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
Systemic Lack of Cross-Site Request Forgery (CSRF) Token Implementation.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

BLU-IC2 and BLU-IC4 devices through version 1.19.5 lack anti-CSRF token implementation, allowing attackers to craft malicious requests that execute state-changing operations (e.g., configuration changes, credential modifications) on behalf of authenticated users without their consent.

MitigationImplement anti-CSRF tokens (synchronizer token pattern) for all state-changing operations and validate Origin/Referer headers to prevent cross-origin requests.

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 the device model
    Access the device web interface or CLI and locate the model identification (BLU-IC2 or BLU-IC4) in the system information or device status page
    Affected if The device is a BLU-IC2 or BLU-IC4 model
  2. Check the installed firmware version
    Navigate to the device's firmware or system settings page, or run the command `show version` or `device info` via CLI to retrieve the firmware version number
    Affected if The firmware version is 1.19.5 or lower (any version < 1.20)
  3. Inspect web forms for CSRF token presence
    Log into the device web interface, open the browser developer tools (Network tab), and examine state-changing forms (e.g., configuration save, user management, network settings) for a hidden input field containing a token value (commonly named 'csrf_token', 'token', 'anticsrf', or similar)
    Affected if No anti-CSRF token field is found in any state-changing form
  4. Verify token validation on form submission
    Submit a state-changing form while capturing the request in developer tools. Check if the request includes a token parameter and if removing it causes the server to reject the request
    Affected if The request succeeds without a token or the server does not validate the token

If the device is a BLU-IC2 or BLU-IC4 with firmware version below 1.20 and the web interface lacks anti-CSRF tokens in state-changing operations, the environment is affected by this CVE.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 1.20 or later
Fixed in 1.20
Interim mitigation

Implement anti-CSRF tokens (synchronizer token pattern) for all state-changing operations and validate Origin/Referer headers to prevent cross-origin requests.

Recommended fix Moderate confidence

BLU-IC2 Firmware 1.20 and BLU-IC4 Firmware 1.20

  1. Identify the current firmware version of the BLU-IC2 or BLU-IC4 device via the administrative web interface or CLI
  2. Navigate to the official vendor support site or firmware download area for BLU-IC series devices
  3. Download the firmware version 1.20 (or latest stable version) for your specific device model (BLU-IC2 or BLU-IC4)
  4. Access the device's firmware update section in the administrative interface
  5. Upload and apply the downloaded firmware file, following the vendor's instructions for the update process
  6. Allow the device to complete the firmware installation and reboot cycle
  7. After reboot, verify the new firmware version is 1.20 or later in the device interface
  8. Test the application functionality to confirm the update was successful and CSRF protection is now active
Caveat No specific breaking changes documented in the provided materials; standard firmware upgrade precautions apply (backup configuration, ensure stable power during update)
