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." } ] }, "impact": { "cvss": { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 7.7, "baseSeverity": "HIGH", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "CHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H", "version": "3.1" } }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "{\"CWE-400\":\"Uncontrolled Resource Consumption\"}" } ] } ] }, "references": { "reference_data": [ { "name": "https://github.com/etcd-io/etcd/security/advisories/GHSA-2xhq-gv6c-p224", "refsource": "CONFIRM", "url": "https://github.com/etcd-io/etcd/security/advisories/GHSA-2xhq-gv6c-p224" }, { "refsource": "FEDORA", "name": "FEDORA-2020-cd43b84c16", "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/L6B6R43Y7M3DCHWK3L3UVGE2K6WWECMP/" } ] }, "source": { "advisory": "GHSA-2xhq-gv6c-p224", "discovery": "UNKNOWN" } }
