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 AC23 v16.03.07.44 is vulnerable to Stack Overflow that will allow for the execution of arbitrary code (remote).

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

A stack-based buffer overflow vulnerability in Tenda AC23 router firmware v16.03.07.44 allows remote attackers to execute arbitrary code by overflowing a stack buffer, likely through an improperly validated input field in the web interface or API.

MitigationApply vendor firmware patch when available; until then, restrict network access to the router's management interface and disable remote administration if possible.

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 router model
    Log into the router admin panel or check the device label to confirm the model is Tenda AC23 (AC2100)
    Affected if Device is not a Tenda AC23 AC2100 model
  2. Check firmware version
    Access router admin panel (typically 192.168.0.1), navigate to System Settings or Firmware Upgrade section to view current firmware version
    Affected if Firmware version is exactly 16.03.07.44
  3. Verify web interface accessibility
    Attempt to access the router web management interface from the network using the router IP address
    Affected if Web interface is accessible on the network
  4. Check remote administration status
    In router admin panel, locate Remote Management or Remote Administration settings (usually under Advanced or Security settings)
    Affected if Remote administration is enabled allowing access from WAN

Affected only if the device is a Tenda AC23 AC2100 router running firmware version 16.03.07.44 AND the web interface is network-accessible (especially from WAN).
