CPSD CryptoPro Secure Disk vulnerabilities

CPSD CryptoPro Secure Disk for Bitlocker before v7.7.4 fails to properly validate LUKS encryption and, if encryption is present, all CryptoPro file integrity checks are skipped.

CPSD CryptoPro Secure Disk for Bitlocker before v7.7.4 contains a default TPM PCR policy that fails to consider the system boot state. This allows the TPM to be unsealed via an unintended execution path or from another hardware platform.

CPSD CryptoPro Secure Disk for Bitlocker before v7.7.4 fails to enforce IMA policy protections across temporary file systems, allowing for unsigned code to be executed from these locations.

CPSD CryptoPro Secure Disk for Bitlocker before v7.7.4 fails to validate the integrity of the DataStore, a non-partitioned filesystem, responsible for storing configuration and cryptographic details. Crafted DataStore contents can impact service availability and/or allow for code execution in the context of high privilege.

CPSD CryptoPro Secure Disk for Bitlocker before v7.7.4 fails to properly handle decryption errors and allows encrypted volumes to be mounted as plaintext.

CPSD CryptoPro Secure Disk for Bitlocker before v7.7.4 stores TPM2.0 secrets in a serialized format within unused disk sectors. An unauthenticated attacker with physical access to the system disk can recover this information and craft an environment to unseal the TPM.

CPSD CryptoPro Secure Disk for Bitlocker before v7.7.4 fails to certify the integrity of the intended boot partition and selects the first partition index matching a hardcoded type value. A crafted Linux partition could be inserted ahead of this intended target, allowing for code execution in the context of high privilege.

In CPSD CryptoPro Secure Disk for Bitlocker before v7.7.4, bootxsa.efi fails to properly validate LUKS encryption and, if encryption is present, all CryptoPro file integrity checks are skipped.

CPSD CryptoPro Secure Disk for Bitlocker before v7.7.4 fails to encrypt the initramfs contents, allowing for the offline recovery of secrets and cryptographic details.
