[原文]miniserv.pl in Webmin before 1.230 and Usermin before 1.160, when "full PAM conversations" is enabled, allows remote attackers to bypass authentication by spoofing session IDs via certain metacharacters (line feed or carriage return).


[CNNVD]Webmin/Usermin远程PAM认证绕过漏洞(CNNVD-200509-220)

        Webmin是一款基于WEB的Unix和Linux操作系统系统管理接口;Usermin则设计用于操作用户级别的任务,允许Unix系统中用户简单的进行接收邮件、执行SSH和邮件转发配置。
        Webmin和Usermin中存在远程PAM认证绕过漏洞。如果Usermin或Webmin配置模块启用了"Support full PAM conversations?"选项的话,就可能允许远程攻击者绕过认证,完全控制受影响的系统。

Gentoo Linux Security Advisory GLSA 200509-17 - Keigo Yamazaki discovered that the miniserv.pl webserver, used in both Webmin and Usermin, does not properly validate authentication credentials before sending them to the PAM (Pluggable Authentication Modules) authentication process. The default configuration shipped with Gentoo does not enable the full PAM conversations option and is therefore unaffected by this flaw. Versions less than 1.230 are affected.

Synopsis
========

If Webmin or Usermin is configured to use full PAM conversations, it is
vulnerable to the remote execution of arbitrary code with root
privileges.

Background
==========

Webmin and Usermin are web-based system administration consoles. Webmin
allows an administrator to easily configure servers and other features.
Usermin allows users to configure their own accounts, execute commands,
and read e-mails.

Affected packages
=================

    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------

  2  app-admin/usermin       < 1.160                          >= 1.160
    -------------------------------------------------------------------
     2 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

Description
===========

Keigo Yamazaki discovered that the miniserv.pl webserver, used in both
Webmin and Usermin, does not properly validate authentication
credentials before sending them to the PAM (Pluggable Authentication
Modules) authentication process. The default configuration shipped with
Gentoo does not enable the "full PAM conversations" option and is
therefore unaffected by this flaw.

Impact
======

A remote attacker could bypass the authentication process and run any
command as the root user on the target server.

Workaround
==========

Do not enable "full PAM conversations" in the Authentication options of
Webmin and Usermin.

Resolution
==========

All Webmin users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-admin/webmin-1.230"

All Usermin users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-admin/usermin-1.160"

- 漏洞讨论

Webmin and Usermin are susceptible to a remote PAM authentication bypass vulnerability. This issue is present in the 'miniserv.pl' Web server that is bundled with these applications.

Due to insufficient input validation, shell metacharacters may be employed to bypass the authentication mechanism.

Due to the nature of these applications, full system compromise is very likely after gaining access.

- 漏洞利用

An exploit is not required.

- 解决方案

The vendor has released updated versions of the affected packages to address this issue.

Gentoo has released advisory GLSA 200509-17 to address these issues. Please see the referenced advisory for more information. Gentoo users may carry out the following commands to update their computers:

All Webmin users:

emerge --sync
emerge --ask --oneshot --verbose ">=app-admin/webmin-1.230"

All Usermin users:

emerge --sync
emerge --ask --oneshot --verbose ">=app-admin/usermin-1.160"

Mandriva has released advisory MDKSA-2005:176 to address this issue. Please see the referenced advisory for further information.

SUSE Linux has released security advisory SUSE-SR:2005:024 addressing this issue. Please see the referenced advisory for details on obtaining and applying the appropriate updates.
