Design/Logic Flaw

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 wit...

CVE-2023-35944

CVE-2023-35944 affects Envoy. The issue arises from case-sensitive internal HTTP/2 scheme checks, allowing mixed-case schemes (e.g., htTp, htTps) to be rejected or to bypass certain requests over unencrypted connections. The vulnerability exists prior to fixed releases and is mitigated by a patch...

CVE-2023-35945

CVE-2023-35945 affects Envoy’s HTTP/2 codec. The root cause is in nghttp2 cleanup: after RST_STREAM and subsequent GOAWAY, cleanup of pending requests skips deallocation, leaking header/bookkeeping structures and causing memory exhaustion (DoS). Patched in these versions: 1.26.3, 1.25.8, 1.24.9, ...
