## Overview

### Impact

`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. 

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.

### Patches

This issue is patched in `cilium-cli` 0.13.2

All previous versions of `cilium-cli` are affected. Users who have set up cluster meshes using the Cilium Helm chart are not affected.

### Workarounds

Use Cilium's [Helm charts](https://artifacthub.io/packages/helm/cilium/cilium) to create your cluster instead.

### Acknowledgements

The Cilium community has worked together with members of Isovalent to prepare these mitigations. Special thanks to Marco Iorio for investigating and fixing the issue.
