Potential security vulnerability in Intel Active Management Technology (AMT),
and Intel Standard Manageability (ISM) may allow escalation of privilege. Intel
is releasing firmware updates to mitigate this potential vulnerability.

Vulnerability Details:

CVEID: CVE-2020-8758

Description: Improper buffer restrictions in network subsystem in provisioned
Intel(R) AMT and Intel(R) ISM versions before 11.8.79, 11.12.79, 11.22.79,
12.0.68 and 14.0.39 may allow an unauthenticated user to potentially enable
escalation of privilege via network access. On un-provisioned systems, an
authenticated user may potentially enable escalation of privilege via local

CVSS Vector (Provisioned, unauthenticated, network):

CVSS Base Score: 9.8 Critical


CVSS Vector (Un-provisioned, authenticated, local):

CVSS Base Score: 7.8


Affected Products:

Intel AMT and Intel ISM versions before 11.8.79, 11.12.79, 11.22.79, 12.0.68
and 14.0.39.

Note: Firmware versions of Intel AMT 3.x thru 10.x are no longer supported,
thus were not assessed for the vulnerabilities/CVEs listed in this Advisory.
There is no new release planned for these versions.


Intel recommends that users of Intel AMT and Intel ISM update to the latest
version provided by the system manufacturer that addresses these issues.


This issue was found internally by Intel employees. Intel would like to thank
Yaakov Cohen, Yocheved Butterman and Yossef Kuszer.

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.
