CVE-2011-2013

Estado: ModificadaCrítica (9.8)—💥 Exploit

Desbordamiento de entero en la implementación de TCP/IP de Microsoft Windows Vista SP2, Windows Server 2008 SP2, R2, y R2 SP1, y Windows 7 Gold y SP1 permite a atacantes remotos ejecutar código arbitrario enviando una secuencia de paquetes UDP modificados a un puerto cerrado. También conocida como "vulnerabilidad de desbordamiento de contador de referencia".

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.
