389-ds-base: 389-ds-base: static initialization vector in aes-cbc/3des-cbc attribute encryption

publishedCWE-329

A flaw was found in 389-ds-base where the LDBM backend attribute encryption uses a hardcoded static initialization vector for AES-CBC and 3DES-CBC operations, allowing an attacker with privileged filesystem access to detect plaintext equality across encrypted entries by comparing ciphertext blocks.

Fixes and workarounds

Workaround

Disable attribute encryption if it is not required for the deployment. If attribute encryption is required, restrict filesystem access to the LDBM database directory (/var/lib/dirsrv/slapd-<instance>/db/) to ensure only authorized administrators can read database files.
