Whether passwords are sent over the network in plaintext or encrypted
text is irrelevant.  The server grants access when given the login
string S.  If someone eavesdrops on the net, stores string S and later
plays back string S in order to gain access, it doesn't matter whether
the string S is plaintext or encrypted.

To get around this problem one needs to use public-key cryptography
and an interactive login protocol.
