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
Incorrect access control in the Web management interface in Each Italy Wireless Mini Router WIRELESS-N 300M v28K.MiniRouter.20190211 allows attackers to arbitrarily change the administrator username and password via sending a crafted GET request.

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 Each Italy Wireless Mini Router WIRELESS-N 300M (v28K.MiniRouter.20190211) has an incorrect access control vulnerability in its web management interface. Attackers can send a crafted GET request to arbitrarily change the administrator username and password without proper authentication or authorization checks. This allows complete takeover of the device's admin account.

MitigationApply any available firmware update from the manufacturer; if none exists, replace the device as it cannot be safely operated. In the interim, disable remote web management access, restrict management interface to trusted IPs only via firewall rules, and monitor for unauthorized configuration changes.

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. Confirm device model and firmware version
    Access the router's web interface or check the device label. Look for 'Each Italy Wireless Mini Router WIRELESS-N 300M' with firmware version v28K.MiniRouter.20190211. If your device is a different model or version, this specific CVE may not apply.
    Affected if The device is an Each Italy Wireless Mini Router WIRELESS-N 300M running firmware v28K.MiniRouter.20190211.
  2. Verify web management interface is accessible
    Check if the router's web interface (typically on ports 80 or 443) is reachable from the network. Attempt to access the login page using the router's IP address in a web browser.
    Affected if The web management interface is exposed and reachable on the network.
  3. Inspect current administrator accounts
    Log into the router's web interface and navigate to the administration or user management section. Review the list of configured administrator accounts for any unauthorized or unexpected accounts.
    Affected if Multiple administrator accounts exist or an unfamiliar admin account is present.
  4. Check for recent configuration changes
    If available, review the router's logs or configuration backup files for timestamps of recent administrative changes, especially password or account modifications you did not initiate.
    Affected if Password or account changes are present in logs that you did not perform.
  5. Test for unauthorized password change capability
    From an unauthenticated state, attempt to access the password change endpoint (if known) or observe whether the router accepts credential changes without valid session cookies or authentication tokens.
    Affected if The router allows password or username changes without being logged in as an administrator.

You are affected if you are using an Each Italy Wireless Mini Router WIRELESS-N 300M with firmware v28K.MiniRouter.20190211 and its web management interface is accessible on your network.
