Description
The vCenter Native Key Provider feature was introduced in U2 and acts as a key provider for encryption-based capabilities, such as encrypted virtual machines without requiring an external KMS solution. When enabling this feature, a backup must be taken that is a PKCS#12 formatted file. If no password is provided during the backup process, this presents the opportunity for this to be used maliciously and compromise the environment.
