Summary
SSA-133038: Multiple Modfem File Parsing Vulnerabilities in Simcenter Femap

Notes

Summary
Siemens Simcenter Femap is affected by two vulnerabilities that could be triggered when the application reads modfem files. If a user is tricked to open a malicious file with 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 has released updates for Simcenter Femap and recommends to update to the latest version to fix the vulnerabilities. Siemens recommends 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
