CVE-2014-7992

Estado: ModificadaMedia (5)—

La implementación DLSw en Cisco IOS no inicializa los buffers de paquetes, lo que permite a atacantes remotos obtener información sensible de credenciales de la memoria de procesos a través de una sesion en el puerto TCP 2067, también conocido como ID CSCur14014.

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).
