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
A flaw has been found in Tenda BE12 Pro 16.03.66.23. The affected element is the function fromDhcpListClient of the file /goform/DhcpListClient. This manipulation of the argument page causes stack-based buffer overflow. The attack can be initiated remotely. The exploit has been published and may be used.

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

Stack-based buffer overflow in the DHCP client list handler of Tenda BE12 Pro routers (firmware 16.03.66.23). The fromDhcpListClient function in /goform/DhcpListClient does not properly validate the 'page' parameter before copying it to a stack buffer, allowing remote attackers to potentially execute arbitrary code via crafted HTTP requests.

MitigationIsolate the router's management interface from untrusted networks immediately. Contact Tenda for an official firmware patch. If no patch is available, implement compensating controls such as firewall rules restricting access to the web interface.

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 Tenda BE12 Pro router model
    Check the router label or web interface for the exact model number (BE12 Pro)
    Affected if Device is not a Tenda BE12 Pro router - different models have different vulnerabilities
  2. Check firmware version
    Log into the router web interface, look for firmware version in System Settings or Status page, or query the device via SNMP or telnet if available
    Affected if Firmware version is 16.03.66.23 - this is the specific version listed as vulnerable
  3. Verify DhcpListClient endpoint exists
    Send an HTTP GET request to http://[router-ip]/goform/DhcpListClient and check for a response
    Affected if The endpoint responds - indicates the vulnerable function is present on the device
  4. Confirm 'page' parameter is accepted
    Send a crafted HTTP POST or GET request to /goform/DhcpListClient with a 'page' parameter (e.g., page=test) and observe if the parameter is processed without validation
    Affected if The 'page' parameter is accepted and reflected in the response without input validation - indicates the vulnerability is present
  5. Check network exposure of management interface
    Determine if the router's web interface (port 80/443) is exposed to untrusted networks by reviewing firewall rules or performing a port scan from an external IP
    Affected if The management interface is directly accessible from untrusted networks (WAN) rather than only from trusted LAN segments

The device is affected if it is a Tenda BE12 Pro router running firmware version 16.03.66.23 with the /goform/DhcpListClient endpoint accessible and the 'page' parameter accepting unvalidated input.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation

Isolate the router's management interface from untrusted networks immediately. Contact Tenda for an official firmware patch. If no patch is available, implement compensating controls such as firewall rules restricting access to the web interface.
