CVE-2024-36671

Estado: AplazadaCrítica (9.8)—

nodemcu before v3.0.0-release_20240225 was discovered to contain an integer overflow via the getnum function at /modules/struct.c.

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.

Vector CVSS:3.1 AV:N/AC:L/PR:N/UI:N indica explotación remota sin privilegios ni interacción (T1190). CWE-190 (integer overflow) en función getnum permite corrupción de memoria y ejecución de código arbitrario (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.
