CVE-2009-3103

Estado: ModificadaAlta (10)—💥 Exploit

Error de índice de matriz en la implementación del protocolo SMBv2 en srv2.sys en Windows Vista versión Gold, SP1 y SP2, Windows Server 2008 versión Gold y SP2, y Windows 7 RC, de Microsoft, permite a los atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (bloqueo de sistema) por medio de un carácter & (ampersand) en un campo de encabezado Process ID High en un paquete NEGOTIATE PROTOCOL REQUEST, que activa un intento de desreferencia de una ubicación de memoria fuera de límites, también se conoce como "SMBv2 Negotiation Vulnerability" NOTA: algunos de estos datos fueron obtenidos de la información de terceros.

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.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
