Hi Steve, Josh, vendors, list.

The researchers adamziaja, Devilshakerz, DingjieYang and me found multiple
stored XSS-vulnerabilities in the administrative backend of CMS MyBB v.
1.8.3.

The stored XSS-vulnerabilities can be found in different modules in the
following locations of a common MyBB installation:

======================
Module "config-attachment_types"
======================

http://{TARGET}/admin/index.php?module=config-attachment_types&action=add

executed in: e.g. http://
{TARGET}/admin/index.php?module=config-attachment_types

===============
Module "config-mycode"
===============

via form fields "title" and "short description":

http://{TARGET}/admin/index.php?module=config-mycode&action=add

executed in: e.g. http://{TARGET}/admin/index.php?module=config-mycode

===================
Module "forum-management"

====================================

via form field "title":

http://
{TARGET}/admin/index.php?module=style-templates&action=add_template_group

executed in: e.g. http://
{TARGET}/admin/index.php?module=style-templates&sid={TEMPLATES_NUMERIC_ID}

=============
Module "tool-tasks"
=============

via form field "title":

http://{TARGET}/admin/index.php?module=tools-tasks&action=add
