Input passed via the "ajax_action" parameter to wp-content/plugins/placester/admin/support_ajax.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. The vulnerability is confirmed in version 0.1.0. Other versions may also be affected. SOLUTION: Edit the source code to ensure that input is properly sanitised. PROVIDED AND/OR DISCOVERED BY: John Leitch, AutoSec Tools.
