CVE-2025-59319: CPSD CryptoPro Secure Disk for Bitlocker before v7.7.4 fails to certify the integrity of the intended boot...
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.
Security readout for executives and security teams
Plain-English summary
CryptoPro Secure Disk for BitLocker before version 7.7.4 may trust the wrong boot partition. An attacker who already has high privileges could place a crafted Linux partition before the intended partition, causing privileged attacker-controlled code to run. Successful exploitation could compromise confidentiality, integrity, and availability.
Executive priority
Treat as a high-priority hardening and upgrade issue on affected endpoints. Immediate emergency action is not supported by current exploitation evidence, but privileged code execution could cause complete system compromise. Accelerate inventory and remediation wherever administrators, compromised privileged accounts, or management tooling can alter partitions.
Technical view
The product identifies the boot target by selecting the first partition whose type matches a hardcoded value, without certifying that partition is the intended trusted target. A crafted Linux partition positioned earlier can therefore be selected and execute code with high privilege. CVSS 3.1 rates this 7.2: network-accessible, low complexity, high privileges required, and no user interaction.
Likely exposure
Exposure is limited to deployments running CryptoPro Secure Disk for BitLocker versions earlier than 7.7.4. Risk is greatest where a privileged attacker can alter disk partition layout. The supplied affected-product metadata is incomplete, so organizations should confirm precise platform and version applicability with CPSD.
Exploitation context
The supplied record is not in CISA KEV and provides no evidence of active exploitation. Exploitation requires high privileges but can yield high-impact privileged code execution without user interaction. Public Black Hat presentation materials discuss the research; the bundle does not establish weaponized exploit availability.
Researcher notes
The core issue is inadequate boot-partition identity validation combined with first-match selection using a hardcoded partition type. The CVSS vector requires high privileges despite network attack-vector scoring. CWE-290 is assigned. Product metadata contains placeholders, and the bundle does not document affected operating systems, attack prerequisites beyond privileges, patch internals, or exploitation telemetry.
Mitigation direction
Inventory CryptoPro Secure Disk for BitLocker installations and identify versions earlier than 7.7.4.
Prioritize upgrading affected systems to version 7.7.4 or later, subject to CPSD guidance.
Restrict privileged access capable of modifying disk partitions or boot configuration.
Review CPSD guidance for additional mitigations, deployment prerequisites, and supported upgrade paths.
Validation and detection
Confirm installed product versions through trusted software inventory records.
Verify upgraded systems report version 7.7.4 or later.
Inspect partition layouts for unexpected Linux partitions preceding the intended boot target.
Confirm boot and encryption workflows operate correctly after remediation.
Recheck CPSD guidance for clarified affected configurations or validation procedures.
