webcrawler.com - Cross site scripting vulnerability
----------------------------------------------
Type: Cross site scripting

Date: June, 13th 2006

Vulnerability:
----------------------------------------------
I found a bug in the search-engine of Webcrawler("http://webcrawler.com").
It is vulnerable for cross site scripting.

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

http://msxml.webcrawler.com/info.wbcrwl/search/web/[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.

Example:
----------------------------------------------
/info.wbcrwl/search/web/<script>alert("MajorSecurity")</script>
