CVE-2012-1876
Estado: ModificadaAlta (9.3)—💥 Exploit
Consumer Preview de Microsoft Internet Explorer versión 6 hasta la versión 9 y versión 10 , no maneja apropiadamente los objetos en la memoria, lo que permite a los atacantes remotos ejecutar código arbitrario mediante el intento de acceder a un objeto inexistente, lo que conlleva a un desbordamiento del búfer en la región Heap de la memoria, también se conoce como "Col Element Remote Code Execution Vulnerability" demostrado por VUPEN durante una competición Pwn2Own en CanSecWest 2012.
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: 65%
- 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.
