Summary
SSA-365397: Multiple File Parsing Vulnerabilities in JT2Go and Teamcenter Visualization before V13.2.0.1

Notes

Summary
Siemens has released version V13.2.0.1 for JT2Go and Teamcenter Visualization to fix multiple vulnerabilities that could be triggered when the products read files in different file formats (CGM, DGN, DXF, and DWG). If a user is tricked to open a malicious file with the affected products, this could lead the application to crash or potentially arbitrary code execution. Siemens recommends to update to the latest versions and to limit opening of untrusted files from unknown sources in the affected products. Note: - This advisory also covers security vulnerabilities recently disclosed by Open Design Alliance [0] [0] https://www.opendesign.com/security-advisories
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
