In 16.04 the NetworkManager package used to carry this patch:
http://bazaar.launchpad.net/~network-manager/network-manager/ubuntu/view/head:/debian/patches/Filter-DNS-servers-to-add-to-dnsmasq-based-on-availa.patch
It fixed the DNS setup so that when I'm on the VPN, I am not sending unencrypted DNS queries to the (potentially hostile) local nameservers.
This patch disappeared in an update. I think it was present in 1.2.2-0ubuntu0.16.04.4 but was dropped some time later.
This security bug exists upstream too: https://bugzilla.gnome.org/show_bug.cgi?id=746422
It's not a *regression* there though, as they didn't fix it yet (unfortunately!) |
* Impact
When using a VPN the DNS requests might still be sent to a DNS server outside the VPN when they should not
* Test case
Configure the system to send all the traffic to a VPN, do a name resolution, the request should not go to the public DNS server (to be checked by capturing the traffic by example with wireshark)
* Regression potential
The code change the handling of DNS servers when using a VPN, we should check that name resolution still work whne using a VPN in different configurations

[Impact]
When using a VPN the DNS requests might still be sent to a DNS server outside the VPN when they should not
[Test case]
1) Set up a VPN with split tunneling:
a) Configure VPN normally (set up remote host, any ports and options needed for the VPN to work)
b) Under the IPv4 tab: enable "Use this connection only for the resources on its network".
c) Under the IPv6 tab: enable "Use this connection only for the resources on its network".
2) Connect to the VPN.
3) Run 'systemd-resolve --status'; note the DNS servers configured:
a) For the VPN; under a separate link (probably tun0), note down the IP of the DNS server(s). Also note the name of the interface (link).
b) For the "main" connection; under the link for your ethernet or wireless devices (wl*, en*, whatever it may be), note down the IP of the DNS server(s). Also note the name of the interface (link).
4) In a separate terminal, run 'sudo tcpdump -ni <the main interface> port 53'; let it run.
5) In a separate terminal, run 'sudo tcpdump -ni <the VPN interface> port 53'; let it run.
6) In yet another terminal, issue name resolution requests using dig:
a) For a name known to be reachable via the public network:
'dig www.yahoo.com'
b) For a name known to be reachable only via the VPN:
'dig <some DNS behind the VPN>'
7) Check the output of each terminal running tcpdump. When requesting the public name, traffic can go through either. When requesting the "private" name (behind the VPN), traffic should only be going through the interface for the VPN. Additionally, ensure the IP receiving the requests for the VPN name is indeed the IP address noted above for the VPN's DNS server.
If you see no traffic showing in tcpdump output when requesting a name, it may be because it is cached by systemd-resolved. Use a different name you have not tried before.
[Regression potential]
The code change the handling of DNS servers when using a VPN, we should check that name resolution still work whne using a VPN in different configurations
