What is CVE-2023-28829?

A significant vulnerability exists in Siemens' SIMATIC NET PC Software and PCS 7 Software, affecting various versions of these products. The issue arises from the use of legacy OPC services (including OPC DA, OPC HDA, and OPC AE), which were default settings prior to the release of SIMATIC WinCC V8. These services rely on the outdated Windows ActiveX and DCOM technologies, lacking modern security measures for authentication and data encryption. This oversight leaves systems at risk of unauthorized access and potential data breaches.
