CSWSH

A command-line tool designed to test and connect to a WebSocket which are vulnerable to Cross-Site WebSocket Hijacking vulnerability.

About

CSWSH tool can connect to both standard and socket.io based WebSockets.

  • A standard websocket will have the functionality of sending messages to the server and receiving messages from the server.
  • A socket.io based websocket will have only the ping functionality to check if the connection is successful or not.

Requirements

CSWSH works with Python 3 and has few dependencies.

To install these dependencies, navigate to the source directory and execute pip3 install -r requirements.txt

Usage

CSWSH tool provides the below options while connecting to a websocket server.

For standard websocket

$ python3 cswsh.py "wss://echo.websocket.org"

For socket.io based websocket

$ python3 cswsh.py "https://example.com/socket.io/" -sio

On successful connect, send websocket ping message 2probe and server will respond with 3probe as an acknowledgment of the successful connection.

Add custom headers

To add custom headers in the request use -h option

$ python3 cswsh.py "wss://echo.websocket.org" -h "Authorization: Bearer AbCdEf123456"

Add cookies

To add cookies in the request use -c option

$ python3 cswsh.py "wss://echo.websocket.org" -c "sessionID=AbCdEf123456"

$ python3 cswsh.py "wss://echo.websocket.org" -o "http://localhost:8080"
