The vulnerability occurs because the BGP MD5 authentication is bypassed if the peer does not have MD5 authentication configured, the NX-OS device does have BGP MD5 authentication configured, and the NX-OS BGP virtual routing and forwarding (VRF) name is configured to be greater than 19 characters. An attacker could exploit this vulnerability by attempting to establish a BGP session with the NX-OS peer. A successful exploit could allow the attacker to establish a BGP session with the NX-OS device without MD5 authentication. The Cisco implementation of the BGP protocol accepts incoming BGP traffic only from explicitly configured peers. To exploit this vulnerability, an attacker must send the malicious packets over a TCP connection that appears to come from a trusted BGP peer. To do so, the attacker must obtain information about the BGP peers in the affected system’s trusted network."},{"lang":"es","value":"Una vulnerabilidad en la implementación de la autenticación de Message Digest 5 (MD5) de Border Gateway Protocol (BG5) en Cisco NX-OS Software, podría permitir a un atacante remoto no autenticado omitir la autenticación MD5 y establecer una conexión BGP con el dispositivo. La vulnerabilidad ocurre porque la autenticación BGP MD5 es omitida si el peer no tiene la autenticación MD5 configurada, el dispositivo NX-OS presenta la autenticación BGP MD5 configurada y el nombre de NX-OS BGP virtual routing and forwarding (VRF) está configurado para ser mayor de 19 caracteres Un atacante podría explotar esta vulnerabilidad al intentar establecer una sesión BGP con el peer NX-OS. Una explotación con éxito podría permitir al atacante establecer una sesión BGP con el dispositivo NX-OS sin autenticación MD5. La implementación de Cisco del protocolo BGP acepta el tráfico BGP entrante solo de peers configurados explícitamente. Para explotar esta vulnerabilidad, un atacante debe enviar los paquetes maliciosos por medio de una conexión TCP que parece provenir desde un peer BGP de confianza.
