CVE-2025-46373

Estado: ModificadaAlta (7.8)—

A Heap-based Buffer Overflow vulnerability [CWE-122] vulnerability in Fortinet FortiClientWindows 7.4.0 through 7.4.3, FortiClientWindows 7.2.0 through 7.2.8 may allow an authenticated local IPSec user to execute arbitrary code or commands via "fortips_74.sys". The attacker would need to bypass the Windows heap integrity protections

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.

Desbordamiento de buffer en controlador de kernel (fortips_74.sys) accesible por usuario local autenticado sin interacción, requiere bypass de protecciones del heap. AV:L, PR:L, UI:N indican escalada de privilegios local (T1068) con impacto en 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.
