CVE-2023-43636 · GHSA-5h7v-g49c-h887
- Affected
- Go github.com/lf-edge/eve/pkg/grub < 0.0.0-20220708121648-5fef4d92e758
- Fixed in
- 0.0.0-20220708121648-5fef4d92e758· Vendor fix available
- Issue
- Impact Measured boot validates BIOS, grub, kernel cmdline, and initrd but not the entire rootfs. Thus, an attacker can create an EVE-OS rootfs squashfs image with some files modified and take out the disk and replace the existing rootfs image without that being detected by measure boot and remote attestation. Patches Fixed in 8.6.0 and 8.12.1-lts Workarounds None
Recommended action: Upgrade to 0.0.0-20220708121648-5fef4d92e758 (pre-release) or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
