Ning XSS hole

PoC ->


My Profile -> Account -> City

It's vulnerable in the City field with the vector "><script>alert(document.cookie);</script>

Ning is supposed to be closing it in the next round of patches I believe.

That entire site is absolutely riddled with XSS holes. Any place that allows styled user input (blogs, comments, etc.) allows expression() and -moz-binding.
This vector is what I came up with for comments (Mozilla and IE)...
<a style="x:expression(document.body.firstChild.nextSibling.setAttribute('src',''));-moz-binding:url('')"></a>

a fun exercise in why partial censoring can be dangerous..

spacing comparison can likely uncover more, but i haven't the patience for that ^^
