Security Metrics Scan Failed

We just had our quarterly scan by Security Metrics fail with the following reasons:

TCP  443  https  5.8 
Description: SSL / TLS Renegotiation Handshakes MiTM Plaintext Data Injection Synoposis: The remote service allows insecure renegotiation of TLS / SSL connections. Impact: The remote service encrypts traffic using TLS / SSL but allows a client to insecurely renegotiate the connection after the initial handshake. An unauthenticated, remote attacker may be able to leverage this issue to inject an arbitrary amount of plaintext into the beginning of the application protocol stream, which could facilitate man-in-the-middle attacks if the service assumes that the sessions before and after renegotiation are from the same 'client' and merges them at the application layer.
