🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1068Exploitation for Privilege Escalationprivilege escalation95 % - Impacto secundario
T1548Abuse Elevation Control Mechanismprivilege escalation80 %
Vulnerabilidad local (AV:L/PR:L) en kernel de Windows que falla al manejar objetos en memoria. Permite escalada de privilegios (T1068). El atacante con acceso local obtiene ejecución con privilegios elevados y control total del sistema (C:H/I:H/A:H).
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.
