CVE-2025-14189: Chanjet CRM SQL Injection Vulnerability

CVE-2025-14189 Overview

A SQL injection vulnerability has been identified in Chanjet CRM versions up to 20251121. The vulnerability affects the file /tools/jxf_dump_table_demo.php, where improper handling of the gblOrgID parameter allows attackers to inject malicious SQL commands. This flaw can be exploited remotely without authentication, potentially allowing unauthorized access to sensitive database information.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete data from the underlying database, potentially compromising the entire CRM system and exposing sensitive customer information.

Affected Products

• Chanjet CRM up to version 20251121

Technical Details for CVE-2025-14189

Vulnerability Analysis

This vulnerability represents a classic SQL injection flaw (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) in the Chanjet CRM application. The affected endpoint /tools/jxf_dump_table_demo.php accepts user-supplied input through the gblOrgID parameter without proper sanitization or parameterized queries.

The vulnerability allows network-based attacks that require no authentication or user interaction, making it accessible to any remote attacker who can reach the vulnerable endpoint. The impact affects confidentiality, integrity, and availability of the database contents, though the overall scope is limited to the vulnerable component itself.

The vendor was contacted about this disclosure but did not respond, leaving users without an official patch at the time of publication. The exploit has been made public, increasing the risk of active exploitation.

Root Cause

The root cause of this vulnerability is improper input validation and lack of parameterized queries in the PHP code handling the gblOrgID parameter. The application directly incorporates user-supplied data into SQL queries without adequate sanitization, escaping, or the use of prepared statements. This allows attackers to break out of the intended query structure and inject arbitrary SQL commands.

Attack Vector

The attack can be performed remotely over the network against the vulnerable PHP endpoint. An attacker can craft a malicious HTTP request to /tools/jxf_dump_table_demo.php with a specially crafted gblOrgID parameter containing SQL injection payloads. Since no authentication is required, any attacker with network access to the Chanjet CRM instance can attempt exploitation.

Typical exploitation techniques include:

• Union-based SQL injection to extract data from other tables
• Boolean-based blind injection to enumerate database contents
• Time-based blind injection when direct output is not available
• Stacked queries (if supported by the database configuration) to modify or delete data

Detection Methods for CVE-2025-14189

Indicators of Compromise

• Unusual or malformed requests to /tools/jxf_dump_table_demo.php containing SQL syntax in the gblOrgID parameter
• Web server logs showing requests with common SQL injection patterns such as UNION SELECT, OR 1=1, single quotes, or comment sequences (--, /**/)
• Database logs indicating unexpected query failures, syntax errors, or unauthorized data access attempts
• Anomalous database query patterns or unusual data retrieval volumes from the CRM database

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting the gblOrgID parameter
• Implement intrusion detection system (IDS) signatures for common SQL injection attack patterns in HTTP traffic
• Enable detailed logging on web servers and database servers to capture suspicious query activity
• Monitor for access to /tools/jxf_dump_table_demo.php from unexpected IP addresses or at unusual times

Monitoring Recommendations

• Configure alerts for HTTP requests containing SQL metacharacters in parameter values
• Establish baseline database query patterns and alert on deviations that may indicate SQL injection exploitation
• Review web server access logs regularly for reconnaissance or exploitation attempts against CRM endpoints
• Implement database activity monitoring to track unusual SELECT, UPDATE, or DELETE operations

How to Mitigate CVE-2025-14189

Immediate Actions Required

• Restrict network access to the vulnerable endpoint /tools/jxf_dump_table_demo.php using firewall rules or web server configuration
• If the endpoint is not required for business operations, disable or remove the file entirely
• Deploy WAF rules to block requests containing SQL injection payloads in the gblOrgID parameter
• Review database user privileges and apply principle of least privilege to limit potential impact

Patch Information

No official patch is currently available from the vendor. The vendor was contacted about this vulnerability but did not respond. Organizations should monitor the VulDB entry and vendor communications for any future security updates.

In the absence of an official patch, organizations must rely on compensating controls and workarounds to reduce risk.

Workarounds

• Remove or rename the vulnerable file /tools/jxf_dump_table_demo.php if it is not essential for production operations
• Implement strict input validation at the web server or reverse proxy level to reject requests with suspicious characters
• Use a WAF to filter SQL injection attempts before they reach the application
• Restrict access to the /tools/ directory to authorized IP addresses only
