Many sites allow you to use html tags viz in Guestbooks, feedbacks, topsites etc. This can easily be exploited to redirect the entire webpage to whatever site/page you want.

Proof of concept:

Sign up for a topsites where you are allowed to use html tags in site description & use the followeing tag:

<meta http-equiv="refresh" content="1;URL=http://harry-inc.com"> to redirect the entire page to your site Wink

Solution: Disable HTML tags

Harder way is to allow some html tags, like <b>, <u>, etc.
But this needs bulletproof sanitizing code Smile
