Just changing the setting will only cause your database server to error out on restart - you also need to create certificates and put them into the server directory.
So whoever does this change must know what they are doing (to some extent).
Once SSL has been enabled, a cunning attacker may be able to steal the server's private key (if I understood the vulnerability correctly) and then launch man-in-the-middle attacks, i.e. impersonate the server, to eavesdrop on encrypted communication.
The remedy would be to create a new key pair for the server.

Thanks, this really helps. Currently we are not creating certificate and working in non SSL mode.
