CVE-2022-0811

EIP tracks 1 public exploit for CVE-2022-0811. PoCs published by spiarh.

AI-analyzed exploit summary This repository contains a Kubernetes admission webhook designed to mitigate CVE-2022-0811 by blocking pod creation if sysctl values contain '+' or '=' characters, which could be exploited for container escapes. The PoC includes a Go-based webhook server and test cases to validate the functionality.

A flaw was found in CRI-O in the way it set kernel options for a pod. This issue allows anyone with rights to deploy a pod on a Kubernetes cluster that uses the CRI-O runtime to achieve a container escape and arbitrary code execution as root on the cluster node, where the malicious pod was deployed.
