      "value": "A vulnerability in Cisco IOS ROM Monitor (ROMMON) Software for Cisco Catalyst 6800 Series Switches could allow an unauthenticated, local attacker to bypass Cisco Secure Boot validation checks and load a compromised software image on an affected device. The vulnerability is due to the presence of a hidden command in the affected software. An attacker could exploit this vulnerability by connecting to an affected device via the console, forcing the device into ROMMON mode, and writing a malicious pattern to a specific memory address on the device. A successful exploit could allow the attacker to bypass signature validation checks by Cisco Secure Boot technology and load a compromised software image on the affected device. A compromised software image is any software image that has not been digitally signed by Cisco."

      "value": "Una vulnerabilidad en Cisco IOS ROM Monitor (ROMMON) Software para switches Cisco Catalyst 6800 Series podría permitir que un atacante no autenticado local omita las comprobaciones de validación de Cisco Secure Boot y cargue una imagen de software comprometida en un dispositivo afectado. Esta vulnerabilidad se debe a la presencia de un comando oculto en el software afectado. Un atacante podría explotar esta vulnerabilidad conectándose a un dispositivo afectado mediante la consola, forzando al dispositivo a entrar en modo ROMMON y escribiendo un patrón malicioso a una dirección de memoria específica en el dispositivo. Su explotación con éxito podría permitir que el atacante omita las comprobaciones de validación de firmas de la tecnología Cisco Secure Boot y cargue una imagen de software comprometida en el dispositivo afectado. Una imagen de software comprometida es cualquier imagen de software que no ha sido firmada digitalmente por Cisco."
