Official description
Diebold Nixdorf Vynamic Security Suite through 4.3.0 SR06 contains functionality that allows the removal of critical system files before the filesystem is properly mounted (e.g., leveraging a delete call in /etc/rc.d/init.d/mountfs to remove the /etc/fstab file). This can allow code execution and, in some versions, enable recovery of TPM Disk Encryption keys and decryption of the Windows system partition.

The underlying weakness: Improper Privilege Management
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
