Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Prior to versions 1.13.13, 1.14.8, and 1.15.2, in Cilium clusters with IPsec enabled and traffic matching Layer 7 policies, IPsec-eligible traffic between a node's Envoy proxy and pods on other nodes is sent unencrypted and IPsec-eligible traffic between a node's DNS proxy and pods on other nodes is sent unencrypted. This issue has been resolved in Cilium 1.15.2, 1.14.8, and 1.13.13. There is no known workaround for this issue.

CVE-2024-28249 Unencrypted traffic between nodes with IPsec in github.com/cilium/cilium
Unencrypted traffic between nodes with IPsec in github.com/cilium/cilium
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, and traffic that should be IPsec-encrypted between a node's DNS proxy and pods on other nodes is sent unencrypted.

CVE-2024-28249 [MEDIUM] CWE-311 Unencrypted traffic between nodes when using IPsec and L7 policies
Unencrypted traffic between nodes when using IPsec and L7 policies
### 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
- Ci
