CVE-2021-36750Network attack vector

Password disclosure via weak key derivation

Published Dec 22, 2021 · Updated Aug 4, 2024

ENC DataVault before 7.2 and VaultAPI v67 contain an information disclosure flaw that allows remote authenticated users to determine DataVault passwords. The key-derivation implementation mishandles derivation inputs, reducing password protection and enabling recovery of passwords across affected USB-drive software variants. Access requires network reachability and valid credentials; the demonstrated consequence is disclosure of vault passwords rather than service interruption.
