CVE-2007-2216

Estado: ModificadaAlta (9.3)—💥 Exploit

El control ActiveX de la biblioteca tblinf32.dll (también conocida como vstlbinf.dll) para Internet Explorer versiones 5.01, 6 SP1 y 7 utiliza una implementación IObjectsafety inapropiada, que permite a los atacantes remotos ejecutar código arbitrario mediante peticiones a la propiedad HelpString, que involucra un argumento de archivo DLL elaborado para la función TypeLibInfoFromFile, que sobrescribe la propiedad HelpStringDll para llamar a la función DLLGetDocumentation en otro archivo DLL, también se conoce como "ActiveX Object Vulnerability."

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.
