{"id":"GHSA-43fp-vwwg-qgv6","summary":"Apache NiFi Improper Input Validation vulnerability","details":"When a client request to a cluster node was replicated to other nodes in the cluster for verification, the Content-Length was forwarded. On a DELETE request, the body was ignored, but if the initial request had a Content-Length value other than 0, the receiving nodes would wait for the body and eventually timeout. Mitigation: The fix to check DELETE requests and overwrite non-zero Content-Length header values was applied on the Apache NiFi 1.8.0 release. Users running a prior 1.x release should upgrade to the appropriate release.","aliases":["CVE-2018-17194"],"modified":"2024-03-04T21:49:21.756507Z","published":"2018-12-20T22:02:32Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2020-06-16T20:57:07Z","nvd_published_at":null,"cwe_ids":["CWE-20"],"severity":"HIGH"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-17194"},{"type":"WEB","url":"https://github.com/apache/nifi/commit/1baead6f525046a613fc4fe494a0d193776ea70f"},{"type":"WEB","url":"https://github.com/apache/nifi/commit/748cf745628dab20b7e71f12b5dcfe6ed0bbf134"},{"type":"PACKAGE","url":"https://github.com/apache/nifi"},{"type":"WEB","url":"https://issues.apache.org/jira/browse/NIFI-5628"},{"type":"WEB","url":"https://nifi.apache.org/security.html#CVE-2018-17194"}],"affected":[{"package":{"name":"org.apache.nifi:nifi-framework-cluster","ecosystem":"Maven","purl":"pkg:maven/org.apache.nifi/nifi-framework-cluster"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.0"},{"fixed":"1.8.0"}]}],"versions":["1.0.0","1.0.1","1.1.0","1.1.1","1.1.2","1.2.0","1.3.0","1.4.0","1.5.0","1.6.0","1.7.0","1.7.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2018/12/GHSA-43fp-vwwg-qgv6/GHSA-43fp-vwwg-qgv6.json","last_known_affected_version_range":"\u003c= 1.7.1"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
