8.0 · HIGH

Cilium is a networking, observability, and security solution with an eBPF-based dataplane.

Published Mar 27, 2024CWE-326EPSS 0.17%

Overview

CVE-2024-28860 is a high-severity vulnerability. It was published on March 27, 2024 and has a CVSS 3.1 base score of 8.0 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.0, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
