Configuration disclosure via CleanAllRUV LDAP filter injection
Published Jul 31, 2026 · Updated Jul 31, 2026
LDAP injection in 389 Directory Server allows remote attackers to disclose sensitive configuration data without authentication. The CleanAllRUV status-check handler passes an attacker-controlled filter unchanged to an internal cn=config search under the replication plugin identity, then exposes matches through a boolean response. Anonymous LDAP access, enabled by default on susceptible Red Hat deployments, is sufficient; disclosed metadata includes replication bind DNs, storage schemes, paths, and ACI keywords, but not password hashes.
