Details
Summary
CVE-2023-41333 is a vulnerability in Cilium, a networking, observability, and security solution with an eBPF-based dataplane. It allows an attacker with API server access to create or modify CiliumNetworkPolicy objects in a specific namespace, enabling them to impact traffic across the entire Cilium cluster and potentially bypass policy enforcement in other namespaces. This can result in the attacker being able to allow or deny all traffic on the cluster. The issue has been resolved in Cilium versions 1.14.2, 1.13.7, and 1.12.14. As a temporary workaround, organizations can utilize an admission webhook to prevent the use of certain endpointSelectors that exploit this vulnerability in CiliumNetworkPolicies. The vulnerability has a base severity rating of MEDIUM and poses a potential danger to organizations that use Cilium for networking and security purposes on their clusters.
