NVD · unedited
D-Link DAP-1325 HNAP SetHostIPv6Settings IPv6Mode 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-18815.

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

The D-Link DAP-1325 router contains a command injection vulnerability in its HNAP1 SOAP endpoint's SetHostIPv6Settings function. The vulnerability stems from insufficient validation of user-supplied input before passing it to a system call, allowing unauthenticated attackers to execute arbitrary code with root privileges.

MitigationApply available firmware updates from D-Link; if no patch exists, implement network segmentation to restrict access to the device or replace the affected hardware.

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 device model
    Access the router's web interface or check the device label to confirm it is a D-Link DAP-1325
    Affected if The device is not a D-Link DAP-1325, this specific CVE does not apply
  2. Check the firmware version
    Log into the router web interface and navigate to Status or Management page to view the firmware version, or use the command: `grep Version /etc/os-release` or check the file system if you have telnet/SSH access
    Affected if Firmware version is less than 1.09b03 (e.g., 1.08, 1.07, etc.)
  3. Verify HNAP1 SOAP endpoint accessibility
    Attempt to access the HNAP1 endpoint via HTTP at the router's IP address (typically http://<router-ip>/HNAP1/)
    Affected if The HNAP1 SOAP endpoint is reachable from the network where the attacker is located
  4. Confirm SetHostIPv6Settings function exposure
    Send a SOAP request to the HNAP1 endpoint with the SetHostIPv6Settings action to test if the function is exposed and accepts input
    Affected if The SetHostIPv6Settings function is accessible and processes input without proper sanitization

The device is affected if it is a D-Link DAP-1325 running firmware version below 1.09b03 and the HNAP1 SOAP endpoint with SetHostIPv6Settings is accessible from the network.

Upgrade available Upgrade to 1.09b03 or later
Fixed in 1.09b03
Interim mitigation

Apply available firmware updates from D-Link; if no patch exists, implement network segmentation to restrict access to the device or replace the affected hardware.

Recommended fix High confidence

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

  1. 1. Check the current firmware version of the D-Link DAP-1325 router via the web management interface (usually at http://192.168.0.1)
  2. 2. Navigate to the Administration or System Settings section to view firmware version
  3. 3. If the firmware version is below 1.09b03, download the latest firmware (1.09b03 or later) from D-Link's official support website (supportannouncement.us.dlink.com)
  4. 4. In the router's web interface, go to the Firmware Upgrade section
  5. 5. Upload the downloaded firmware file and apply the update
  6. 6. Wait for the router to reboot and verify the new firmware version is installed
Caveat Ensure stable power during firmware upgrade to avoid rendering the device inoperable
