cPanel is an easy-to-use control panel that gives web hosts and the website owners they serve, the ability to quickly and easily manage their servers and websites. Web Host Manager (WHM) is a part of the cPanel software, often used by resellers and system administrators.
Under certain conditions it is possible for an attacker to view the MySQL grants for user databases, including usernames, remote access hosts and passwords due to the datastore files under the /var/cpanel/databases having invalid permissions.
