CWE-ID:
CWE-264
Exploitation vector: Local
Exploit availability: No
Vulnerable software:
Juniper Junos OS
Operating systems & Components /
Operating system
Vendor: Juniper Networks, Inc.
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.
Mitigation
Install updates from vendor's website.
