Intellipeer POP3 Server User Account Enumeration

This script is Copyright (C) 2004-2013 Tenable Network Security, Inc.


Synopsis :

The remote server is vulnerable to information disclosure.

Description :

The remote POP3 server (probably intellipeer pop3 server) is
vulnerable to an account enumeration issue.

If an attacker attempts to log into the remote host by submitting a
bogus username, then the server will reply with a specific error
message if the account is nonexistent, while it will reply with
another message if the account exists.

An attacker may use this flaw to set up a brute-force attack against
the remote server to obtain a list of valid user names and accounts.
