CVE-2025-70828: Datart v1.0.0-rc.3 RCE Vulnerability

CVE-2025-70828 Overview

A command injection vulnerability exists in Datart v1.0.0-rc.3 that allows attackers to execute arbitrary code via the url parameter in the JDBC configuration. This vulnerability stems from insufficient input validation in the JDBC connection string handling, enabling malicious actors with low-level privileges to inject and execute arbitrary system commands through crafted URL parameters.

Critical Impact

Authenticated attackers can achieve arbitrary code execution on the Datart server by manipulating JDBC connection URL parameters, potentially leading to complete system compromise, data exfiltration, or lateral movement within the network.

Technical Details for CVE-2025-70828

Vulnerability Analysis

This vulnerability is classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command), commonly known as OS Command Injection. The Datart application fails to properly sanitize user-supplied input in the JDBC connection URL parameter before passing it to the underlying database driver configuration. When users configure database connections through the JDBC interface, the application does not adequately validate or escape special characters and command sequences within the URL parameter.

The network-accessible nature of this vulnerability, combined with the low attack complexity and requirement for only basic authentication, makes it particularly dangerous for organizations running exposed Datart instances. Successful exploitation grants attackers the same privileges as the Datart application process, typically resulting in high impact to confidentiality, integrity, and availability of the affected system.

Root Cause

The root cause lies in the insufficient input validation of the JDBC URL parameter within Datart's database configuration module. The application directly incorporates user-controlled input into the JDBC connection string without proper sanitization, allowing injection of malicious parameters that can be interpreted as system commands by the MySQL Connector/J driver through features like custom query interceptors or connection property injection.

Attack Vector

This vulnerability is exploitable over the network by authenticated users with low privileges. An attacker can craft a malicious JDBC URL containing embedded command sequences that exploit MySQL Connector/J connection properties or interceptor classes. When the Datart application processes this crafted URL to establish a database connection, the injected commands are executed on the underlying operating system with the privileges of the application process.

The exploitation leverages MySQL Connector/J features such as connection property interceptors documented in the MySQL Connector/J Documentation. A proof-of-concept demonstrating this attack vector is available in the GitHub PoC Repository for CVE-2025-70828.

Detection Methods for CVE-2025-70828

Indicators of Compromise

• Unusual JDBC connection strings containing suspicious parameters such as autoDeserialize, queryInterceptors, or connectionCollation in application logs
• Unexpected process spawning from the Datart application process or its Java runtime
• Anomalous outbound network connections from the Datart server to unknown destinations
• Modified or new files in temporary directories or web-accessible locations created by the application user

Detection Strategies

• Monitor Datart application logs for JDBC connection configuration changes containing unusual URL parameters or encoded payloads
• Implement network detection rules for command-and-control traffic originating from Datart server instances
• Deploy endpoint detection to identify child process creation from Java processes running Datart
• Analyze database configuration audit logs for suspicious URL patterns or connection attempts to non-standard hosts

Monitoring Recommendations

• Enable verbose logging for JDBC connection establishment within the Datart application
• Configure SIEM alerts for patterns matching command injection attempts in JDBC URLs
• Monitor system calls and process trees originating from the Datart service account
• Implement file integrity monitoring on Datart configuration files and directories

How to Mitigate CVE-2025-70828

Immediate Actions Required

• Restrict network access to Datart administrative interfaces to trusted IP ranges only
• Review and audit all existing JDBC connection configurations for suspicious URL parameters
• Implement strict input validation on all user-supplied JDBC connection parameters at the application firewall level
• Consider temporarily disabling the JDBC configuration feature until a patch is available

Patch Information

At the time of publication, no vendor patch has been officially released for this vulnerability. Organizations should monitor the Datart project repository for security updates and apply patches immediately when available. In the interim, implement the recommended workarounds and detection strategies to reduce risk.

Workarounds

• Deploy a web application firewall (WAF) rule to filter and block suspicious JDBC URL parameters containing known dangerous patterns
• Implement network segmentation to isolate Datart instances from critical infrastructure
• Restrict database configuration privileges to only essential administrative users
• Disable or restrict MySQL Connector/J features such as autoDeserialize and custom interceptors at the JVM level using system properties

# Example: Disable dangerous MySQL Connector/J features via JVM arguments
# Add these arguments to the Datart startup configuration
JAVA_OPTS="-Dcom.mysql.cj.disableAllowMultiQueries=true -Dcom.mysql.cj.disableRuntimeInterceptors=true"

# Restrict network access using iptables (example)
iptables -A INPUT -p tcp --dport 8080 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
