Evidence used

  • No CISA KEV confirmation is currently recorded.
  • A structured source references public exploit or proof-of-concept material.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 0.49% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs netbox-community netbox-docker and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

What, why and how

netbox-docker before 2.5.0 has a superuser account with default credentials (admin password for the admin account, and 0123456789abcdef0123456789abcdef01234567 value for SUPERUSER_API_TOKEN). In practice on the public Internet, almost all users changed the password but only about 90% changed the token. Having a default token value was intentional and was valuable for the main intended use case of the netbox-docker product (isolated development networks). Some users engaged in an effort to repurpose netbox-docker for production. The documentation for this effort stated that the defaults must not be used. However, installation did not ensure non-default values. The Supplier was aware of the CVE ID assignment and did not object to the assignment.

However, installation did not ensure non-default values. The Supplier was aware of the CVE ID assignment and did not object to the assignment.

Why

The product uses default credentials (such as passwords or cryptographic keys) for potentially critical functionality.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.

Likely attack path

CWE-1392: Use of Default Credentials. The product uses default credentials (such as passwords or cryptographic keys) for potentially critical functionality.

Official advisory ↗
JVN iPedia · Japanese · JVNDB-2026-014888NetBox LabsのNetbox-dockerにおける複数の脆弱性

netbox-docker 2.5.0以前のバージョンには、デフォルトの資格情報を持つスーパーユーザーアカウントが存在していました（管理者アカウントのadminパスワードおよびSUPERUSER_API_TOKENは0123456789abcdef0123456789abcdef01234567という値でした）。実際には、ほとんどのユーザーがパスワードを変更しましたが、トークンを変更したのは約90%のユーザーのみでした。デフォルトのトークン値を設定することは意図的であり、netbox-docker製品の主要な使用ケースである隔離された開発ネットワークに対して有用でした。一部のユーザーはnetbox-dockerを本番環境で再利用しようと試みました。この試みに関する文書には、デフォルトの値を使用してはならないと明記されていました。しかし、インストール時にはデフォルトでない値の設定が保証されていませんでした。供給者はCVE IDの割り当てを認識しており、割り当てに異議を唱えませんでした。
