  • SSA-042050SSA-042050: Know-How Protection Mechanism Failure in TIA Portal2023-06-13csaf · siemens_psirtDE

    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 recommends specific countermeasures for products where fixes are not, or not yet available.
