{"id":"UBUNTU-CVE-2019-13057","details":"An issue was discovered in the server in OpenLDAP before 2.4.48. When the server administrator delegates rootDN (database admin) privileges for certain databases but wants to maintain isolation (e.g., for multi-tenant deployments), slapd does not properly stop a rootDN from requesting authorization as an identity from another database during a SASL bind or with a proxyAuthz (RFC 4370) control. (It is not a common configuration to deploy a system where the server administrator and a DB administrator enjoy different levels of trust.)","modified":"2026-04-22T13:31:23.638681Z","published":"2019-07-26T00:00:00Z","related":["USN-4078-1","USN-4078-2"],"upstream":["CVE-2019-13057"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-13057"},{"type":"REPORT","url":"https://www.openldap.org/lists/openldap-announce/201907/msg00001.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4078-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4078-2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-13057"}],"affected":[{"package":{"name":"openldap","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/openldap@2.4.31-1+nmu2ubuntu8.5+esm1?arch=source&distro=trusty/esm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.31-1+nmu2ubuntu8.5+esm1"}]}],"versions":["2.4.31-1+nmu2ubuntu3","2.4.31-1+nmu2ubuntu4","2.4.31-1+nmu2ubuntu5","2.4.31-1+nmu2ubuntu8","2.4.31-1+nmu2ubuntu8.1","2.4.31-1+nmu2ubuntu8.2","2.4.31-1+nmu2ubuntu8.3","2.4.31-1+nmu2ubuntu8.4","2.4.31-1+nmu2ubuntu8.5"],"ecosystem_specific":{"binaries":[{"binary_version":"2.4.31-1+nmu2ubuntu8.5+esm1","binary_name":"ldap-utils"},{"binary_version":"2.4.31-1+nmu2ubuntu8.5+esm1","binary_name":"libldap-2.4-2"},{"binary_version":"2.4.31-1+nmu2ubuntu8.5+esm1","binary_name":"slapd"},{"binary_version":"2.4.31-1+nmu2ubuntu8.5+esm1","binary_name":"slapd-smbk5pwd"}],"availability":"Available with Ubuntu Pro (Infra-only): https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-13057.json"}},{"package":{"name":"openldap","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/openldap@2.4.42+dfsg-2ubuntu3.6?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.42+dfsg-2ubuntu3.6"}]}],"versions":["2.4.41+dfsg-1ubuntu2","2.4.41+dfsg-1ubuntu3","2.4.42+dfsg-2ubuntu1","2.4.42+dfsg-2ubuntu3","2.4.42+dfsg-2ubuntu3.1","2.4.42+dfsg-2ubuntu3.2","2.4.42+dfsg-2ubuntu3.3","2.4.42+dfsg-2ubuntu3.4","2.4.42+dfsg-2ubuntu3.5"],"ecosystem_specific":{"binaries":[{"binary_version":"2.4.42+dfsg-2ubuntu3.6","binary_name":"ldap-utils"},{"binary_version":"2.4.42+dfsg-2ubuntu3.6","binary_name":"libldap-2.4-2"},{"binary_version":"2.4.42+dfsg-2ubuntu3.6","binary_name":"slapd"},{"binary_version":"2.4.42+dfsg-2ubuntu3.6","binary_name":"slapd-smbk5pwd"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-13057.json"}},{"package":{"name":"openldap","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/openldap@2.4.45+dfsg-1ubuntu1.3?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.45+dfsg-1ubuntu1.3"}]}],"versions":["2.4.45+dfsg-1ubuntu1","2.4.45+dfsg-1ubuntu1.1","2.4.45+dfsg-1ubuntu1.2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.4.45+dfsg-1ubuntu1.3","binary_name":"ldap-utils"},{"binary_version":"2.4.45+dfsg-1ubuntu1.3","binary_name":"libldap-2.4-2"},{"binary_version":"2.4.45+dfsg-1ubuntu1.3","binary_name":"libldap-common"},{"binary_version":"2.4.45+dfsg-1ubuntu1.3","binary_name":"slapd"},{"binary_version":"2.4.45+dfsg-1ubuntu1.3","binary_name":"slapd-smbk5pwd"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-13057.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N"},{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"low"}]}
