| Last revised: | 02/14/2023 |
Summary:
Potential security vulnerabilities in the Integrated Baseboard Management Controller (BMC) and OpenBMC firmware in some Intel® platforms may allow escalation of privilege or denial of service. Intel is releasing firmware updates to mitigate these potential vulnerabilities.
Vulnerability Details:
CVEID: CVE-2021-39296 (Non-Intel issued)
Description: Issue affecting netipmid (IPMI lan+) interface. An attacker might craft IPMI messages to gain root access to the BMC bypassing authentication.
CVSS Base Score: 10.0 Critical
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
CVEID: CVE-2022-35729
Description: Out of bounds read in firmware for OpenBMC in some Intel(R) platforms before version 0.72 may allow unauthenticated user to potentially enable denial of service via network access.
CVSS Base Score: 7.5 High
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CVEID: CVE-2022-29494
Description: Improper input validation in firmware for OpenBMC in some Intel(R) platforms before versions egs-0.91-179 and bhs-04-45 may allow an authenticated user to potentially enable denial of service via network access.
CVSS Base Score: 6.5 Medium
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
CVEID: CVE-2021-39295 (Non-Intel issued)
Description: Issue affecting netipmid (IPMI lan+) interface. An attacker might craft IPMI messages to cause denial of service to the BMC.
CVSS Base Score: 6.1 Medium
CVSS Vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:L
CVEID: CVE-2022-29493
Description: Uncaught exception in webserver for the Integrated BMC in some Intel(R) platforms before versions 2.86, 2.09 and 2.78 may allow a privileged user to potentially enable denial of service via network access.
CVSS Base Score: 4.5 Medium
CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:N/A:H
Affected Products:
Integrated BMC firmware before versions 2.86, 2.09 and 2.78 in some Intel® platforms.
