** DISPUTED ** Microsoft Internet Explorer 6 executes web script from URIs of arbitrary scheme names ending with the \script\ character sequence using the (1) vbscript: handler for scheme names with 7 through 9 characters and the (2) javascript: handler for scheme names with 10 or more characters which might allow remote attackers to bypass certain XSS protection schemes. NOTE: other researchers dispute the significance of this issue stating \this only works when typed in the address bar.\
