Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-345: Insufficient Verification of Data Authenticity, where the product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data. In Github.com/lf edge/eve/pkg/grub, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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
