CVE-2019-11248 Scanner

Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It is widely used to manage complex distributed systems and microservices-based applications in enterprise environments. The platform provides a uniform way to deploy, manage, and scale applications across various environments, such as on-premises or public clouds. Kubernetes has become an industry standard for container orchestration, empowering businesses to run complex workloads at scale with ease.

The CVE-2019-11248 vulnerability is a security flaw in Kubernetes versions prior to 1.15.0, 1.14.4, 1.13.8, and 1.12.10. The debugging endpoint /debug/pprof is exposed over the unauthenticated Kubelet healthz port, potentially leaking sensitive information about the internal Kubelet memory addresses and configuration. This can lead to a limited denial of service attack or other security issues.

When exploited, this vulnerability can enable attackers to gain access to sensitive information, such as memory addresses and configurations, compromising the security of the entire Kubernetes system. The potential access to sensitive data, in turn, can lead to data breaches or other security incidents that might result in significant financial losses or damage to reputation for enterprises utilizing Kubernetes.
