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
The device is deployed with weak and publicly known default passwords for certain hidden user levels, increasing the risk of unauthorized access. This represents a high risk to the integrity of the system.

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

The vulnerability involves network devices shipped with weak, publicly known default passwords for hidden administrative user accounts. Attackers with knowledge of these default credentials can gain unauthorized privileged access to the device, compromising system integrity and potentially enabling further network penetration.

MitigationImmediately change all default passwords for hidden accounts, disable unused hidden accounts, and implement a firmware update that enforces unique strong passwords on first login and removes or文档ates hidden backdoor accounts.

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
    Identify if the target device is a Sick Tdc X401gl by checking the device label, web interface, or system information page. Note that all firmware versions are affected.
    Affected if The device is a Sick Tdc X401gl
  2. Enumerate user accounts on the device
    Access the device administrative interface and navigate to user management or account settings. Look for any hidden, undocumented, or non-standard administrative accounts beyond the expected named users.
    Affected if Hidden or undocumented administrative user accounts exist on the device
  3. Check for default or weak passwords in use
    Review the authentication configuration or attempt to verify whether any hidden accounts are using default, factory-set, or easily guessable passwords. Compare against publicly known default credentials for this device model.
    Affected if Hidden accounts are using default, publicly known, or weak passwords
  4. Review authentication logs for compromise
    Examine device logs, system logs, or authentication audit trails for successful or failed login attempts using default credentials or unusual privileged account activity.
    Affected if Logs show successful logins using default credentials or unauthorized privileged access

If the device is a Sick Tdc X401gl with hidden administrative accounts using default or publicly known passwords, the environment is affected by this vulnerability.
