{"id":"CVE-2024-53270","state":"PUBLISHED","title":"HTTP/1: sending overload crashes when the request is reset beforehand in envoy","description":"Envoy is a cloud-native high-performance edge/middle/service proxy. In affected versions `sendOverloadError` is going to assume the active request exists when `envoy.load_shed_points.http1_server_abort_dispatch` is configured. If `active_request` is nullptr, only onMessageBeginImpl() is called. However, the `onMessageBeginImpl` will directly return ok status if the stream is already reset leading to the nullptr reference. The downstream reset can actually happen during the H/2 upstream reset. As a result envoy may crash. This issue has been addressed in releases 1.32.3, 1.31.5, 1.30.9, and 1.29.12. Users are advised to upgrade. Users unable to upgrade may disable `http1_server_abort_dispatch` load shed point and/or use a high threshold.","publishedAt":"2024-12-18T19:12:18.775Z","updatedAt":"2024-12-18T21:35:24.476Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["envoyproxy envoy"],"affected":[{"vendor":"envoyproxy","product":"envoy","versions":[{"version":">= 1.32.0, < 1.32.3","status":"affected"},{"version":">= 1.31.0, < 1.31.5","status":"affected"},{"version":">= 1.30.0, < 1.30.9","status":"affected"},{"version":"< 1.29.12","status":"affected"}]}],"references":["https://github.com/envoyproxy/envoy/security/advisories/GHSA-q9qv-8j52-77p3","https://github.com/envoyproxy/envoy/pull/37743/commits/6cf8afda956ba67c9afad185b962325a5242ef02"],"weaknesses":["CWE-670"],"ingestedAt":"2026-10-29T20:08:04.920Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/53xxx/CVE-2024-53270.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2024-53270","state":"PUBLISHED","datePublished":"2024-12-18T19:12:18.775Z","dateUpdated":"2024-12-18T21:35:24.476Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2024-11-19T20:08:14.482Z"},"containers":{"cna":{"title":"HTTP/1: sending overload crashes when the request is reset beforehand in envoy","descriptions":[{"lang":"en","value":"Envoy is a cloud-native high-performance edge/middle/service proxy.
