CVE-2020-4701

Estado: ModificadaAlta (7.8)—

IBM DB2 para Linux, UNIX y Windows (incluye DB2 Connect Server) versiones 10.5, 11.1 y 11.5, es vulnerable a un desbordamiento del búfer, causado por una comprobación inapropiada de límites que podría permitir a un atacante local ejecutar código arbitrario en el sistema con privilegios root

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).
