\nProduct: Executive Fingerprint Secure SSD
\nManufacturer: Verbatim
\nAffected Version(s): GDMSFE01-INI3637-C VER1.1
\nTested Version(s): GDMSFE01-INI3637-C VER1.1
\nVulnerability Type: Insufficient Verification of Data
\nAuthenticity (CWE-345)
\nRisk Level: Low
\nSolution Status: Open
\nManufacturer Notification: 2022-02-03
\nSolution Date: –
\nPublic Disclosure: 2022-06-08
\nCVE Reference: CVE-2022-28385
\nAuthor of Advisory: Matthias Deeg (SySS GmbH)<\/p>\n
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<\/p>\n
Overview:<\/p>\n
The Verbatim Executive Fingerprint Secure SSD is a USB drive with AES
\n256-bit hardware encryption and a built-in fingerprint sensor for
\nunlocking the device with previously registered fingerprints.<\/p>\n
The manufacturer describes the product as follows:<\/p>\n
“The AES 256-bit Hardware Encryption seamlessly encrypts all data on the
\ndrive in real-time. The drive is compliant with GDPR requirements as
\n100% of the drive is securely encrypted. The built-in fingerprint
\nrecognition system allows access for up to eight authorised users and
\none administrator who can access the device via a password. The SSD
\ndoes not store passwords in the computer or system’s volatile memory
\nmaking it far more secure than software encryption.”[1]\n
Due to missing integrity checks, an attacker can manipulate the content
\nof the emulated CD-ROM drive containing the Windows and macOS client
\nsoftware.<\/p>\n
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<\/p>\n
Vulnerability Details:<\/p>\n
When analyzing the Verbatim Executive Fingerprint Secure SSD, Matthias
\nDeeg found out that the content of the emulated CD-ROM drive containing
\nthe Windows and macOS client software can be manipulated.<\/p>\n
The content of this emulated CD-ROM drive is stored as ISO-9660 image
\nin the “hidden” sectors of the USB drive that can only be accessed
\nusing special IOCTL commands, or when installing the drive in an
\nexternal disk enclosure.<\/p>\n
The following output exemplarily shows the content of the ISO-9660
\nfile system:<\/p>\n
# mount hidden_sectors.bin \/mnt\/<\/p>\n
# lsd -laR \/mnt\/

By manipulating this ISO-9660 image or replacing it with another one, an
\nattacker is able to store malicious software on the emulated CD-ROM
\ndrive which then may get executed by an unsuspecting victim when using
\nthe device.<\/p>\n
For example, an attacker with temporary physical access during the
\nsupply could program a modified ISO-9660 image on the Verbatim Executive
\nFingerprint Secure SSD, which always uses an attacker-controlled
\npassword for unlocking the device.<\/p>\n
If, later on, the attacker gains access to the used USB drive, he can
\nsimply decrypt all contained user data.<\/p>\n
Storing arbitrary other malicious software is also possible.<\/p>\n
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~<\/p>\n
Proof of Concept (PoC):<\/p>\n
SySS could successfully modify the content of the ISO-9660 image
\ncontaining the Windows and macOS software for unlocking and managing the
\nVerbatim Executive Fingerprint Secure SSD.<\/p>\n
