A revoked domain name can still be resolvable for a long time, including expired domains and taken-down malicious domains. The effects of an exploit would be widespread and highly impactful, because the exploitation conforms to de facto DNS specifications and operational practices, and overcomes current mitigation patches for \"Ghost\" domain names.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-672"],"references":["https://lists.debian.org/debian-lts-announce/2023/06/msg00019.html","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3VSMLJX25MXGQ6A7UPOGK7VPUVDESPHL/","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NB7LDZM5AGWC5BHHQHW6CP5OFNBBKFOQ/","https://maradns.samiam.org/","https://maradns.samiam.org/security.html#CVE-2022-30256"],"products":["maradns:maradns"],"source":"nvd","synced_at":"2026-10-19T21:37:28.463369388+00:00"},"epss":{"cve":"CVE-2022-30256","score":0.00968,"percentile":0.6183,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
