{"id":"BIT-envoy-2024-53270","summary":"HTTP/1: sending overload crashes when the request is reset beforehand in envoy","details":"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.","aliases":["CVE-2024-53270","GHSA-q9qv-8j52-77p3"],"modified":"2026-09-08T08:47:33.635181973Z","published":"2024-12-20T07:08:32.803Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:envoyproxy:envoy:*:*:*:*:*:*:*:*"]},"references":[{"type":"FIX","url":"https://github.com/envoyproxy/envoy/pull/37743/commits/6cf8afda956ba67c9afad185b962325a5242ef02"},{"type":"ADVISORY","url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-q9qv-8j52-77p3"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-53270"}],"affected":[{"package":{"name":"envoy","ecosystem":"Bitnami","purl":"pkg:bitnami/envoy"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.29.12"},{"introduced":"1.30.0"},{"fixed":"1.30.9"},{"introduced":"1.31.0"},{"fixed":"1.31.5"},{"introduced":"1.32.0"},{"fixed":"1.32.3"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/envoy/BIT-envoy-2024-53270.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.9.0"}
