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 and DAR-8000 up to 20151231. Affected is an unknown function of the file /useratte/web.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. VDB-240246 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.

How this class of weakness works · CWE-434

The application accepts uploaded files without properly checking their type or content, so an attacker can upload something executable. If it lands where the server will run it, that is remote code execution. Remediating it means validating content rather than just the extension, storing uploads outside the web root, and never executing them.

Upgrade available Upgrade to a release after 2015-12-31
Recommended fix High confidence
  1. This vulnerability affects D-Link DAR-7000 and DAR-8000 devices which are END-OF-LIFE and no longer supported by the vendor.
  2. The vendor has explicitly stated the product should be retired and replaced. There is no patch or firmware update available.
  3. If you currently use these devices, replace them with a currently supported product from D-Link's current lineup or an alternative vendor.
  4. If replacement is not immediately possible, place these devices behind a properly configured firewall with no direct internet exposure, and restrict management access to a dedicated management VLAN only.
  5. Document the risk acceptance if operating EOL equipment is unavoidable, and plan for expedited replacement.
Caveat The affected products are end-of-life with no available updates - replacement is required rather than upgrade
