Synopsis :

The remote POP3 daemon allows credentials to be transmitted in clear
text.

Description :

The remote host is running a POP3 daemon that allows cleartext logins over
unencrypted connections. An attacker can uncover user names and
passwords by sniffing traffic to the POP3 daemon if a less secure
authentication mechanism (eg, USER command, AUTH PLAIN, AUTH LOGIN) is
used.
