Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

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.
