CVE-2022-3675
2.6 · LOWOverview
CVE-2022-3675 is a low-severity vulnerability affecting redhat fedora_coreos. It was published on November 3, 2022 and has a CVSS 3.1 base score of 2.6 (LOW).
This vulnerability has a CVSS 3.1 base score of 2.6, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
Fedora CoreOS supports setting a GRUB bootloader password
using a Butane config. When this feature is enabled, GRUB requires a password to access the
GRUB command-line, modify kernel command-line arguments, or boot
non-default OSTree deployments. Recent Fedora CoreOS releases have a
misconfiguration which allows booting non-default OSTree deployments
without entering a password. This allows someone with access to the
GRUB menu to boot into an older version of Fedora CoreOS, reverting
any security fixes that have recently been applied to the machine. A
password is still required to modify kernel command-line arguments and
to access the GRUB command line.
Remediation
Check the references section for vendor advisories and patches from redhat. Update fedora_coreos to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
