It's not practical to stick with terminal in all situations. That's the problem. For example if you have dozen or several dozen sites then using Terminal is a simple nightmare. Same goes if you have clients whom you need to give access but they don't know how to use terminal. Same goes if you running web hosting business.

These exploits / bugs can happen in anything not just in control panels. Everyday developers and security experts find this kind of things in operating systems and other modules like Apache, Sql servers, ftp servers etc. That's why always get soo many patches and updates. It's an occupational hazard and never ending war. All we can do is make sure everything is upto date and have solid security measures implemented in your servers.

It would be impractical if your in a hosting business or some sort, but for personal websites, using terminal and filezilla to manage your sites typically will work.  I hardly need terminal really, the only time I access it is for tiny changes to settings and for creating a new virtual host (which I use a script from the internet to make it easier).  The rest is uploading changes to my site which is quite straightforward and is roughly the same as if there was a panel.
