Spiders, title tag parsing, XSS
Posted by: Ivan

Hello everyone,

I put some html pages on my website with special title tag, with hope that I will find some vulns in some spiders. As I know, spiders doesn`t use urls from title tag, in order to spider that pages ?

Anyway, that title tags look like this:

1. <script>window.location = "someurl"</script>
2. <img src="javascript:window.location = 'someurl'">
3. window.location = 'someurl'
4. /img src="javascript:window.location = 'someurl"/

And, two spiders (MSN and accoonabot) visit "someurl", accoonabot with refer from .html page and MSN without any refer. Both of them came from 1st case of title tag.

I`m asking now, is there some vulns in spiders parsing engine ? Is accoonabot redirected with javascript because there is refer or MSN have some vuln in displaying title tag in their "backend" system ?

I now that this test can be better, but I want to hear first yours opinion ...

there can of course be vulns in spiders parsing engine. and the thought of a attacker controlled major search engine spider is quite chilling...

although without getting our dirty little hands on a spider binary it will prove quite difficult to validate even the simplest buffer overflow.


Those that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.

Ok, I know that is hard to validate vuln in spiders but I try this, and I just think that somebody of you have some similar experience ...
