Detecting the Kubernetes API server DoS vulnerability (CVE-2019-1002100).

A recently identified Kubernetes vulnerability, CVE-2019-1002100, affects the kube-apiserver, where authorized users with write permissions might conduct a denial-of-service attack, causing the API server to be overloaded. This medium-severity issue, with a CVSS score of 6.5, can be resolved by upgrading to specific versions of the kube-apiserver or by removing 'patch' permissions from untrusted users. Sysdig provides a cloud-native intelligence platform to mitigate such vulnerabilities by monitoring and alerting for abnormal traffic patterns that could indicate a potential DoS attack. Their tools allow users to detect unusual inbound and outbound traffic, understand the context of the attack, and inspect user commands post-incident. Despite being labeled medium severity, the vulnerability poses significant risks, especially if a malicious user compromises a container with patch privileges, necessitating diligent monitoring and security practices.
