Original Publication Date: 26 Mar, 2021
Security Advisory Description
o CVE-2020-24497
Insufficient Access Control in the firmware for Intel(R) E810 Ethernet
Controllers before version 1.4.1.13 may allow a privileged user to
potentially enable denial of service via local access.
o CVE-2020-24498
Buffer overflow in the firmware for Intel(R) E810 Ethernet Controllers
before version 1.4.1.13 may allow a privileged user to potentially enable
denial of service via local access.
o CVE-2020-24500
Buffer overflow in the firmware for Intel(R) E810 Ethernet Controllers
before version 1.4.1.13 may allow a privileged user to potentially enable a
denial of service via local access.
o CVE-2020-24501
Buffer overflow in the firmware for Intel(R) E810 Ethernet Controllers
before version 1.4.1.13 may allow an unauthenticated user to potentially
enable denial of service via adjacent access.
o CVE-2020-24505
Insufficient input validation in the firmware for the Intel(R) 700-series
of Ethernet Controllers before version 7.3 may allow a privileged user to
potentially enable denial of service via local access.
Impact
This vulnerability may allow a privileged user to potentially enable denial of
service (DoS) by way of local access.
Security Advisory Status
F5 Product Development has assigned ID 1004797 (F5OS) to this vulnerability.
To determine if your product and version have been evaluated for this
vulnerability, refer to the Applies to (see versions) box. To determine if your
release is known to be vulnerable, the components or features that are affected
by the vulnerability, and for information about releases, point releases, or
hotfixes that address the vulnerability, refer to the following table. For more
information about security advisory versioning, refer to K51812227:
Understanding security advisory versioning.
Note: After a fix is introduced for a vulnerable version, that fix applies to
all subsequent point releases for that version and no additional fixes for that
version will be listed in the table. For example, when a fix is introduced in
14.1.2.3, the fix applies to 14.1.2.4 and all later point releases.

^1F5 only evaluates software versions that have not yet reached the End of
Technical Support (EoTS) phase of their lifecycle.
^2The CVSSv3 score link takes you to a resource outside of AskF5, and it is
possible that the document may be removed without our knowledge.
Recommended Actions
If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by installing a version listed in
the Fixes introduced in column. If the Fixes introduced in column does not list
a version for your branch, then no update candidate currently exists for that
branch and F5 recommends upgrading to a version with the fix (refer to the
table).
If the Fixes introduced in column lists a version prior to the one you are
running, in the same branch, then your version should have the fix.

Insufficient access control in the firmware for the Intel(R) 722 Ethernet
Controllers before version 1.5 may allow a privileged user to potentially
enable a denial of service via local access.
o CVE-2020-24493
Insufficient access control in the firmware for the Intel(R) 700-series of
Ethernet Controllers before version 8.0 may allow a privileged user to
potentially enable denial of service via local access.
o CVE-2020-24494
Insufficient access control in the firmware for the Intel(R) 722 Ethernet
Controllers before version 1.4.3 may allow a privileged user to potentially
enable denial of service via local access.
o CVE-2020-24495
Insufficient access control in the firmware for the Intel(R) 700-series of

potentially enable denial of service via local access.
o CVE-2020-24496
Insufficient input validation in the firmware for Intel(R) 722 Ethernet
Controllers before version 1.4.3 may allow a privileged user to potentially
enable denial of service via local access.
Impact
This vulnerability may allow a privileged user to enable a denial-of-service
