CVE-2025-59322 Aug 12, 00:00 HIGH This Week

CryptoPro Secure Disk for BitLocker before v7.7.4 silently falls back to plaintext volume mounting when a decryption error occurs, negating the entire confidentiality guarantee that BitLocker is meant to enforce. Disclosed publicly at Black Hat USA 2026 in research titled 'The Cost of Obscurity' (Burch), the flaw demonstrates how improper error handling in encryption middleware can fully undermine the security layer it wraps. No public exploit code has been identified at time of analysis, though the Black Hat presentation and accompanying whitepaper are publicly available, substantially lowering the knowledge barrier for exploitation; EPSS stands at a low 0.17% but may shift as presentation details circulate.

CVE-2026-14969 Jul 07, 15:48 MEDIUM This Month

Attribute encryption in the 389-ds-base LDBM backend exposes a cryptographic design flaw affecting Red Hat Directory Server 11, 12, and 13 across all supported RHEL releases (6 through 10). The LDBM backend applies a static, hardcoded initialization vector (IV) for both AES-CBC and 3DES-CBC encryption of directory attribute values, meaning that two entries storing identical plaintext for an encrypted attribute will always produce identical ciphertext blocks - a classic ciphertext equality oracle. An attacker with privileged filesystem-level read access to the LDBM database files can exploit this to determine whether any two encrypted attribute values are identical, leaking relational information about the directory without recovering plaintext. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA KEV catalog.
