Eric Farraro had discovered an exploit in a little known service from a major web company. It turns out that that exploit is in a little known service called ‘Google Public Service Search’. This service is meant for universities or other non-profit organizations to add a ‘Google’ search to their website.
It differs from the other free Google site search in that it allows you to customize the header and footer of the search results page. It’s interesting to note that the code for your header and footer is actually hosted by Google, on their server.
