mantis -- "view_filters_page.php" cross site scripting vulnerability

r0t reports:

Mantis contains a flaw that allows a remote cross site scripting attack. This flaw exists because input passed to "target_field" parameter in "view_filters_page.php" is not properly sanitised before being returned to the user. 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.
