Apache Ranger is vulnerable to an unauthenticated SQL injection attack that could lead to full system compromise and unauthorized data access.

This flaw is an improper neutralization of special elements used in an SQL command (CWE-89), which permits an unauthenticated attacker to inject malicious SQL queries into the application.

Successful exploitation of this vulnerability allows for unauthorized access to sensitive data, modification of database contents, or administrative disruption of the Apache Ranger service. Given the CVSS score of 9.8, this represents a critical risk that could result in a complete breach of security controls and loss of data integrity across the enterprise security infrastructure.

Immediate Action: Administrators must upgrade Apache Ranger to version 2.9.0 or later as recommended by the vendor.

Proactive Monitoring: Security teams should monitor database logs for anomalous query patterns, unexpected SQL syntax errors, or unauthorized access attempts originating from external or untrusted network segments.

Compensating Controls: Deploy a Web Application Firewall (WAF) with specific rulesets to detect and block common SQL injection patterns until the software can be patched in production environments.

Public Exploit Available: Unknown

The critical nature of this vulnerability, combined with the lack of required authentication for exploitation, necessitates immediate attention. Organizations utilizing Apache Ranger should prioritize the update to version 2.9.0 to eliminate this vector for remote code execution and unauthorized data exfiltration.
