CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 0CVE-2024-53270 – HTTP/1: sending overload crashes when the request is reset beforehand in envoy
https://notcve.org/view.php?id=CVE-2024-53270
18 Dec 2024 — 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. • https://github.com/envoyproxy/envoy/pull/37743/commits/6cf8afda956ba67c9afad185b962325a5242ef02 • CWE-670: Always-Incorrect Control Flow Implementation •

18 Dec 2024 — Envoy is a cloud-native high-performance edge/middle/service proxy. When additional address are not ip addresses, then the Happy Eyeballs sorting algorithm will crash in data plane. This issue has been addressed in releases 1.32.2, 1.31.4, and 1.30.8. Users are advised to upgrade. Users unable to upgrade may disable Happy Eyeballs and/or change the IP configuration. • https://github.com/envoyproxy/envoy/pull/37743/commits/3f62168d86aceb90f743f63b50cc711710b1c401 • CWE-670: Always-Incorrect Control Flow Implementation •

https://notcve.org/view.php?id=CVE-2024-45806
19 Sep 2024 — Envoy is a cloud-native high-performance edge/middle/service proxy. A security vulnerability in Envoy allows external clients to manipulate Envoy headers, potentially leading to unauthorized access or other malicious actions within the mesh. This issue arises due to Envoy's default configuration of internal trust boundaries, which considers all RFC1918 private address ranges as internal. The default behavior for handling internal addresses in Envoy has been changed. Previously, RFC1918 IP addresses were aut... • https://github.com/envoyproxy/envoy/security/advisories/GHSA-ffhv-fvxq-r6mf • CWE-639: Authorization Bypass Through User-Controlled Key •

19 Sep 2024 — Envoy is a cloud-native high-performance edge/middle/service proxy. A vulnerability has been identified in Envoy that allows malicious attackers to inject unexpected content into access logs. This is achieved by exploiting the lack of validation for the `REQUESTED_SERVER_NAME` field for access loggers. This issue has been addressed in versions 1.31.2, 1.30.6, 1.29.9, and 1.28.7.

19 Sep 2024 — Envoy is a cloud-native high-performance edge/middle/service proxy. Jwt filter will lead to an Envoy crash when clear route cache with remote JWKs. In the following case: 1. remote JWKs are used, which requires async header processing; 2. clear_route_cache is enabled on the provider; 3. header operations are enabled in JWT filter, e.g. header to claims feature; 4. the routing table is configured in a way that the JWT header operations modify requests to not match any route.

19 Sep 2024 — Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy will crash when the http async client is handling `sendLocalReply` under some circumstance, e.g., websocket upgrade, and requests mirroring. The http async client will crash during the `sendLocalReply()` in http async client, one reason is http async client is duplicating the status code, another one is the destroy of router is called at the destructor of the async stream, while the stream is deferred deleted at first.

01 Jul 2024 — Envoy is a cloud-native, open source edge and service proxy. Prior to versions 1.30.4, 1.29.7, 1.28.5, and 1.27.7. Envoy references already freed memory when route hash policy is configured with cookie attributes. Note that this vulnerability has been fixed in the open as the effect would be immediately apparent if it was configured. Memory allocated for holding attribute values is freed after configuration was parsed. • https://github.com/envoyproxy/envoy/commit/02a06681fbe0e039b1c7a9215257a7537eddb518 • CWE-416: Use After Free •
