Summary
ICONICS GENESIS64 and ICONICS Suite contain multiple vulnerabilities including path traversal (CWE-22), unsafe deserialization (CWE-502), and improper input validation (CWE-125) that allow remote code execution. Mitsubishi Electric MC Works64 is also affected. These vulnerabilities can be exploited by a remote attacker without authentication to execute arbitrary code on affected systems.
What this means
What could happen
An attacker could execute arbitrary commands on your HMI/SCADA workstation without credentials, potentially allowing them to modify process setpoints, alter historical data, or disable monitoring and control functions across your plant operations.
Who's at risk
Energy sector operators and plant managers running ICONICS GENESIS64 or ICONICS Suite v10.97/10.97.1 on HMI/SCADA workstations, and those using Mitsubishi Electric MC Works64 or GENESIS32 for real-time process control and monitoring. This affects anyone using these platforms for power distribution, generation, or other critical plant operations.
How it could be exploited
An attacker on the network sends a specially crafted network request to the GENESIS64 or ICONICS Suite application (which listens on a standard port). The request exploits unsafe deserialization or path traversal to execute arbitrary code with the privileges of the application process. If the workstation is part of your operations network, the attacker gains direct access to control logic and plant data.
Prerequisites
- Network access to the GENESIS64 or ICONICS Suite application port
- The affected product version installed and running on a network-accessible workstation
- No special credentials or authentication required
