CVE-2023-44016
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 · uneditedTenda AC10U v1.0 US_AC10UV1.0RTL_V15.03.06.49_multi_TDE01 was discovered to contain a stack overflow via the deviceId parameter in the addWifiMacFilter function.
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 confidenceA stack buffer overflow vulnerability exists in the Tenda AC10U v1.0 router firmware (US_AC10UV1.0RTL_V15.03.06.49). The vulnerability is located in the addWifiMacFilter function where the deviceId parameter is not properly bounds-checked before being copied to a stack-allocated buffer, allowing an attacker to overwrite return addresses and potentially execute arbitrary code.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the router modelAccess the router admin panel (typically at 192.168.0.1) or check the physical device label to confirm the model is Tenda AC10U v1.0Affected if The device is not a Tenda AC10U v1.0 router, then it is not affected by this specific CVE
-
Check the firmware versionIn the router admin panel, navigate to System Settings or Firmware Upgrade section to view the installed firmware version. The affected version is 15.03.06.49Affected if The installed firmware version is 15.03.06.49_multi_tde01, then this specific version is affected
-
Locate the WiFi MAC filter settingsIn the router admin panel, navigate to Advanced Settings or Wireless Settings and look for MAC Filter, Wireless MAC Filter, or Access Control settingsAffected if The WiFi MAC filter feature is not present or not accessible, the vulnerability cannot be triggered
-
Verify if the addWifiMacFilter function is reachableAttempt to access or configure the WiFi MAC filter feature through the web interface or API endpoint (typically under /goform/ or similar URL path)Affected if The addWifiMacFilter function is accessible and the deviceId parameter can be supplied without proper validation, the vulnerability is present and exploitable
You are affected if you have a Tenda AC10U v1.0 router running firmware version 15.03.06.49 and the WiFi MAC filter functionality is accessible in your environment.

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.
From vendor dataIf an official firmware update is available, apply it immediately. Otherwise, disable the WiFi MAC filter functionality via the router admin panel, implement network segmentation to limit exposure, and consider replacing the device with a model that receives regular security updates.
