ETS is not a Java-based software and does not use Java components. It is therefore not prone to the log4j security hole. If you have installed 3rd-party extensions in ETS (like plug-in software or apps from manufacturers), please contact these manufacturers for details on the software components they use.
Where can I find more information?
