[New-bugs-announce] [issue45005] Two Layers of SSL/TLS

[Mjbmr]

New submission from Mjbmr <mjbmri at gmail.com>:

A simple script, trying connect to second ssl through first sever doesn't work:

import socket, ssl

sock = socket.socket()
sock.connect(('<FIRST_SERVER>', 443))
ctx = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE
sock = ctx.wrap_socket(sock)
sock.send(b'CONNECT <SECOND_SERVER>:443 HTTP/1.1\r\n\r\n')
print(sock.recv(1024))
ctx = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE
sock = ctx.wrap_socket(sock)
sock.do_handshake()
sock.send(b'CONNECT ifconf.me:80 HTTP/1.1\r\n\r\n')
print(sock.recv(1024))


b'HTTP/1.1 200 Connection established\r\n\r\n'
Traceback (most recent call last):

    self._sslobj.do_handshake()
