CVE-2024-10220
Description
A flaw was found in the Kubelet component from the Kubernetes package. This flaw allows an attacker to create a pod and an associated gitRepo volume to execute arbitrary commands outside the container, bypassing the intended isolation between the container and the host.
Statement
This vulnerability is classified as important severity due to its potential to allow arbitrary command execution beyond the container boundary, which can lead to severe security breaches. By leveraging the hooks folder in the target repository associated with the gitRepo volume, an attacker can execute commands on the host system or other pods within the cluster. This can result in unauthorized access, data exfiltration, or privilege escalation, making it far more impactful than a moderate vulnerability.
Mitigation
Users can restrict the usage of gitRepo volumes in their cluster using policies such as `ValidatingAdmissionPolicy`.
The following CEL expression can be used as part of the policy to restrict the use of gitRepo volumes:
has(object.spec.volumes) || !object.spec.volumes.exists(v, has(v.gitRepo))

Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
