Medium

Base vector

AV:P/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:N

Impact

Config partition measurement was moved from PCR 13 to PCR 14 in a commit, but PCR 14 was not added to the list of PCRs that seal/unseal the vault key. As a result, an attacker can remove the disk, use another server to modify the files in the config partition, and then re-insert the disk.

Patches

Fixed in EVE version 9.4.3-lts

Workarounds

None (apart from preventing physical access to the device)
