Security readout for executives and security teams
Plain-English summary
CVE-2014-0762 affects CG Automation ePAQ-9410 Substation Gateway systems using the CG Automation Software DNP3 driver. Bad input validation can force the software into an infinite loop, crash the process, and require a manual restart. The main business risk is loss of gateway availability in operational technology environments.
Executive priority
Treat this as a moderate OT availability risk. It is not reported as actively exploited, but affected substation gateways could require manual recovery after a crash, which can increase operational disruption during incidents or field maintenance windows.
Technical view
The issue is CWE-20 improper input validation in the CG Automation Software DNP3 driver for ePAQ-9410 Substation Gateway products. The CVSS v2 vector is AV:L/AC:M/Au:N/C:N/I:N/A:C, indicating local attack vector, medium complexity, no authentication, and complete availability impact.
Likely exposure
Exposure is most likely in electric utility or substation environments still operating CG Automation ePAQ-9410 Substation Gateway products. The source bundle lists all versions as affected. Systems without this product or DNP3 driver are not indicated as affected.
Exploitation context
The source bundle does not indicate active exploitation, and the CVE is not listed as KEV. The CVSS vector identifies local access as required. The described impact is process crash and manual restart, not data theft or integrity compromise.
Researcher notes
Evidence is limited to the CVE record and CISA advisory references in the bundle. Do not assume remote exploitability, public exploitation, or a specific patch unless confirmed by vendor or CISA guidance. Prioritize asset confirmation and operational impact analysis.
Mitigation direction
- Identify any deployed CG Automation ePAQ-9410 Substation Gateway systems.
- Check CG Automation or CISA guidance for vendor-recommended fixes or mitigations.
- Restrict local and operational access to affected gateway systems.
- Review operational restart procedures for affected substations.
- Monitor affected systems for unexplained DNP3 driver crashes.
Validation and detection
- Confirm whether ePAQ-9410 Substation Gateway products are in asset inventory.
- Verify whether the CG Automation Software DNP3 driver is enabled or used.
- Check system logs for process crashes or manual restart events.
- Validate network and physical access controls around affected gateways.
- Document compensating controls where vendor fixes are unavailable.

Improper Input Validation
Improper Input Validation represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
