Google Search Appliance dynamic navigation cross-site scripting vulnerability

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.
