{"id":"BIT-envoy-2022-21655","summary":"Incorrect handling of internal redirects results in crash in Envoy","details":"Envoy is an open source edge and service proxy, designed for cloud-native applications. The envoy common router will segfault if an internal redirect selects a route configured with direct response or redirect actions. This will result in a denial of service. As a workaround turn off internal redirects if direct response entries are configured on the same listener.","aliases":["CVE-2022-21655","GHSA-7r5p-7fmh-jxpg"],"modified":"2026-09-08T08:47:33.463986783Z","published":"2024-03-06T10:56:14.571Z","database_specific":{"cpes":["cpe:2.3:a:envoyproxy:envoy:*:*:*:*:*:*:*:*"],"severity":"High"},"references":[{"type":"ADVISORY","url":"https://github.com/envoyproxy/envoy/commit/177d608155ba8b11598b9bbf8240e90d8c350682"},{"type":"ADVISORY","url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-7r5p-7fmh-jxpg"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-21655"}],"affected":[{"package":{"name":"envoy","ecosystem":"Bitnami","purl":"pkg:bitnami/envoy"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.18.6"},{"introduced":"1.19.0"},{"fixed":"1.19.3"},{"introduced":"1.20.0"},{"fixed":"1.20.2"},{"introduced":"1.21.0"},{"fixed":"1.21.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/envoy/BIT-envoy-2022-21655.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"}
