Announcement - Urgent cPanel update
Dear Valued Clients,
An exploit for Exim was identified and a patch for the exploit was released by cPanel for the End Of Life Versions 70 and 76.
What is Exim?
Exim is the mail server software cPanel & WHM servers use.
How to protect yourself?
Kindly perform an upgrade to a supported version of cPanel & WHM that are immune to the exploit.
How to check your current Exim version?
You can run this command on the server:
rpm -q exim
The output will show you the Exim versions that are installed, and should look something like what’s below:
For Version 78: exim-4.92-1.cp1178.x86_64
For Version 80: exim-4.92-1.cp1180.x86_64
For Version 70 and 76: exim-4.91-4.cp1170.x86_64
Those cPanel Dedicated/VPS clients who not display updated versions after tryout the above steps may perform cPanel update urgently or contact support team by submitting a ticket at firstname.lastname@example.org
How to update cPanel version?

2) Navigate to cPanel >> Upgrade to Latest Version
3) Click the Click to Upgrade button.
4) At the end you will see a message Upgrade complete
When you update your cPanel version, It’s possible that the update will be blocked with an error similar to this:
A system upgrade was not possible due to the following blockers:
[2019-06-07 02:02:51 +0200] W [FATAL] - You must migrate from EA3 to EA4 before upgrading to v78 or newer. You can do so by running /usr/local/cpanel/scripts/migrate_ea3_to_ea4 or via WHM’s EasyApache 4 Migration interface. For more information please see: https://go.cpanel.net/EA4Migration
If you encounter this error, you must manually adjust your /etc/cpupdate.conf file to the example below:
CPANEL=11.76 RPMUP=daily SARULESUP=daily STAGING_DIR=/usr/local/cpanel UPDATES=daily
Once you have completed this update (upcp) please set this back to the following:
CPANEL=release RPMUP=daily SARULESUP=daily STAGING_DIR=/usr/local/cpanel UPDATES=daily
This will allow you to upgrade to newer versions of cPanel & WHM once you have migrated to EasyApache 4.
What if you not yet migrate to EasyApache4?
