Unencrypted traffic between nodes when using IPsec and L7 policies

發布日:2024/3/18修改日:2026/2/4

描述

### Impact In Cilium clusters with IPsec enabled and traffic matching Layer 7 policies: - Traffic that should be IPsec-encrypted between a node's Envoy proxy and pods on other nodes is sent unencrypted - Traffic that should be IPsec-encrypted between a node's DNS proxy and pods on other nodes is sent unencrypted **Note:** For clusters running in native routing mode, IPsec encryption is not applied to connections which are selected by a L7 Egress Network Policy or a DNS Policy. This is a known limitation of Cilium's IPsec encryption which will continue to apply after upgrading to the latest Cilium versions described below. ### Patches This issue affects: - Cilium v1.15 before v1.15.2 - Cilium v1.14 before v1.14.8 - Cilium v1.13 before v1.13.13 - Cilium v1.4 to v1.12 inclusive This issue has been resolved in: - Cilium v1.15.2 - Cilium v1.14.8 - Cilium v1.13.13 ### Workarounds There is no workaround to this issue. ### Acknowledgements The Cilium community has worked together with members of Isovalent to prepare these mitigations. Special thanks to @jschwinger233, @julianwiedmann, @giorio94, and @jrajahalme for their work in triaging and resolving this issue. ### For more information If you have any questions or comments about this advisory, please reach out on [Slack](https://docs.cilium.io/en/latest/community/community/#slack).
