{"id":"GHSA-4993-m7g5-r9hh","summary":"etcd has no minimum password length","details":"### Vulnerability type\nAccess Control\n\n### Workarounds\nThe etcdctl and etcd API do not enforce a specific password length during user creation or user password update operations. [It is the responsibility of the administrator to enforce these requirements](https://github.com/etcd-io/etcd/blob/master/Documentation/op-guide/authentication.md#notes-on-password-strength).\n\n### Detail\netcd does not perform any password length validation, which allows for very short passwords, such as those with a length of one. This may allow an attacker to guess or brute-force users’ passwords with little computational effort.\n\n### References\nFind out more on this vulnerability in the [security audit report](https://github.com/etcd-io/etcd/blob/master/security/SECURITY_AUDIT.pdf)\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Contact the [etcd security committee](https://github.com/etcd-io/etcd/blob/master/security/security-release-process.md#product-security-committee-psc)","aliases":["CVE-2020-15115"],"modified":"2026-05-07T05:01:00.575188497Z","published":"2022-10-06T23:14:23Z","database_specific":{"nvd_published_at":"2020-08-06T22:15:00Z","cwe_ids":["CWE-521"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2022-10-06T23:14:23Z"},"references":[{"type":"WEB","url":"https://github.com/etcd-io/etcd/security/advisories/GHSA-4993-m7g5-r9hh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15115"},{"type":"PACKAGE","url":"https://github.com/etcd-io/etcd"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/L6B6R43Y7M3DCHWK3L3UVGE2K6WWECMP"}],"affected":[{"package":{"name":"go.etcd.io/etcd/client/v3","ecosystem":"Go","purl":"pkg:golang/go.etcd.io/etcd/client/v3"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.4.0"},{"fixed":"3.4.10"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/10/GHSA-4993-m7g5-r9hh/GHSA-4993-m7g5-r9hh.json"}},{"package":{"name":"go.etcd.io/etcd/client/v3","ecosystem":"Go","purl":"pkg:golang/go.etcd.io/etcd/client/v3"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.3.23"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/10/GHSA-4993-m7g5-r9hh/GHSA-4993-m7g5-r9hh.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N"}]}
