On 14 August 2018, Intel disclosed new vulnerabilities that impact processors which are supported on certain HPE platforms. These vulnerabilities, when exploited for malicious purposes, have the potential to allow the improper gathering of sensitive data.
These vulnerabilities use a speculative execution side-channel method which Intel is referring to as L1 Terminal Fault (L1TF). At the time of disclosure, Intel was not aware of any reports that L1TF has been used in real-world exploits. Intel had released updated microcodes earlier in 2018, and which HPE subsequently has already made available via System ROM updates. These updated microcodes, when coupled with new operating system and/or hypervisor software updates which are now being made available, provide mitigation for these vulnerabilities.
Intel has communicated that there is a portion of the market, principally a subset of those running traditional virtualisation technology in data centres, where it may be advisable to take additional steps to protect systems. This may include enabling specific hypervisor core scheduling features or choosing to disable hyper-threading in specific scenarios. Consult recommendations of OS and Hypervisor vendors.

On 21 May 2018, an industry-wide vulnerability was disclosed that involves modern microprocessor architectures. Based on new security research, there are software analysis methods that, when used for malicious purposes, have the potential to improperly gather sensitive data from computing devices that are operating as designed. At this time, this vulnerability is known as Speculative Store Bypass or Variant 4 (CVE-2018-3639). While this vulnerability shares many similarities with the recently disclosed Side-Channel Analysis Method, or Spectre and Meltdown, this is a new vulnerability requiring new and unique mitigations.
The Speculative Store Bypass or Variant 4 vulnerability impacts microprocessor architectures from multiple CPU vendors, including Intel, AMD and ARM. To address this vulnerability, hardware and software vendors from across the industry, including HPE, have been working together to develop mitigation strategies. Mitigation for Intel-based products requires both OS updates and System ROM updates including a new Intel microcode. Mitigation for AMD-based products only require an OS update.
In addition, on 21 May 2018, another vulnerability was disclosed referred to as Rogue Register Load or Variant 3A (CVE-2018-3640) that allows an attacker to improperly access processor registers. This vulnerability impacts Intel-based products only. Mitigation for this vulnerability requires only a System ROM update including a new Intel microcode. The same microcode required for mitigation of Speculative Store Bypass or Variant 4 will also mitigate Rogue Register Load or Variant 3A.
Intel Itanium Processors are not exposed to either Speculative Store Bypass (CVE-2018-3639) or Rogue Register Load (CVE-2018-3640) vulnerabilities.

On 13 March 2018, CTS Labs publicly released information regarding research into security vulnerabilities impacting some AMD products. In terms of HPE Servers, the relevant vulnerabilities impact the AMD Secure Processor (PSP) utilised in the AMD EPYC 7000 Series processor used on the HPE ProLiant DL385 Gen10 and HPE Cloudline CL3150 Gen10 servers. No other HPE server products are impacted by these potential vulnerabilities.
HPE is working with AMD to determine the extent of the vulnerability, and what precautions might be needed to mitigate any exposure. Fortunately, the new HPE DL385 Gen10 product ships with all the new HPE security features, including the HPE Silicon Root of Trust. This new HPE technology protects against typical denial of service or permanent denial of service conditions that might be caused by one part of this vulnerability.
As HPE, working with AMD, learns more information, we will update our communications. In addition, please reference the following statement published by AMD on 20 March.

Recently, one of our suppliers, Intel, discovered a potential security vulnerability in their Server Platform Services (SPS) firmware. The security vulnerability affected several of their processor architectures; however, not all of the impacted Intel server processor architectures are used in HPE products. Specifically, the SPS/ME firmware used in Intel’s architecture can be compromised using physical access. As a result, non-authenticated code may be executed in the SPS environment outside of the visibility of the user and operating system administrator.
These vulnerabilities are not unique to HPE servers and will affect any systems using Intel’s identified processor architectures with impacted firmware revisions.

Overview
On 6 August 2015, at the Black Hat security conference in Las Vegas, security researcher Christopher Domas demonstrated installing a rootkit in a PC's firmware. Domas nicknamed the demonstration a “memory sinkhole’. The attack exploited a feature built into x86 chips manufactured since the mid-1990’s until the 2011 release of Intel Xeon Processor E5-2600 Series (i.e., Sandy Bridge-EP).
The vulnerability exists in the Advanced Programmable Interrupt Controller (APIC), which could allow an attack against the System Management Mode (SMM) memory area used by the operating system to interface with the boot environment like BIOS, EFI, or UEFI. An attacker can exploit this vulnerability to utilise the most privileged of execution modes and potentially overwrite secure features in the boot environment. The demonstration exploit uses the UEFI code features to install a rootkit.
Potential Impact
HPE has investigated the potential impact of this issue on our Enterprise products (i.e., Servers, Storage and Networking) and determined that HPE ProLiant Gen8 and Gen9-series servers are not vulnerable, as Intel previously addressed this design flaw in Intel Xeon Processor E5-2600 Series and subsequent models of server processors. Please note that Intel Xeon Processor E5-2600 Series are used in ProLiant Gen8 servers.
In addition, HPE has investigated the potential impact of this issue on HPE ProLiant G5, G6 and G7-series servers and determined they are not vulnerable to the specific attack demonstrated by Christopher Domas at the Black Hat security conference. Intel is providing a microcode update for these servers which will prevent a potential security breach, if an attempt is made to exploit this vulnerability. As an added measure of security, HPE plans to implement this microcode in updated ProLiant System ROMs, which will be made available for download on HPE Support Center, at no cost to customers.
