The version of containerd installed on the remote host is prior to 1.7.11-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2ECS-2024-035 advisory.

  - A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive     server resource consumption. While the total number of requests is bounded by the     http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create     a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound     the number of simultaneously executing handler goroutines to the stream concurrency limit     (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client     has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows     too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2     for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per     HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see the     Server.MaxConcurrentStreams setting and the ConfigureServer function. (CVE-2023-39325)

  - A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response     body to read many more bytes from the network than are in the body. A malicious HTTP client can further     exploit this to cause a server to automatically read a large amount of data (up to about 1GiB) when a     handler fails to read the entire body of a request. Chunk extensions are a little-used HTTP feature which     permit including additional metadata in a request or response body sent using the chunked encoding. The     net/http chunked encoding reader discards this metadata. A sender can exploit this by inserting a large     metadata segment with each byte transferred. The chunk reader now produces an error if the ratio of real     body to encoded bytes grows too small. (CVE-2023-39326)

  - Text nodes not in the HTML namespace are incorrectly literally rendered, causing text which should be     escaped to not be. This could lead to an XSS attack. (CVE-2023-3978)

  - OpenTelemetry-Go Contrib is a collection of third-party packages for OpenTelemetry-Go. Prior to version     0.46.0, the grpc Unary Server Interceptor out of the box adds labels `net.peer.sock.addr` and     `net.peer.sock.port` that have unbound cardinality. It leads to the server's potential memory exhaustion     when many malicious requests are sent. An attacker can easily flood the peer address and port for     requests. Version 0.46.0 contains a fix for this issue. As a workaround to stop being affected, a view     removing the attributes can be used. The other possibility is to disable grpc metrics instrumentation by     passing `otelgrpc.WithMeterProvider` option with `noop.NewMeterProvider`. (CVE-2023-47108)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
