How to disable the SSLv3 protocol in Jetty to prevent Poodle Attack

Is there any specific exclusion list available which disables only SSLv3 ciphers are not TLSv1/2.

I have jetty 8, and upgrading to 9 is not an option now. My current jetty-ssl.xml looks as follows

<Configure id="Server" class="org.eclipse.jetty.server.Server">
<Call name="addConnector">
<Arg>
<New class="org.eclipse.jetty.server.ssl.SslSelectChannelConnector">
<Arg>
<New class="org.eclipse.jetty.http.ssl.SslContextFactory">
.........
</New>
</Arg>
<Set name="ExcludeCipherSuites">

<Item>SSL_RSA_WITH_NULL_MD5</Item>
<Item>SSL_RSA_WITH_NULL_SHA</Item>

<Item>SSL_RSA_WITH_AES_128_CBC_SHA</Item>
</Array>
</Set>
</New>
</Arg>
</Call>




still when i run "sslscan --no-failed --ssl3 localhost:443" i get

Supported Server Cipher(s):
Accepted SSLv3 128 bits DHE-RSA-AES128-SHA
Accepted SSLv3 128 bits AES128-SHA

Prefered Server Cipher(s):
SSLv3 128 bits DHE-RSA-AES128-SHA

Answer

I had to disable SSLv3 in an application where we integrate Jetty source code. Based on what I changed in code, I would guess you add the following:

<Set name="ExcludeProtocols">
    <Array type="java.lang.String">             
       <Item>SSLv3</Item>
    </Array>
</Set>

Give it a shot and let me know if it works for you.
