CVE-2026-9295
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 · uneditedA security flaw has been discovered in Edimax BR-6428NS 1.10. This affects the function formWirelessTbl of the file /goform/formWirelessTbl of the component POST Request Handler. Performing a manipulation of the argument vapurl results in buffer overflow. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceBuffer overflow vulnerability in Edimax BR-6428NS v1.10 router's web interface POST handler. The formWirelessTbl function in /goform/formWirelessTbl fails to properly validate the vapurl parameter length before copying it to a fixed-size buffer, allowing remote attackers to overflow the buffer and potentially execute arbitrary code via crafted HTTP POST requests.

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.
-
Confirm device model is Edimax BR-6428NSCheck the router label or log into the web admin interface and look for the model number in the status or system information pageAffected if The device is NOT an Edimax BR-6428NS router - you are not affected
-
Identify the installed firmware versionLog into the router web interface and navigate to Status or System > Firmware Version to view the running firmwareAffected if The firmware version is 1.10 (the affected version) or if you are unable to determine the version and the device is a BR-6428NS, treat as potentially affected
-
Verify the web management interface is accessibleAttempt to access the router at its local IP address (typically 192.168.2.1) via HTTP on port 80Affected if The web interface is NOT accessible - the vulnerable POST handler cannot be reached from your current network position
-
Confirm the vulnerable endpoint existsSend a POST request to http://[router-ip]/goform/formWirelessTbl with a minimal payload or check if the URL returns a response (authentication may be required)Affected if The /goform/formWirelessTbl endpoint does not exist or is not reachable - the specific vulnerable path is not present
-
Check if the administrative interface is network-exposedDetermine if the router web interface is accessible from untrusted networks (internet-facing WAN IP, port forwarded, or DMZ)Affected if The admin interface is ONLY accessible from a trusted LAN - the attack surface is reduced though the vulnerability still exists in firmware
You are affected if you own an Edimax BR-6428NS router running firmware version 1.10 with its web administrative interface accessible to the network where an attacker could send a crafted POST request to /goform/formWirelessTbl with an oversized vapurl parameter.

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 available, apply vendor firmware update; otherwise, disable or restrict access to the router's web management interface from untrusted networks, or consider replacing the end-of-life device.
