Affected packages
• Go github.com/lf-edge/eve: < 0.0.0-20230126065759-d9383a7ee4e1 → fixed in 0.0.0-20230126065759-d9383a7ee4e1
Description
Impact
PCR14 is not included in the list of PCRs that seal/unseal the vault key. Additionally, the vault key uses SHA1 PCRs instead of SHA256.
Thus an attacker with physical access can take out the disk, use a different computer to modify the files in the /config partition, and re-insert the disk and boot without the change being detected by measured boot and remote attestation.
Patches
Fixed in EVE version 9.4.3-lts
Workarounds
None (apart from preventing physical access to the device)
