CVE-2014-3262

Estado: ModificadaMedia (4.3)—

La implementación Locator/ID Separation Protocol (LISP) en Cisco IOS 15.3(3)S y anteriores y IOS XE no valida debidamenete parámetros en mensajes de control ITR, lo que permite a atacantes remotos causar una denegación de servicio (interrupción de CEF y descargas de paquetes) a través de mensajes malformados, también conocido como Bug ID CSCun73782.

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).
