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

When you used <Set name="ExcludeCipherSuites">

You undid the existing exclusions in Jetty 9.3.3

https://github.com/eclipse/jetty.project/blob/jetty-9.3.3.v20150827/jetty-util/src/main/java/org/eclipse/jetty/util/ssl/SslContextFactory.java#L252-L259

    public SslContextFactory(boolean trustAll)
    {
        setTrustAll(trustAll);
        addExcludeProtocols("SSL", "SSLv2", "SSLv2Hello", "SSLv3");
        setExcludeCipherSuites(
                "SSL_RSA_WITH_DES_CBC_SHA",
                "SSL_DHE_RSA_WITH_DES_CBC_SHA",
                "SSL_DHE_DSS_WITH_DES_CBC_SHA",
                "SSL_RSA_EXPORT_WITH_RC4_40_MD5",
                "SSL_RSA_EXPORT_WITH_DES40_CBC_SHA",
                "SSL_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA",
                "SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA");
   }

If you use Jetty 9.3.8, you'll find the exclusion list is more strict ...

https://github.com/eclipse/jetty.project/blob/jetty-9.3.8.v20160314/jetty-util/src/main/java/org/eclipse/jetty/util/ssl/SslContextFactory.java#L252-L255

    public SslContextFactory(boolean trustAll)
    {
        setTrustAll(trustAll);
        addExcludeProtocols("SSL", "SSLv2", "SSLv2Hello", "SSLv3");
        setExcludeCipherSuites(
                "^.*_RSA_.*_(MD5|SHA|SHA1)$",
                "SSL_DHE_DSS_WITH_DES_CBC_SHA",
                "SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA");
    }

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.
