7-Technologies Interactive Graphical SCADA

Low RiskICS-CERT ICSA-11-353-01Sep 21, 2011
Summary

7-Technologies Interactive Graphical SCADA System contains a code validation vulnerability (CWE-427) in versions prior to 9.0.0.11291 that could allow remote code execution. The vulnerability relates to improper validation of code or search paths, potentially permitting an attacker to execute arbitrary code with application privileges. This affects the integrity and availability of SCADA operations in energy sector environments.

What this means
What could happen
An attacker with network access to the SCADA system could execute arbitrary code with the privileges of the application, potentially allowing them to modify process parameters, alter historical data, or disrupt control operations.
Who's at risk
Energy sector organizations using 7-Technologies Interactive Graphical SCADA System for power generation, distribution, or grid management. Any facility that uses this SCADA software to monitor and control critical infrastructure equipment is affected.
How it could be exploited
An attacker would exploit a code validation vulnerability (CWE-427: untrusted search path or similar) to inject malicious code that executes with SCADA application privileges. This could be triggered through a network-accessible interface if the SCADA system is reachable on the network.
Prerequisites
  • Network access to the Interactive Graphical SCADA System application port
  • System running Interactive Graphical SCADA version prior to 9.0.0.11291

0/2
Interactive Graphical SCADA System: <V9.0.0.11291 has reached End of Life. The vendor will not release a patch. Apply the following compensating controls:
HARDENINGImplement network segmentation to restrict access to the SCADA system—allow only authorized engineering workstations and control devices to communicate with the system
HARDENINGMonitor SCADA system logs for unexpected code execution or process parameter changes
