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 · unedited
Edimax EW-7438RPn-v3 Mini 1.27 contains a remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary commands through the /goform/mp endpoint. Attackers can exploit the vulnerability by sending crafted POST requests with command injection payloads to download and execute malicious scripts on the device.

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 confidence

The Edimax EW-7438RPn-v3 Mini firmware 1.27 has a command injection vulnerability in the /goform/mp endpoint. Unauthenticated attackers can send crafted POST requests containing shell metacharacters to inject and execute arbitrary operating system commands, allowing download and execution of malicious scripts.

MitigationApply vendor firmware update if available; otherwise, isolate the device behind a firewall with no external access or replace the end-of-life device.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Access the device web interface (typically at 192.168.x.x) and check the status or device info page, or inspect network discovery/DHCP lease for Edimax EW-7438RPn-v3
    Affected if The device is an Edimax EW-7438RPn-v3 Mini
  2. Check the firmware version
    In the device web interface, navigate to Status or System settings and locate the firmware version field
    Affected if The firmware version displayed is exactly 1.27
  3. Verify the /goform/mp endpoint exists
    Send a GET or POST request to http://[device-ip]/goform/mp using curl or a browser developer tool
    Affected if The endpoint responds (even with an error) indicating it is accessible
  4. Check management interface exposure
    Determine if the device web interface is accessible from untrusted networks (WAN) by checking router port forwards, firewall rules, or attempting external access
    Affected if The device management interface is reachable from outside the local network without firewall protection

You are affected if you have an Edimax EW-7438RPn-v3 Mini running firmware version 1.27 with the /goform/mp endpoint accessible, especially if exposed to untrusted networks.
