Diebold Nixdorf Vynamic Security Suite through 4.3.0 SR01 does not validate file attributes or the contents of /root during integrity validation. This allows code execution, recovery of TPM Disk Encryption keys, decryption of the Windows system partition, and full control of the Windows OS, e.g., through ~/.profile changes.
The product uses a transmission protocol that does not include a mechanism for verifying the integrity of the data during transmission, such as a checksum.
