Cybersecurity: Vulnerabilities in CPSD CryptoPro Secure Disk for BitLocker
Multiple vulnerabilities have been identified in CryptoPro Secure Disk (CPSD) for BitLocker, an encryption solution employed by various organizations.
These vulnerabilities could allow attackers with physical access to devices to gain root access and potentially steal sensitive credentials.
CVE CVSS Details
CVE-2025-10010 N/A Integrity bypass enabling root code execution.
N/A N/A Cleartext /tmp data exposes credentials.
The vulnerability, identified as CVE-2025-10010, involves an integrity validation bypass. CryptoPro Secure Disk employs a minimal Linux operating system for authentication before decrypting the Windows partition using BitLocker.
This Linux system is located on an unencrypted partition, accessible to anyone with physical access to the hard drive or who can boot from an external medium.
Multiple vulnerabilities have been identified in CryptoPro Secure Disk (CPSD) for BitLocker, an encryption solution employed by various organizations.
While the system uses the Linux kernel's Integrity Measurement Architecture (IMA) for file verification, researchers found that IMA does not validate certain configuration files.
By manipulating these files, an attacker can execute arbitrary code with root privileges, allowing potential monitoring or data access without triggering errors.
Product Vulnerable Versions Fixed Versions
CPSD CryptoPro Secure Disk < 7.6.6 / < 7.7.1 7.6.6 / 7.7.1
The second issue involves the storage of sensitive data in clear text. When users forget their credentials, CryptoPro Secure Disk connects to a predefined network for support, storing necessary secrets such as certificates and passwords in cleartext within the temporary /tmp folder.
An attacker who gains access to the Linux environment could easily read these files, potentially compromising internal networks or bypassing network access controls.
The vendor was notified of these issues in June 2025. Patches addressing the vulnerabilities are available in versions 7.6.6 and 7.7.1.
Organizations using CryptoPro Secure Disk should update their software immediately. If updating is not feasible, encrypting the PBA partition is recommended, a feature available since version 7.6.0. From version 7.7, this encryption is enabled by default, reducing the risk of unauthorized file modifications.
SEC Consult advises comprehensive security reviews of encryption solutions to identify and mitigate potential weaknesses.
