Detailsinfo

A vulnerability, which was classified as critical, has been found in CPSD IT Services CryptoPro Secure Disk for BitLocker up to 7.6.5 /7.7.0. This issue affects an unknown functionality of the component Configuration File Handler. The manipulation with an unknown input leads to a integrity check vulnerability. Using CWE to declare the problem leads to CWE-353. The product uses a transmission protocol that does not include a mechanism for verifying the integrity of the data during transmission, such as a checksum. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The CPSD CryptoPro Secure Disk application boots a small Linux operating system to perform user authentication before using BitLocker to decrypt the Windows partition. The system is located on a separate unencrypted partition which can be reached by anyone with access to the hard disk. Multiple checks are performed to validate the integrity of the Linux operating system and the CryptoPro Secure Disk application files. When files are changed an error is shown on system start. One of the checks is the Linux kernel's Integrity Measurement Architecture (IMA). It was identified that configuration files are not validated by the IMA and can then (if not checked by other measures) be changed. This allows an attacker to execute arbitrary code in the context of the root user and enables an attacker to e.g., plant a backdoor and access data during execution.

The weakness was disclosed by Gorazd Jank. The advisory is shared at r.sec-consult.com. The identification of this vulnerability is CVE-2025-10010 since 09/05/2025. The exploitation is known to be difficult. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available.

Upgrading to version 7.6.6 or 7.7.1 eliminates this vulnerability.
