Summary
SSA-983548: Multiple SPP File Parsing Vulnerabilities in Tecnomatix Plant Simulation

Notes

Summary
Siemens Tecnomatix Plant Simulation has released an update for version V16.0 that fixes multiple vulnerabilities that could be triggered when the application reads SPP files. If a user is tricked to open a malicious file using the affected application, this could lead to a crash, and potentially also to arbitrary code execution or data extraction on the target host system. Siemens recommends to update to the latest version and to avoid opening of untrusted files from unknown sources.
General 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. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity
