Current Version:         1.0
CVSS v3.1 Base Score:    4.2

SUMMARY
=======

SINEMA Remote Connect Server is missing HTTP security headers on the web
server. This could aid attackers by making the servers more prone to
clickjacking, channel downgrade attacks and other similar client-based
attack vectors.

Siemens has released an update for the SINEMA Remote Connect Server and
recommends to update to the latest version.


AFFECTED PRODUCTS AND SOLUTION
==============================


* SINEMA Remote Connect Server

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

SINEMA Remote Connect is a management platform for remote networks that
enables the simple management of tunnel connections (VPN) between
headquarters, service technicians, and installed machines or plants. It
provides both the Remote Connect Server, which is the server
application, and the Remote Connect Client, which is an OpenVPN client
for optimal connection to SINEMA Remote Connect Server.

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/.
