IBM AS400 and iSeries POP3 Server Remote Information Disclosure

This script is Copyright (C) 2005-2011 Tenable Network Security, Inc.

Synopsis :

The remote POP server is affected by an information disclosure

Description :

The remote host appears to be running the POP3 service that comes with
all modern AS/400 and iSeries servers. Further, this service is prone
to an information disclosure vulnerability due to the responses it
provides to username / password combinations. This allows a remote
attacker to determine valid user profiles. Further, the service
offers a means of brute forcing passwords since it does not block a
connection or disable a user after a given number of invalid login

Solution :

Disable the POP3 service if not needed.

Risk factor :

Medium / CVSS Base Score : 5.0
