Envoy has carved out a critical role in cloud-native computing, becoming increasingly prevalent as the default ingress controller for Kubernetes. This high-performance proxy, developed by Lyft and now part of the Cloud Native Computing Foundation’s arsenal, is integral for companies scaling up their Kubernetes deployments. Envoy ensures efficient load balancing, security, and operational agility by managing external access to services within Kubernetes clusters,. Big names in tech, such as Google, IBM, and Pivotal, rely on Envoy for its robust feature set in their Kubernetes environments. Its ability to simplify complex service-to-service communication is invaluable in dynamic service environments and highlights its capabilities as an edge and middle proxy that optimizes API management across various platforms. Employing Envoy as an ingress controller in Kubernetes offers substantial benefits by centralizing the entry points into the environment and providing fine-grained control over traffic management and security. However, the spotlight on Envoy also brings to light significant vulnerabilities, as evidenced by the recent discovery of CVE-2024-45806, CVE-2024-45809, and CVE-2024-45810. These vulnerabilities pose risks such as unauthorized access, bypassing security controls, and potential denial of service—issues that can severely impact any system's integrity and availability. The versions affected by these vulnerabilities are the following: 1.29 (CVE-2024-45809) 1.32.0…Read More
