The SIMATIC RF Manager uses an ActiveX component. Vulnerability Characterization Vulnerability Overview Buffer Overflow 1 Siemens is a German-based company that maintains offices in several countries around the world. ERP and MES are widely used in industrial environments such as critical manufacturing, health and healthcare, power generation and distribution, food and beverage, and chemical industries worldwide. This includes collecting supplied data, and compressing this data for enterprise systems, such as the Enterprise Resource Management (ERP) layer and Manufacturing Execution Systems (MES) layer. Products in the Siemens SIMATIC RF Manager family manage connected radio frequency identification (RFID) readers to SIMATIC S7 controllers. ICS-CERT recommends that organizations evaluate the impact of this vulnerability based on their operational environment, architecture, and product implementation. Impact to individual organizations depends on many factors that are unique to each organization. This could impact the setup of systems in the critical manufacturing, health and healthcare, power generation and distribution, food and beverage, and chemical industries. By exploiting this vulnerability, an attacker could execute remote code and could cause a denial of service of the RF Manager.
