A+ grade with TLS 1.0 on #808

Open rfrovarp opened 4 years ago

rfrovarp commented 4 years ago

We received an A+ grade with TLS 1.0 support still enabled. We don't have any ciphers enabled that would work via TLS 1.0, so while the protocol I guess is still on, it couldn't be used. We're fixing the configuration on our side obviously. However, it seemed odd to see that when the grade probably should be capped due to the protocol being enabled.

Related #690 as that is the condition this is triggering in. Underlying vhost still has 1.1 and 1.0 support.

Hi @rfrovarp

Your server supports No-SNI and it sends a valid response when there is no server name in the ClientHello. For our current grading, we only consider the configuration from the requested domain. For NoSNI it is possible that we are hitting some other domain hence we do not penalize in such a situation.

In the upcoming release, we have started marking the NoSNI protocols on the UI. I will update you once we release this change. In the future, we will consider penalizing for server responding to a NoSNI request as all the new/reference clients support SNI.

Thanks and Regards, Nauman Shah

Funny little thing possibly related - In the nosni case, the cert is aparently not checked or considered at all? Tiktok (don't ask), should be nuked from the planet but alas, it presents a cert that is not trusted by the same devices as the SNI case.

.. yet the site receives an A+ rating?

As someone in NA, fInding what in the hell snssdk.com even is leads down some rather bizzare paths.
