CVE-2011-1975

Estado: ModificadaAlta (9.3)—

Vulnerabilidad de ruta de búsqueda no confiable en el componente Data Access Tracing de Windows Data Access Components (Windows DAC) v6.0 de Microsoft Windows 7 Gold y SP1 y Windows Server 2008 R2 y R2 SP1 permite a usuarios locales aumentar privilegios mediante un troyano DLL en el directorio de trabajo actaul, como se ha demostrado en un directorio que contiene un fichero Excel .xlsx. También se conoce como "Vulnerabilidad de carga insegura de biblioteca de Data Access Components"

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).
