CVE-2008-3477

Estado: ModificadaAlta (9.3)—

Microsoft Excel 2000 SP3, 2002 SP3 y 2003 SP2 y SP3 no valida correctamente los datos en la caché VBA Performance, lo que permite a atacantes remotos ejecutar código de su elección mediante un archivo Excel manipulado, también conocida como "Calendar Object Validation Vulnerability (Vulnerabilidad de Validación de Objeto Calendario)".

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).
