When analyzing the Verbatim Executive Fingerprint Secure SSD, Matthias Deeg found out that the content of the emulated CD-ROM drive containing the Windows and macOS client software can be manipulated. The content of this emulated CD-ROM drive is stored as ISO-9660 image in the "hidden" sectors of the USB drive that can only be accessed using special IOCTL commands, or when installing the drive in an external disk enclosure.

When analyzing the Verbatim Executive Fingerprint Secure SSD, Matthias Deeg found out that the validation of the firmware for the USB-to-SATA bridge controller INIC-3637EN only consists of a simple CRC-16 check (XMODEM CRC-16). Thus, an attacker is able to store malicious firmware code for the INIC-3637EN with a correct checksum on the used SPI flash memory chip (XT25F01D), which then gets successfully executed by the USB-to-SATA bridge controller.

When analyzing the Verbatim Fingerprint Secure Portable Hard Drive, Matthias Deeg found out that the firmware of the USB-to-SATA bridge controller INIC-3637EN uses AES-256 with the ECB (Electronic Codebook) mode. This operation mode of block ciphers like AES encrypts identical plaintext data, in this case blocks of 16 bytes, always to identical ciphertext data. For some data, for instance bitmap images, the lack of the cryptographic property called diffusion concerning the ECB mode can leak sensitive information even in encrypted data.

When analyzing the Verbatim Fingerprint Secure Portable Hard Drive, Matthias Deeg found out it uses an insecure design which allows retrieving the currently used password and thus the ability to unlock and access the stored data in an unauthorized way.

Red Hat Security Advisory 2022-5096-01 - The grub2 packages provide version 2 of the Grand Unified Boot Loader, a highly configurable and customizable boot loader with modular architecture. The packages support a variety of kernel formats, file systems, computer architectures, and hardware devices. The shim package contains a first-stage UEFI boot loader that handles chaining to a trusted full boot loader under secure boot environments. Issues addressed include buffer overflow, out of bounds write, and use-after-free vulnerabilities.

Red Hat Security Advisory 2022-5052-01 - XZ Utils is an integrated collection of user-space file compression utilities based on the Lempel-Ziv-Markov chain algorithm, which performs lossless data compression. The algorithm provides a high compression ratio while keeping the decompression time short.
