Schneider Electric is aware of multiple vulnerabilities in the Interactive Graphical SCADA System (IGSS) product. The IGSS product is a state-of-the art SCADA system used for monitoring and controlling industrial processes. IGSS communicates with all major industry standard PLC drivers. Failure to apply the remediations provided below may risk remote code execution, which could result in an attacker gaining access to the Windows Operating System on the machine used to import CGF files, typically a step performed during system design time.
