A security issue was discovered in Kubernetes where a user that can create pods on Windows nodes may be able to escalate to admin privileges on those nodes. Kubernetes clusters are only affected if they include Windows nodes.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A security issue was discovered in Kubernetes where a user that can create pods on Windows nodes may be     able to escalate to admin privileges on those nodes. Kubernetes clusters are only affected if they include     Windows nodes. (CVE-2023-3676)

Note that Nessus relies on the presence of the package as reported by the vendor.

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-2024:0867 advisory.

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

    CVE-2023-3676:
    A security issue was discovered in Kubernetes where a user that can create pods and persistent volumes on     Windows nodes may be able to escalate to admin privileges on those nodes. Kubernetes clusters are only     affected if they are using an in-tree storage plugin for Windows nodes.

    CVE-2023-5528:
    A security issue was discovered in Kubernetes where a user      that can create pods on Windows nodes may be able to escalate to admin     privileges on those nodes. Kubernetes clusters are only affected if they      include Windows nodes.


    CVE-2022-3162:
    Users authorized to list or watch one type of namespaced custom resource cluster-wide can read custom     resources of a different type in the same API group without authorization. Clusters are impacted by this     vulnerability if all of the following are true: 1. There are 2+ CustomResourceDefinitions sharing the same     API group 2. Users have cluster-wide list or watch authorization on one of those custom resources. 3. The     same users are not authorized to read another custom resource in the same API group.
