CVE-2023-44013
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 list parameter in the fromSetIpMacBind 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 · high confidenceA stack buffer overflow vulnerability exists in the Tenda AC10U v1.0 router firmware (US_AC10UV1.0RTL_V15.03.06.49_multi_TDE01) within the fromSetIpMacBind function. The 'list' parameter received by this function is not properly bounds-checked before being copied to a fixed-size stack 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 device model and firmware versionAccess the router web interface (typically at 192.168.0.1) and navigate to System Settings > Firmware Version, or log in via SSH/Telnet and run 'cat /proc/version' or check '/etc/version'. Look for the exact firmware build string.Affected if The firmware version is exactly US_AC10UV1.0RTL_V15.03.06.49_multi_TDE01 or contains the version string 15.03.06.49_multi_tde01.
-
Verify the vulnerable binary contains the functionExtract the firmware (if accessible) or check the httpd binary on the device. On the device, run 'strings /bin/httpd | grep fromSetIpMacBind' or use binwalk to extract the firmware and search for the function name.Affected if The binary contains the 'fromSetIpMacBind' function, indicating the vulnerable code path exists.
-
Confirm IP-MAC binding feature is exposedAccess the router web interface and check if there is an IP-MAC binding page (usually under Advanced > IP-MAC Binding or similar). Alternatively, send a POST request to /goform/SetIpMacBind with a test 'list' parameter.Affected if The IP-MAC binding feature is enabled or accessible on the device.
-
Check for signs of exploitationReview router logs for unusual activity around the SetIpMacBind endpoint. On the device, run 'cat /var/log/messages' or check for unexpected processes or network connections.Affected if Logs show repeated or large 'list' parameter submissions to the SetIpMacBind endpoint, or unexpected remote connections.
A user is affected if they are running Tenda AC10U v1.0 firmware version 15.03.06.49_multi_tde01 and the IP-MAC binding feature is accessible on their device.

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 dataApply vendor firmware updates if available; otherwise, restrict administrative interface access to trusted networks only, disable the IP-MAC binding feature if not required, and consider replacing the end-of-life device with a supported model.
