CVE-2024-28860 (GCVE-0-2024-28860)

Vulnerability from cvelistv5 – Published: 2024-03-27 18:34 – Updated: 2025-04-10 18:25

Title

Insecure IPsec transport encryption in Cilium

Summary

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Users of IPsec transparent encryption in Cilium may be vulnerable to cryptographic attacks that render the transparent encryption ineffective. In particular, Cilium is vulnerable to chosen plaintext, key recovery, replay attacks by a man-in-the-middle attacker. These attacks are possible due to an ESP sequence number collision when multiple nodes are configured with the same key. Fixed versions of Cilium use unique keys for each IPsec tunnel established between nodes, resolving all of the above attacks. This vulnerability is fixed in 1.13.13, 1.14.9, and 1.15.3.

Users of IPsec transparent encryption in Cilium may be vulnerable to cryptographic attacks that render the transparent encryption ineffective. In particular, Cilium is vulnerable to chosen plaintext, key recovery, replay attacks by a man-in-the-middle attacker. These attacks are possible due to an ESP sequence number collision when multiple nodes are configured with the same key. Fixed versions of Cilium use unique keys for each IPsec tunnel established between nodes, resolving all of the above attacks. This vulnerability is fixed in 1.13.13, 1.14.9, and 1.15.3."

En particular, Cilium es vulnerable a texto plano elegido, recuperaci\u00f3n de claves y ataques de repetici\u00f3n por parte de un atacante intermediario. Estos ataques son posibles debido a una colisi\u00f3n del n\u00famero de secuencia ESP cuando se configuran varios nodos con la misma clave.

GHSA-PWQM-X5X6-5586

Vulnerability from github – Published: 2024-03-28 17:27 – Updated: 2024-04-16 18:51

Summary

Cilium has insecure IPsec transport encryption

Details

Impact

Users of IPsec transparent encryption in Cilium may be vulnerable to cryptographic attacks that render the transparent encryption ineffective.

In particular, Cilium is vulnerable to the following attacks by a man-in-the-middle attacker:

Chosen plaintext attacks
Key recovery attacks
Replay attacks

These attacks are possible due to an ESP sequence number collision when multiple nodes are configured with the same key. Fixed versions of Cilium use unique keys for each IPsec tunnel established between nodes, resolving all of the above attacks.

Important: After upgrading, users must perform a key rotation using the instructions here to ensure that they are no longer vulnerable to this issue. Please note that the key rotation instructions have recently been updated, and users must use the new instructions to properly establish secure IPsec tunnels. To validate that the new instructions have been followed properly, ensure that the IPsec Kubernetes secret contains a "+" sign.

Patches

All prior versions of Cilium that support IPsec transparent encryption (Cilium 1.4 onwards) are affected by this issue.

Patched versions:

Cilium 1.15.3
Cilium 1.14.9
Cilium 1.13.14

Workarounds

There is no workaround to this issue. IPsec transparent encryption users are strongly encouraged to upgrade.

Acknowledgements

The Cilium community has worked together with members of Cure53 and Isovalent to prepare these mitigations. Special thanks to @NikAleksandrov and @pchaigno for their work on remediating the issue. Thanks to Marsh Ray, Senior Software Developer at Microsoft, for input and guidance on the fix.

For more information

If you have any questions or comments about this advisory, please reach out on Slack.

As usual, if you think you found a related vulnerability, we strongly encourage you to report security vulnerabilities to our private security mailing list: security@cilium.io - first, before disclosing them in any public forums. This is a private mailing list where only members of the Cilium internal security team are subscribed to, and is treated as top priority.

Severity

8.0 (High)

Users of IPsec transparent encryption in Cilium may be vulnerable to cryptographic attacks that render the transparent encryption ineffective. In particular, Cilium is vulnerable to chosen plaintext, key recovery, replay attacks by a man-in-the-middle attacker. These attacks are possible due to an ESP sequence number collision when multiple nodes are configured with the same key. Fixed versions of Cilium use unique keys for each IPsec tunnel established between nodes, resolving all of the above attacks. This vulnerability is fixed in 1.13.13, 1.14.9, and 1.15.3."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
