CVE-2025-62419: DataEase JDBC URL Injection Vulnerability

CVE-2025-62419 Overview

CVE-2025-62419 is a JDBC URL injection vulnerability affecting DataEase, a popular data visualization and analytics platform. The vulnerability exists in the DB2 and MongoDB data source configuration handlers within DataEase versions through 2.10.13. When the extraParams field is empty, the HOSTNAME, PORT, and DATABASE values are directly concatenated into the JDBC URL without proper filtering of illegal parameters. This allows an attacker to inject malicious JDBC strings into the HOSTNAME field, effectively bypassing previously patched vulnerabilities CVE-2025-57773 and CVE-2025-58045.

Critical Impact

Attackers can exploit this vulnerability to inject malicious JDBC connection strings, potentially leading to unauthorized data access, data manipulation, or further compromise of connected database systems through crafted payloads.

Affected Products

• DataEase versions through 2.10.13
• DB2 data source configuration handler
• MongoDB data source configuration handler

Technical Details for CVE-2025-62419

Vulnerability Analysis

This vulnerability represents a classic input validation failure in the data source configuration workflow. The DB2 and MongoDB handlers within DataEase fail to properly sanitize user-supplied input when constructing JDBC connection URLs. Specifically, when the extraParams field is left empty by the user, the application directly concatenates the HOSTNAME, PORT, and DATABASE parameters into the final JDBC URL string without any filtering or validation of special characters or injection payloads.

The vulnerability is particularly concerning because it serves as a bypass for two previously patched vulnerabilities (CVE-2025-57773 and CVE-2025-58045), indicating that the initial remediation efforts were insufficient and did not address all attack vectors. This pattern of incomplete patches is a common security anti-pattern that demonstrates the importance of comprehensive input validation across all code paths.

The CWE-502 (Deserialization of Untrusted Data) classification suggests that the injected JDBC parameters may enable deserialization attacks against the underlying database drivers, which could lead to remote code execution in certain configurations.

Root Cause

The root cause of CVE-2025-62419 lies in the conditional validation logic within the data source handlers. The application appears to only apply input sanitization when extraParams contains values, creating a vulnerable code path when this field is empty. The direct string concatenation of user-controlled values (HOSTNAME, PORT, DATABASE) into JDBC URLs without proper escaping or allowlist validation enables attackers to inject arbitrary JDBC connection parameters and potentially malicious payloads.

Attack Vector

The attack is network-based and can be executed by an unauthenticated attacker who has access to the DataEase data source configuration interface. The attacker crafts a malicious hostname value containing JDBC injection payloads and submits it through the DB2 or MongoDB data source configuration form with an empty extraParams field.

The injected payload becomes part of the constructed JDBC URL, which is then processed by the database driver. Depending on the specific payload and driver capabilities, this could lead to unauthorized data access, connection hijacking, or in severe cases involving vulnerable JDBC drivers, remote code execution through deserialization attacks.

The attack requires the extraParams field to be empty to trigger the vulnerable code path that bypasses the previously implemented security controls.

Detection Methods for CVE-2025-62419

Indicators of Compromise

• Unusual or malformed hostname values in DataEase data source configurations containing JDBC parameters or special characters
• Database connection attempts with unexpected connection strings or parameters
• Errors in DataEase logs related to malformed JDBC URLs or connection failures
• Unexpected network connections from the DataEase server to external or unauthorized database endpoints

Detection Strategies

• Monitor DataEase application logs for data source configuration changes, particularly those involving DB2 or MongoDB handlers
• Implement network monitoring to detect anomalous database connection patterns originating from the DataEase server
• Deploy web application firewall (WAF) rules to detect JDBC injection patterns in form submissions
• Review audit logs for data source configuration modifications by unauthorized users

Monitoring Recommendations

• Enable verbose logging for data source configuration operations in DataEase
• Implement real-time alerting for any new data source configurations or modifications
• Monitor outbound database connections from the DataEase application server for connections to unexpected hosts
• Regularly audit existing data source configurations for signs of injection attempts

How to Mitigate CVE-2025-62419

Immediate Actions Required

• Upgrade DataEase to version 2.10.14 or later immediately, as this version contains the official fix
• Audit existing data source configurations for any suspicious or malformed hostname values
• Restrict access to the data source configuration interface to trusted administrators only
• Implement network segmentation to limit database connectivity from the DataEase server

Patch Information

The vulnerability has been fixed in DataEase version 2.10.14. The fix is available through the official GitHub commit. Organizations should update to this version or later as soon as possible. Additional details about the vulnerability and remediation can be found in the GitHub Security Advisory GHSA-x4x9-mjcf-99r9.

Workarounds

• According to the vendor advisory, no known workarounds exist for this vulnerability
• As a temporary measure, restrict network access to the DataEase administration interface
• Consider disabling DB2 and MongoDB data source configuration capabilities until the patch can be applied
• Implement strict input validation at the network perimeter using a WAF to filter potential injection attempts

# Verify DataEase version after upgrade
# Check that you are running version 2.10.14 or later
docker exec dataease cat /opt/dataease/conf/version.txt
# Or check via the application's system information panel
