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
Tenda AC18 V15.03.05.19 is vulnerable to Buffer Overflow via /goform/add_white_node.

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 · moderate confidence

Buffer overflow in Tenda AC18 router firmware V15.03.05.19 in the /goform/add_white_node endpoint allows remote attackers to execute arbitrary code via crafted input. The CVSS 9.8 indicates network-exploitable, low-attack-complexity vulnerability requiring no authentication.

MitigationApply vendor firmware patch when available; until then, disable remote web management, restrict administrative interface to trusted networks, or place device behind a firewall.

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
    Locate the router model number on the device label or check the web administration interface system information page. Confirm it is a Tenda AC18 model.
    Affected if The device is a Tenda AC18 router
  2. Check the installed firmware version
    Access the router's web administration interface (typically at 192.168.0.1) and navigate to System Settings or Firmware Upgrade section to view the current firmware version. Alternatively, check the firmware file name if you have access to it.
    Affected if The firmware version is exactly 15.03.05.19
  3. Verify the web management interface is accessible
    Attempt to access the router's web interface from the network where the router is deployed. Check if HTTP/HTTPS ports 80 or 443 respond to requests.
    Affected if The router's web interface is reachable from untrusted networks (not just from trusted internal segments)
  4. Confirm the /goform/add_white_node endpoint exists
    Send an HTTP GET or POST request to http://<router-ip>/goform/add_white_node and observe the response. A valid endpoint will return a response (even if error), while a non-existent endpoint may return 404.
    Affected if The /goform/add_white_node endpoint is accessible and responds to requests

You are affected if you have a Tenda AC18 router running firmware version 15.03.05.19 with the web management interface exposed to untrusted networks, as the unauthenticated add_white_node endpoint contains the buffer overflow vulnerability.
