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
In MIELE XGW 3000 ZigBee Gateway before 2.4.0, a malicious website visited by an authenticated admin user or a malicious mail is allowed to make arbitrary changes in the "admin panel" because there is no CSRF protection.

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

CSRF vulnerability in MIELE XGW 3000 ZigBee Gateway admin panel allows attackers to make arbitrary configuration changes by tricking authenticated administrators into visiting malicious websites or opening malicious emails. The application lacks anti-CSRF tokens on state-changing operations, enabling cross-site request forgery attacks.

MitigationImplement anti-CSRF tokens for all administrative actions and validate Origin/Referer headers to prevent cross-site request forgery attacks.

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
    Identify if the network device is a MIELE XGW 3000 ZigBee Gateway by checking the device label, web admin interface header, or SNMP sysDescr
    Affected if Device is a MIELE XGW 3000 ZigBee Gateway
  2. Check firmware version
    Access the admin web panel, navigate to System > Status or About section, and record the firmware version number
    Affected if Firmware version is below 2.4.0
  3. Verify anti-CSRF protection absence
    Inspect HTML forms in the admin panel (view page source) for any input fields containing 'csrf', 'token', or 'nonce'. Check if state-changing actions (e.g., save settings, add users, modify network config) submit forms without such tokens
    Affected if No anti-CSRF tokens are present in state-changing form submissions

If the device is a MIELE XGW 3000 with firmware below version 2.4.0 and the admin panel lacks anti-CSRF tokens on configuration forms, the environment is affected by this CVE.
