US-CERT Vulnerability Note VU#615857
Google Desktop vulnerable to to cross-site scripting
Overview
A cross-site scripting vulnerability exists in the Google
Desktop Search application. This vulnerability may allow an
attacker to take any action on a vulnerable system that the
Google Desktop Search can.
I. Description
Google Desktop Search is a desktop search program that is integrated
into the Google search engine. Google Desktop Search indexes the
user's local hard drive, and allows the results to be searched from
a browser.
The Google Desktop Search program contains a cross-site scripting
vulnerability in the under parameter. This vulnerability occurs because
the Google Desktop Search engine fails to properly sanitize user input.
Note that this vulnerability may not be exploited remotely without
the presence of another vulnerability.
II. Impact
A remote unauthenticated attacker may be able to perform any action
that the Google Desktop Search engine is capable of performing. This
includes executing programs that are already on a vulnerable system,
searching and viewing files and exfiltrating sensitive data.
III. Solution
Upgrade
Google has addressed this issue in the most recent version of the
Google Desktop Search. Note that Google updates the Google Desktop
Search automatically.
Disable JavaScript
Disable JavaScript in your browser's preferences. Instructions for
disabling JavaScript can be found in the Securing Your Web Browser
document and the Malicious Web Scripts FAQ. Some Mozilla add-ons can
simplify the ability to enable or disable JavaScript, or set up
site-specific rules for doing so.
