caused by the improper TLS configuration if FIPS 140-2 is enabled. A remote, unauthenticated attacker can exploit this
to obtain sensitive information by using man in the middle techniques.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
