NFX250 Series: Hardcoded credentials in the vSRX VNF instance.

Published Apr 8, 2020 CVSS 3.1 · 10 Critical EPSS 1.4% KEV · Not listed
Description
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.

Remediation

Vendor 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.


Vendor 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.
