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
D-Link DIR-1260 Wi-Fi router firmware versions up to and including v1.20B05 contain a command injection vulnerability within the web management interface that allows for unauthenticated attackers to execute arbitrary commands on the device with root privileges. The flaw specifically exists within the SetDest/Dest/Target arguments to the GetDeviceSettings form. The management interface is accessible over HTTP and HTTPS on the local and Wi-Fi networks and optionally from the Internet.

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

D-Link DIR-1260 router firmware up to v1.20B05 contains an unauthenticated command injection vulnerability in the web management interface. Attackers can inject arbitrary OS commands through the SetDest/Dest/Target parameters in the GetDeviceSettings form, achieving root-level code execution.

MitigationUpdate router firmware to a patched version once available; until then, disable remote management access and restrict the web interface to trusted networks only.

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. Confirm device model
    Identify the router model in your environment. This vulnerability affects only the D-Link DIR-1260 model. Check device labels, management interface, or network inventory for the exact model number.
    Affected if The device is a D-Link DIR-1260 router.
  2. Check firmware version
    Access the router web management interface and navigate to the firmware/version information page, or use the router's status or system information section to identify the installed firmware version.
    Affected if The firmware version is 1.20B05 or any version lower than 1.20B05 (the CVE specifies <= 1.20b05 as affected).
  3. Verify web management interface accessibility
    Determine if the router's web management interface is reachable from network locations where untrusted users could originate requests. Check router settings for remote management enable status and any IP access restrictions.
    Affected if The web management interface is exposed and accessible to untrusted networks or IP addresses.
  4. Confirm vulnerable endpoint availability
    The vulnerability resides in the GetDeviceSettings form processing functionality with SetDest, Dest, or Target parameters. Determine if this web interface functionality is operational (the vulnerability is present by default in affected versions).
    Affected if The router web management interface is functional and running an affected firmware version.

Your environment is affected if you have a D-Link DIR-1260 device running firmware version 1.20B05 or lower, with the web management interface accessible to potential attackers.

dbcve · scoped
Upgrade available Upgrade to a release after 1.20b05
Interim mitigation

Update router firmware to a patched version once available; until then, disable remote management access and restrict the web interface to trusted networks only.

Recommended fix Moderate confidence

D-Link DIR-1260 firmware version higher than 1.20B05 (check official D-Link support for latest available version)

  1. 1. Identify the current firmware version of the D-Link DIR-1260 router by logging into the web management interface and checking the firmware version in the status or settings page.
  2. 2. Navigate to the official D-Link support website (support.dlink.com) and search for the DIR-1260 product page.
  3. 3. Locate and download the latest available firmware version for the DIR-1260 router.
  4. 4. Access the router's web management interface and navigate to the firmware upgrade section (typically under Administration > Firmware Upgrade or System > Firmware).
  5. 5. Upload the downloaded firmware file and initiate the upgrade process. Do not power off the router during the upgrade.
  6. 6. After the upgrade completes, verify the new firmware version in the router's status page.
  7. 7. If a firmware version higher than 1.20B05 is not available from D-Link, consider replacing the device with a newer model that receives active security support.
