Reference? It's an SSL3 specific attack, so most servers are not
vulnerable because TLS will negotiate to the highest supported
protocol. So unless one of the client/server doesn't support TLS1.0
there's no issue. The only reason http is vulnerable is because
browsers do protocol downgrading, something strictly forbidden by the
spec.
Additionally, the man-in-the-middle must be able to control the padding
in the startup packet, which just isn't possible (no scripting language
in the client).
Since you can already specify the cipher list, couldn't you just add
-SSLv3 to the cipher list and be done?
Have a nice day,
