A vulnerability has been identified in OpenPCS 7 V9.1 (All versions < V9.1 SP2 UC05), SIMATIC BATCH V9.1 (All versions < V9.1 SP2 UC05), SIMATIC PCS 7 V9.1 (All versions < V9.1 SP2 UC05), SIMATIC Route Control V9.1 (All versions < V9.1 SP2 UC05), SIMATIC WinCC Runtime Professional V18 (All versions < V18 Update 4), SIMATIC WinCC Runtime Professional V19 (All versions < V19 Update 2), SIMATIC WinCC V7.4 (All versions), SIMATIC WinCC V7.5 (All versions < V7.5 SP2 Update 15), SIMATIC WinCC V8.0 (All versions < V8.0 Update 4). The implementation of the RPC (Remote Procedure call) communication protocol in the affected products do not properly handle certain unorganized RPC messages. An attacker could use this vulnerability to cause a denial of service condition in the RPC server.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.5, indicating it requires adjacent network access with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts and availability (service disruption) for affected systems. Impacting 6 products from siemens, from siemens, from siemens and 3 others, organizations running these solutions should prioritize assessment and patching.
Reported in 2024, 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.
