CVE-2024-45496 is a critical security vulnerability identified in OpenShift Container Platform version 4.12.0. The flaw arises from improper privilege management during the build initialization phase, where the git-clone container is executed with a privileged security context. This elevated privilege grants the container unrestricted access to the underlying node, which is a significant security risk. An attacker possessing developer-level access can exploit this by supplying a specially crafted .gitconfig file. This file can contain commands that are executed during the git cloning process, enabling arbitrary command execution on the worker node hosting the container. The vulnerability effectively allows an attacker to escalate privileges from a containerized environment to the host node, compromising the node’s security. The CVSS v3.1 score is 9.9, reflecting critical severity due to network exploitability (AV:N), low attack complexity (AC:L), requiring only low privileges (PR:L), no user interaction (UI:N), and a scope change (S:C) that affects confidentiality, integrity, and availability (C:H/I:H/A:L). This vulnerability can lead to full system compromise, data breaches, and disruption of containerized workloads. No public exploits have been reported yet, but the risk is high given the ease of exploitation and the widespread use of OpenShift in enterprise environments.

For European organizations, the impact of CVE-2024-45496 is significant. OpenShift is widely used across Europe for container orchestration in both private and public cloud environments. Exploitation could lead to unauthorized access to sensitive data, disruption of critical applications, and potential lateral movement within corporate networks. The ability to execute arbitrary commands on worker nodes undermines the security boundary between containers and the host, increasing the risk of full infrastructure compromise. Industries such as finance, healthcare, telecommunications, and government, which rely heavily on containerized applications and OpenShift, face heightened risks of data breaches and operational outages. Additionally, regulatory frameworks like GDPR impose strict requirements on data protection, making exploitation consequences more severe in terms of compliance and potential fines. The threat also poses risks to supply chain security where OpenShift is used to build and deploy software artifacts.

To mitigate CVE-2024-45496, organizations should immediately upgrade OpenShift to a patched version once available from Red Hat. Until patches are applied, restrict developer-level access to the build process and audit all .gitconfig files used during builds for suspicious commands. Implement strict security context constraints to prevent containers from running in privileged mode unnecessarily, especially the git-clone container. Employ runtime security tools to monitor container behavior and detect anomalous command executions. Use network segmentation to limit access to build nodes and enforce the principle of least privilege across the CI/CD pipeline. Regularly review and harden build configurations and container security policies. Additionally, consider deploying container security platforms that can enforce policy controls and provide visibility into container privilege escalations. Conduct security awareness training for developers on the risks of supplying untrusted configuration files in build processes.
