CVE-2008-4324

Estado: ModificadaMedia (5)—💥 Exploit

El despachador de eventos de la interfaz de usuario en Mozilla Firefox versión 3.0.3, en Windows XP SP2, permite a los atacantes remotos causar una denegación de servicio (desreferencia del puntero NULL y bloqueo de aplicación) por medio de una serie de eventos de keypress, click, onkeydown, onkeyup, onmousedown, y onmouseup. NOTA: más tarde se reportó que Firefox versión 3.0.2 en Mac OS X versión 10.5 también está afectado.

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.
