workarounds: Please note CVE-2020-14479 does not have a fix in place. Induction Automation plans to correct this vulnerability in future product versions.
It is recommended to restrict interaction with the service to trusted machines. Only clients and servers with a legitimate procedural relationship should be permitted to communicate with the service. This can be done in various ways, most notably with firewall rules/allow listing.
