Vulnerability from csaf_siemens - Published: 2021-03-09 00:00 - Updated: 2021-04-13 00:00
Summary
SSA-715184: Multiple File Parsing Vulnerabilities in Solid Edge

Notes

Summary
Siemens has released new versions for Solid Edge to fix multiple vulnerabilities that could be triggered when the application reads files in different file formats (PAR, DFT, XML extensions). 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 recommends to update to the latest version and to avoid opening of untrusted files from unknown sources. Please refer to SSA-574442 for further information regarding latest version update.
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
