			SCO Security Advisory

Subject:		Linux: Webmin Cross-site Scripting and Session ID Spoofing Vulnerabilities 
Advisory number: 	CSSA-2003-002.0
Issue date: 		2003 January 09
Cross reference:
______________________________________________________________________________


1. Problem Description

	From the CVE database:

	Cross-site scripting vulnerability in the authentication page
	for webmin allows remote attackers to insert script into an
	error page and possibly steal cookies.

	Webmin with password timeouts enabled allow local (and
	possibly remote) attackers to bypass authentication and gain
	privileges via certain control characters in the
	authentication information, which can force webmin to accept
	arbitrary username/session ID combinations.


2. Vulnerable Supported Versions

	System				Package
	----------------------------------------------------------------------

	OpenLinux 3.1.1 Server		prior to webmin-0.89-11.i386.rpm

	OpenLinux 3.1.1 Workstation	prior to webmin-0.89-11.i386.rpm

	OpenLinux 3.1 Server		prior to webmin-0.89-11.i386.rpm

	OpenLinux 3.1 Workstation	prior to webmin-0.89-11.i386.rpm


3. Solution

	The proper solution is to install the latest packages. Many
	customers find it easier to use the Caldera System Updater, called
	cupdate (or kcupdate under the KDE environment), to update these
	packages rather than downloading and installing them by hand.
