ABB recommends the following mitigation measures: - Replace bundled MongoDB with a supported version if IIoT services are required: - Where IIoT functionality is required, the bundled MongoDB instance can be replaced with a supported and patched version through manual configuration. - The following zenon online help section explains the process of installing and using your own MongoDB database: zenHelpViewer - Uninstall IIoT Services wherever it’s not required: - If IIoT Services are not required, they can be removed using the Control panel uninstaller. This eliminates the dependency on MongoDB without affecting other zenon components. Refer to section “General security recommendations” for further advise on how to keep your system secure.
