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 affected TBox RTUs are missing authorization for running some API commands. An attacker running these commands could reveal sensitive information such as software versions and web server file contents.

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

TBox RTUs lack proper authorization checks on certain API endpoints, allowing unauthenticated attackers to execute specific API commands that expose sensitive system information including software versions and web server file contents.

MitigationImplement role-based access control and authorization validation on all API endpoints to ensure only authenticated and authorized users can access sensitive system information.

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 the device as an Ovarro TBox RTU
    Examine the device or its network documentation to confirm it is an Ovarro TBox model from the affected product line (Ms Cpu32, Ms Cpu32 S2, Lt2, Tg2, or Rm2).
    Affected if The device is one of the listed Ovarro TBox models.
  2. Determine the firmware version
    Access the device's web interface or use its administrative console to retrieve the installed firmware version. Compare the version number against the affected range <= 1.50.598.
    Affected if The firmware version is 1.50.598 or lower.
  3. Check for exposed API endpoints
    Attempt to access the device's web API endpoints without providing authentication credentials. Observe whether the device returns sensitive system information such as software versions or file contents.
    Affected if The API endpoints respond to unauthenticated requests with sensitive system data.
  4. Verify API authorization behavior
    Send API requests to known endpoints (such as those that expose version or file information) without an active session or API key. Inspect the HTTP response for success codes and returned data.
    Affected if Unauthenticated API requests successfully return sensitive information that should require authorization.

A system is affected if it is an Ovarro TBox RTU running firmware version 1.50.598 or lower AND its API endpoints are accessible without authentication, allowing exposure of sensitive system information.
