An attacker controlling an unsigned delegation whose name differs from a signed target only in dot positions can prime an Insecure verdict, causing forged answers for the target to skip signature verification instead of returning SERVFAIL.","cvssScore":5.9,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-1025"],"vendors":[],"products":[],"references":[{"url":"https://github.com/hickory-dns/hickory-dns/security/advisories/GHSA-rx82-4p2j-j5cv","tags":[]},{"url":"https://www.vulncheck.com/advisories/hickory-dns-0.26.0-beta.1-before-0.26.2-dnssec-validation-bypass-via-name-hash-collision","tags":[]}],"exploitRefs":[{"url":"https://github.com/hickory-dns/hickory-dns/security/advisories/GHSA-rx82-4p2j-j5cv","tags":[]}],"hasPoc":true,"ai":null}
