CVE-2024-8937

Estado: AplazadaAlta (8.3)—

CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability exists that could cause a potential arbitrary code execution after a successful Man-In-The Middle attack followed by sending a crafted Modbus function call to tamper with memory area involved in the authentication process.

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.

AV:N/AC:H/AT:P indica ataque en red con condiciones adversas (MITM requerido). CWE-119 (buffer overflow) en autenticación Modbus permite RCE tras MITM. T1557 es el vector de entrada; T1059 el impacto (code execution); T1068 secundario por escalada potencial en proceso de autenticación comprometido.

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.
