Running arbitrary code in SMM additionally bypasses SMM-based SPI flash protections against modifications, which can help an attacker to install a firmware backdoor/implant into BIOS. Such a malicious firmware code in BIOS could persist across operating system re-installs. Additionally, this vulnerability potentially could be used by malicious actors to bypass security mechanisms provided by UEFI firmware (for example, Secure Boot and some types of memory isolation for hypervisors). This issue affects: Module name: OverClockSmiHandler SHA256: a204699576e1a48ce915d9d9423380c8e4c197003baf9d17e6504f0265f3039c Module GUID: 4698C2BD-A903-410E-AD1F-5EEF3A1AE422"},{"lang":"es","value":"Un atacante puede explotar esta vulnerabilidad para elevar los privilegios del anillo 0 al anillo -2, ejecutar código arbitrario en el Modo de Administración del Sistema - un entorno más privilegiado que el sistema operativo (SO) y completamente aislado de él. La ejecución de código arbitrario en el SMM también evita las protecciones de la flash SPI basadas en el SMM contra las modificaciones, lo que puede ayudar a un atacante a instalar una puerta trasera/implante de firmware en la BIOS. Este código de firmware malicioso en la BIOS podría persistir a través de las reinstalaciones del sistema operativo. Además, esta vulnerabilidad podría ser usada por actores maliciosos para omitir los mecanismos de seguridad proporcionados por el firmware UEFI (por ejemplo, Secure Boot y algunos tipos de aislamiento de memoria para hipervisores).
