Vulnerability:

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

I found a bug in the search-engine of Hotbot("http://hotbot.com").

Input passed to the "query" parameter in "index.php" 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://hotbot.com/index.php?query=[XSS CODE HERE]

Examples:

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

/index.php?query=<script>alert("MajorSecurity")</script>

/index.php?query=3Cscript%3Ealert(document.cookie)%3C/script%3E
