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:, and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at:

The vulnerability classification has been performed by using the CVSS scoring system in version 3.1 (CVSS v3.1) ( 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:

CVSS v3.1 Base Score 8.2
CWE CWE-73: External Control of File Name or Path
CVSS v3.1 Base Score 7.7
CWE CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
