CrowdStrike discloses container escape vulnerability affecting CRI-O for Kubernetes. Here’s how Tenable.cs can help you detect vulnerable pods.

Cr8escape: How Tenable Can Help (CVE-2022-0811)

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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of the CRI-O package installed on the remote host is 1.19.x prior to 1.19.6, 1.20.x prior to 1.20.7, 1.21.x prior to 1.21.6, 1.22.x prior to 1.22.3, or 1.23.x prior to 1.23.2. It is, therefore, affected by an arbitrary code execution vulnerability via abusing the 'kernel.core_pattern' kernel parameter.
