CVE-2020-1614: NFX250 Series: Hardcoded credentials in the vSRX VNF instance.

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.

Security readout for executives and security teams

Plain-English summary

Juniper NFX250 systems running the vSRX VNF could expose a built-in credential path when the vSRX root password was never configured. If an attacker can reach an administrative service such as SSH, they may take control of that vSRX instance. The source states no other products or platforms are affected.

Executive priority

Treat as urgent for any NFX250 environment using vSRX VNF because compromise can grant full control of the security function. Prioritize internet- or broadly reachable management interfaces first.

Technical view

CVE-2020-1614 is CWE-798 hard-coded credentials in the NFX250 Series vSRX VNF instance. It affects versions before 19.2R1 and only applies when the vSRX VNF root password has not been configured. CVSS 3.1 is 10.0 with network attack vector, no privileges, no user interaction, and full CIA impact.

Likely exposure

Exposure is likely limited to organizations using Juniper NFX250 with the vSRX VNF on versions before 19.2R1, where root password setup was skipped and administrative services are reachable locally or over the network.

Exploitation context

The bundle does not cite active exploitation, and KEV is false. Abuse requires access to an administrative service on the vSRX VNF. The risk is highest where SSH or similar management access is reachable beyond tightly controlled management networks.

Researcher notes

Scope is narrow but impact is severe. Do not rely on generic Juniper CPE matching alone; the bundle names only NFX250 vSRX VNF before 19.2R1 with an unset root password.

Mitigation direction

  • Upgrade affected NFX250 vSRX VNF instances to 19.2R1 or later.
  • Configure the vSRX VNF root password if it is unset.
  • Restrict administrative services to trusted management networks only.
  • Review Juniper advisory JSA10997 for product-specific guidance.
  • Confirm no non-NFX250 platforms are included in remediation scope.

Validation and detection

  • Inventory NFX250 devices and identify deployed vSRX VNF versions.
  • Verify whether each vSRX VNF root password is configured.
  • Check whether SSH or other administrative services are network-accessible.
  • Review administrative login logs for unexpected access.
  • Validate remediation against Juniper advisory JSA10997.

Use of Hard-coded Credentials

Use of Hard-coded Credentials represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
