🎯 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 principal
T1078.003Local Accountsstealth · persistence · privilege escalation · initial access90 % - Impacto secundario
T1059.001PowerShellexecution85 %
AV:L/PR:L permite escalada local sin privilegios altos. Task Scheduler con CWE-287 (autenticación débil) facilita obtener tokens NT AUTHORITY\SYSTEM (T1078.003) y ejecutar comandos privilegiados (T1059.001).
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.
