In July 2018 another set of vulnerabilities was disclosed (SA-00112). Unlike SA-00075, this bug is even present if AMT is absent, not provisioned or if the ME was "disabled" by any of the known unofficial methods. Additional major security flaws in the ME affecting a very large number of computers incorporating ME, Trusted Execution Engine (TXE), and Server Platform Services (SPS) firmware, from Skylake in 2015 to Coffee Lake in 2017, were confirmed by Intel on 20 November 2017 (SA-00086). Several ways to disable the ME without authorization that could allow ME's functions to be sabotaged have been found. Every Intel platform with provisioned Intel Standard Manageability, Active Management Technology, or Small Business Technology, from Nehalem in 2008 to Kaby Lake in 2017 has a remotely exploitable security hole in the ME. On May 1, 2017, Intel confirmed a Remote Elevation of Privilege bug (SA-00075) in its Management Technology. Several weaknesses have been found in the ME. Near Field Communication, a middleware for NFC readers and vendors to access NFC cards and provide secure element access, found in later MEI versions.Intel Platform Trust Technology (PTT), a firmware-based Trusted Platform Module (TPM).Intel Anti-Theft Technology (AT), discontinued in 2015.

Communication with the QST firmware subsystem is documented and available through the official software development kit (SDK). Quiet System Technology (QST), formerly known as Advanced Fan Speed Control (AFSC), which provides support for acoustically-optimized fan speed control, and monitoring of temperature, voltage, current and fan speed sensors that are provided in the chipset, CPU and other devices present on the motherboard.Intel Boot Guard (IBG) and Secure Boot.The Russian company Positive Technologies ( Dmitry Sklyarov) found that the ME firmware version 11 runs MINIX 3. Trusted Execution Engine (TXE) – tablet/embedded/low power.Server Platform Services (SPS) – server chipsets and SoCs.Management Engine (ME) – mainstream chipsets.Prior to AMT version 11, CSME was called Intel Management Engine BIOS Extension (Intel MEBx). ME means the HW, SPS is the firmware name on ME and ME contains NM and SiEn). Firmware īy Intel's current terminology as of 2017, ME is one of several firmware sets for the Converged Security and Manageability Engine (CSME)(Need to be updated, as the latest document(#635338 v1.0 P.#6) described.

With the newer Intel architectures ( Intel 5 Series onwards), ME is integrated into the Platform Controller Hub (PCH). Until the release of Nehalem processors, the ME was usually embedded into the motherboard's northbridge, following the Memory Controller Hub (MCH) layout.
Under Linux, communication between the host and the ME is done via /dev/mei or /dev/mei0. The ME also communicates with the host via PCI interface.

The ME has its own MAC and IP address for the out-of-band management interface, with direct access to the Ethernet controller one portion of the Ethernet traffic is diverted to the ME even before reaching the host's operating system, for what support exists in various Ethernet controllers, exported and made configurable via Management Component Transport Protocol (MCTP). Starting with ME 7.1, the ARC processor could also execute signed Java applets. Versions 1.x to 5.x of the ME used the ARCTangent-A4 (32-bit only instructions) whereas versions 6.x to 8.x used the newer ARCompact (mixed 32- and 16-bit instruction set architecture). Previous versions were based on an ARC core, with the Management Engine running the ThreadX RTOS. The ME firmware is stored in a partition of the SPI BIOS Flash, using the Embedded Flash File System (EFFS). Starting with ME 11, it is based on the Intel Quark x86-based 32-bit CPU and runs the MINIX 3 operating system.

Its exact workings are largely undocumented and its code is obfuscated using confidential Huffman tables stored directly in hardware, so the firmware does not contain the information necessary to decode its contents.

Intel claims the ME is required to provide full performance. As long as the chipset or SoC is connected to current (via battery or power supply), it continues to run even when the system is turned off. The subsystem primarily consists of proprietary firmware running on a separate microprocessor that performs tasks during boot-up, while the computer is running, and while it is asleep. While AMT can be unprovisioned by the owner, there is no official, documented way to disable the ME. However, the ME itself is built into all Intel chipsets since 2008, not only those with AMT. AMT gives device owners remote administration of their computer, such as powering it on or off, and reinstalling the operating system. AMT runs on the ME, but is only available on processors with vPro. The Management Engine is often confused with Intel AMT (Intel Active Management Technology).
