Executive brief
Apache Ranger is an open-source platform for managing user access and permissions across Hadoop clusters and other enterprise data platforms. A JDBC URL injection vulnerability allows attackers to execute arbitrary code remotely on systems running affected versions, potentially compromising all data managed by Ranger and the underlying Hadoop infrastructure.
Technical details
The vulnerability exists in Apache Ranger versions 2.8.0 and earlier and is exploited via JDBC URL injection. An attacker can inject malicious commands through JDBC URL parameters without requiring authentication or special privileges. The root cause lies in improper input validation and sanitization of JDBC connection strings. Successful exploitation allows remote code execution with the privileges of the Ranger service process, potentially leading to full system compromise. The fix is available in version 2.9.0 and later.
