Is it possible to root access control panel by exploiting exim if is this possible how hard it is on a rating of 1 to 10

I contacted a hacker for hiring to hack and get root access for a control panel and he said : i will execute it as the root user on the server this will make me gain control of the Exim server
As ISPmanager uses Exim

Is it even possible ?

Exim had a few critical vulnerabilities so depends on the version, what is it?
