CVE-2024-45784: Apache Airflow Vulnerability Exposes Sensitive Data in Logs
A vulnerability in the popular workflow management platform Apache Airflow could inadvertently expose sensitive configuration data, potentially compromising system security.
The flaw, tracked as CVE-2024-45784 and assigned a CVSS score of 7.5 (high severity), affects all Airflow versions prior to 2.10.3. It stems from the platform’s failure to mask sensitive configuration values in task logs by default.
This oversight means that Directed Acyclic Graph (DAG) authors could unintentionally, or even intentionally, log sensitive information such as API keys, database credentials, or other critical secrets. If unauthorized users gain access to these logs, they could exploit this exposed data to compromise the entire Airflow deployment.
The Risk:
- Data breaches: Attackers could gain access to confidential information, including customer data, financial records, or proprietary code.
- System compromise: Exposed credentials could allow attackers to gain control of critical systems and infrastructure.
- Lateral movement: Attackers could leverage compromised systems to pivot and access other parts of the network.
Mitigation:
The Apache Airflow team has addressed this vulnerability in version 2.10.3. All users are strongly advised to upgrade to this version or later immediately.
Furthermore, organizations should review their Airflow logs for any potentially exposed secrets. If sensitive information is found, it is crucial to rotate those secrets as a precautionary measure.
