Strange warning

What is this supposed to mean?

"To prevent network sniffing from allowing a fourth party to establish
a connection to a peer using the information sent out-of-band to the
other peer and thus spoofing the client, the configuration information
SHOULD always be transmitted using an encrypted connection."

It's right at the bottom of a very big Section 4.3.1.

I might guess that this relates to the ICE ufrag and pwd, but it's
well out of place if that is the case and very confusing either way.
