ComplexityLow
User InteractionNone needed
Summary
Hitachi Energy Gateway Station versions 3.0.0.0 through 3.2.0.0 contain input validation (CWE-20) and buffer handling (CWE-120) flaws that allow remote attackers to cause service crashes, prevent the application from starting, or execute arbitrary scripts without authentication. Successful exploitation disrupts Gateway Station operation, which manages critical energy system communications and monitoring. The vulnerabilities are remotely exploitable with low attack complexity.
What this means
What could happen
An attacker could remotely cause parts of the Gateway Station to fail to start, execute unauthorized scripts on the device, or crash the service entirely, disrupting critical energy management operations.
Who's at risk
Energy utilities and power system operators who use Hitachi Energy Gateway Station for grid management and monitoring. This affects anyone managing distributed energy resources, substations, or SCADA integration points that rely on this gateway appliance.
How it could be exploited
An attacker on the network can send a crafted request to the Gateway Station service. Because the device does not properly validate input (CWE-20) and has buffer handling issues (CWE-120), the malformed input triggers a crash, service failure, or script execution without any credentials needed.
Prerequisites
- Network access to the Gateway Station service port
- No authentication required
- No special configuration required
