🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1203Exploitation for Client Executionexecution85 % - Impacto principal
T1059.001PowerShellexecution75 % - Impacto secundario
T1005Data from Local Systemcollection60 % - Impacto secundario
T1078Valid Accountsstealth · persistence · privilege escalation · initial access65 %
AV:N/UI:R indica explotación remota con interacción del usuario (T1203). Bypass de MSHTML permite ejecución de código en cliente. CWE-20 sugiere validación insuficiente, típico de escalada hacia T1059 (comandos), T1078 (acceso) y T1005 (lectura datos).
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.
