This vulnerability may allow a remote attacker to read or modify data in web pages. I. Description Google Mini and Google Search Appliance fail to properly handle UTF-7 encoded URIs, possibly allowing a remote attacker to inject arbitrary content, including script. II. Impact A remote, unauthenticated attacker may be able to read or modify data in web pages and web page related resources, such as cookies. III. Solution Apply a Workaround Google has provided workarounds for their customers. For Google Mini, M2-series and MID-series see Google Advisory ga-2006-11-m (requires customer login). For Google Search Appliance, all models, see Google Advisory ga-2006-11-g (requires customer login). Disable scripting Disable scripting in your web browser, as specified in the Securing Your Web Browser document and the Malicious Web Scripts FAQ. Do not follow unsolicited links In order to convince users to visit their sites, attackers often use URL encoding, IP address variations, long URLs, intentional misspellings, and other techniques to create misleading links. Do not click on unsolicited links received in email, instant messages, web forums, or internet relay chat (IRC) channels. Type URLs directly into the browser to avoid these misleading links. While these are generally good security practices, following these behaviors will not prevent exploitation of this vulnerability in all cases, particularly if a trusted site has been compromised or allows cross-site scripting.
