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, which was classified as critical, has been found in D-Link DAR-7000-40 V31R02B1413C. Affected by this issue is some unknown functionality of the file /useratte/resmanage.php. The manipulation of the argument file leads to unrestricted upload. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. VDB-264530 is the identifier assigned to this vulnerability. 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

A critical unrestricted file upload vulnerability exists in D-Link DAR-7000-40 (V31R02B1413C) at /useratte/resmanage.php. The 'file' parameter is not properly validated, allowing remote attackers to upload arbitrary files including malicious scripts. This vulnerability has a public exploit and CVSS 9.8 score.

MitigationSince the product is end-of-life with no vendor support, retire and replace the D-Link DAR-7000-40 with a currently supported solution. If immediate mitigation is required, restrict network access to the management interface via ACLs or firewall rules.

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's web management interface or check the physical device label to confirm it is a D-Link DAR-7000-40 device.
    Affected if The device is NOT a D-Link DAR-7000-40 model.
  2. Check the firmware version
    Log into the device administration panel or use the command line interface (if accessible) to retrieve the installed firmware version. Look for version information in the system status or About section.
    Affected if The installed firmware version is v31r02b1413c.
  3. Verify management interface accessibility
    Attempt to access the URI /useratte/resmanage.php over HTTP/HTTPS from a network perspective to confirm the endpoint is reachable. This may require authentication depending on the device configuration.
    Affected if The /useratte/resmanage.php endpoint is accessible from the network.
  4. Look for unexpected uploaded files
    If you have administrative access, examine the web root directory and any directories associated with /useratte/resmanage.php for unfamiliar files, especially PHP scripts, JSP files, or executables that were not intentionally deployed.
    Affected if Unexpected script or executable files are found on the device.

You are affected if you are running D-Link DAR-7000-40 firmware version v31r02b1413c AND the management interface with the vulnerable /useratte/resmanage.php endpoint is network-accessible.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Since the product is end-of-life with no vendor support, retire and replace the D-Link DAR-7000-40 with a currently supported solution. If immediate mitigation is required, restrict network access to the management interface via ACLs or firewall rules.

Recommended fix High confidence

Product is end-of-life - no upgrade path available. Replace with a currently supported device.

  1. This vulnerability affects D-Link DAR-7000-40 firmware v31r02b1413c which is end-of-life and no longer supported by the vendor.
  2. The official guidance from D-Link states this product should be retired and replaced.
  3. No patch or firmware update is available for this vulnerability.
  4. Replace the affected D-Link DAR-7000-40 device with a currently supported security solution from D-Link or an alternative vendor.
  5. If immediate replacement is not possible, restrict network access to the /useratte/resmanage.php endpoint using firewall rules or ACLs to prevent unauthorized access.
  6. Monitor the device for any signs of compromise since this is a publicly disclosed exploit.
Caveat This is an end-of-life product with no security updates. Continuing use poses significant security risk.
