Summary

Debug mode leaks confidential data in Cilium

Details

Impact

When run in debug mode, Cilium may log sensitive information.

In particular, Cilium running in debug mode will log the values of headers if they match HTTP network policy rules. This issue affects Cilium versions:

1.7.* to 1.10.* inclusive
1.11.* before 1.11.16
1.12.* before 1.12.9
1.13.* before 1.13.2

In addition, Cilium 1.12.* before 1.12.9 and 1.13.* before 1.13.2., when running in debug mode, might log secrets used by the Cilium agent. This includes TLS private keys for Ingress and GatewayAPI resources, depending on the configuration of the affected cluster. Output of the confidential data would occur at Cilium agent restart, when the secrets are modified, and on creation of Ingress or GatewayAPI resources.

Patches

This vulnerability is fixed in Cilium releases 1.11.16, 1.12.9, and 1.13.2.

Workarounds

Disable debug mode.

Acknowledgements

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