{"id":"GHSA-2xhq-gv6c-p224","summary":"Etcd Gateway can include itself as an endpoint resulting in resource exhaustion","details":"### Vulnerability type\nDenial of Service\n\n### Detail\nThe etcd gateway is a simple TCP proxy to allow for basic service discovery and access. However, it is possible to include the gateway address as an endpoint. This results in a denial of service, since the endpoint can become stuck in a loop of requesting itself until there are no more available file descriptors to accept connections on the gateway.\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-2020-15114"],"modified":"2026-07-17T21:05:57.507981088Z","published":"2024-01-31T00:21:52Z","database_specific":{"nvd_published_at":"2020-08-06T23:15:00Z","cwe_ids":["CWE-400","CWE-772"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2024-01-31T00:21:52Z"},"references":[{"type":"WEB","url":"https://github.com/etcd-io/etcd/security/advisories/GHSA-2xhq-gv6c-p224"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15114"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/L6B6R43Y7M3DCHWK3L3UVGE2K6WWECMP"}],"affected":[{"package":{"name":"go.etcd.io/etcd","ecosystem":"Go","purl":"pkg:golang/go.etcd.io/etcd"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.4.0-rc.0"},{"fixed":"3.4.10"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/01/GHSA-2xhq-gv6c-p224/GHSA-2xhq-gv6c-p224.json","last_known_affected_version_range":"\u003c= 3.4.9"}},{"package":{"name":"go.etcd.io/etcd","ecosystem":"Go","purl":"pkg:golang/go.etcd.io/etcd"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.3.23"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/01/GHSA-2xhq-gv6c-p224/GHSA-2xhq-gv6c-p224.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H"}]}
