Injecting the VNC Server Remotely Using MetaSploit(MSF Venom)

The Virtual Network Computing (VNC) is a graphical desktop sharing system that uses to remotely control another computer. We can inject a VNC server remotely using the Metasploit payload for the VNC injection. In this recipe, we will learn how to inject the VNC server remotely.

I had to set this up the other day in order to connect to a remote server and use something that was only possible with a GUI. No cli unfortunately. This is how to do it.

First, we need to install VNC Server

$ sudo -i $ apt-get install gnome-core xfce4 firefox $ apt-get install vnc4server

The installed packages will look like this

$ dpkg -l | grep vnc ii vnc4server 4.1.1+xorg4.3.0-37ubuntu5 amd64 Virtual network computing server software

Add a user for VNC.

$ adduser vncuser

Specify a vnc password.

$ su - vncuser $ vncserver password: xxxx

Just in case backup the xstartup file.

$ cp ~/.vnc/xstartup ~/.vnc/xstartup.bak

Edit the configuration file.

$ vim ~/.vnc/xstartup #!/bin/sh unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS startxfce4 & [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic &

Kill vncserver with this command.

$ vncserver -kill :1

Paste this start script.

$ sudo vim /etc/init.d/vncserver #!/bin/bash unset VNCSERVERARGS VNCSERVERS="" [ -f /etc/vncserver/vncservers.conf ] && . /etc/vncserver/vncservers.conf prog=$"VNC server" start() { . /lib/lsb/init-functions REQ_USER=$2 echo -n $"Starting $prog: " ulimit -S -c 0 >/dev/null 2>&1 RETVAL=0 for display in ${VNCSERVERS} do export USER="${display##*:}" if test -z "${REQ_USER}" -o "${REQ_USER}" == ${USER} ; then echo -n "${display} " unset BASH_ENV ENV DISP="${display%%:*}" export VNCUSERARGS="${VNCSERVERARGS[${DISP}]}" su ${USER} -c "cd ~${USER} && [ -f .vnc/passwd ] && vncserver :${DISP} ${VNCUSERARGS}" fi done } stop() { . /lib/lsb/init-functions REQ_USER=$2 echo -n $"Shutting down VNCServer: " for display in ${VNCSERVERS} do export USER="${display##*:}" if test -z "${REQ_USER}" -o "${REQ_USER}" == ${USER} ; then echo -n "${display} " unset BASH_ENV ENV export USER="${display##*:}" su ${USER} -c "vncserver -kill :${display%%:*}" >/dev/null 2>&1 fi done echo -e "\n" echo "VNCServer Stopped" } case "$1" in start) start $@ ;; stop) stop $@ ;; restart|reload) stop $@ sleep 3 start $@ ;; condrestart) if [ -f /var/lock/subsys/vncserver ]; then stop $@ sleep 3 start $@ fi ;; status) status Xvnc ;; *) echo $"Usage: $0 {start|stop|restart|condrestart|status}" exit 1 esac

Make it executable.

$ chmod +x /etc/init.d/vncserver

Set up some vnc configurations

$ mkdir -p /etc/vncserver $ vim /etc/vncserver/vncservers.conf VNCSERVERS="1:vncuser" VNCSERVERARGS[1]="-geometry 1024x768"

Add vnc to start on boot

$ update-rc.d vncserver defaults 99

Restart the system.

$ reboot

VNC Server listens on port 5901 by default. You can connect to it via a VNC Client with something like:

What Are Some Cool Things You Can Do With Linux That You Cannot With Windows?

You can let a lot of people work for you to do security audits of software you are using. You can relax more that your software is probably less abusive than what commercial vendors provide you with. You can, much easier and less expensively host server applications and network services on a Linux box. It is not too cool but very practical and less painful than on Windows. Other than that, you…
