Intel-SA-00086 Security Review Cumulative Update
Intel recently released a security update (Intel-SA-00086), regarding Intel ME 11.x, SPS 4.0, and TXE 3.0 intel products.
The following Firmware are impacted:
Intel Management Engine (ME) Firmware versions 11.0/11.5/11.6/11.7/11.10/11.20
Intel Server Platform Services (SPS) Firmware version 4.0
Intel Trusted Execution Engine (TXE) version 3.0
And the following Intel products are affected:
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
An attacker could gain unauthorized access to the platform, the Intel ME feature, and 3rd party secrets protected by the Intel Management Engine (ME), the Intel Server Platform Service (SPS), or the 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. Concrete impact may be "load and execute arbitrary code outside the visibility of the user and operating system", or "system crash or system instability".
The assigned CVEs are:
Intel Manageability Engine Firmware 11.0.x.x/11.5.x.x/11.6.x.x/11.7.x.x/11.10.x.x/11.20.x.x
Intel Manageability Engine Firmware 8.x/9.x/10.x
Server Platform Service 4.0.x.x
IntelTrusted Execution Engine 3.0.x.x
FortiGate model FGT-500E, FGT-501E, affected, but not exploitable under regular functioning conditions (see Solutions below).
FortiWeb model FWB-1000E has a processor running a firmware affected by the issue, but the vulnerable functions were never enabled.
The following products are NOT impacted:
Note that all related CVEs are "Privilege Escalation" type vulnerabilities. Arbitrary code execution is therefore only possible on the aforementioned products if the attack is combined with a local or remote code execution vulnerability (unrelated to intel issues) in the affected products. The Intel CVEs only aggravate the situation, if such vulnerabilities exist. Based on the above, the impact to Fortinet products is low to "nonexistent".
