Remediations
MitigationDigi International recommends users upgrade to Digi Connect EZ or Digi Connect EZ TS as a long term solution. If users are not able to upgrade at this time, the following actions should be taken: Vendor fixFor Digi PortServer TS: Enable HTTPS on the web server. MitigationAlternatively, disable the web server when it is not actively being used for configuration.
MitigationCompensating control: If you cannot apply the HTTPS configuration, restrict access via firewall or VPN. Vendor fixFor Digi One SP / Digi One SP IA / Digi One IA: Disable the web server. If you cannot apply the HTTPS configuration, restrict access via firewall or VPN.
MitigationThe following deployment practices are the recommended means of reducing exposure: Deploy the device on a trusted network segment, not exposed to untrusted or public networks.
MitigationPlace the device behind a firewall or VPN and restrict access to the web management interface to trusted administrative hosts only. MitigationSafeguard administrator credentials, since exploitation requires authenticated administrator access to write the affected fields.
