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

2 app-admin/usermin < 1.220 >= 1.220
-------------------------------------------------------------------
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"
