CVE-2025-59323 in Secure Disk for BitLocker
Summary
by MITRE • 08/12/2026
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.

The vulnerability in CPSD CryptoPro Secure Disk for BitLocker versions prior to v7.7.4 represents a critical security flaw that undermines the integrity verification mechanisms essential for protecting encrypted data storage systems. This issue stems from the software's failure to properly validate the DataStore component, which serves as a non-partitioned filesystem containing crucial configuration parameters and cryptographic information necessary for BitLocker encryption operations. The DataStore functions as a central repository where encryption keys, volume metadata, and system configuration settings are stored, making it a prime target for exploitation attempts that could compromise the entire encryption framework.
The technical flaw manifests in the absence of proper input validation and integrity checks within the DataStore processing pipeline. When crafted malicious content is introduced into the DataStore, the system fails to verify the authenticity and consistency of this data before proceeding with cryptographic operations. This vulnerability creates a pathway for attackers to manipulate the underlying configuration parameters that govern BitLocker encryption behavior. The lack of validation allows adversaries to inject malformed or specially crafted data structures that can trigger unexpected behaviors within the encryption software, potentially leading to denial of service conditions or more severe exploitation vectors.
The operational impact of this vulnerability extends beyond simple service disruption to encompass potential privilege escalation and arbitrary code execution capabilities. Attackers exploiting this flaw can manipulate the DataStore contents to influence how BitLocker processes encryption keys and volume information, potentially gaining unauthorized access to encrypted data or compromising the integrity of the entire encryption system. The high-privilege execution context represents a particularly concerning aspect since it allows attackers to operate with elevated permissions that could enable them to bypass normal security boundaries and access sensitive system resources.
This vulnerability aligns with CWE-20, which addresses "Improper Input Validation" and demonstrates how inadequate data validation can lead to cascading security issues throughout cryptographic systems. The flaw also corresponds to ATT&CK technique T1059.007 for "Command and Scripting Interpreter: Python," as attackers could leverage the compromised DataStore to execute malicious code through legitimate system interfaces. Organizations deploying CPSD CryptoPro Secure Disk for BitLocker must recognize that this vulnerability affects core cryptographic functions and could potentially allow adversaries to undermine the fundamental security guarantees provided by BitLocker encryption.
The mitigation strategy should prioritize immediate deployment of version 7.7.4 or later, which includes proper DataStore integrity validation mechanisms. System administrators should implement monitoring solutions to detect anomalous DataStore modifications and establish regular integrity checks for cryptographic configuration components. Additional defensive measures include restricting access permissions to the DataStore, implementing network segmentation to limit exposure, and conducting thorough security assessments of all encryption-related systems to identify potential exploitation vectors. The vulnerability serves as a reminder of the critical importance of maintaining up-to-date cryptographic software and implementing robust validation controls in security-critical applications that handle sensitive data encryption operations.
