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
An attacker with low privileges may be able to read files from specific directories on the device, potentially exposing sensitive information.

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

This is an authenticated file disclosure vulnerability allowing users with low privileges to read files from specific directories on the device. The vulnerability likely involves improper access control or path traversal in file read operations, potentially exposing sensitive configuration or system files.

MitigationApply vendor patches when available and review user privilege assignments to ensure only necessary permissions are granted. If no patch exists, restrict network access to trusted users and monitor for unauthorized file access attempts.

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 Sick TDC X401GL device in your environment
    Check your asset inventory or network scan results for devices with hostname, MAC OUI (Sick GmbH), or product identifier matching the TDC X401GL model
    Affected if The device model matches Sick TDC X401GL and is network-accessible
  2. Confirm firmware version
    Access the device web interface or use SNMP/sysinfo queries to retrieve the installed firmware version. Check device labeling or management console for firmware build information
    Affected if Any firmware version is installed, as all versions are affected according to the advisory
  3. Verify web management interface accessibility
    Attempt to reach the device HTTP/HTTPS management port from your detection point. Check firewall rules and network segmentation for exposure to untrusted networks
    Affected if The web interface is accessible from network segments containing low-privilege or untrusted users
  4. Review user account privilege levels
    Log into the device administration panel and enumerate user accounts. Check for users assigned to roles below administrator or operator level
    Affected if Low-privilege user accounts exist on the device
  5. Inspect for anomalous file access patterns
    Review device logs, access logs, or SIEM records for file read operations targeting system directories (etc, config, var) originating from authenticated sessions
    Affected if File read operations to sensitive directories are logged from non-administrator accounts

You are affected if a Sick TDC X401GL device with any firmware version is in your environment and low-privilege users can access the web management interface.
