The MOD3 command traffic between the monitoring application and the inverter is transmitted in plaintext without encryption or obfuscation. This vulnerability may allow an attacker with access to a local network to intercept, manipulate, replay, or forge critical data, including read/write operations for voltage, current, and power configuration, operational status, alarms, telemetry, system reset, or inverter control commands, potentially disrupting power generation or reconfiguring inverter settings.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.9, requiring local system access to exploit but requires specific conditions to be met without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and limited availability for affected systems.
Reported in 2025, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For affected software, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
