CVE-2026-9037
A firmware update mechanism in the affected charging controller fails to validate the authenticity of firmware packages delivered through the device's management interface. Because cryptographic signatures are not verified, an attacker with the ability to interfere with or impersonate the management channel could cause the device to install an unauthorized firmware package. This condition could allow execution of unauthorized code with high privileges on the device.

- Puntuación base: 9.3
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.27%
- Percentil entre todas las CVEs puntuadas: 17
- Fecha de la puntuación: 6/10/2026
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.
- Explotación
T1195Supply Chain Compromiseinitial access85 % - Impacto principal
T1195.002Compromise Software Supply Chaininitial access85 % - Impacto secundario
T1059Command and Scripting Interpreterexecution80 %
Firmware update sin validación de autenticidad permite inyección en cadena de suministro (T1195). El atacante manipula el canal de actualización para instalar código no autorizado con privilegios elevados (T1059).
Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
