Vuln. Description:
Input passed to the "q" parameter in "search.asp" isn't 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.

example:
/search.asp?q=%3Cscript%3Ealert%28%27r0t%27%29%3C%2Fscript%3E&c=&a.x=21&a.y=11

Solution:
Edit the source code to ensure that input is properly sanitised.
