SSL Perfect Forward Secrecy Cipher Suites Supported
This entry from Security Metrics indicates that they are able to see which SSL Perfect Forward Secrecy Ciphers are supported.
SSL protocol negotiation is part of the protocol. The ability to negotiate this does not indicate a specific vulnerability.
Part of the protocol for SSL requires negotiation of the SSL encryption to be used between the hosts. While this displays what is possible, it does not give an attacker any particular advantage.
