grub2: Crafted grub.cfg file can lead to arbitrary code execution during boot process

Jul 29, 2020
microsoft2020-Jul/CVE-2020-10713Important

A flaw was found in grub2 prior to version 2.06. An attacker may use the GRUB 2 flaw to hijack and tamper the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to load an untrusted or modified kernel an attacker would first need to establish access to the system such as gaining physical access obtain the ability to alter a pxe-boot network or have remote access to a networked system with root access. With this access an attacker could then craft a string to cause a buffer overflow by injecting a malicious payload that leads to arbitrary code execution within GRUB. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
