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
** UNSUPPORTED WHEN ASSIGNED ** A vulnerability classified as critical has been found in D-Link DAR-7000-40 V31R02B1413C. Affected is an unknown function of the file interface/sysmanage/licenseauthorization.php. The manipulation of the argument file_upload leads to unrestricted upload. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-264528. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: Vendor was contacted early and confirmed immediately that the product is end-of-life. It should be retired and replaced.

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 · high confidence

Unrestricted file upload vulnerability in D-Link DAR-7000-40's licenseauthorization.php script. Attackers can upload arbitrary files via the file_upload parameter, likely enabling remote code execution. The 9.8 CVSS indicates trivial exploitation with maximum impact.

MitigationProduct is end-of-life with no vendor patch available. Recommend immediate network isolation via firewall/ACLs restricting access to the admin interface, followed by retirement and migration to a supported solution.

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 check the device label/documentation to confirm it is a D-Link DAR-7000-40 device
    Affected if The device is a D-Link DAR-7000-40
  2. Check the firmware version
    Log into the device admin interface and navigate to the status or system information page to view the installed firmware version. Alternatively, check the device startup logs or firmware file metadata
    Affected if The firmware version is v31r02b1413c
  3. Verify the vulnerable script exists
    Attempt to access the licenseauthorization.php script via HTTP/HTTPS (e.g., https://<device-ip>/licenseauthorization.php)
    Affected if The script is accessible and returns a response (200 OK)
  4. Confirm file upload functionality is present
    Inspect the page source of licenseauthorization.php or check if the file_upload parameter is accepted by submitting a test request with a benign file
    Affected if The script accepts the file_upload parameter and does not reject the upload
  5. Check for unexpected uploaded files
    Inspect the web root directory on the device (if accessible via SSH/TFTP) or check the upload directory for any unexpected files that were not intentionally uploaded by administrators
    Affected if There are unexpected or unknown files in the upload directory

You are affected if you have a D-Link DAR-7000-40 device running firmware v31r02b1413c with the licenseauthorization.php script accessible on the network.

Mitigation

Product is end-of-life with no vendor patch available. Recommend immediate network isolation via firewall/ACLs restricting access to the admin interface, followed by retirement and migration to a supported solution.

Recommended fix High confidence
  1. This vulnerability affects D-Link DAR-7000-40 firmware v31r02b1413c, which is explicitly end-of-life and no longer supported by the vendor.
  2. The vendor (D-Link) has stated the product should be retired and replaced rather than patched.
  3. Replace the affected D-Link DAR-7000-40 device with a currently supported alternative solution from D-Link or another vendor.
  4. If immediate replacement is not possible, implement network segmentation to isolate the affected device and restrict access to the management interface from untrusted networks.
  5. Disable the interface/sysmanage/licenseauthorization.php functionality if possible through network access controls.
  6. Monitor for any Indicators of Compromise and implement additional logging on the device.
Caveat This product is end-of-life with no security updates available; replacement is the only remediation path.
