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
A vulnerability was found in Edimax BR-6478AC 1.23. Impacted is the function formUSBFolder of the file /goform/formUSBFolder of the component POST Request Handler. The manipulation of the argument ShareName/SelectName results in buffer overflow. The attack can be executed remotely. The exploit has been made public and could be used.

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

A buffer overflow vulnerability in the Edimax BR-6478AC router firmware version 1.23 allows remote attackers to overflow buffers via the ShareName and SelectName parameters in POST requests to the /goform/formUSBFolder endpoint. The formUSBFolder function in the POST Request Handler does not properly validate input length before copying to fixed-size buffers.

MitigationIf a vendor firmware update is available, apply it immediately. Otherwise, disable the USB folder sharing feature if not required, and restrict access to the router's web management interface to trusted IP addresses or VPN-only access to reduce attack surface.

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 router web interface or check the device label/marketing to confirm it is an Edimax BR-6478AC
    Affected if The device is an Edimax BR-6478AC router
  2. Check the firmware version
    Log into the router admin panel and navigate to System Status or Firmware Upgrade page to view the installed firmware version. Alternatively, check via CLI if telnet/ssh is enabled.
    Affected if The firmware version is 1.23
  3. Verify USB storage feature is configured
    Check if the router has USB storage functionality enabled in the web interface under USB Settings, USB Share, or similar menu
    Affected if USB storage sharing is enabled and a USB device is connected
  4. Confirm the vulnerable endpoint is accessible
    Attempt to access or send a POST request to /goform/formUSBFolder endpoint from the local network
    Affected if The endpoint responds and accepts requests (indicates the USB share feature is active)

If you have an Edimax BR-6478AC router running firmware version 1.23 with USB storage sharing enabled and the formUSBFolder endpoint is accessible, your environment is affected by this vulnerability.
