WordPress WP Forum Server "groupid" Cross-Site Scripting Vulnerability


Description   A vulnerability has been discovered in the WP Forum Server plugin for WordPress, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed to the "groupid" parameter in wp-admin/admin.php (when "page" is set to "forum-server/fs-admin/fs-admin.php", "vasthtml_action" is set to "structure", and "do" is set to "addforum") 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.
