A vulnerability has been identified in SIMATIC NET PC Software V14 (All versions), SIMATIC NET PC Software V15 (All versions), SIMATIC PCS 7 V8.2 (All versions), SIMATIC PCS 7 V9.0 (All versions), SIMATIC PCS 7 V9.1 (All versions), SIMATIC WinCC (All versions < V8.0), SINAUT Software ST7sc (All versions). Before SIMATIC WinCC V8, legacy OPC services (OPC DA (Data Access), OPC HDA (Historical Data Access), and OPC AE (Alarms & Events)) were used per default. These services were designed on top of the Windows ActiveX and DCOM mechanisms and do not implement state-of-the-art security mechanisms for authentication and encryption of contents.

  • SSA-508677SSA-508677: Use of Obsolete Function Vulnerability in SIMATIC WinCC before V82023-06-13csaf · siemens_psirtDE

    Before SIMATIC WinCC V8, legacy OPC services (OPC DA (Data Access), OPC HDA (Historical Data Access), and OPC AE (Alarms & Events)) were used per default. These services were designed on top of the Windows ActiveX and DCOM mechanisms and do not implement state-of-the-art security mechanisms for authentication and encryption of contents. Starting with WinCC V8.0 the legacy OPC services are no longer enabled by default in new installations. Siemens recommends to use OPC UA instead and to disable the legacy OPC services. For deployments where the legacy OPC services are still in use, ensure that only trusted users are part of the SIMATIC HMI group.
