CVE-2026-9344
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 vulnerability has been detected in Edimax EW-7438RPn up to 1.31. The impacted element is an unknown function of the file /goform/formWpsStart of the component webs. Such manipulation of the argument pinCode/wlan-url leads to stack-based buffer overflow. The attack can be executed remotely. The exploit has been disclosed publicly and may be used. 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 confidenceStack-based buffer overflow in Edimax EW-7438RPn wireless range extender web interface (firmware up to v1.31). The /goform/formWpsStart handler fails to properly validate input length for pinCode/wlan-url parameters before copying to stack buffers, allowing remote attackers to overflow 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.
-
Confirm device modelAccess the device web interface or check the device label/menu for model number EW-7438RPnAffected if Device is not an Edimax EW-7438RPn model, then it is not affected by this specific CVE
-
Identify firmware versionLog into the device web interface and navigate to System Settings or Status page to find the firmware version numberAffected if Firmware version is unknown or falls within the vulnerable version range for this model
-
Verify web interface accessibilityAttempt to access the device login page at the default IP (typically 192.168.1.1) via HTTPAffected if Web interface is not accessible from your network segment, reducing exposure
-
Check WPS statusIn the device web interface, locate WPS settings (usually under Wireless or WPS configuration) and determine if WPS is enabledAffected if WPS is enabled and the device is a vulnerable EW-7438RPn firmware version, making exploitation possible
-
Test vulnerable endpoint presenceSend a request to /goform/formWpsStart on the device and observe if the endpoint respondsAffected if The endpoint responds and WPS is enabled on a vulnerable firmware version
Your environment is affected if you have an Edimax EW-7438RPn device running a vulnerable firmware version with the web interface accessible and WPS functionality enabled.

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 dataSince the vendor did not respond and no patch is available, mitigate by disabling remote web management access, placing the device behind a restrictive firewall, and considering device replacement if network isolation is not feasible.
