CVE-2026-9362
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 1.12. This vulnerability affects the function formConnectionSetting of the file /goform/formConnectionSetting of the component Setting Handler. Such manipulation of the argument max_Conn/timeOut leads to command injection. The attack may be launched 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 confidenceCommand injection vulnerability in Edimax EW-7438RPn v1.12 WiFi range extender's web interface (/goform/formConnectionSetting). The formConnectionSetting function improperly sanitizes the max_Conn and timeOut parameters, allowing remote attackers to inject and execute arbitrary OS commands via the Setting Handler component.

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 device modelAccess the device web interface or check network discovery for Edimax EW-7438RPn. The device MAC address typically starts with 00:1F:1F or 00:1F:9F (Edimax OUI). The model is usually displayed on the status page of the web management interface.Affected if The device is an Edimax EW-7438RPn wireless range extender.
-
Check the firmware versionLog into the device web interface and navigate to System Settings or Firmware Upgrade page to view the current firmware version. Alternatively, check via SNMP if enabled, or inspect HTTP responses from the device.Affected if The firmware version is 1.12.
-
Confirm web management interface is enabledAttempt to access the device HTTP interface on port 80 or 443 from the network. Check if the login page at /login.asp or /index.asp responds.Affected if The web management interface is accessible from the network (the vulnerability requires this to be enabled).
The device is affected if it is an Edimax EW-7438RPn running firmware version 1.12 with the web management interface enabled and reachable on the network.

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 restricting network access to the device's management interface (disable remote management, place behind firewall/VPN), or replace the device with a supported model.
