CVE-2019-12655

Estado: ModificadaAlta (7.5)—

Una vulnerabilidad en la funcionalidad application layer gateway (ALG) de FTP, utilizada por Network Address Translation (NAT), NAT IPv6 a IPv4 (NAT64) y el Zone-Based Policy Firewall (ZBFW) en Software Cisco IOS XE, podría permitir a un atacante remoto no autenticado causar que un dispositivo afectado se recargue. La vulnerabilidad es debido a un desbordamiento de búfer que ocurre cuando un dispositivo afectado inspecciona determinado tráfico FTP. Un atacante podría explotar esta vulnerabilidad realizando una transferencia FTP específica por medio del dispositivo. Una explotación con éxito podría permitir al atacante causar que el dispositivo se recargue.

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).
