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.
This vulnerability carries a LOW severity rating with a CVSS v3.1 score of 3.9, indicating it requires adjacent network access but requires specific conditions to be met without requiring user interaction . The vulnerability impacts limited data confidentiality, limited integrity, and limited availability for affected systems. Impacting 4 products from siemens, from siemens, from siemens and 1 other, organizations running these solutions should prioritize assessment and patching.
Reported in 2023, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For siemens's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
