Starting in version 1.2.0 and prior to version 1.12.4, the CoreDNS etcd plugin contains a TTL confusion vulnerability where lease IDs are incorrectly used as TTL values, enabling DNS cache pinning attacks. This effectively creates a DoS condition for DNS resolution of affected services. The `TTL()` function in `plugin/etcd/etcd.go` incorrectly casts etcd lease IDs (64-bit integers) to uint32 and uses them as TTL values. Large lease IDs become very large TTLs when cast to uint32. This enables cache pinning attacks. Version 1.12.4 contains a fix for the issue."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H","baseScore":7.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":4.2}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-681"}]}],"references":[{"url":"https://github.com/coredns/coredns/commit/e1768a5d272e9da649dfb8588595e5c6e4e640bf","source":"security-advisories@github.com"},{"url":"https://github.com/coredns/coredns/security/advisories/GHSA-93mf-426m-g6x9","source":"security-advisories@github.com"},{"url":"https://github.com/coredns/coredns/security/advisories/GHSA-93mf-426m-g6x9","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}}]}
