Summary
SSA-965753: Multiple File Parsing Vulnerabilities in Simcenter Femap and Nastran Before V2512

Notes

Summary
Siemens Simcenter Femap and Nastran is affected by multiple file parsing vulnerabilities that could be triggered when the application reads files in NDB and XDB formats. If a user is tricked to open a malicious file with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution. Siemens has released new versions for the affected products and recommends to update to the latest versions.
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
