Who should care
Defenders responsible for systems using CPSD CryptoPro Secure Disk for Bitlocker should assess exposure and prioritize patching to version 7.7.4 or later. This includes operators, platform administrators, vulnerability management teams, and security teams who need to ensure that LUKS encryption validation and file integrity checks are performed to prevent potential unauthorized access to sensitive data. The vulnerability affects systems using the CPSD 7.7
Why it matters
Defenders should prioritize patching to version 7.7.4 or later, verify LUKS encryption validation, and ensure file integrity checks are performed to prevent potential unauthorized access to sensitive data.
- Potential unauthorized access to sensitive data
- File integrity checks may be bypassed
- LUKS encryption validation may be compromised
Technical summary
CPSD CryptoPro Secure Disk for Bitlocker before v7.7.4 fails to properly validate LUKS encryption. If encryption is present, all CryptoPro file integrity checks are skipped, potentially allowing unauthorized access to sensitive data. The vulnerability has a CVSS score of 9.1 and is considered critical. Defenders should prioritize patching to version 7.7.4 or later, verify LUKS encryption validation, and ensure file integrity checks are performed to prevent potential unauthorized access to sensitive data. The affected product is CPSD CryptoPro Secure Disk for Bitlocker, and the vulnerability is related to LUKS encryption validation and file integrity checks.
Defensive priority
Defenders should prioritize patching to version 7.7.4 or later, verify LUKS encryption validation, and ensure file integrity checks are performed.
Recommended defensive actions
- Patch to version 7.7.4 or later
- Verify LUKS encryption validation
- Ensure file integrity checks are performed
- Review compensating controls for exposed systems while remediation is scheduled and verified
- Check relevant monitoring, detection, and logs for exposed assets that need extra review
- Track exceptions, retest remediated assets, and close the item only after evidence is documented
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
