The version of cmake / nghttp2 / nodejs / nodejs18 installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-35945 advisory.

  - Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy's HTTP/2 codec May leak a header     map and bookkeeping structures upon receiving `RST_STREAM` immediately followed by the `GOAWAY` frames     from an upstream server. In nghttp2, cleanup of pending requests due to receipt of the `GOAWAY` frame     skips de-allocation of the bookkeeping structure and pending compressed header. The error return [code     path] is taken if connection is already marked for not sending more requests due to `GOAWAY` frame. The     clean-up code is right after the return statement, causing memory leak. Denial of service through memory     exhaustion. This vulnerability was patched in versions(s) 1.26.3, 1.25.8, 1.24.9, 1.23.11.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-300 advisory.

    Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to versions     1.27.0, 1.26.4, 1.25.9, 1.24.10, and 1.23.12, a malicious client is able to construct credentials with     permanent validity in some specific scenarios. This is caused by the some rare scenarios in which HMAC     payload can be always valid in OAuth2 filter's check. Versions 1.27.0, 1.26.4, 1.25.9, 1.24.10, and     1.23.12 have a fix for this issue. As a workaround, avoid wildcards/prefix domain wildcards in the host's     domain configuration. (CVE-2023-35941)

    Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to versions     1.27.0, 1.26.4, 1.25.9, 1.24.10, and 1.23.12, gRPC access loggers using listener's global scope can cause     a `use-after-free` crash when the listener is drained. Versions 1.27.0, 1.26.4, 1.25.9, 1.24.10, and     1.23.12 have a fix for this issue. As a workaround, disable gRPC access log or stop listener update.

    Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to versions     1.27.0, 1.26.4, 1.25.9, 1.24.10, and 1.23.12, the CORS filter will segfault and crash Envoy when the     `origin` header is removed and deleted between `decodeHeaders`and `encodeHeaders`. Versions 1.27.0,     1.26.4, 1.25.9, 1.24.10, and 1.23.12 have a fix for this issue. As a workaround, do not remove the     `origin` header in the Envoy configuration. (CVE-2023-35943)

    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 lowercase scheme     values by default, and change the internal scheme checks that were case-sensitive to be case-insensitive.
    There are no known workarounds for this issue. (CVE-2023-35944)

    (CVE-2023-35945)

  - nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior     to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is     reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2     v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream.
    There is no workaround for this vulnerability. (CVE-2024-28182)
