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 has been found in D-Link DAR-7000 up to 20151231 and classified as critical. Affected by this vulnerability is an unknown functionality of the file /sysmanage/licence.php. The manipulation of the argument file_upload leads to unrestricted upload. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-240241 was 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

Unrestricted file upload vulnerability in D-Link DAR-7000 (end-of-life) allows remote attackers to upload arbitrary files via the file_upload parameter in /sysmanage/licence.php, potentially leading to remote code execution.

MitigationSince the product is end-of-life and unsupported, the official guidance is to retire and replace the device. If continued use is unavoidable, consider network isolation and disable the affected service, but replacement is strongly recommended.

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 D-Link device model
    Access the device administrative interface or check the physical device label to confirm the model is a DAR-7000 or DAR-8000 series device.
    Affected if The device is a D-Link DAR-7000 or DAR-8000.
  2. Check the firmware version
    Locate the firmware version in the device administrative interface (typically under System, Status, or About sections) or via CLI if accessible. Compare the version date or number against 20151231.
    Affected if The firmware version date is 20151231 or earlier.
  3. Verify the /sysmanage/licence.php endpoint is accessible
    Attempt to access https://<device-ip>/sysmanage/licence.php from a system that can reach the device. A successful HTTP response (even an error page) indicates the endpoint exists.
    Affected if The endpoint returns an HTTP response rather than a connection failure.
  4. Confirm management interface is network-exposed
    Determine if the device management interface (typically ports 80, 443, or custom admin ports) is accessible from network segments beyond the intended administrative zone.
    Affected if The management interface is reachable from networks other than a dedicated admin VLAN.

The environment is affected if the device is a D-Link DAR-7000 or DAR-8000 running firmware dated 20151231 or earlier, with the management interface network-accessible.

Interim mitigation

Since the product is end-of-life and unsupported, the official guidance is to retire and replace the device. If continued use is unavoidable, consider network isolation and disable the affected service, but replacement is strongly recommended.

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 official description explicitly states: 'It should be retired and replaced.'
  3. Replace the affected D-Link DAR-7000/DAR-8000 devices with a currently supported alternative product.
  4. If replacement is not immediately possible, implement network segmentation to isolate these devices and restrict access to the /sysmanage/licence.php endpoint using firewall rules or ACLs.
  5. Monitor for any unauthorized file uploads or suspicious activity on these devices.
Caveat Product is end-of-life with no firmware updates; device must be replaced with a supported alternative
