If you have hired a third party to perform a security scan of your website, they may have identified the following as unpatched server issues affecting your account.
CVE: 2017-15906
CVE: 2018-15919
Both of these are issues are related to OpenSSH as provided by CentOS/RedHat. The first thing is to assure all clients on a cpanel server that these are not security issues that affect you, or the server. Firstly here is an official answer from Cpanel in regards to this.
The first thing to note is that cPanel have actually patched this issue in the first instance, and in the second instance it is marked as a false positive and Red Hat have advised it as "Will not fix."
Additionally, SSH is not an available service for clients on our shared cpanel servers.
