Impact
On boot, the Pillar container checks for /config/authorized_keys. If present with a valid public key, it enables SSH on port 22 with root login. The /config partition is not protected by measured boot, is mutable and unencrypted.
This enables an attacker with physical access to the device to take out the disk, modify the /config partition using a separate server, then insert it, without the inserted key being flagged as an integrity voilation my measured boot and remote attestation.
Patches
Patched in 9.4.3-lts
