CVE-2006-3899

Estado: ModificadaMedia (5)—💥 Exploit

Microsoft Internet Explorer 6.0 en Windows XP SP2 permite a atacantes remotos provocar una denegación de servicio (cierre de aplicación) llamando a la función stringToBinary del objeto ActiveX CEnroll.CEnroll.2 con un segundo argumento largo, lo cual dispara un acceso a memoria inválido dentro de la función SysAllocStringLen.

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).

💥 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.
