CVE-2011-1255

Estado: ModificadaAlta (9.3)—💥 Exploit

La implantación de extensiones multimedia interactivas temporizadas ("Timed Interactive Multimedia Extensions" o HTML+TIME) en Microsoft Internet Explorer 6 hasta la versión 8 no maneja apropiadamente los objetos en memoria, lo que permite a atacantes remotos ejecutar código arbitraio accediendo a un objeto que (1) no ha sido apropiadamente inicializado o (2) ha sido borrado. También conocido como "Vulnerabilidad de corrupción de memoria de elemento Time".

CVSS

Versión: 2.0
Vector: AV:N/AC:M/Au:N/C:C/I:C/A:C
Puntuación base: 9.3

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 42%
Percentil entre todas las CVEs puntuadas: 99
Fecha de la puntuación: 7/10/2026

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).

💥 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.
