In recent years, we have been witnessing a steady increase in security vulnerabilities in firmware. Nearly all of these issues require local (often privileged) or physical access to exploit. In this talk, we will present novel *remote* attacks on system firmware.
In this talk, we will show different remote attack vectors into system firmware, including networking, updates over the Internet, and error reporting. We will also be demonstrating and remotely exploiting vulnerabilities in different UEFI firmware implementations which can lead to installing persistent implants remotely at scale. The proof-of-concept exploit is less than 800 bytes.
How can we defend against such firmware attacks? We will analyze the remotely exploitable UEFI and BMC attack surface of modern systems, explain specific mitigations for the discussed vulnerabilities, and provide recommendations to detect such attacks and discover compromised systems.
