CVE-2006-5633

Estado: ModificadaMedia (5)—💥 Exploit

Firefox 1.5.0.7 y 2.0, y Seamonkey 1.1b, permite a atacantes remotos provocar una denegación de servicio (caída) creando un objeto rango usando createRange, llamando a selectNode en un nodo DocType (DOCUMENT_TYPE_NODE), y después llamando a createContextualFragment en el rango, lo cual dispara una referencia nula. NOTA: el post original en Bugtraq mencionaba que la ejecución de código era posible, pero análisis posteriores han mostrado que es sólo una referencia nula.

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.
