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
Hidden functionality vulnerability in LAN-WH300N/RE all versions provided by LOGITEC CORPORATION allows an authenticated user to execute arbitrary OS commands on a certain management console.

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 confidence

Hidden functionality in the LAN-WH300N/RE management console allows authenticated users to inject and execute arbitrary operating system commands, likely through unsanitized input fields in the administrative interface.

MitigationApply available firmware updates from LOGITEC CORPORATION; if no patch exists, restrict management console access to trusted networks and consider disabling remote management features.

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 LAN-WH300N/RE devices on your network
    Scan your network for devices with MAC vendor prefix 00:1F:1F (Elecom) or identify the device model through network discovery tools, or physically inspect devices matching the LAN-WH300N/RE specification
    Affected if A device matching the Elecom LAN-WH300N/RE model is present on your network
  2. Locate the management console access point
    Check if the device management interface is accessible by attempting to reach the default IP address or scanning for HTTP/HTTPS services on common management ports (80, 443, 8080)
    Affected if The device management console is accessible over the network
  3. Verify authentication status to the management interface
    Determine if you have valid credentials for the administrative interface, or check if there are any unexpected admin accounts configured in the user management section of the console
    Affected if You have authenticated access to the management console and can observe the user account configuration
  4. Inspect administrative input fields for unexpected functionality
    Within the authenticated management console, examine input fields in administrative sections (such as network settings, diagnostics, or configuration areas) for any undocumented parameters, hidden command execution features, or unusual field behaviors
    Affected if Any administrative input field accepts or appears to process operating system commands without proper sanitization indication

You are affected if you have an Elecom LAN-WH300N/RE device with an accessible management console that accepts unauthenticated or authenticated command injection in administrative input fields.
