389-ds-base: 389-ds-base: pre-auth ldap filter injection in cleanallruv status check

State: Published
Severity: 7.5 High
Published: Jul 31, 2026
Updated: Oct 8, 2026
Reserved: Jun 9, 2026

Description

A flaw was found in 389 Directory Server. An unauthenticated remote attacker can inject LDAP search filters into the CleanAllRUV replication status-check extended operation. Because the handler performs the search against cn=config with elevated replication plugin privileges and returns a boolean match result, the attacker can extract sensitive server configuration metadata, including replication bind DNs and password storage scheme information.
