{"id":"CVE-2019-13565","url":"https://www.cyber-defence.io/tools/cve/CVE-2019-13565","generatedAt":"2026-10-29T02:05:11.499Z","title":"An issue was discovered in OpenLDAP 2.x before 2.4.48.","description":"An issue was discovered in OpenLDAP 2.x before 2.4.48. When using SASL authentication and session encryption, and relying on the SASL security layers in slapd access controls, it is possible to obtain access that would otherwise be denied via a simple bind for any identity covered in those ACLs. After the first SASL bind is completed, the sasl_ssf value is retained for all new non-SASL connections. Depending on the ACL configuration, this can affect different types of operations (searches, modifications, etc.). In other words, a successful authorization step completed by one user affects the authorization requirement for a different user.","published":"2019-07-26T13:15:13.000Z","lastModified":"2026-10-14T07:16:46.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":[],"affected":["openldap/openldap","canonical/ubuntu linux","debian/debian linux","opensuse/leap","f5/traffix signaling delivery controller","apple/mac os x","oracle/blockchain platform","oracle/zfs storage appliance kit","oracle/solaris"],"epss":{"score":0.05015,"percentile":0.92207,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (5.01%).
