<bug_affected>POP3 with non encrypted authentications</bug_affected>
<bug_vulnerability_class>Missing Encryption</bug_vulnerability_class>
<bug_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.</bug_description>
<bug_solution>Contact your vendor for a fix or encrypt traffic with SSL / TLS using stunnel.</bug_solution>
