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>
