The default_validator.cc implementation used to implement the default certificate validation routines has a \"type confusion\" bug when processing subjectAltNames. This processing allows, for example, an rfc822Name or uniformResourceIndicator to be authenticated as a domain name. This confusion allows for the bypassing of nameConstraints, as processed by the underlying OpenSSL/BoringSSL implementation, exposing the possibility of impersonation of arbitrary servers. As a result Envoy will trust upstream certificates that should not be trusted.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/37911"}, {"timestamp": "2022-02-24T00:00:00Z", "date_only": true, "value": "2022-02-24", "kind": "other", "label": "Submit Time", "source": "cnvd \u00b7 CNVD-2022-16290", "record": "CNVD-2022-16290", "field": "submitTime"}, {"timestamp": "2022-03-03T00:00:00Z", "date_only": true, "value": "2022-03-03", "kind": "other", "label": "Open Time", "source": "cnvd \u00b7 CNVD-2022-16290", "record": "CNVD-2022-16290", "field": "openTime"}, {"timestamp": "2023-07-24T13:50:00Z", "date_only": false, "value": "2023-07-24T13:50Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2022-21656", "record": "GSD-2022-21656", "field": "namespaces.nvd.nist.gov.lastModifiedDate"}, {"timestamp": "2023-12-13T01:19:14.569Z", "date_only": false, "value": "2023-12-13T01:19:14.569340Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2022-21656", "record": "GSD-2022-21656", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-03-06T10:56:05.460Z", "date_only": false, "value": "2024-03-06T10:56:05.460Z", "kind": "milestone", "label": "Published", "source": "bitnami_vulndb \u00b7 BIT-ENVOY-2022-21656", "record": "BIT-ENVOY-2022-21656", "field": "published"}, {"timestamp": "2024-08-03T02:46:39.567Z", "date_only": false, "value": "2024-08-03T02:46:39.567Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2022-21656", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2025-04-23T15:55:47.477Z", "date_only": false, "value": "2025-04-23T15:55:47.477332Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2022-21656", "field": "containers.adp.1.metrics.0.other.content.timestamp"}, {"timestamp": "2025-04-23T15:55:47.477Z", "date_only": false, "value": "2025-04-23T15:55:47.477332Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2022-21656", "record": "FKIE_CVE-2022-21656", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2025-04-23T19:01:38.563Z", "date_only": false, "value": "2025-04-23T19:01:38.563Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2022-21656", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2025-04-23T19:01:38.563Z", "date_only": false, "value": "2025-04-23T19:01:38.563Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2022-21656", "field": "containers.adp.1.providerMetadata.dateUpdated"}, {"timestamp": "2026-06-17T04:26:41.863Z", "date_only": false, "value": "2026-06-17T04:26:41.863", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2022-21656", "record": "FKIE_CVE-2022-21656", "field": "lastModified"}, {"timestamp": "2026-09-10T15:46:03.895Z", "date_only": false, "value": "2026-09-10T15:46:03.895Z", "kind": "other", "label": "Updated", "source": "bitnami_vulndb \u00b7 BIT-ENVOY-2022-21656", "record": "BIT-ENVOY-2022-21656", "field": "modified"}]}
