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 checksWork through these to decide whether this CVE applies to you.
-
Identify if EcoStruxure Control Expert is installedLook for EcoStruxure Control Expert in installed programs or check for the installation directory typically under Program Files/Schneider ElectricAffected if The software is present on the system
-
Determine the installed version of EcoStruxure Control ExpertCheck the version information in the application's About dialog, installation logs, or registry entries under the software's installation pathAffected if The installed version is 15.1 or higher
-
Verify the console server service is present and runningOpen Services console (services.msc) and look for a service related to console server functionality, or check running processes for console server componentsAffected if The console server service or process is running on the system
-
Check console server service configuration and permissionsOpen Services console, right-click the console server service, select Properties, and review the Log On tab to see under what account the service runsAffected if The service runs with elevated privileges or with an account that has excessive permissions
