By default, cPanel provides a lot of information in the Server Information Link. However, there maybe some information provided that you may not want users knowing.
This can be corrected by disabling the "Server Status Viewer" In the Feature Manager
According to the following article:
Go to Home » Packages » Feature Manager » Feature Lists in WHM
Select the Feature list you wish to change and press Edit
Then remove the check mark in the "Server Status Viewer"
The information that will display will only be what is relevant to a user using cPanel.
