自己報告されたバージョン番号によると、リモートホストで実行されている Grafana Enterprise のバージョンは、9.4.17より前の 9.4.x、9.5.13 より前の 9.5.x、10.0.9 より前の 10.0.x、または 10.1.5 より前の 10.1.x です。したがって、制限バイパスの脆弱性の影響を受けます。Grafana Enterprise では、リクエストセキュリティ機能により、管理者はインスタンスが特定のホストを呼び出さないように Grafana を構成できます。ただし、この制限によってリクエストアドレスの文字に使用されている punycode エンコーディングをバイパスする可能性があります。
 Nessus はこれらの問題をテストしておらず、代わりにアプリケーションが自己報告するバージョン番号にのみ依存していることに注意してください。

根據所回報的版本號碼，遠端主機上執行的 Grafana Enterprise 版本是早於 9.4.17 的 9.4.x、早於 9.5.13 的 9.5.x、早於 10.0.9 的 10.0.x，或是早於 10.1.5 的 10.1.x。因此，此版本受到限制繞過弱點影響。在 Grafana Enterprise 中，要求安全性為拒絕清單，可讓管理員設定 Grafana，使執行個體不會呼叫特定主機。不過，該限制可繞過要求位址中字元所用的 punycode 編碼。
 請注意，Nessus 並未測試這些問題，而是僅依據應用程式自我報告的版本號碼作出判斷。

根据其自我报告的版本号，远程主机上运行的 Grafana Enterprise 版本为低于 9.4.17 的 9.4.x、低于 9.5.13 的 9.5.x、低于 10.0.9 的 10.0.x 或低于 10.1.5 的 10.1.x。因此，它受到限制绕过漏洞的影响。在 Grafana Enterprise 中，请求安全是一个拒绝列表，允许管理员以某种方式配置 Grafana，以便实例不会调用特定主机。但是，可以通过对请求地址中的字符进行 punycode 编码来绕过该限制。
 请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

According to its self-reported version number, the version of Grafana Enterprise running on the remote host is a version 9.4.x prior to 9.4.17, 9.5.x prior to 9.5.13, 10.0.x prior to 10.0.9 or 10.1.x prior to 10.1.5. It is, therefore, affected by a restriction bypass vulnerability.  In Grafana Enterprise, Request security is a deny list that allows admins to configure Grafana in a way so that the instance does not call specific hosts. However, the restriction can be bypassed used punycode encoding of the characters in the request address.
 Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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-2024:0907 advisory.

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

    CVE-2023-49568:
    Grafana is an open-source platform for monitoring and observability. In Grafana Enterprise, Request     security is a deny list that allows admins to configure Grafana in a way so that the instance doesnt     call specific hosts. However, the restriction can be bypassed used punycode encoding of the characters in     the request address.

    CVE-2023-6152:
    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:
    A path traversal vulnerability was discovered in go-git versions prior to v5.11. This vulnerability allows     an attacker to create and amend files across the filesystem. In the worse case scenario, remote code     execution could be achieved. Applications are only affected if they are using the ChrootOS     https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#ChrootOS , which is the default when using Plain     versions of Open and Clone funcs (e.g. PlainClone). Applications using BoundOS     https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#BoundOS  or in-memory filesystems are not affected     by this issue. This is a go-git implementation issue and does not affect the upstream git cli.

    CVE-2024-1442:
    A user with the permissions to create a data source can use Grafana API to create a data source with UID     set to *. Doing this will grant the user access to read, query, edit and delete all data sources within     the organization.

    CVE-2023-4399:
    A denial of service (DoS) vulnerability was discovered in go-git versions prior to v5.11. This     vulnerability allows an attacker to perform denial of service attacks by providing specially crafted     responses from a Git server which triggers resource exhaustion in go-git clients. Applications using only     the in-memory filesystem supported by go-git are not affected by this vulnerability. This is a go-git     implementation issue and does not affect the upstream git cli.

    CVE-2024-1313:
    It is possible for a user in a different organization from the owner of a snapshot to bypass authorization     and delete a snapshot by issuing a DELETE request to /api/snapshots/<key> using its view key. This     functionality is intended to only be available to individuals with the permission to write/edit to the     snapshot in question, but due to a bug in the authorization logic, deletion requests issued by an     unprivileged user in a different organization than the snapshot owner are treated as authorized. Grafana     Labs would like to thank Ravid Mazon and Jay Chen of Palo Alto Research for discovering and disclosing     this vulnerability. This issue affects Grafana: from 9.5.0 before 9.5.18, from 10.0.0 before 10.0.13, from     10.1.0 before 10.1.9, from 10.2.0 before 10.2.6, from 10.3.0 before 10.3.5.

    CVE-2023-49569:
    A user changing their email after signing up and verifying it can change it without verification in     profile settings. The configuration option verify_email_enabled will only validate email only on sign     up.

    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.

    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.

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 number.
