CVE-2024-11079 is a vulnerability discovered in Ansible-Core, a widely used open-source automation tool for configuration management, application deployment, and task automation. The flaw stems from improper input validation related to the hostvars object, which is used within Ansible playbooks to reference variables from remote hosts. Specifically, attackers can leverage the hostvars object to bypass built-in unsafe content protections designed to prevent execution of arbitrary templated content. This bypass allows an attacker to inject and execute malicious templated code within playbooks if those playbooks incorporate remote data or module outputs without proper sanitization. The vulnerability can lead to arbitrary code execution on the system running the Ansible playbook, potentially compromising the confidentiality, integrity, and availability of the managed infrastructure. The CVSS 3.1 base score is 5.5 (medium severity), reflecting that exploitation requires network access, low privileges, and user interaction, but the impact scope is significant due to the potential for code execution and control over automated processes. No public exploits or active exploitation campaigns have been reported yet, but the risk remains given Ansible's extensive use in enterprise environments. The vulnerability highlights the importance of secure templating practices and input validation in automation tools that interact with dynamic data sources.

For European organizations, the impact of CVE-2024-11079 can be substantial, especially for those heavily reliant on Ansible for IT automation and orchestration. Successful exploitation could allow attackers to execute arbitrary code on systems responsible for managing critical infrastructure, leading to unauthorized access, data leakage, or disruption of services. This could affect cloud environments, data centers, and enterprise networks where Ansible automates deployment and configuration tasks. The compromise of automation workflows can cascade, impacting multiple systems and increasing the attack surface. Given the interconnected nature of European IT ecosystems and regulatory requirements such as GDPR, exploitation could also result in compliance violations and reputational damage. Organizations in sectors like finance, telecommunications, manufacturing, and government are particularly at risk due to their reliance on automated infrastructure management and the sensitivity of their data and services.

To mitigate CVE-2024-11079, European organizations should: 1) Immediately update Ansible-Core to the latest patched version once available, as no official patches are currently linked but monitoring vendor advisories is critical. 2) Audit existing playbooks to identify and sanitize any use of the hostvars object, especially where remote data or module outputs are templated. 3) Implement strict input validation and sanitization for all variables used in templating to prevent injection of malicious content. 4) Limit the use of dynamic templating with untrusted or external data sources within playbooks. 5) Employ role-based access controls to restrict who can modify or execute playbooks, reducing the risk of insider threats. 6) Monitor Ansible execution logs and system behavior for anomalies indicative of exploitation attempts. 7) Educate DevOps and security teams on secure templating practices and the risks associated with improper input validation in automation tools. 8) Consider isolating automation environments to minimize potential lateral movement in case of compromise.
