If your web server and all of the interpreters and programs it runs are
competently written, there is no way for an attacker to get root
access, or even run a shell command.  Web applications and the
special-purpose interpreters they run on are often incompetently
written.

I select the message I want to reply to, and then I click the “Reply”
