CVE-2019-1758
Estado: ModificadaMedia (4.3)—
Una vulnerabilidad en la función 802.1x del software Cisco IOS en los switches Catalyst 6500 Series podría permitir que un atacante adyacente sin autenticar acceda a la red antes de autenticarse. La vulnerabilidad se debe a cómo los paquetes 802.1x se manejan en la ruta del proceso. Un atacante podría explotar esta vulnerabilidad intentando conectarse a la red en un puerto configurado por 802.1x. Un exploit exitoso podría permitir que el atacante obtenga acceso a la red de forma intermitente.
CVSS
- Versión: 3.0
- Vector: CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
- Puntuación base: 4.3

"value": "A vulnerability in 802.1x function of Cisco IOS Software on the Catalyst 6500 Series Switches could allow an unauthenticated, adjacent attacker to access the network prior to authentication. The vulnerability is due to how the 802.1x packets are handled in the process path. An attacker could exploit this vulnerability by attempting to connect to the network on an 802.1x configured port. A successful exploit could allow the attacker to intermittently obtain access to the network."
