Date:	08/06/2006

ID:	200608-11

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	Architecture(s)
app-admin/webmin	< 1.290	>= 1.290	All supported architectures
app-admin/usermin	< 1.220	>= 1.220	All 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"
