Attack-Flow Graph

Impact Analysis

The vulnerability can lead to unauthorized access to data stored in PVCs across different namespaces. An attacker can clone PVCs from any namespace by creating a DataImportCron resource in their own namespace, potentially exposing sensitive data and compromising data confidentiality. [2]

Executive Summary

This vulnerability in KubeVirt Containerized Data Importer (CDI) allows a user to clone PersistentVolumeClaims (PVCs) from namespaces they are not authorized to access. It occurs because the DataImportCron controller does not properly enforce namespace boundaries when handling PVC sources, enabling unauthorized cross-namespace PVC cloning. [2]

Mitigation Strategies

To mitigate this vulnerability, you should update to Red Hat OpenShift Virtualization release 4.19.17, which includes fixes for this issue. Additionally, ensure that all previously released relevant errata are applied before updating. This update addresses the unauthorized PVC cloning vulnerability in the virt-cdi-controller component. [1]

Compliance Impact

This vulnerability allows unauthorized access to data by enabling cloning of PersistentVolumeClaims (PVCs) across namespaces, which could lead to data breaches and unauthorized data exposure. Such unauthorized access to sensitive data may result in non-compliance with data protection regulations and standards like GDPR and HIPAA, which require strict controls on data access and confidentiality.
