CVE-2025-53006: DataEase Information Disclosure Flaw

CVE-2025-53006 Overview

DataEase is an open source business intelligence and data visualization tool that contains a JDBC connection parameter injection vulnerability affecting PostgreSQL and Redshift database connections. Prior to version 2.10.11, attackers can exploit SSL factory parameters to achieve arbitrary class instantiation, potentially leading to remote code execution.

The vulnerability stems from improper handling of JDBC connection parameters. While previous security patches addressed socketfactory and socketfactoryarg parameters, similar dangerous parameters including sslfactory, sslfactoryarg, sslhostnameverifier, sslpasswordcallback, and authenticationPluginClassName remain exploitable.

Critical Impact

Unauthenticated attackers can exploit this vulnerability via network access to execute arbitrary code on affected DataEase instances by manipulating SSL factory parameters during database connection establishment.

Affected Products

• DataEase versions prior to 2.10.11
• DataEase installations using PostgreSQL database connections
• DataEase installations using Redshift database connections

Technical Details for CVE-2025-53006

Vulnerability Analysis

This vulnerability represents an Insecure Deserialization and Code Injection flaw classified under CWE-153 (Improper Neutralization of Input During Web Page Generation). The core issue lies in DataEase's handling of JDBC connection strings for PostgreSQL and Redshift database connections.

When establishing database connections, DataEase allows users to specify various connection parameters. The application previously patched socketfactory and socketfactoryarg parameters to prevent arbitrary class instantiation. However, the PostgreSQL JDBC driver supports additional parameters with equivalent dangerous functionality that were not adequately restricted.

The vulnerable parameters sslfactory and sslfactoryarg allow specification of custom SSL factory classes that get instantiated when establishing SSL connections. Unlike the socket factory parameters which are triggered immediately, these SSL-related parameters activate after the initial connection is established, providing a secondary attack vector that bypassed existing mitigations.

Root Cause

The root cause is insufficient input validation and sanitization of JDBC connection parameters in DataEase's database connection handling code. While the application implemented restrictions for some dangerous parameters, it failed to account for the full range of exploitable JDBC driver parameters.

The PostgreSQL JDBC driver supports multiple callback-style parameters that instantiate user-specified classes:

• sslfactory - Custom SSL socket factory class
• sslfactoryarg - Argument passed to SSL factory constructor
• sslhostnameverifier - Custom hostname verification class
• sslpasswordcallback - Custom password callback handler
• authenticationPluginClassName - Custom authentication plugin

Each of these parameters accepts a fully-qualified Java class name and instantiates it during the connection lifecycle, creating multiple injection points for attackers.

Attack Vector

The attack is network-accessible and requires no authentication or user interaction. An attacker can craft malicious connection parameters targeting any of the vulnerable JDBC settings to instantiate arbitrary Java classes present on the classpath. This enables remote code execution by leveraging gadget chains present in the application's dependencies.

The key differentiation of this attack from previous patches is that the SSL factory parameters only trigger after the connection handshake begins, making them effective bypass techniques for socket factory restrictions.

Detection Methods for CVE-2025-53006

Indicators of Compromise

• Unusual database connection attempts containing sslfactory or sslfactoryarg parameters in connection strings
• Connection strings with sslhostnameverifier, sslpasswordcallback, or authenticationPluginClassName parameters
• Unexpected Java class instantiation errors in DataEase logs related to SSL handling
• Network connections to unusual endpoints following database connection attempts

Detection Strategies

• Monitor DataEase application logs for connection strings containing dangerous JDBC parameters
• Implement web application firewall rules to inspect and block requests containing sslfactory, sslfactoryarg, or related parameter names
• Review database connection configurations for any non-standard SSL factory class specifications
• Deploy endpoint detection to identify suspicious process spawning from DataEase Java processes

Monitoring Recommendations

• Enable verbose logging for database connection establishment in DataEase
• Configure SIEM alerts for JDBC connection parameter manipulation patterns
• Monitor for outbound network connections from the DataEase server to unexpected destinations
• Track Java classloader activity for instantiation of unusual classes during database operations

How to Mitigate CVE-2025-53006

Immediate Actions Required

• Upgrade DataEase to version 2.10.11 or later immediately
• Review existing database connection configurations for any suspicious SSL factory parameters
• Implement network segmentation to restrict DataEase's outbound connectivity
• Enable additional logging to capture connection parameter details for forensic review

Patch Information

DataEase has released version 2.10.11 which addresses this vulnerability by implementing proper validation and restriction of dangerous JDBC connection parameters. Organizations should upgrade to this version as the primary mitigation.

For detailed patch information and security advisory, refer to the DataEase GitHub Security Advisory.

Workarounds

• Implement input validation at the network layer to block requests containing dangerous JDBC parameters such as sslfactory, sslfactoryarg, sslhostnameverifier, sslpasswordcallback, and authenticationPluginClassName
• Restrict network access to DataEase administrative interfaces using firewall rules or access control lists
• Deploy a web application firewall with custom rules to inspect and sanitize database connection parameters
• Consider temporarily disabling PostgreSQL and Redshift data source creation until the patch is applied

# Example: Block dangerous parameters at reverse proxy level (nginx)
# Add to location block serving DataEase
