What to do
Workaround: Workarounds are specific measures that a user can take to help block an attack. ABB has tested the following workarounds. Although these workarounds will not correct the underlying vulnerability, they can help block known attack vectors. When a workaround reduces functionality, this is identified below as “Impact of workaround”. – Physically disconnect the ethernet port if embedded web server is not being used. Impact of workaround The embedded web server and all its functionalities, incl. load monitoring, alarms, remote configuration, etc. will not be accessible. However, the product will continue functioning as normal based on configured control parameters.
