CVE-2014-3293

Estado: ModificadaMedia (5)—

Cisco IOS 15.4(3)S0b en los dispositivos ASR901 toma decisiones incorrectas para utilizar la CPU para el procesamiento de paquetes IPv4, lo que permite a atacantes remotos causar una denegación de servicio (cambios constantes 'flapping' entre vecinos BGP) mediante el envío de muchos paquetes IPv4 manipulados, también conocido como Bug ID CSCuo29736.

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).
