ICS Advisories

Risk evaluation

ABB is aware of publicly reported vulnerabilities affecting MongoDB 4.2, which is bundled within the IIoT Services of the affected product versions. MongoDB 4.2 has reached end-of-life and contains multiple known security vulnerabilities. An attacker who successfully exploits these vulnerabilities could potentially access sensitive information, cause denial of service, or disrupt system availability.

Mitigation summary

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.
