- 漏洞讨论

IBM iSeries AS400 computers are reported prone to a remote information disclosure vulnerability. The issue exists in the POP3 service that is installed and runs by default on affected computers.

During authentication when a username is supplied the affected service will reply with overly verbose status messages.

A remote attacker may employ these status messages to aid in the disclosure of valid usernames during brute force attacks. Information that is harvested in this manner may then be used to aid in further attacks.

- 漏洞利用

No exploit is required.
