This Unpatchable Flaw Affects All Intel CPUs Released in Last 5 Years

March 06, 2020Wang Wei
All Intel processors released in the past 5 years contain an unpatchable vulnerability that could allow hackers to compromise almost every hardware-enabled security technology that are otherwise designed to shield sensitive data of users even when a system gets compromised. The vulnerability, tracked as CVE-2019-0090 , resides in the hard-coded firmware running on the ROM ("read-only memory") of the Intel's Converged Security and Management Engine (CSME), which can't be patched without replacing the silicon. Intel CSME is a separate security micro-controller incorporated into the processors that provides an isolated execution environment protected from the host opening system running on the main CPU. It is responsible for the initial authentication of Intel-based systems by loading and verifying firmware components, root of trust based secure boot, and also cryptographically authenticates the BIOS, Microsoft System Guard, BitLocker, and other security features

Researchers Discover TPM-Fail Vulnerabilities Affecting Billions of Devices

A team of cybersecurity researchers today disclosed details of two new potentially serious CPU vulnerabilities that could allow attackers to retrieve cryptographic keys protected inside TPM chips manufactured by STMicroelectronics or firmware-based Intel TPMs. Trusted Platform Module (TPM) is a specialized hardware or firmware-based security solution that has been designed to store and protect sensitive information from attackers even when your operating system gets compromised. TMP technology is being used widely by billion of desktops, laptops, servers, smartphones, and even by Internet-of-Things (IoT) devices to protect encryption keys, passwords, and digital certificates. Collectively dubbed as TPM-Fail , both newly found vulnerabilities, as listed below, leverage a timing-based side-channel attack to recover cryptographic keys that are otherwise supposed to remain safely inside the chips.
