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 WAP interface in Trihedral VTScada (formerly VTS) 8.x through 11.x before 11.2.02 allows remote attackers to bypass authentication and read arbitrary files via unspecified vectors.

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

This is an authentication bypass vulnerability in the WAP (Wireless Application Protocol) interface of Trihedral VTScada SCADA software versions 8.x through 11.x before 11.2.02. The flaw allows unauthenticated remote attackers to read arbitrary files on the system, indicating a complete failure of the authentication mechanism in the WAP component.

MitigationUpgrade VTScada to version 11.2.02 or later to patch this vulnerability. If upgrading is not immediately possible, disable or restrict access to the WAP interface until the patch can be applied.

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. Locate VTScada installation
    Check common installation directories such as C:\Program Files\Trihedral\VTScada or /opt/vtscada, or search for vtscada.exe on Windows systems.
    Affected if VTScada software is found on the system
  2. Identify installed VTScada version
    Locate the version information in the installation folder, typically in a file named about.txt, version.ini, or check the executable properties of vtscada.exe.
    Affected if The version number matches 8.x through 11.x before 11.2.02, or specifically equals any of these: 10.1.05, 10.1.06, 10.1.07, 10.1.12, 10.0.11, 10.0.13, 10.0.14, 10.0.16, 10.0.17, 11.1.05, 11.1.06, or 11.1.09
  3. Determine if WAP interface is enabled
    Check the VTScada configuration or services for the WAP (Wireless Application Protocol) component. This may be visible in the VTScada Service Manager, configuration files, or running network services on ports typically used by WAP.
    Affected if The WAP interface is active, listening on a network port, or configured to run
  4. Verify WAP authentication configuration
    Inspect the WAP configuration settings within VTScada to confirm authentication is not properly enforced, or attempt a test request to the WAP endpoint without credentials to observe if access is granted.
    Affected if The WAP interface accepts unauthenticated requests or shows no authentication challenge

You are affected if VTScada is installed with a version between 8.x and 11.x prior to 11.2.02 and the WAP interface is enabled or accessible on the network.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade VTScada to version 11.2.02 or later to patch this vulnerability. If upgrading is not immediately possible, disable or restrict access to the WAP interface until the patch can be applied.

Recommended fix High confidence

VTScada 11.2.02 or later

  1. Download VTScada version 11.2.02 or later from the official Trihedral website or trusted distribution channel
  2. Review the official upgrade documentation for VTScada
  3. Ensure a complete backup of the current VTScada system including all configuration files, applications, and databases
  4. Test the upgrade in a non-production environment before deploying to production
  5. Stop all VTScada services prior to upgrade installation
  6. Install the upgraded VTScada version 11.2.02 or later
  7. Verify the WAP interface authentication is functioning correctly after upgrade
  8. Confirm that arbitrary file access is no longer possible without proper authentication
