NVD Description

Note: Versions mentioned in the description apply only to the upstream 389-ds-base-devel package and not the 389-ds-base-devel package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2 relevant fixed versions and status.

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.
