CVE-2025-53005: DataEase Auth Bypass Vulnerability

CVE-2025-53005 Overview

CVE-2025-53005 is an Authorization Bypass vulnerability affecting DataEase, an open source business intelligence and data visualization tool. Prior to version 2.10.11, a bypass vulnerability exists in DataEase's PostgreSQL Data Source JDBC Connection Parameters. Specifically, the sslfactory and sslfactoryarg parameters can be manipulated to trigger a security bypass, allowing unauthorized actions within the application.

Critical Impact

This vulnerability allows unauthenticated remote attackers to bypass security controls via malicious JDBC connection parameters, potentially leading to unauthorized access to sensitive data or system compromise.

Affected Products

• DataEase versions prior to 2.10.11
• DataEase deployments utilizing PostgreSQL data source connections
• Systems with network-accessible DataEase instances

Technical Details for CVE-2025-53005

Vulnerability Analysis

This vulnerability falls under CWE-153 (Improper Neutralization of Input During Web Page Generation). The flaw resides in how DataEase handles PostgreSQL JDBC connection parameters, specifically the sslfactory and sslfactoryarg parameters. These parameters are designed to specify custom SSL socket factory classes for secure database connections. However, insufficient validation of these parameters allows attackers to inject malicious values that bypass intended security controls.

The network-accessible nature of this vulnerability, combined with no required authentication or user interaction, makes it particularly dangerous for internet-facing DataEase deployments. Successful exploitation could result in high impact to confidentiality, integrity, and availability of the affected system.

Root Cause

The root cause of this vulnerability is improper input validation and sanitization of JDBC connection parameters within DataEase's PostgreSQL data source configuration. The sslfactory parameter allows specification of a custom Java class that implements javax.net.ssl.SSLSocketFactory, while sslfactoryarg passes arguments to this factory. Without proper validation, attackers can specify arbitrary classes or manipulate factory arguments to achieve unintended code execution or bypass authentication mechanisms.

Attack Vector

The attack is network-based and can be executed remotely without authentication. An attacker can craft malicious JDBC connection strings containing specially crafted sslfactory and sslfactoryarg parameter values. When DataEase processes these connection parameters to establish a PostgreSQL data source connection, the malicious values are executed, bypassing security controls.

The vulnerability requires no user interaction and has low attack complexity, making it accessible to attackers with basic skills. The attack targets the data source configuration functionality within DataEase's web interface or API endpoints.

Since no verified code examples are available, technical exploitation details can be found in the GitHub Security Advisory (GHSA-99c4-h4fq-r23v).

Detection Methods for CVE-2025-53005

Indicators of Compromise

• Unusual PostgreSQL data source connection attempts containing sslfactory or sslfactoryarg parameters with non-standard values
• Unexpected class loading or instantiation errors in DataEase application logs related to SSL socket factories
• Unauthorized data source creation or modification activities in audit logs
• Network connections from DataEase servers to unexpected external endpoints

Detection Strategies

• Monitor DataEase application logs for data source configuration changes, particularly those involving PostgreSQL connections with custom SSL parameters
• Implement web application firewall (WAF) rules to detect and block requests containing suspicious sslfactory or sslfactoryarg parameter patterns
• Deploy SentinelOne Singularity Platform to detect anomalous process behavior and unauthorized class loading on systems running DataEase
• Review audit logs for unauthorized API calls to data source configuration endpoints

Monitoring Recommendations

• Enable verbose logging for DataEase data source operations and forward logs to a centralized SIEM
• Configure alerts for any modifications to PostgreSQL data source configurations
• Monitor network traffic from DataEase servers for unusual outbound connections that may indicate successful exploitation
• Implement file integrity monitoring on DataEase configuration files and directories

How to Mitigate CVE-2025-53005

Immediate Actions Required

• Upgrade DataEase to version 2.10.11 or later immediately
• Audit existing PostgreSQL data source configurations for suspicious sslfactory or sslfactoryarg parameter values
• Restrict network access to DataEase instances using firewall rules or network segmentation
• Review access logs for any signs of exploitation attempts prior to patching

Patch Information

DataEase has released version 2.10.11 which addresses this vulnerability. Organizations should update to this version or later as soon as possible. The patch implements proper validation and sanitization of JDBC connection parameters, preventing the bypass condition. For detailed patch information, refer to the GitHub Security Advisory.

Workarounds

• Deploy a reverse proxy or WAF in front of DataEase to filter requests containing sslfactory or sslfactoryarg parameters until patching is complete
• Disable or restrict access to PostgreSQL data source creation functionality if not required
• Implement network-level access controls to limit who can reach the DataEase administrative interface
• Consider temporarily taking internet-facing DataEase instances offline until the patch can be applied

# Example: Restrict network access to DataEase using iptables
# Allow only trusted networks to access DataEase on port 8100
iptables -A INPUT -p tcp --dport 8100 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 8100 -j DROP
