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 installed Schneider Electric HVAC product
    Check installed programs or application metadata for either 'SoMachine HVAC' or 'EcoStruxure Machine Expert - HVAC'
    Affected if Either product is present on the system
  2. Determine the installed version of EcoStruxure Machine Expert - HVAC
    Open the software and navigate to Help > About, or check the program's properties in the installation directory for version information
    Affected if Version is found to be below 1.4.0
  3. Determine the installed version of SoMachine HVAC
    Open the software and navigate to Help > About, or check the program's properties in the installation directory for version information
    Affected if Version is found to be below 2.1.0
  4. Verify the web commissioning interface is accessible
    Check if the built-in web server or commissioning web interface is enabled and accessible from the application
    Affected if The web-based commissioning feature is available and can be reached from a browser within the software context

A user is affected if they have either EcoStruxure Machine Expert - HVAC version below 1.4.0 or SoMachine HVAC version below 2.1.0 installed, and the web commissioning functionality is accessible.
