CVE-2023-28114— Cilium 安全漏洞

`cilium-cli` disables etcd authorization for clustermesh clusters

`cilium-cli` is the command line interface to install, manage, and troubleshoot Kubernetes clusters running Cilium. Prior to version 0.13.2,`cilium-cli`, when used to configure cluster mesh functionality, can remove the enforcement of user permissions on the `etcd` store used to mirror local cluster information to remote clusters. Users who have set up cluster meshes using the Cilium Helm chart are not affected by this issue. Due to an incorrect mount point specification, the settings specified by the `initContainer` that configures `etcd` users and their permissions are overwritten when using `cilium-cli` to configure a cluster mesh. An attacker who has already gained access to a valid key and certificate for an `etcd` cluster compromised in this manner could then modify state in that `etcd` cluster. This issue is patched in `cilium-cli` 0.13.2. As a workaround, one may use Cilium's Helm charts to create their cluster.

不充分权限或特权的处理不恰当

Cilium 安全漏洞

Cilium是一个开源软件。用于提供和透明地保护应用程序工作负载（如应用程序容器或进程）之间的网络连接和负载平衡。 Cilium cilium-cli 0.13.2之前版本存在安全漏洞，该漏洞源于使用了不正确的挂载点规范，在使用cilium-cli配置集群网格时，配置etcd用户及其权限的initContainer指定的设置将被覆盖。
