2020-04 Security Bulletin: NFX250 Series: Hardcoded credentials in the vSRX VNF instance. (CVE-2020-1614)
Article ID : JSA10997
Last Updated: 08 Apr 2020
Version : 3.0
Product Affected:
This issue affects Juniper Networks NFX Series Network Services Platform.
Affected platforms: NFX250 Series.
Problem:
A Use of Hard-coded Credentials vulnerability exists in the NFX250 Series for
the vSRX Virtual Network Function (VNF) instance, which allows an attacker to
take control of the vSRX VNF instance if they have the ability to access an
administrative service (e.g. SSH) on the VNF, either locally, or through the
network.
This issue only affects the NFX250 Series vSRX VNF. No other products or
platforms are affected.
This issue is only applicable to environments where the vSRX VNF root password
has not been configured.
This issue affects the Juniper Networks NFX250 Network Services Platform vSRX
VNF instance on versions prior to 19.2R1.
Juniper SIRT is not aware of any malicious exploitation of this vulnerability.
This issue was found during internal product security testing or research.
This issue has been assigned CVE-2020-1614 .
Solution:
The following software releases have been updated to resolve this specific
issue: NFX250 Series version 19.2R1, and all subsequent releases.
By upgrading, the hard-coded password is removed from the configuration.
This issue is being tracked as 1334365 .
Workaround:
Configure a new password for the device by referring to https://www.juniper.net
/documentation/en_US/release-independent/junos/topics/task/configuration/
nfx250-configure-vsrx-internal-ip.html .
Additionally, to reduce the risk of exploitability of this issue, customers may
choose to implement firewall filters / ACLs to limit administrative access to
the VNF vSRX instance to only trusted hosts, networks and administrators.
Disable unnecessary services not required to administer the system, until such
time that either a password change can take place, or the fixed software is
applied during a maintenance window.
Implementation:
Software release Service Packages are available at http://support.juniper.net
from the "Download Software" links.

2020-04-08: Initial publication
