Gen 4 VPS & Dedicated Servers Help

Update my Gen 4 VPS & Dedicated Server to address Exim vulnerability

Zero Day Initiative (ZDI) has reported a vulnerability with Exim Mail Transfer Agent (MTA), a third-party, open-source software responsible for routing and delivering email messages on servers. Core vendors have begun releasing patches to address this vulnerability. Therefore, we highly recommend Gen 4 VPS & Dedicated Servers with Exim to update to the latest patch.

Note:
  • Exim is only installed by default on Gen 4 VPS & Dedicated Servers using cPanel/WHM.
  • If Exim was manually installed, we recommend consulting your web developer or system administrator for information on updating your server.
  • If you're on an usupported Operating System (OS), we recommend moving to a supported OS server to receive continued security updates.
Warning: This article covers an advanced technical topic. If the steps are completed incorrectly, it's possible to make unwanted changes to your site. Therefore, we strongly recommend creating a backup before you proceed. Please review the full Statement of Support to learn more about available support for additional products and services.
