Re: [jetty-users] Website works but SSL Labs is reporting vulnerabilitie

Instead of replacing the exclusion list, perhaps you should just add to the exclusion list.

  <Call name="addExcludeCipherSuites">

    <Arg>

      <Array type="String">

        <Item>.*_DHE_.*$</Item>

      </Array>

    </Arg>

  </Call>

Also, when it comes to SSL/TLS, you need to keep your Jetty and Java installations up to date.

Jetty 9.3.8 is out, and it adds more cipher exclusions to satisfy other SSL/TLS concerns (re: Chrome, SLOTH)

Jetty 9.3.3.v20150827

I have two problems the Qualys SSL Test is reporting with one of my Jetty-hosted websites and I'm not sure how to fix them.

Both are preventing this website from getting an "A" rating. I'm at a "B" now.

First: "This server supports weak Diffie-Hellman (DH) key exchange parameters."
There were a half-dozen weak ciphers I was able to disable. Only one is still being reported active:
TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA

But I am doing this:
<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_3.dtd">

    <Item>TLS_DHE_RSA_WITH_AES_128_CBC_SHA</Item>
    <Item>TLS_DHE_RSA_WITH_AES_128_GCM_SHA256</Item>
    <Item>TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA</Item>
  </Array>
  </Set>
  <Set name="useCipherSuitesOrder"><Property name="jetty.sslContext.useCipherSuitesOrder" default="true"/></Set>
</Configure>

I specifically exclude the cipher SSL Labs is complaining about.

The other problem: The SSL Labs test says that my certificate chain is incomplete. But I have the Comodo certificate for the website in the server's keystore, and I have all three intermediate certificates in the truststore.

Any ideas?

Thanks.
