It allows use of an external user/group database stored in LDAP. The connection configuration allows the usage of unencrypted, SSL- or TLS-secured connections. Unfortunately, the Graylog client code (in all versions that support LDAP) does not implement proper certificate validation (regardless of whether the \"Allow self-signed certificates\" option is used). Therefore, any attacker with the ability to intercept network traffic between a Graylog server and an LDAP server is able to redirect traffic to a different LDAP server (unnoticed by the Graylog server due to the lack of certificate validation), effectively bypassing Graylog's authentication mechanism.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2020-15813","reference_id":"","reference_type":"","scores":[{"value":"0.00192","scoring_system":"epss","scoring_elements":"0.40961","published_at":"2026-06-09T12:55:00Z"},{"value":"0.00192","scoring_system":"epss","scoring_elements":"0.40932","published_at":"2026-06-04T12:55:00Z"},{"value":"0.00192","scoring_system":"epss","scoring_elements":"0.41008","published_at":"2026-06-05T12:55:00Z"},{"value":"0.00192","scoring_system":"epss","scoring_elements":"0.41013","published_at":"2026-06-06T12:55:00Z"},{"value":"0.00192","scoring_system":"epss","scoring_elements":"0.40981","published_at":"2026-06-07T12:55:00Z"},{"value":"0.00192","scoring_system":"epss","scoring_elements":"0.4095","published_at":"2026-06-08T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2020-15813"},{"reference_url":"https://github.com/Graylog2/graylog2-server/issues/5906","reference_id":"","reference_type":"","scores":[{"value":"8.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/Graylog2/graylog2-server/issues/5906"},{"reference_url":"https://github.com/Graylog2/graylog2-server/pull/8569","reference_id":"","reference_type":"","scores":[{"value":"8.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/Graylog2/graylog2-server/pull/8569"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15813","reference_id":"CVE-2020-15813","reference_type":"","scores":[{"value":"8.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15813"},{"reference_url":"https://github.com/advisories/GHSA-3gg9-f3vh-866f","reference_id":"GHSA-3gg9-f3vh-866f","reference_type":"","scores":[{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""}],"url":"https://github.com/advisories/GHSA-3gg9-f3vh-866f"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/60605?format=json","purl":"pkg:maven/org.graylog/graylog-parent@3.3.3","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:maven/org.graylog/graylog-parent@3.3.3"}],"aliases":["CVE-2020-15813","GHSA-3gg9-f3vh-866f"],"risk_score":4.0,"exploitability":"0.5","weighted_severity":"8.0","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-y9c9-hs82-wych"}],"fixing_vulnerabilities":[],"risk_score":"4.0","resource_url":"http://public2.vulnerablecode.io/packages/pkg:maven/org.graylog/graylog-parent@3.2.0"}
