Unencrypted traffic between nodes when using IPsec and L7 policies
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
In Cilium clusters with IPsec enabled and traffic matching Layer 7 policies:
Potential 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.
Evidence: public source recordsAffected products
| Affected package, product or range | Fix status |
|---|---|
| Consult the referenced vendor advisory for affected versions. | Consult source advisory |
Matching a version is only one part of assessing exposure. QFinch has not assessed your environment on this public page.
Remediation
Apply the vendor-supported fixed release or mitigation, then verify the affected component is no longer reachable.
- Confirm the affected product and reachable code path exist in your environment.
- Apply the vendor-supported patch or mitigation from the primary advisory.
- Rescan the exact deployed revision and retain verification evidence.
