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
OS command injection vulnerability exists in ELECOM wireless LAN routers. A specially crafted request may be sent to the affected product by a logged-in user with an administrative privilege to execute an arbitrary OS command.

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

Authenticated OS command injection vulnerability in ELECOM wireless LAN routers allows a logged-in administrative user to execute arbitrary OS commands via specially crafted HTTP requests. The attacker must have valid admin credentials to exploit this issue.

MitigationUpdate to the latest ELECOM router firmware that addresses this vulnerability. Until then, restrict administrative access to trusted networks only and monitor for suspicious requests.

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 ELECOM router model and firmware version
    Log into the router's administrative web interface and navigate to the System or Status page to view the current firmware version. Note the exact model number and firmware revision.
    Affected if The installed firmware version is older than the patched version and the device is an ELECOM wireless LAN router.
  2. Verify administrative interface exposure
    Check if the router's admin web interface (typically ports 80/443) is accessible from untrusted networks by reviewing firewall rules or attempting external access from a non-local IP.
    Affected if The administrative interface is exposed to the internet or untrusted networks, increasing the attack surface.
  3. Review user accounts for unauthorized changes
    Access the router's user management or administrator settings page and compare the list of configured admin accounts against known legitimate accounts.
    Affected if Unexpected administrator accounts exist or credentials have been modified without authorization.
  4. Check for suspicious processes or cron jobs
    If you have shell access to the router (via telnet/ssh or debug mode), run 'ps' and check for unfamiliar processes. Also review any scheduled tasks or cron entries for unexpected commands.
    Affected if Unrecognized processes are running or unexpected commands appear in scheduled tasks.
  5. Inspect network connections and port listeners
    Use netstat or similar tools (if accessible) to list active network connections and listening ports. Look for unexpected outbound connections to unfamiliar IP addresses.
    Affected if The router has active connections to unknown external IP addresses, particularly on uncommon ports.

A user is affected if they have an ELECOM wireless LAN router with firmware older than the patched version, especially if the admin interface is accessible from untrusted networks.
