CVE-2018-14628Network attack vector

Authenticated deleted-object disclosure via inherited permissions

Published Jan 17, 2023 · Updated Feb 13, 2025

Information disclosure in Samba 4.0.0 and later allows remote authenticated users to read deleted-object names and preserved attributes over LDAP. The Deleted Objects container inherits the domain or partition head ntSecurityDescriptor instead of receiving restrictive permissions, so LDAP_SERVER_SHOW_DELETED_OID exposes tombstones. Exploitation requires an unprivileged account and a Samba AD domain controller provisioned with the permissive descriptor; disclosure is limited to names and attributes retained after deletion.
