CVE-2011-1965

Estado: ModificadaAlta (7.1)—💥 Exploit

Tcpip.sys en la pila TCP/IP en Microsoft Windows 7 Gold y SP1 y Windows Server 2008 R2 y R2 SP1 no implementa correctamente la URL basada en QoS, permitiendo a atacantes remotos provocar una denegación de servicio (reinicio) a través de una URL manipulada a un servidor web, también conocido como "Denegación de servicio de la vulnerabilidad TCP/IP QoS"

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.
