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 was discovered to contain a stack overflow via the security_5g parameter in the function formWifiBasicSet.

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 overflow vulnerability in Tenda AC23 v16.03.07.44 in the formWifiBasicSet function via the security_5g parameter, allowing potential remote code execution or denial of service via malformed input.

MitigationUpdate router firmware to a patched version, or implement proper input validation and bounds checking on the security_5g parameter in the formWifiBasicSet function.

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 router admin panel or check device label to confirm model is Tenda AC23 or AC2100
    Affected if Device is not a Tenda AC23 or AC2100 model
  2. Check firmware version
    In router admin panel, go to System Settings or Administration > Firmware Update to view current firmware version. Alternatively, check via telnet/SSH if enabled using 'cat /proc/version' or '固件版本' command
    Affected if Firmware version is NOT exactly 16.03.07.44 (only this specific version is affected)
  3. Verify WiFi functionality is enabled
    In router admin panel, check Wireless Settings or WiFi settings page to confirm wireless is enabled
    Affected if WiFi is completely disabled (vulnerability cannot be triggered without WiFi access to formWifiBasicSet)
  4. Confirm 5G wireless band is configured
    In router admin panel wireless settings, verify 5GHz band security settings are accessible via the formWifiBasicSet function
    Affected if 5G WiFi band is not configured or not accessible

Device is affected only if it is a Tenda AC23/AC2100 router running exactly firmware version 16.03.07.44 with WiFi functionality enabled and 5G band configured.
