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 weakness has been identified in Tenda BE12 Pro 16.03.66.23. This vulnerability affects the function fromSafeUrlFilter of the file /goform/SafeUrlFilter. Executing a manipulation of the argument page can lead to stack-based buffer overflow. The attack may be performed from remote. The exploit has been made available to the public and could be used for attacks.

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

Stack-based buffer overflow in Tenda BE12 Pro router firmware 16.03.66.23 within the fromSafeUrlFilter function in /goform/SafeUrlFilter. The 'page' parameter lacks proper bounds checking, allowing remote attackers to potentially overwrite stack memory and execute arbitrary code.

MitigationApply vendor firmware patch when available; if no patch exists, disable remote management interfaces, segment affected devices on isolated VLANs, and monitor for exploit attempts.

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 admin interface or check the device label to confirm the model is Tenda BE12 Pro
    Affected if Device is not a Tenda BE12 Pro router, then it is not affected by this specific CVE
  2. Check firmware version
    Log into the router admin panel and navigate to System Settings or Firmware Upgrade page to view the installed firmware version, or use the command 'cat /proc/version' if telnet/ssh access is available
    Affected if Firmware version is 16.03.66.23 exactly, as this is the specific version mentioned in the CVE
  3. Verify SafeUrlFilter endpoint exists
    Attempt to access or probe the /goform/SafeUrlFilter endpoint on the router (typically via HTTP GET or POST to the router's IP address with this path)
    Affected if The endpoint responds, indicating the vulnerable function exists on the device
  4. Confirm remote management is accessible
    Check if the router's web interface is reachable from the WAN/internet side, or check the router's firewall/remote management settings to see if external access to /goform/* endpoints is permitted
    Affected if Remote management or the web interface is exposed to WAN, allowing remote attackers to reach the vulnerable endpoint
  5. Inspect for exploitation indicators
    Review router system logs or web server logs for unusual POST requests to /goform/SafeUrlFilter with abnormally long 'page' parameter values, or check for unexpected new admin accounts or configuration changes
    Affected if Logs show suspicious requests to SafeUrlFilter or unexplained system changes

The device is affected if it is a Tenda BE12 Pro running firmware version 16.03.66.23 with the SafeUrlFilter feature accessible, particularly if remote management is enabled.
