Overview
Affected versions of this package are vulnerable to Missing Authorization via the CleanAllRUV and Abort CleanAllRUV processes. An attacker can remove a replica's entry from replication metadata, purge changelog records, or interrupt an administrator's in-progress cleanup by sending crafted LDAP requests to the server. This is only exploitable if the attacker can reach the LDAP listener; with anonymous access enabled (the default), no authentication is required, but if restricted, any authenticated account can trigger the behavior regardless of privilege level.
Workaround
This vulnerability can be mitigated by setting nsslapd-allow-anonymous-access to rootdse or off, and by restricting replication LDAP ports to trusted networks.
