Summary:
In response to issues identified by external researchers, Intel has performed an in-depth comprehensive security review of our Intel® Management Engine (ME), Intel® Server Platform Services (SPS), and Intel® Trusted Execution Engine (TXE) with the objective of enhancing firmware resilience.
As a result, Intel has identified security vulnerabilities that could potentially place impacted platforms at risk.
Description:
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.
As a result, Intel has identified several security vulnerabilities that could potentially place impacted platforms at risk. Systems using ME Firmware versions 6.x/7.x/8.x/9.x/10.x//11.0/11.5/11.6/11.7/11.10/11.20, SPS Firmware version 4.0, and TXE version 3.0 are impacted.
Affected products:
- 1st, 2nd, 3rd, 4th, 5th, 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® Pentium® Processor G Series
- Intel® Atom® C3000 Processor Family
- Apollo Lake Intel® Atom Processor E3900 series
- Apollo Lake Intel® Pentium™
- Celeron™ G, N and J series Processors
Based on the items identified through the comprehensive security review, 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).
This includes scenarios where a successful attacker could:
- Impersonate the ME/SPS/TXE, thereby impacting local security feature attestation validity.
- Load and execute arbitrary code outside the visibility of the user and operating system.
- Cause a system crash or system instability.
- For more information, please see this Intel Support article
If the INTEL-SA-00086 Detection Tool reported your system being vulnerable, please check with your system manufacturer for updated firmware. Links to system manufacturer pages concerning this issue can be found at http://www.intel.com/sa-00086-support.
Note: CVEs referenced in this advisory require Local or Physical access to the system potentially being exploited (AV:L in the CVSSv3 Vectors column) with the exception of CVE-2017-5712. CVE-2017-5712 is potentially exploitable over a network (AV:N).
For an explanation of the conditions where Local access vs. Physical access is required to exploit a vulnerability see the FAQ section listed in the Intel Customer Support article http://www.intel.com/sa-00086-support
More information on the definition of CVSSv3 vectors in general (e.g. AV:L, AV:N) and the other vectors listed in this advisory consult https://first.org/cvss/

Intel has released a downloadable detection tool located at http://www.intel.com/sa-00086-support , which will analyze your system for the vulnerabilities identified in this security advisory.
The only method of restoring the system to its fully functional state is to update both the Intel® ME Firmware and the iCLS software to confirm proper re-provisioning of the platform.
Linux Recovery Tools: This utility is intended for re-provisioning of the platform keys AFTER applying the Intel® ME/TXE firmware update referenced above.
https://github.com/intel/INTEL-SA-00086-Linux-Recovery-Tools
Intel highly recommends that all customers install the updated firmware and Intel® Capability License Service on impacted platforms.
