{"cve":"CVE-2024-28860","nvd":{"published":"2024-03-27T19:15:48.827","modified":"2026-06-17T07:21:54.227","status":"Analyzed","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":6.8},"cwes":["CWE-326"],"references":["https://docs.cilium.io/en/stable/security/network/encryption-ipsec","https://github.com/cilium/cilium/commit/311fbce5280491cddceab178d83b06fa23688c72","https://github.com/cilium/cilium/commit/a1742b478306fa256cd27df1039dfae0537b4149","https://github.com/cilium/cilium/commit/a652c123331852cca90c74202f993d4170fd37fa","https://github.com/cilium/cilium/security/advisories/GHSA-pwqm-x5x6-5586"],"products":["cilium:cilium"],"source":"nvd","synced_at":"2026-10-19T21:47:51.568503435+00:00"},"epss":{"cve":"CVE-2024-28860","score":0.00172,"percentile":0.06584,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-pwqm-x5x6-5586","url":"https://osv.dev/vulnerability/GHSA-pwqm-x5x6-5586","summary":"Cilium has insecure IPsec transport encryption","modified":"2026-09-10T03:50:10.760592503Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.4.0 <1.13.14"],"fixed":["1.13.14"]},{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.14.0 <1.14.9"],"fixed":["1.14.9"]},{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":[">=1.15.0 <1.15.3"],"fixed":["1.15.3"]}]},{"id":"GO-2024-2666","url":"https://osv.dev/vulnerability/GO-2024-2666","summary":"Insecure IPsec transparent encryption in github.com/cilium/cilium","modified":"2026-02-04T03:27:31.877802Z","packages":[{"ecosystem":"Go","name":"github.com/cilium/cilium","purl":"pkg:golang/github.com/cilium/cilium","ranges":["<1.13.14",">=1.14.0 <1.14.9",">=1.15.0 <1.15.3"],"fixed":["1.13.14","1.14.9","1.15.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
