CVE-2017-9312

Estado: ModificadaAlta (7.5)—

El procesamiento del campo option implementado de forma incorrecta en la pila TCP/IP en los dispositivos de seguridad Allen-Bradley L30ERMS en versiones v30 y anteriores provoca una denegación de servicio (DoS). Cuando se recibe un paquete TCP, el dispositivo se reinicia de forma inmediata.

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).
