"The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0808 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2023-45142:
    OpenTelemetry-Go Contrib is a collection of third-party packages for OpenTelemetry-Go. A handler wrapper
    out of the box adds labels `http.user_agent` and `http.method` that have unbound cardinality. It leads to
    the server's potential memory exhaustion when many malicious requests are sent to it. HTTP header User-
    Agent or HTTP method for requests can be easily set by an attacker to be random and long. The library
    internally uses `httpconv.ServerRequest` that records every value for HTTP `method` and `User-Agent`. In
    order to be affected, a program has to use the `otelhttp.NewHandler` wrapper and not filter any unknown
    HTTP methods or User agents on the level of CDN, LB, previous middleware, etc. Version 0.44.0 fixed this
    issue when the values collected for attribute `http.request.method` were changed to be restricted to a set
    of well-known values and other high cardinality attributes were removed. As a workaround to stop being
    affected, `otelhttp.WithFilter()` can be used, but it requires manual careful configuration to not log
    certain requests entirely. For convenience and safe usage of this library, it should by default mark with
    the label `unknown` non-standard HTTP methods and User agents to show that such requests were made but do
    not increase cardinality. In case someone wants to stay with the current behavior, library API should
    allow to enable it.

    CVE-2023-25151:
    opentelemetry-go-contrib is a collection of extensions for OpenTelemetry-Go. The v0.38.0 release of
    `go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp` uses the `httpconv.ServerRequest` function
    to annotate metric measurements for the `http.server.request_content_length`,
    `http.server.response_content_length`, and `http.server.duration` instruments. The `ServerRequest`
    function sets the `http.target` attribute value to be the whole request URI (including the query
    string)[^1]. The metric instruments do not forget previous measurement attributes when `cumulative`
    temporality is used, this means the cardinality of the measurements allocated is directly correlated with
    the unique URIs handled. If the query string is constantly random, this will result in a constant increase
    in memory allocation that can be used in a denial-of-service attack. This issue has been addressed in
    version 0.39.0. Users are advised to upgrade. There are no known workarounds for this issue.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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