New Vulnerability in CRI-O Engine Lets Attackers Escape Kubernetes Containers

March 17, 2022Ravie Lakshmanan
A newly disclosed security vulnerability in the Kubernetes container engine CRI-O called  cr8escape  could be exploited by an attacker to break out of containers and obtain root access to the host. "Invocation of CVE-2022-0811 can allow an attacker to perform a variety of actions on objectives, including execution of malware, exfiltration of data, and lateral movement across pods," CrowdStrike researchers John Walker and Manoj Ahuje  said  in an analysis published this week. A lightweight alternative to Docker,  CRI-O  is a  container runtime  implementation of the Kubernetes Container Runtime Interface (CRI) that's used to pull container images from registries and launch an Open Container Initiative ( OCI )-compatible runtime such as runC to spawn and run container processes. The vulnerability is rated 8.8 on the CVSS vulnerability scoring system and affects CRI-O versions 1.19 and later. Following responsible disclosure, patches have been released to address the fl
