Qpopper PAM Authentication Error Message User Name Enumeration
Remote / Network Access Authentication Management
Loss of Confidentiality
Exploit Public

- 漏洞描述

Qpopper contains a flaw that may allow a malicious user to get unauthorized information. The issue is due to different error messages being output when authentication attempts are made using valid and invalid usernames. When qpopper is used in conjunction with PAM, remote attackers can enumerate valid account usernames, resulting in a loss of confidentiality.

- 漏洞讨论

Qpopper is a widely used POP daemon for Unix systems.

When qpopper is used in conjunction with PAM on Red Hat systems, remote attackers can enumerate valid account usernames. This is due to different error messages being output when authentication attempts are made using valid and invalid usernames.

This information may make a brute force attack significantly more feasible.

Note: This vulnerability only affects qpopper when it is used with PAM. Red Hat systems are reported to be vulnerable.

- 漏洞利用

There is no exploit required.
