Synopsis
========

Webmin and Usermin are vulnerable to an arbitrary file disclosure
through a specially crafted URL.

Background
==========

Webmin is a web-based interface for Unix-like systems. Usermin is a
simplified version of Webmin designed for use by normal users rather
than system administrators.

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

    -------------------------------------------------------------------
     2 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

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

A vulnerability in both Webmin and Usermin has been discovered by Kenny
Chen, wherein simplify_path is called before the HTML is decoded.

Impact
======

A non-authenticated user can read any file on the server using a
specially crafted URL.

Workaround
==========

For a temporary workaround, IP Access Control can be setup on Webmin
and Usermin.

Resolution
==========

All Webmin users should update to the latest stable version:

    # emerge --sync
    # emerge --ask --verbose --oneshot ">=app-admin/webmin-1.290"

All Usermin users should update to the latest stable version:

    # emerge --sync
    # emerge --ask --verbose --oneshot ">=app-admin/usermin-1.220"
