AFFECTED PRODUCTS AND SOLUTION
WORKAROUNDS AND MITIGATIONS
Siemens has identified the following specific workarounds and mitigations that customers can apply to reduce the risk:
Apply security hardening of the Windows Server, where the RTLS Locating Manager is installed on, in accordance with your corporate security policies or up-to-date hardening guidelines
Ensure that only trusted persons have access to the system and avoid the configuration of additional local accounts on the 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
SIMATIC RTLS is a real-time wireless locating system for flexible and cost-effective locating solutions. It allows to navigate material flows, control mobile robots, monitor the use of components, and document the assembly of the end product.
The SIMATIC RTLS Locating Manager is used for the configuration, operation, and maintenance of a SIMATIC RTLS installation.
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-2020-10049
The start-stop scripts for the services of the affected application could allow a local attacker to include arbitrary commands that are executed when services are started or stopped interactively by system administrators.
