CVE-2011-3658

Estado: ModificadaAlta (7.5)—💥 Exploit

The SVG implementation in Mozilla Firefox 8.0, Thunderbird 8.0, and SeaMonkey 2.5 does not properly interact with DOMAttrModified event handlers, which allows remote attackers to cause a denial of service (out-of-bounds memory access) or possibly have unspecified other impact via vectors involving removal of SVG elements.

CVSS

Versión: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
Puntuación base: 7.5

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 70%
Percentil entre todas las CVEs puntuadas: 99
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.
