GLSA 200707-05: Webmin, Usermin: Cross-site scripting vulnerabilities

http://security.gentoo.org/

Severity:	low
Title:	Webmin, Usermin: Cross-site scripting vulnerabilities
Date:	07/05/2007
Bugs:	#181385
ID:	200707-05

Synopsis

Webmin and Usermin are vulnerable to cross-site scripting vulnerabilities (XSS).

Background

Webmin is a web-based administrative 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	< 1.350	>= 1.350	All supported architectures
app-admin/usermin	< 1.280	>= 1.280	All supported architectures

Description

The pam_login.cgi file does not properly sanitize user input before sending it back as output to the user.

Impact

An unauthenticated attacker could entice a user to browse a specially crafted URL, allowing for the execution of script code in the context of the user's browser and for the theft of browser credentials. This may permit the attacker to login to Webmin or Usermin with the user's permissions.

Workaround

There is no known workaround at this time.

Resolution

All Webmin users should update to the latest stable version:

    # emerge --sync
    # emerge --ask --verbose --oneshot ">=app-admin/webmin-1.350"

All Usermin users should update to the latest stable version:


    # emerge --sync
    # emerge --ask --verbose --oneshot ">=app-admin/usermin-1.280"
