Estado: ModificadaAlta (9.3)—💥 Exploit

Una vulnerabilidad de uso de la memoria previamente liberada en la función CRecordInstance::TransferToDestination en la biblioteca mshtml.dll en Internet Explorer de Microsoft versiones 5.01, 6, 6 SP1 y 7, permite a atacantes remotos ejecutar código arbitrario por medio de enlaces DSO involucrando a (1) una Island XML, (2 ) DSOs XML, y (3) Tabular Data Control (TDC) en un documento HTML o XML diseñado, como es demostrado mediante elementos anidados SPAN o MARQUEE, y explotados "in the wild" en diciembre de 2008.

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: 67%
Percentil entre todas las CVEs puntuadas: 99
Fecha de la puntuación: 8/10/2026

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.
