SanDisk Cruzer Enterprise USB flash drives validate passwords with a program running on the host computer rather than the device hardware, which allows physically proximate attackers to access the cleartext drive contents via a modified program.

SanDisk Cruzer Enterprise USB flash drives use a fixed 256-bit key for obtaining access to the cleartext drive contents, which makes it easier for physically proximate attackers to read or modify data by determining and providing this key.

SanDisk Cruzer Enterprise USB flash drives do not prevent password replay attacks, which allows physically proximate attackers to access the cleartext drive contents by providing a key that was captured in a USB data stream at an earlier time.

SanDisk Secure Access 3.01 vault decrypts and copies encrypted files to a temporary folder, where they can remain indefinitely in certain situations, such as if the file is being edited when the user exits the application or if the application crashes.
