The bug stems from the failure of the input-output memory management unit … to implement early enough in the firmware boot process. Intel reaffirmed that the bug can only be exploited via physical access.ĬSME … implements the firmware-based used for silicon-based encryption, authentication of UEFI BIOS firmware, Microsoft System Guard and BitLocker, and other security features. the bug can be exploited to recover the Chipset Key, which is the root cryptographic key that can grant an attacker access to everything on a device bug can also be exploited via “local access” – by malware on a device, and not necessarily by having physical access. In May 2019 … the CVE-2019-0090 vulnerability was only described as a firmware bug that allowed an attacker with physical access … to escalate privileges and execute code. a “root of trust” for every other technology running on Intel chipsets. The CSME is also “the cryptographic basis” for other Intel technologies like Intel EPID (Enhanced Privacy ID), Intel Identity Protection, any DRM (Digital Rights Management) technologies, or firmware-based TPMs (Trusted Platform Modules). is responsible for cryptographically verifying and authenticating all firmware loaded on Intel-based computers. … Only the latest Intel 10th generation chips are not vulnerable, researchers said.ĬVE-2019-0090 … impacts the Intel Converged Security and Management Engine (CSME), formerly called the Intel Management Engine BIOS Extension (Intel MEBx).

What’s the craic, Catalin? Mister Cimpanu reports-“ Intel CSME bug is worse than previously thought”:Īttacks are impossible to detect, and a firmware patch only partially fixes the problem. Your humble blogwatcher curated these bloggy bits for your entertainment. In today’s SB Blogwatch, we try not to panic. “Buy new hardware,” seems to be the advice.
