🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1203Exploitation for Client Executionexecution95 % - Impacto principal
T1059Command and Scripting Interpreterexecution70 % - Impacto secundario
T1565.001Stored Data Manipulationimpact60 %
UI:R (requiere interacción del usuario al procesar contenido web malicioso en navegador) → T1203. Corrupción de memoria en Safari/iOS puede permitir ejecución de código arbitrario (T1059) o manipulación de datos en memoria (T1565.001).
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.
