CVE-2006-3549


Description:
Moritz Naumann has reported some vulnerabilities in Horde, which be exploited by malicious people to conduct cross-site scripting attacks.

Input passed to the "url" parameter in go.php, the "module" parameter in help/, and the "name" parameter in problem.php isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Examples:
http://[host]/services/go.php?url=http://./;URL=javascript:[code]
http://[host]/services/help/?show=about&module=%3Cmeta%20http-equiv=%22refresh%22%20content=%220;URL=javascript:[code]
http://services/problem.php?name=[code]

Successful exploitation of the go.php script requires that the user is using the Microsoft Internet Explorer 6 browser.

The vulnerabilities have been reported in versions 3.0.0 through 3.0.10, and 3.1.0 through 3.1.1. Prior versions may also be affected.

Solution:
Update to version 3.0.11 or 3.1.2:
http://ftp.horde.org/pub/horde/horde-3.0.11.tar.gz
http://ftp.horde.org/pub/horde/horde-3.1.2.tar.gz
