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 Gateway 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-18809.

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 routers allows unauthenticated network-adjacent attackers to execute arbitrary code as root. The flaw exists in the HNAP1 SOAP endpoint's SetAPLanSettings function, which fails to validate user-supplied input before using it in a system call.

MitigationApply vendor firmware patch when available; until then, restrict network access to the device's management interface and consider network segmentation to limit exposure.

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 web interface or check the device label to confirm the model is D-Link DAP-1325
    Affected if Device is not a D-Link DAP-1325
  2. Check firmware version
    Navigate to the router's web interface (typically at 192.168.0.1) and look in the Status or Firmware Upgrade section for the current firmware version, or use the command 'cat /proc/version' or 'sysinfo' via telnet/SSH if available
    Affected if Firmware version is below 1.09b03
  3. Verify HNAP1 endpoint accessibility
    Attempt to access the HNAP1 SOAP endpoint by sending an HTTP request to http://<device_ip>/HNAP1/ - the device is vulnerable only if this endpoint responds without authentication
    Affected if HNAP1 endpoint is reachable from the network without authentication
  4. Confirm SetAPLanSettings function exposure
    Send a crafted SOAP request to the HNAP1 endpoint invoking the SetAPLanSettings action (or inspect the device's SOAP action list) - if the function is exposed and the device firmware is < 1.09b03, command injection is possible
    Affected if SetAPLanSettings function is accessible and firmware version is < 1.09b03

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

Interim mitigation

Apply vendor firmware patch when available; until then, restrict network access to the device's management interface and consider network segmentation to limit exposure.

Recommended fix High confidence

DAP-1325 Firmware 1.09b03 or later

  1. Navigate to the official D-Link support page for the DAP-1325 router
  2. Locate the firmware download section for model DAP-1325
  3. Download firmware version 1.09b03 or any later stable release
  4. Access the router's web administration interface
  5. Navigate to the Administration or System Settings section
  6. Locate the Firmware Upgrade option
  7. Upload the downloaded firmware file and initiate the upgrade
  8. Wait for the upgrade to complete and the device to reboot
Caveat Firmware upgrades may reset configuration to defaults; back up current settings before upgrading if possible
