BIT-CILIUM-OPERATOR-2023-41332 Denial of service via Kubernetes annotations in specific Cilium configurations

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. In Cilium clusters where Cilium's Layer 7 proxy has been disabled, creating workloads with policy.cilium.io/proxy-visibility annotations in Cilium = v1.13 or io.cilium.proxy-visibility annotations in Cilium...

BIT-CILIUM-2023-41333 Bypass of namespace restrictions in CiliumNetworkPolicy

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. An attacker with the ability to create or modify CiliumNetworkPolicy objects in a particular namespace is able to affect traffic on an entire Cilium cluster, potentially bypassing policy enforcement in othe...

Inadequate Encryption Strength

Cilium is vulnerable to Inadequate Encryption Strength. The vulnerability is due to an ESP sequence number collision when multiple nodes are configured with the same key, leading to chosen plaintext, key recovery, and replay attacks by a man-in-the-middle attacker...
