This Metasploit module creates a local user with a username/password
and root-level privileges. Note that a root-level account is not
required to do this, which makes it a privilege escalation issue. Note
that this is pretty noisy, since it creates a user account and creates
log files and such. Additionally, most (if not all) vulnerabilities in
F5 grant root access anyways.
