{"schemaVersion":3,"id":"CVE-2024-34362","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Envoy is a cloud-native, open source edge and service proxy. There is a use-after-free in `HttpConnectionManager` (HCM) with `EnvoyQuicServerStream` that can crash Envoy. An attacker can exploit this vulnerability by sending a request without `FIN`, then a `RESET_STREAM` frame, and then after receiving the response, closing the connection.","dates":{"published":"2024-06-04T20:59:56.390Z","modified":"2024-08-19T15:35:54.588Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.9,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5.9,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5.9,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00589,"percentile":0.472,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00589},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00589,"percentile":0.472}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00589,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","sco
