Advisory Summary

There is no cryptographic relation between the password provided by the end user and the key used for encryption of user data. The key used for encryption of user data is protected by an internal parameter of the drive, and if extracted, could allow data to be decrypted without knowledge of proper authentication credentials.

Mitigation: Use software encryption.

CVE Number: CVE-2018-12037
Reported by: Carlo Meijer (Radboud University, the Netherlands) and Bernard van Gastel (Radboud University, the Netherlands, Open University of the Netherlands)

A vulnerability in the wear-leveling algorithm of the drive may cause cryptographically sensitive parameters (such as data encryption keys) to remain on the drive media after their intended erasure.

Mitigation: Use software encryption.

CVE Number: CVE-2019-11686
Reported by: Carlo Meijer (Radboud University, the Netherlands) and Bernard van Gastel (Radboud University, the Netherlands, Open University of the Netherlands)

The firmware update authentication method for affected devices relies on a symmetric HMAC digest. The key used to validate this digest is present in a protected area of the device, and if extracted could be used to install arbitrary firmware to other devices.

CVE Number: CVE-2019-10706
Reported by: Carlo Meijer (Radboud University, the Netherlands) and Bernard van Gastel (Radboud University, the Netherlands, Open University of the Netherlands)

A vulnerability in the secure boot scheme may allow internally protected parameters to be extracted. This vulnerability affects the following drive model numbers, which use secure boot to protect key material stored internally to the drive:

  • SD8TB8U-XXXX-XXXX
  • SD8TN8U-XXXX-XXXX

CVE Number: CVE-2019-10636
Reported by: Carlo Meijer (Radboud University, the Netherlands) and Bernard van Gastel (Radboud University, the Netherlands, Open University of the Netherlands)
