Resumen Ejecutivo
Hoy, 19 de abril de 2022, Lenovo ha publicado un aviso de seguridad sobre 3 vulnerabilidades que afectan a su Unified Extensible Firmware Interface (UEFI) y se ha estimado que al menos 100 modelos de sus laptops se encuentran vulnerables.
Dos de las vulnerabilidades (CVE-2021-3971, CVE-2021-3972) permiten a un atacante desactivar la protección del chip de memoria flash SPI donde se almacena el firmware UEFI y desactivar la función UEFI Secure Boot. Mientras que la tercera (CVE-2021-3970) podría permitir a un atacante local ejecutar código arbitrario con privilegios en el sistema.
Información más especifica:
- CVE-2021-3970: Una posible vulnerabilidad en LenovoVariable SMI Handler, debido a una validación insuficiente en algunos modelos de Lenovo puede permitir la ejecución de código arbitrario de manera local.
- CVE-2021-3971: Una posible vulnerabilidad de un controlador utilizado durante procesos de fabricación antiguos en algunos dispositivos de consumo las laptops que se incluyó por error en la imagen de la BIOS, la cual, podría permitir a un atacante con privilegios modificar la región de protección del firmware mediante la modificación de una variable de la NVRAM.
- CVE-2021-3972: Una posible vulnerabilidad de un controlador utilizado durante el proceso de fabricación en algunos dispositivos de Lenovo, consumo que no se desactivó por error, lo que podría permitir a un atacante con privilegios modificar la configuración de arranque seguro mediante la modificación de una variable de la NVRAM.
