Summary
SSA-818688: Multiple Vulnerabilities in Solid Edge before SE2021MP7
Notes
Summary
Siemens has released a new version for Solid Edge that fixes three vulnerabilities - an XML external entity (XXE) injection, and two file parsing issues which could be triggered when the application reads OBJ files.
If a user is tricked to opening a malicious file using the affected application this could lead the application to crash, or potentially arbitrary code execution and data extraction on the target host system.
Siemens recommends to update to the latest version and to limit opening of files from unknown sources in the affected products.
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.
