Intel ID: INTEL-SA-00613
Advisory Category: Firmware
Impact of vulnerability : Escalation of Privilege
Severity rating : HIGH
Original release: 05/10/2022
Last revised: 05/10/2022
Summary:
A potential security vulnerability in Intel Boot Guard and Intel Trusted
Execution Technology (TXT) for some Intel processors may allow escalation of
privilege. Intel is releasing firmware updates and prescriptive guidance to
mitigate this potential vulnerability.
Vulnerability Details:
CVEID: CVE-2022-0004
Description: Hardware debug modes and processor INIT setting that allow
override of locks for some Intel(R) Processors in Intel(R) Boot Guard and Intel
(R) TXT may allow an unauthenticated user to potentially enable escalation of
privilege via physical access.
CVSS Base Score: 7.3 High
CVSS Vector: CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N (Physical,
unauthenticated)
CVSS Base Score: 7.3 High
CVSS Vector: CVSS:3.1/AV:A/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:N (Adjacent network,
authenticated)

Recommendations:
Intel recommends updating Intel CSME to the latest version (see provided
table).
Intel also recommends following the previously published guidance on disabling
the CPU Debug feature when Intel Boot Guard is enabled. Please consult this
Intel Debug paper for more details.
Intel also recommends disabling the BSP (Bootstrap Processor) INIT (DBI) bit to
enable protections against an INIT bypassing the startup Authenticated Code
Module (ACM). This setting change is available in the latest version of Intel
CSME.
Intel recommends that users of Intel CSME update to the latest version provided
by the system manufacturer that addresses these issues.

Prescriptive guidance : Intel is not releasing updated Intel SPS firmware to
disable the CPU debug feature on server products.
Intel recommends users follow existing security best practices and alternate
security controls, including:
. Ensure physical security of server systems, and secure BMC access if BMC has
adjacent-network JTAG access.
Acknowledgements:
The following issue was found internally by Intel employees. Intel would like
to thank Ki W Yoon.
Subsequently, this issue was reported by Mickey Shkatov. Intel would like to
thank Mickey Shkatov from Eclypsium for reporting this issue.
Intel, and nearly the entire technology industry, follows a disclosure practice
called Coordinated Disclosure, under which a cybersecurity vulnerability is
generally publicly disclosed only after mitigations are available.
