Summary
SSA-042050: Know-How Protection Mechanism Failure in TIA Portal

Notes

Summary
The know-how protection feature in Totally Integrated Automation Portal (TIA Portal) does not properly update the encryption of existing program blocks when a project file is updated. This could allow attackers with access to the project file to recover previous - yet unprotected - versions of the project without the knowledge of the know-how protection password. Siemens is preparing fix versions and recommends countermeasures for products where fixes are not, or not yet available.
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
