Yes a XSS post again. I’m sorry
I’ve been having fun testing some really good filters (some of the best in the business IMO). I found a vector that isn’t on rsnake’s cheat sheet. Check it out:-
Only works on IE
<isindex type=image src=1 onerror=alert(1)>
Because IE treats the isindex element (a very old html element) as a input tag you can specify the same attributes and execute javascript.
Update…Found another variation which is pretty cool:-
<isindex action=javascript:alert(1) type=image>
