CVE-2023-28829 is a high-severity vulnerability (CVSS 8.8) affecting Siemens SIMATIC NET PC Software, SIMATIC PCS 7, SIMATIC WinCC (versions prior to V8.0), and SINAUT Software ST7sc. The flaw stems from the use of legacy OPC services (DA, HDA, AE) that lack modern authentication and encryption, making them susceptible to compromise. An authenticated attacker can exploit this remotely with low complexity, leading to high impact on confidentiality, integrity, and availability. Currently, there is no evidence of active exploitation, public exploit code, or significant community discussion.
