Executive Summary

[{'type': 'paragraph', 'content': 'CVE-2026-32140 is a remote code execution vulnerability in the Redshift JDBC driver used by the DataEase data visualization tool prior to version 2.10.20.'}, {'type': 'paragraph', 'content': 'The vulnerability arises because the driver aggressively searches for a configuration file named rsjdbc.ini, including allowing users to specify this file explicitly via the IniFile parameter in the JDBC URL.'}, {'type': 'paragraph', 'content': 'An attacker can exploit this by controlling the IniFile parameter to load a malicious configuration file containing dangerous JDBC properties. This can lead to the execution of arbitrary code on the server.'}, {'type': 'paragraph', 'content': "For example, a crafted ini file can abuse Spring's FileSystemXmlApplicationContext to load a remote XML configuration, which triggers remote code execution."}, {'type': 'paragraph', 'content': 'The vulnerability is fixed in DataEase and the Redshift JDBC driver version 2.10.20.'}] [1]

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary code remotely on the server running the vulnerable Redshift JDBC driver.

By exploiting the ability to load a malicious configuration file, an attacker can gain control over the affected system, potentially leading to data theft, system compromise, or further attacks within the network.

Since the vulnerability requires no authentication and can be triggered remotely, it poses a high risk to affected systems.

Detection Guidance

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by checking if your system or application is using a vulnerable version of the Redshift JDBC driver or DataEase prior to version 2.10.20.'}, {'type': 'paragraph', 'content': 'You can look for JDBC URLs that include the IniFile parameter, which may be exploited to load malicious configuration files.'}, {'type': 'paragraph', 'content': 'To detect potential exploitation attempts, monitor network traffic or logs for JDBC URLs containing the IniFile parameter or unusual references to rsjdbc.ini files.'}, {'type': 'paragraph', 'content': 'Suggested commands to help detect this vulnerability include:'}, {'type': 'list_item', 'content': "Search application configuration files or code for JDBC URLs containing 'IniFile=' parameter, e.g., using grep: grep -r 'IniFile=' /path/to/application"}, {'type': 'list_item', 'content': 'Check running processes or logs for usage of vulnerable Redshift JDBC driver versions prior to 2.10.20.'}, {'type': 'list_item', 'content': 'Monitor network traffic for suspicious JDBC URL parameters or unexpected connections to external resources specified in IniFile configurations.'}] [1]

Mitigation Strategies

The primary and recommended mitigation is to upgrade the Redshift JDBC driver and DataEase to version 2.10.20 or later, where this vulnerability is fixed.

Additionally, restrict or sanitize the IniFile parameter in JDBC URLs to prevent loading of arbitrary or attacker-controlled configuration files.

Implement input validation and filtering on any interfaces that accept JDBC URLs or datasource configurations to block malicious IniFile parameters.

Monitor and audit usage of the IniFile parameter and rsjdbc.ini files to detect and prevent unauthorized modifications or usage.
