How to get a reverse Shell / VNC from a writable directory on a remote web server.

[AsTriXs <astrixs () gmail com>]

Hi,

I have found a few writable directories on a remote web server on
which I am doing a Pen-Test.
How do I setup a reversell of a VNC from this stage?
What tools can I use?
Does Metasploit provide an option?
What would be the procedure to achieve the same?

Thanks,
