Affected pages:
----------------------------------------------
1. http://netscape.com
2. http://search.netscape.com
3. http://channels.netscape.com

Vulnerability:
----------------------------------------------
I found a bug in the search boxes of the Netscape Network.
If you type in a "searchword" into the searchbox of "http://netscape.com" or "http://channels.netscape.com"
you'll be automaticly redirected to "http://search.netscape.com" and you'll see the results of your search.

Input passed to the "query" parameter in "search?"-file is not properly sanitised before being returned to the user. 
This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Sending a malicious code will result a code working on the page that pops up...

http://search.netscape.com/ns/search?query=<script>alert("MajorSecurity")</script>

Example:
----------------------------------------------
http://search.netscape.com/ns/search?query=<script>alert("MajorSecurity")</script>
