{"cve":"CVE-2025-25188","nvd":{"published":"2025-02-10T18:15:35.827","modified":"2026-06-17T09:00:26.990","status":"Deferred","description":"Hickory DNS is a Rust based DNS client, server, and resolver. A vulnerability present starting in version 0.8.0 and prior to versions 0.24.3 and 0.25.0-alpha.5 impacts Hickory DNS users relying on DNSSEC verification in the client library, stub resolver, or recursive resolver. The DNSSEC validation routines treat entire RRsets of DNSKEY records as trusted once they have established trust in only one of the DNSKEYs. As a result, if a zone includes a DNSKEY with a public key that matches a configured trust anchor, all keys in that zone will be trusted to authenticate other records in the zone. There is a second variant of this vulnerability involving DS records, where an authenticated DS record covering one DNSKEY leads to trust in signatures made by an unrelated DNSKEY in the same zone. Versions 0.24.3 and 0.25.0-alpha.5 fix the issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:P","score":5.7},"cvss_v3":null,"cwes":["CWE-345"],"references":["https://github.com/hickory-dns/hickory-dns/commit/e118c6eec569f4340421f86ee0686714010c63e9","https://github.com/hickory-dns/hickory-dns/security/advisories/GHSA-37wc-h8xc-5hc4"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:59:18.731010617+00:00"},"epss":{"cve":"CVE-2025-25188","score":0.00281,"percentile":0.207,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-37wc-h8xc-5hc4","url":"https://osv.dev/vulnerability/GHSA-37wc-h8xc-5hc4","summary":"Hickory DNS's DNSSEC validation may accept broken authentication chains","modified":"2026-09-10T03:50:56.480144645Z","packages":[{"ecosystem":"crates.io","name":"hickory-proto","purl":"pkg:cargo/hickory-proto","ranges":[">=0.8.0 <0.24.3"],"fixed":["0.24.3"]}]}],"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).
