CVE-2024-8775 is a vulnerability identified in Ansible version 1.0.0 where sensitive information contained within Ansible Vault files can be inadvertently exposed in plaintext during the execution of playbooks. The root cause lies in the usage of tasks such as include_vars to load vaulted variables without the no_log: true parameter. When no_log is not set to true, the sensitive data is outputted in the playbook logs or standard output, which can be captured by anyone with access to these logs. This exposure risks revealing critical secrets like passwords, API keys, or other confidential credentials that are meant to be protected by Ansible Vault encryption. The vulnerability requires an attacker to have at least low-level privileges on the system running the playbook, as the attack vector involves local execution and log access. There is no requirement for user interaction, and the flaw does not affect the integrity or availability of the system, only confidentiality. No public exploits have been reported yet, but the risk remains significant in environments where logs are not properly secured or monitored. The CVSS 3.1 score of 5.5 reflects a medium severity with a vector indicating local attack vector, low complexity, low privileges required, no user interaction, and a high impact on confidentiality. This vulnerability highlights the importance of secure playbook design and proper use of Ansible’s no_log feature to prevent accidental leakage of secrets during automation workflows.

For European organizations, the exposure of sensitive information such as passwords and API keys in plaintext logs can lead to unauthorized access to critical infrastructure, cloud environments, or internal systems. This can facilitate lateral movement, privilege escalation, or data breaches if attackers gain access to logs or output files. Organizations relying heavily on Ansible for automation, especially in sectors like finance, healthcare, and critical infrastructure, face increased risk due to the potential compromise of confidential credentials. The impact is primarily on confidentiality, with no direct effect on system integrity or availability. However, the indirect consequences of leaked secrets can be severe, including regulatory non-compliance (e.g., GDPR), reputational damage, and operational disruption. Since the vulnerability requires local access with low privileges, insider threats or attackers who have already compromised a low-privilege account could exploit this flaw to escalate their access. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially in environments with poor log management or insufficient access controls.

To mitigate CVE-2024-8775, European organizations should: 1) Review all Ansible playbooks and ensure that any task loading vaulted variables (e.g., include_vars) explicitly sets no_log: true to prevent sensitive data from being logged. 2) Implement strict access controls on systems running Ansible playbooks and on log storage locations to limit who can view playbook output and logs. 3) Regularly audit logs and outputs for accidental exposure of secrets and rotate any credentials found in logs immediately. 4) Educate DevOps and automation teams on secure Ansible practices, emphasizing the importance of no_log and secure handling of vaulted secrets. 5) Where possible, upgrade Ansible to versions beyond 1.0.0 if patches addressing this vulnerability become available. 6) Employ centralized logging solutions with encryption and access controls to reduce the risk of unauthorized log access. 7) Integrate secret scanning tools in CI/CD pipelines to detect accidental secret exposure before deployment. These steps go beyond generic advice by focusing on secure playbook design, operational controls, and proactive detection.
