Google Search Appliance dynamic navigation cross-site scripting vulnerability

Original Release date: 01 May 2014 | Last revised: 01 May 2014

Overview

Google Search Appliance (GSA) devices contain a cross-site scripting (XSS) vulnerability when dynamic navigation is enabled.

Description

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Google Search Appliance versions earlier than 7.2.0.G.114 and 7.0.14.G.216 fail to properly sanitize user input that is reflected directly into a JavaScript <script> block if the dynamic navigation feature is enabled. This allows an attacker to perform a reflected XSS attack.

Impact

A remote unauthenticated attacker may be able to execute arbitrary script in the context of the end-user's browser session.

Solution

Apply an update

This issue is resolved in GSA versions 7.2.0.G.114 and 7.0.14.G.216. These updates are available in the Google Enterprise Support Portal.

Disable dynamic navigation

This vulnerability can be mitigated by disabling the dynamic navigation feature in the GSA.
