CVE-2014-3434

Estado: ModificadaMedia (6.9)—💥 Exploit

Buffer overflow in the sysplant driver in Symantec Endpoint Protection (SEP) Client 11.x and 12.x before 12.1 RU4 MP1b, and Small Business Edition before SEP 12.1, allows local users to execute arbitrary code via a long argument to a 0x00222084 IOCTL call.

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.
