Intel says that a piece of software inside virtually all of its newest computer chips contains a critical security flaw that enables an attacker to manipulate security features, run arbitrary code or crash a system.
The chip maker launched a comprehensive review of its firmware after a private team of Russian security researchers reported in August it had found a way to access a backdoor designed to allow some government customers to disable the Management Engine (ME) master controller inside Intel CPUs.
Intel, in an alert issued Monday, reported that the review had identified 11 significant security issues affecting millions of computers, servers and even Internet of Things (IoT) devices.
“In response to issues identified by external researchers, Intel has performed an in-depth comprehensive security review of its Intel Management Engine (ME), Intel Trusted Execution Engine (TXE), and Intel Server Platform Services (SPS) with the objective of enhancing firmware resilience,” the alert states. “As a result, Intel has identified several security vulnerabilities that could potentially place impacted platforms at risk.
“Systems using ME Firmware versions 11.0/11.5/11.6/11.7/11.10/11.20, SPS Firmware version 4.0, and TXE version 3.0 are impacted.”
Intel issued the following list of affected products:
· 6th, 7th & 8th Generation Intel Core™ Processor Family
· Intel Xeon Processor E3-1200 v5 & v6 Product Family
· Intel Xeon Processor Scalable Family
· Intel Xeon Processor W Family
· Intel Atom C3000 Processor Family
· Apollo Lake Intel Atom Processor E3900 series
· Apollo Lake Intel Pentium™
· Celeron N and J series Processors
Intel also released a downloadable detection tool to help users of Windows and Linux to assess whether their hardware is at risk.
“An attacker could gain unauthorized access to platform, Intel ME feature, and 3rd party secrets protected by the Intel Management Engine (ME), Intel Server Platform Service (SPS), or Intel Trusted Execution Engine (TXE),” the alert states.
The chip manufacturer advised the public to update their firmware and check for patches from manufacturers of their specific computer hardware.
“Intel highly recommends checking with your system OEM for updated firmware,” the alert states. “Intel highly recommends that all customers install the updated firmware and Intel Capability License Service on impacted platforms.”
