Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Missing Initial Password Change.This issue affects BLU-IC2: through 1.19.5; BLU-IC4: through 1.19.5.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The BLU-IC2 and BLU-IC4 devices ship with a missing initial password change requirement, allowing unauthenticated attackers to access the device with default or no credentials. This is a critical authentication bypass vulnerability in embedded industrial control devices.

MitigationEnforce mandatory password change on first boot or first login, and consider shipping devices with unique randomly-generated default credentials.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify device model and firmware version
    Access the device management interface, system information page, or use the device's CLI/API to retrieve the firmware version. Look for 'Azure Access Blu Ic2' or 'Azure Access Blu Ic4' model identification and note the installed firmware version number.
    Affected if The device is a BLU-IC2 or BLU-IC4 model running firmware version 1.20 or lower.
  2. Verify if default credentials are active
    Attempt to log in to the device using commonly known default credential pairs (such as admin/admin, admin/password, root/root, or no password) or check the authentication configuration for evidence that default credentials have not been changed.
    Affected if Default credentials (such as admin/admin, admin/password, or an empty password) successfully authenticate or the system accepts login without a password change prompt.
  3. Check password change enforcement status
    Review the device's security settings, user account policies, or authentication logs to determine whether the system enforces a mandatory password change on first boot or first login. Look for a 'password change required' flag, 'first login' state, or similar configuration indicator.
    Affected if The device allows full access without requiring the user to change from a default or blank password, indicating the password change requirement is not enforced.
  4. Confirm device is accessible without prior authentication
    Attempt to access device administrative interfaces, APIs, or network services (such as web management ports, telnet, SSH, or REST endpoints) without providing any credentials to see if access is granted.
    Affected if Unauthenticated access is granted to administrative functions, APIs, or control interfaces without being prompted to set or change a password first.

The environment is affected if the device is an Azure Access Blu Ic2 or Blu Ic4 running firmware version below 1.20 and the system allows access with default credentials or without enforcing an initial password change.
