WORKAROUNDS AND MITIGATIONS
===========================

Siemens has identified the following specific workarounds and mitigations that
customers can apply to reduce the risk:

* The behavior of sorting by non-accessible attributes can be changed by
changing the value of the DataStorage.EnableOrderByEntityAccess custom
runtime setting to true. Starting with version 9.12 it is turned on by
default with the new, improved behavior.


Product specific remediations or mitigations can be found in the section
"Affected Products and Solution".

Please follow the "General Security Recommendations".


GENERAL SECURITY RECOMMENDATIONS
================================

As a general security measure, Siemens strongly recommends to protect
network access to devices with appropriate mechanisms. In order to
operate the devices in a protected IT environment, Siemens recommends to
configure the environment according to Siemens' operational guidelines
for Industrial Security (Download:
https://www.siemens.com/cert/operational-guidelines-industrial-security),
and to follow the recommendations in the product manuals.

PRODUCT DESCRIPTION
===================

Mendix is a high productivity app platform that enables you to build and
continuously improve mobile and web applications at scale. The Mendix
Platform is designed to accelerate enterprise app delivery across your
entire application development lifecycle, from ideation to deployment
and operations.

VULNERABILITY CLASSIFICATION
============================

The vulnerability classification has been performed by using the CVSS scoring
system in version 3.1 (CVSS v3.1) (https://www.first.org/cvss/). The CVSS
environmental score is specific to the customer's environment and will impact
the overall CVSS score. The environmental score should therefore be
individually defined by the customer to accomplish final scoring.

An additional classification has been performed using the CWE classification, a
community-developed list of common software security weaknesses. This serves as
a common language and as a baseline for weakness identification, mitigation,
and prevention efforts. A detailed list of CWE classes can be found at:
https://cwe.mitre.org/.



* Vulnerability CVE-2022-25650
