Synopsis

The Horde Application Framework is vulnerable to a cross-site scripting vulnerability which could lead to the compromise of the victim's browser content.

2. Impact Information

Background

The Horde Application Framework is a general-purpose web application framework written in PHP, providing classes for handling preferences, compression, browser detection, connection tracking, MIME, and more.

Description

The Horde Team reported a potential XSS vulnerability. Horde fails to properly escape error messages which may lead to displaying unsanitized error messages via Notification_Listener::getMessage()

Impact

By enticing a user to read a specially-crafted e-mail or using a manipulated URL, an attacker can execute arbitrary scripts running in the context of the victim's browser. This could lead to a compromise of the user's browser content.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All Horde Application Framework users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/horde-2.2.9"
