CVE-2007-1562

Estado: ModificadaMedia (6.8)—💥 Exploit
La implementación del protocolo FTP en Mozilla Firefox anterior a versión 1.5.0.11 y versión 2.x anterior a 2.0.0.3 permite a los atacantes remotos forzar al cliente a conectarse a otros servidores, realizar un análisis de puerto proxy o conseguir información confidencial por medio de la especificación de una dirección de servidor alterno en una respuesta PASV de FTP.
CVSS

Versión: 2.0
Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
Puntuación base: 6.8
Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 14%
Percentil entre todas las CVEs puntuadas: 96
Fecha de la puntuación: 14/10/2026
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.
