IIRC
there were measure attempted to make this happen, but they seem to
have
been unsuccessful.
Do we have any such report? Which is the used configuration?
I did some tests here, and also I tried to find such cases but I did not
found. The traffic in my tests always re-encrypted before sent.
I have two users mention replication of this in squid-users.
The replicated case seems to be:
http_port ... ssl-bump
cache_peer ... parent ...
always_direct deny all
Yep this is true.
I think we should consider it as a bug.
What I am actually getting is the following:
<=https==> [proxy] <===http==>[proxy2]<==https==>
Yes that appears to be it. The problems being that a) proxy2 may not
have OpenSSL feature built in to re-crypt, and b) that the middle
channel is cleartext
The easier solution is to add a check in FwdState::connectStart() in
forward.cc file:
if (fs->_peer && request->protocol == AnyP::PROTO_HTTPS) {
anErr = errorCon();
fail(enErr);
return;
}
The above will just disable any ssl-bumped connection through any parent
As a short-term it may be okay. I don't see that working well with
normal proxied https:// URL requests, but those seem relatively rare.
Also we should define if the "allow-direct" http-port options will have
any effect in ssl-bump...
allow-direct being an accelerator mode option I think it will be
irrelevant once ssl-bump mode is created.
Since always_direct is documented as recommended, allow-direct behaviour
would seem to be implied for ssl-bump mode.
The ideal I think is to use "CONNECT ..." when connecting through a
parent proxy. But this is requires more development, I do not know if it
is required and if we need it...
Yes. I imagine the MITM crowd doing interception of LAN traffic from
local workmates and funneling up to a corporate proxy will want that.
