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 DAP-1325 HNAP SetAPLanSettings PrimaryDNS Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-1325 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of a request parameter provided to the HNAP1 SOAP endpoint. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-18812.

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

Command injection vulnerability in D-Link DAP-1325 router's HNAP1 SOAP endpoint. The SetAPLanSettings function fails to validate user-supplied input (PrimaryDNS parameter) before using it in a system call, allowing unauthenticated network-adjacent attackers to execute arbitrary code with root privileges.

MitigationThis is an end-of-life router with no available patch; replace with a currently supported device and restrict network access to management interfaces.

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 device model
    Access the router's web interface or check the device label to confirm it is a D-Link DAP-1325 router
    Affected if The device is not a D-Link DAP-1325 model
  2. Check firmware version
    Log into the router web interface and navigate to the Status or Management page to view the firmware version, or use the command 'grep -i version /proc/mtd' or check the firmware file if you have access to the device via telnet/SSH
    Affected if The installed firmware version is lower than 1.09b03 (e.g., 1.08, 1.07, etc.)
  3. Verify HNAP1 endpoint accessibility
    Attempt to access the HNAP1 SOAP endpoint by sending an HTTP request to http://[router-ip]/HNAP1/ or check if port 80 or 443 is open and responding
    Affected if The HNAP1 SOAP endpoint is reachable from the network (unauthenticated or authenticated)
  4. Confirm PrimaryDNS parameter handling
    If you have access to the router, inspect the SetAPLanSettings function in the firmware binary or capture a network request to the HNAP1 endpoint to observe how the PrimaryDNS parameter is processed
    Affected if The PrimaryDNS parameter in SetAPLanSettings is passed to a system call without sanitization (requires binary analysis or source code access to confirm)

You are affected if you own a D-Link DAP-1325 router running firmware version lower than 1.09b03 and the HNAP1 management interface is accessible on your network.

Upgrade available Upgrade to 1.09b03 or later

Interim mitigation

This is an end-of-life router with no available patch; replace with a currently supported device and restrict network access to management interfaces.

Recommended fix Moderate confidence

Firmware version 1.09b03 or later

  1. 1. Check the current firmware version of the DAP-1325 device through the router's web interface under the 'Status' or 'Management' section
  2. 2. Navigate to D-Link's official support page for the DAP-1325 at support.dlink.com
  3. 3. Download the firmware version 1.09b03 or later from the official download section
  4. 4. Access the router's web interface and go to the 'Management' or 'System' settings
  5. 5. Locate the 'Firmware Upgrade' or 'Update Firmware' option
  6. 6. Upload the downloaded firmware file and initiate the upgrade
  7. 7. Wait for the upgrade to complete (do not power off the device during this process)
  8. 8. After reboot, verify the firmware version has been updated to 1.09b03 or later
Caveat Firmware upgrades carry a small risk of device bricking if interrupted; backup router configuration before upgrading if possible
