Description

Nmap's man page mentions that "Nmap should never be installed with
special privileges (e.g. suid root) for security reasons.." and
specifically avoids making any of its binaries setuid during
installation. Nevertheless, administrators sometimes feel the need
to do insecure things. This module abuses a setuid nmap binary by
writing out a lua nse script containing a call to os.execute().

Note that modern interpreters will refuse to run scripts on the
command line when EUID != UID, so the cmd/unix/reverse_{perl,ruby}
payloads will most likely not work.
