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

[Irene Abezgauz <irene.abezgauz () gmail com>]

Just how writeable is writeable?  Can you upload anything of anything or
are you limited? Can you execute things from the dir? Is it limited by
the server?
What server is it? Maybe it has a few other vulnerabilities that will be
easier to exploit.

In cases like this I usually upload netcat and take it from there.
The main problem is that it's not trivial because you can't really
upload binaries easily with the PUT method, so you need to upload a
non-binary version and then find a way to make it useable.

More detail will help in this case.

Btw, questions like this are better to be asked at
webappsec () securityfocus com which is more web oriented.

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

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,
