{"id":"UBUNTU-CVE-2026-11770","details":"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.","modified":"2026-08-06T00:12:14Z","published":"2026-07-31T10:16:00Z","upstream":["CVE-2026-11770"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-11770"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-11770"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2484802"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2026-11770"},{"type":"REPORT","url":"https://github.com/389ds/389-ds-base/blob/main/ldap/servers/plugins/replication/repl_extop.c"}],"affected":[{"package":{"name":"389-ds-base","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/389-ds-base?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.3.12-1build1","1.3.3.13-1","1.3.4.5-2","1.3.4.8-1","1.3.4.8-3","1.3.4.8-3ubuntu1","1.3.4.8-4","1.3.4.9-1","1.3.4.9-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"389-ds","binary_version":"1.3.4.9-1ubuntu0.1~esm1"},{"binary_name":"389-ds-base","binary_version":"1.3.4.9-1ubuntu0.1~esm1"},{"binary_name":"389-ds-base-libs","binary_version":"1.3.4.9-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-11770.json"}},{"package":{"name":"389-ds-base","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/389-ds-base?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.7.5-1","1.3.7.5-1build1","1.3.7.5-1build2","1.3.7.9-1","1.3.7.10-1","1.3.7.10-1ubuntu1","1.3.7.10-1ubuntu1+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"389-ds","binary_version":"1.3.7.10-1ubuntu1+esm1"},{"binary_version":"1.3.7.10-1ubuntu1+esm1","binary_name":"389-ds-base"},{"binary_name":"389-ds-base-libs","binary_version":"1.3.7.10-1ubuntu1+esm1"},{"binary_name":"python3-dirsrvtests","binary_version":"1.3.7.10-1ubuntu1+esm1"},{"binary_name":"python3-lib389","binary_version":"1.3.7.10-1ubuntu1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-11770.json"}},{"package":{"name":"389-ds-base","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/389-ds-base?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.1.6-4","1.4.1.6-4build1","1.4.2.4-1","1.4.2.4-1build1","1.4.3.2-1","1.4.3.2-1build1","1.4.3.6-2","1.4.3.6-2ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"389-ds","binary_version":"1.4.3.6-2ubuntu0.1~esm1"},{"binary_version":"1.4.3.6-2ubuntu0.1~esm1","binary_name":"389-ds-base"},{"binary_name":"389-ds-base-libs","binary_version":"1.4.3.6-2ubuntu0.1~esm1"},{"binary_name":"cockpit-389-ds","binary_version":"1.4.3.6-2ubuntu0.1~esm1"},{"binary_name":"python3-lib389","binary_version":"1.4.3.6-2ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-11770.json"}},{"package":{"name":"389-ds-base","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/389-ds-base?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.4.11-2build1","1.4.4.11-2build2","1.4.4.17-1","2.0.11-2","2.0.14-1","2.0.15-1","2.0.15-1ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.0.15-1ubuntu2","binary_name":"389-ds"},{"binary_name":"389-ds-base","binary_version":"2.0.15-1ubuntu2"},{"binary_name":"389-ds-base-libs","binary_version":"2.0.15-1ubuntu2"},{"binary_version":"2.0.15-1ubuntu2","binary_name":"cockpit-389-ds"},{"binary_name":"python3-lib389","binary_version":"2.0.15-1ubuntu2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-11770.json"}},{"package":{"name":"389-ds-base","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/389-ds-base?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3.4+dfsg1-1","2.4.4+dfsg1-1ubuntu1","2.4.4+dfsg1-1ubuntu4","2.4.4+dfsg1-3","2.4.5+dfsg1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"389-ds","binary_version":"2.4.5+dfsg1-1"},{"binary_name":"389-ds-base","binary_version":"2.4.5+dfsg1-1"},{"binary_name":"389-ds-base-libs","binary_version":"2.4.5+dfsg1-1"},{"binary_version":"2.4.5+dfsg1-1","binary_name":"cockpit-389-ds"},{"binary_name":"python3-lib389","binary_version":"2.4.5+dfsg1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-11770.json"}},{"package":{"name":"389-ds-base","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/389-ds-base?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.2+dfsg1-1","3.1.2+vendor1-2"],"ecosystem_specific":{"binaries":[{"binary_version":"3.1.2+vendor1-2","binary_name":"389-ds"}
