https://notcve.org/view.php?id=CVE-2024-45810
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. There will be p... • https://github.com/envoyproxy/envoy/security/advisories/GHSA-qm74-x36m-555q • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

04 Jun 2024 — Envoy is a cloud-native, open source edge and service proxy. A crash was observed in `EnvoyQuicServerStream::OnInitialHeadersComplete()` with following call stack. It is a use-after-free caused by QUICHE continuing push request headers after `StopReading()` being called on the stream. As after `StopReading()`, the HCM's `ActiveStream` might have already be destroyed and any up calls from QUICHE could potentially cause use after free.

https://notcve.org/view.php?id=CVE-2024-23326
04 Jun 2024 — Envoy is a cloud-native, open source edge and service proxy. A theoretical request smuggling vulnerability exists through Envoy if a server can be tricked into adding an upgrade header into a response. Per RFC https://www.rfc-editor.org/rfc/rfc7230#section-6.7 a server sends 101 when switching protocols. Envoy incorrectly accepts a 200 response from a server when requesting a protocol upgrade, but 200 does not indicate protocol switch. This opens up the possibility of request smuggling through Envoy if the ... • https://github.com/envoyproxy/envoy/security/advisories/GHSA-vcf8-7238-v74c • CWE-391: Unchecked Error Condition CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

18 Apr 2024 — Envoy is a cloud-native, open source edge and service proxy. When an upstream TLS cluster is used with `auto_sni` enabled, a request containing a `host`/`:authority` header longer than 255 characters triggers an abnormal termination of Envoy process. Envoy does not gracefully handle an error when setting SNI for outbound TLS connection. The error can occur when Envoy attempts to use the `host`/`:authority` header value longer than 255 characters as SNI for outbound TLS connection.

CVSS: 8.2EPSS: 0%CPEs: 4EXPL: 1CVE-2023-35944 – Envoy vulnerable to incorrect handling of HTTP requests and responses with mixed case schemes
https://notcve.org/view.php?id=CVE-2023-35944
25 Jul 2023 — Envoy is an open source edge and service proxy designed for cloud-native applications. Envoy allows mixed-case schemes in HTTP/2, however, some internal scheme checks are case-sensitive. Prior to versions 1.27.0, 1.26.4, 1.25.9, 1.24.10, and 1.23.12, this can lead to the rejection of requests with mixed-case schemes such as `htTp` or `htTps`, or the bypassing of some requests such as `https` in unencrypted connections. With a fix in versions 1.27.0, 1.26.4, 1.25.9, 1.24.10, and 1.23.12, Envoy will now lower... • https://github.com/envoyproxy/envoy/security/advisories/GHSA-pvgm-7jpg-pw5g • CWE-20: Improper Input Validation CWE-178: Improper Handling of Case Sensitivity CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
