GE Proficy HMI/SCADA CIMPLICITY WebView Improper Input Validation
Low RiskICS-CERT ICSA-13-170-01Mar 22, 2013
Summary
GE Proficy HMI/SCADA CIMPLICITY versions 4.01 through 8.1 and all versions of Proficy Process Systems with CIMPLICITY contain improper input validation in the WebView component. The validation bypass could allow remote injection of code or commands into the HMI environment, compromising monitoring and control operations. No vendor fix is available for this vulnerability.
What this means
What could happen
Improper input validation in the WebView component allows attackers to inject malicious code or commands, potentially compromising the integrity of HMI operations and enabling unauthorized control of monitored systems.
Who's at risk
Energy utilities and manufacturing plants using GE Proficy HMI/SCADA CIMPLICITY for process monitoring and control should be concerned. This affects operators relying on the WebView interface for remote monitoring or supervisory functions in power generation and industrial automation environments.
How it could be exploited
An attacker with network access to the WebView interface could submit specially crafted input that bypasses validation checks, injecting code or commands that the HMI processes without proper sanitization. This could lead to unauthorized actions in the monitored SCADA environment.
Prerequisites
- Network access to the CIMPLICITY WebView interface
- Ability to submit crafted input to a vulnerable form or parameter
- No authentication explicitly required based on advisory

Remediation & Mitigation
0/5
Do now
0/2WORKAROUNDRestrict network access to the CIMPLICITY WebView interface using firewall rules, limiting exposure to trusted engineering and operations networks only
WORKAROUNDDisable WebView functionality if not required for operations
Schedule — requires maintenance window
0/2Patching may require device reboot — plan for process interruption
HARDENINGDeploy input validation controls at the network perimeter to filter malicious payloads before they reach the HMI
HARDENINGMonitor WebView access logs for suspicious input patterns or failed validation attempts
