Title

Cilium has possible unencrypted traffic between nodes when using WireGuard and L7 policies

Summary

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Starting in version 1.14.0 and prior to versions 1.14.8 and 1.15.2, In Cilium clusters with WireGuard enabled and traffic matching Layer 7 policies Wireguard-eligible traffic that is sent between a node's Envoy proxy and pods on other nodes is sent unencrypted and Wireguard-eligible traffic that is sent between a node's DNS proxy and pods on other nodes is sent unencrypted. This issue has been resolved in Cilium 1.14.8 and 1.15.2 in in native routing mode (`routingMode=native`) and in Cilium 1.14.4 in tunneling mode (`routingMode=tunnel`). Not that in tunneling mode, `encryption.wireguard.encapsulate` must be set to `true`. There is no known workaround for this issue.

GHSA-V6Q2-4QR3-5CW6

Vulnerability from github – Published: 2024-03-18 20:33 – Updated: 2024-03-19 18:31

Summary

Unencrypted traffic between nodes when using WireGuard and L7 policies

Details

Impact

In Cilium clusters with WireGuard enabled and traffic matching Layer 7 policies:

Traffic that should be WireGuard-encrypted is sent unencrypted between a node's Envoy proxy and pods on other nodes.
Traffic that should be WireGuard-encrypted is sent unencrypted between a node's DNS proxy and pods on other nodes.

Patches

This issue affects:

In native routing mode (routingMode=native):
Cilium v1.14 versions before v1.14.8
Cilium v1.15 versions before v1.15.2
In tunneling mode (routingMode=tunnel):
Cilium v1.14 versions before v1.14.4
Cilium v1.14.4 if encryption.wireguard.encapsulate is set to false (default).

This issue has been resolved in:

In native routing mode (routingMode=native):
Cilium v1.14.8
Cilium v1.15.2
In tunneling mode (routingMode=tunnel):
Cilium v1.14.4. NOTE encryption.wireguard.encapsulate must be set to true.

Workarounds

There is no workaround to this issue.
