View CVE Details Affected Products ABB Ability Zenon Vendor: ABB Product Version: ABB IIoT services with MongoDB (4.2) installed on ABB Ability Zenon: vers:all/* Product Status: known_affected Remediations Mitigation ABB recommends the following specific mitigations for users with IIoT services utilizing MongoDB (version 4.2) on ABB Ability Zenon to reduce risk: Mitigation Replace bundled MongoDB with a supported version if IIoT services are required: Mitigation Where IIoT functionality is required, the bundled MongoDB instance can be replaced with a supported and patched version through manual configuration. Mitigation The following zenon online help section explains the process of installing and using your own MongoDB database: zenHelpViewer. Mitigation Uninstall IIoT Services wherever it's not required: Mitigation 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 advice on how to keep your system secure.
