Description

ExtCalendar contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'year', 'month', 'next' or 'prev' variables upon submission to the calendar.php script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
