{"id":"GHSA-qq3j-44gw-cf6r","summary":"Eclipse Californium denial of service (DoS) via Datagram Transport Layer Security (DTLS) handshake on parameter mismatch","details":"In Eclipse Californium versions 2.0.0 to 2.7.2 and 3.0.0-3.5.0 a DTLS resumption handshake falls back to a DTLS full handshake on a parameter mismatch without using a HelloVerifyRequest. Especially, if used with certificate based cipher suites, that results in message amplification (DDoS other peers) and high CPU load (DoS own peer). The misbehavior occurs only with DTLS_VERIFY_PEERS_ON_RESUMPTION_THRESHOLD values larger than 0.","aliases":["CVE-2022-2576"],"modified":"2023-11-01T04:58:20.120162Z","published":"2022-07-30T00:00:35Z","database_specific":{"cwe_ids":["CWE-408"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2022-08-10T15:41:24Z","nvd_published_at":"2022-07-29T14:15:00Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-2576"},{"type":"WEB","url":"https://github.com/eclipse-californium/californium/pull/2039"},{"type":"WEB","url":"https://github.com/eclipse-californium/californium/commit/0cc953a1dc071efc960130e229fcb4f8bda7f9df"},{"type":"WEB","url":"https://github.com/eclipse-californium/californium/commit/8373db84b2d07f22c39ffc333ab881dba9401722"},{"type":"WEB","url":"https://bugs.eclipse.org/580018"},{"type":"PACKAGE","url":"https://github.com/eclipse/californium"}],"affected":[{"package":{"name":"org.eclipse.californium:californium-core","ecosystem":"Maven","purl":"pkg:maven/org.eclipse.californium/californium-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.0.0"},{"fixed":"2.7.3"}]}],"versions":["2.0.0","2.1.0","2.1.0-RC1","2.1.0-RC2","2.2.0","2.2.0-RC1","2.2.1","2.2.2","2.2.3","2.3.0","2.3.0-RC1","2.3.0-RC2","2.3.1","2.4.0","2.4.1","2.5.0","2.6.0","2.6.1","2.6.2","2.6.3","2.6.4","2.6.5","2.6.6","2.7.0","2.7.1","2.7.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/07/GHSA-qq3j-44gw-cf6r/GHSA-qq3j-44gw-cf6r.json","last_known_affected_version_range":"\u003c= 2.7.2"}},{"package":{"name":"org.eclipse.californium:californium-core","ecosystem":"Maven","purl":"pkg:maven/org.eclipse.californium/californium-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"3.6.0"}]}],"versions":["3.0.0","3.1.0","3.2.0","3.3.0","3.3.1","3.4.0","3.5.0"],"database_specific":{"last_known_affected_version_range":"\u003c= 3.5.0","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/07/GHSA-qq3j-44gw-cf6r/GHSA-qq3j-44gw-cf6r.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
