CVE-2007-3845

Estado: ModificadaAlta (9.3)—💥 Exploit

Mozilla Firefox anterior a 2.0.0.6, Thunderbird anterior a 1.5.0.13 y 2.x anterior a 2.0.0.6, y SeaMonkey anterior a 1.1.4 permite a atacantes remotos ejecutar código de su elección mediante ciertos vectores asociados con el lanzamiento de "un programa de manejo de ficheros basado en la extensión del fichero al final del URI", una variante de CVE-2007-4041. El vendedor afirma que "todavía es posible lanzar un manipulador de tipo de fichero basado en la extensión en lugar de el manipulador de protocolo registrado".

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: 5.70%
Percentil entre todas las CVEs puntuadas: 93
Fecha de la puntuación: 7/10/2026

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.
