The script /iissamples/sdk/asp/interaction/Form_JScript.asp 
(or Form_VBScript.asp) allows you to insert information into a form 
field and once submitted re-displays the page, printing the text you entered.  
This .asp doesn't perform any input validation, and hence you can input a 
string like:
<SCRIPT>alert(document.domain)</SCRIPT>.

More information on cross-site scripting attacks can be found at:

http://www.cert.org/advisories/CA-2000-02.html

Solution: Always remove sample applications from productions servers. 
In this case, remove the entire /iissamples folder.
Risk factor : Low";
