The default connector as written in <confluence_install>/conf/server.xml uses sslProtocol="TLS". This should only enable TLS connectors, but it also enables SSLv3. Our documentation and the included server.xml need to be updated to reflect the correct settings to enable only TLS.
Reproduction steps:
- Follow the instructions at Running Confluence Over SSL or HTTPS to enable SSL for Confluence
- Use SSLScan to see what connections are available
Expected behavior
Only TLS connections should be available
Actual behavior
TLS and SSLv3 connections are available, shown in the following:
