IBM AS400 and iSeries POP3 Server Remote Information Disclosure Vulnerability

Vulnerability Assessment Summary
Checks for remote information disclosure vulnerability in IBM AS400 and iSeries POP3 server

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote POP server is affected by a information disclosure
vulnerability.

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 permits a remote
attacker to acertain 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
attempts.
