{"cve":"CVE-2024-5971","nvd":{"published":"2024-07-08T21:15:12.480","modified":"2026-09-04T15:17:27.827","status":"Deferred","description":"A vulnerability was found in Undertow, where the chunked response hangs after the body was flushed. The response headers and body were sent but the client would continue waiting as Undertow does not send the expected 0\\r\\n termination of the chunked response. This results in uncontrolled resource consumption, leaving the server side to a denial of service attack. This happens only with Java 17 TLSv1.3 scenarios.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-674"],"references":["https://access.redhat.com/errata/RHSA-2024:4392","https://access.redhat.com/errata/RHSA-2024:4884","https://access.redhat.com/errata/RHSA-2024:5143","https://access.redhat.com/errata/RHSA-2024:5144","https://access.redhat.com/errata/RHSA-2024:5145"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:52:42.518321223+00:00"},"epss":{"cve":"CVE-2024-5971","score":0.02921,"percentile":0.87042,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-xpp6-8r3j-ww43","url":"https://osv.dev/vulnerability/GHSA-xpp6-8r3j-ww43","summary":"Undertow Denial of Service vulnerability","modified":"2024-09-30T20:08:28.287073Z","packages":[{"ecosystem":"Maven","name":"io.undertow:undertow-core","purl":"pkg:maven/io.undertow/undertow-core","ranges":[">=2.3.0.Alpha1 <2.3.15.Final"],"fixed":["2.3.15.Final"]},{"ecosystem":"Maven","name":"io.undertow:undertow-core","purl":"pkg:maven/io.undertow/undertow-core","ranges":["<2.2.34.Final"],"fixed":["2.2.34.Final"]}]}],"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).
