CVE-2024-42487 (GCVE-0-2024-42487)

Vulnerability from cvelistv5 – Published: 2024-08-15 20:26 – Updated: 2024-08-15 20:46

Summary

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. In the 1.15 branch prior to 1.15.8 and the 1.16 branch prior to 1.16.1, Gateway API HTTPRoutes and GRPCRoutes do not follow the match precedence specified in the Gateway API specification. In particular, request headers are matched before request methods, when the specification describes that the request methods must be respected before headers are matched. This could result in unexpected behaviour with security This issue is fixed in Cilium v1.15.8 and v1.16.1. There is no workaround for this issue.

GHSA-QCM3-7879-XCWW

Vulnerability from github – Published: 2024-08-15 21:46 – Updated: 2024-09-30 19:48

Summary

Gateway API route matching order contradicts specification

Details

Impact

Gateway API HTTPRoutes and GRPCRoutes do not follow the match precedence specified in the Gateway API specification. In particular, request headers are matched before request methods, when the specification describes that the request methods must be respected before headers are matched (HTTPRouteRule, GRPCRouteRule).

If users create Gateway API resources that use both request headers and request methods in order to route to different destinations, then traffic may be delivered to the incorrect backend. If the backend does not have Network Policy restricting acceptable traffic to receive, then requests may access information that you did not intend for them to access.

Patches

This issue was fixed in https://github.com/cilium/cilium/pull/34109.

This issue affects: - Cilium v1.15 between v1.15.0 and v1.15.7 inclusive - Cilium v1.16.0

This issue is fixed in: - Cilium v1.15.8 - Cilium v1.16.1

Workarounds

There is no workaround for this issue.

Acknowledgements

The Cilium community has worked together with members of Cure53 and Isovalent to prepare these mitigations. Special thanks to @sayboras for remediating this issue.
