{"id":"BIT-etcd-2020-15113","summary":"Improper Preservation of Permissions in etcd","details":"In etcd before versions 3.3.23 and 3.4.10, certain directory paths are created (etcd data directory and the directory path when provided to automatically generate self-signed certificates for TLS connections with clients) with restricted access permissions (700) by using the os.MkdirAll. This function does not perform any permission checks when a given directory path exists already. A possible workaround is to ensure the directories have the desired permission (700).","aliases":["CVE-2020-15113","GHSA-chh6-ppwq-jh92"],"modified":"2026-09-08T08:47:09.049634705Z","published":"2024-03-06T10:52:21.172Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:etcd:etcd:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://github.com/etcd-io/etcd/security/advisories/GHSA-chh6-ppwq-jh92"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L6B6R43Y7M3DCHWK3L3UVGE2K6WWECMP/"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15113"}],"affected":[{"package":{"name":"etcd","ecosystem":"Bitnami","purl":"pkg:bitnami/etcd"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.3.23"},{"introduced":"3.4.0"},{"fixed":"3.4.10"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/etcd/BIT-etcd-2020-15113.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}],"schema_version":"1.9.0"}
