<title>Webmin, Usermin: Remote code execution through PAM authentication</title>
|
|
<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.

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.

|
|
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.
|
|
</p>
|
|
</description>
|
|
<impact type="high">
|
|
<p>
|
|
A remote attacker could bypass the authentication process and run
|
|
any command as the root user on the target server.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Do not enable "full PAM conversations" in the Authentication
|
|
options of Webmin and Usermin.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Webmin users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-admin/webmin-1.230"</code>
|
|
<p>
|
|
All Usermin users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-admin/usermin-1.160"</code>
|
|
</resolution>
