CVE-2013-1347

Estado: AnalizadaAlta (8.8)⚠ Explotación activa💥 Exploit

Microsoft Internet Explorer 8 no maneja adecuadamente los objetos en memoria, lo que permite a atacantes remotos ejecutar código de su elección cuando acceden al objeto que (1)no se ha asignado adecuadamente o (2) se ha eliminado, como han sido explotadas a lo largo de mayo.

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).

CISA KEV — explotada activamente

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

CWE-416 (use-after-free) en IE8 con vector AV:N/UI:R permite ejecución arbitraria de código remoto tras interacción del usuario (acceso a objeto malicioso en memoria).

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.
