The vulnerability is due to improper validation of the server firmware upgrade images. An attacker could exploit this vulnerability by installing a server firmware version that would allow the attacker to disable UEFI Secure Boot. A successful exploit could allow the attacker to bypass the signature validation checks that are done by UEFI 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."},{"lang":"es","value":"Una vulnerabilidad en el firmware de Cisco UCS C-Series Rack Servers, podría permitir a un atacante físico autenticado omitir las comprobaciones de validación de Unified Extensible Firmware Interface (UEFI) Secure Boot y cargar una imagen de software comprometida en un dispositivo afectado. La vulnerabilidad es debido a una comprobación inapropiada de las imágenes de actualización del firmware del servidor. Un atacante podría explotar esta vulnerabilidad mediante la instalación una versión de firmware del servidor que le permitiría deshabilitar el UEFI Secure Boot. Una explotación con éxito podría permitir al atacante omitir las comprobaciones de validación de firmas que realiza la tecnología UEFI Secure Boot y cargar una imagen de software comprometida en el dispositivo afectado. Una imagen de software comprometida es cualquier imagen de software que no haya sido firmada digitalmente por
