Cisco.com XSS Vulnerability Found

A few days back , I have read about a Cross-Site-Scripting vulnerability in cisco's search engine. this vulnerability enables a hacker to use the cisco.com website for phishing purposes and for "man-in-the-browser" attacks.

With the code ( posted as a link ) following , one could send a user to cisco's website and bounce off to his own bogus machine. i did not check for any further enrichments of this exploit , but it seems strange that this kind of thing could come out on a website that is as secure as cisco.com. I really believe that there are Application Layer Firewalls defending cisco's website, and if there are any - are they misconfigured ?

I have reported this vulnerability to a friend of mine at cisco's security proffesional services team in EMEA , and i hope this will soon be fixed.

Here is the POC code :

http://cisco.com/pcgi-bin/search/search.pl?searchPhrase=%27+onmouseover%3D%22location.href%3D%28%27http%3A%2F%2Fwww.cnn.com%27%29%22+value%3D%27&x=20&y=15&accessLevel=Guest&language=en&country=US&Search+All+Cisco.com=cisco.com

Notice that the code bounces you to www.cnn.com website , but anything can be put here. which makes you wonder ...

Anyway, I cannot give credit to this code to any specific Hacker\Hacking Group because i have seen a similar code at more than one of my resources , each from a different country . strangely enough - they all came out in the same 24 hours. script kiddies ?

As i was promised by my cisco friend - this is not a light weighted issue for a company of that size , and i believe that the fix will come very soon.
