EVE Has Partially Predetermined Vault Key
🔗 CVE IDs covered (1)
📋 Description
Impact
The deriveVaultKey function calls retrieveCloudKey which always returns "foobarfoobarfoobarfoobarfoobarfo". When merged with the randomly generated 32-byte key using mergeKeys (16 bytes from each), the last 16 bytes are always "arfoobarfoobarfo". This enables an attacker with physical access to the EVE-OS device to attempt to brute force the remaining 128 bits of key.
Patches
Fixed in 7.10 and 8.12.1-lts
Workarounds
None
