tnftp "savefile" Arbitrary Command Execution

Description

This module exploits an arbitrary command execution vulnerability in
tnftp's handling of the resolved output filename - called "savefile" in
the source - from a requested resource.

If tnftp is executed without the -o command-line option, it will resolve
the output filename from the last component of the requested resource.

If the output filename begins with a "|" character, tnftp will pass the
fetched resource's output to the command directly following the "|"
character through the use of the popen() function.
