NVD · unedited
D-Link DAP-1325 HNAP SetAPLanSettings SubnetMask 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-18814.

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 command injection vulnerability exists in the HNAP1 SOAP endpoint of D-Link DAP-1325 routers. The SetAPLanSettings function fails to validate user-supplied input before using it in a system call, allowing unauthenticated network-adjacent attackers to execute arbitrary code with root privileges.

MitigationIf available, apply vendor firmware updates. Otherwise, disable HNAP functionality if possible, restrict network access to the device, or consider replacing the end-of-life device.

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 is D-Link DAP-1325
    Access the router web interface or check the device label/marketing materials to verify the exact model number
    Affected if Device is not a D-Link DAP-1325
  2. Identify the installed firmware version
    Log into the router web interface and navigate to the Status or Management page to find the firmware version, or use the router's administration CLI if available
    Affected if Firmware version is 1.09b03 or lower, or the version cannot be determined
  3. Verify HNAP1 SOAP service is accessible
    Attempt to access the HNAP1 endpoint (typically at http://<router-ip>/HNAP1/) using a web browser or curl request from a network-adjacent host
    Affected if The HNAP1 endpoint responds with a SOAP interface (returns XML containing HNAP1-related content)
  4. Confirm SetAPLanSettings function is exposed
    Send a SOAP request to the HNAP1 endpoint invoking the SetAPLanSettings action, using curl or similar tool: curl -X POST http://<router-ip>/HNAP1/ -H 'SOAPAction: "http://purenetworks.com/HNAP1/SetAPLanSettings"'
    Affected if The device returns a valid SOAP response (even if it returns an error, the function exists and is callable)

You are affected if the device is a D-Link DAP-1325 running firmware version 1.09b03 or lower AND the HNAP1 service is network-accessible with the SetAPLanSettings function exposed.

If available, apply vendor firmware updates. Otherwise, disable HNAP functionality if possible, restrict network access to the device, or consider replacing the end-of-life device.

Recommended fix Moderate confidence

D-Link DAP-1325 Firmware version 1.09b03 or later

  1. 1. Download the latest firmware version (1.09b03 or later) from the official D-Link support website at supportannouncement.us.dlink.com
  2. 2. Access the DAP-1325 router web management interface through a browser on a computer connected to the router
  3. 3. Navigate to the Administration or Settings section of the web interface
  4. 4. Locate the Firmware Upgrade option
  5. 5. Upload the downloaded firmware file and initiate the upgrade process
  6. 6. Wait for the upgrade to complete and the device to reboot automatically
  7. 7. Verify the firmware version in the router's web interface to confirm the upgrade was successful
