CVE-2026-44107

Estado: AplazadaAlta (8.7)—

A reboot of the charging controller can be triggered via Modbus TCP without authentication. Therefore, when the Modbus functionality is enabled by opening the port that CharxModbusServer is listening, an unauthenticated attacker can perform a Denial-of-Service attack.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
