CVE-2025-6132: Chanjet CRM SQL Injection Vulnerability

CVE-2025-6132 Overview

A critical SQL injection vulnerability has been identified in Chanjet CRM version 1.0. The vulnerability exists in the /sysconfig/departmentsetting.php file, where the gblOrgID parameter is improperly validated before being used in SQL queries. This flaw allows remote attackers to inject malicious SQL statements, potentially leading to unauthorized data access, modification, or deletion within the CRM database.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive customer data, modify database records, or potentially gain further access to the underlying system through database-level attacks.

Technical Details for CVE-2025-6132

Vulnerability Analysis

This SQL injection vulnerability stems from insufficient input validation in the department settings functionality of Chanjet CRM. The gblOrgID parameter in /sysconfig/departmentsetting.php is directly incorporated into SQL queries without proper sanitization or parameterization. This allows attackers to craft malicious input that alters the intended SQL query structure, enabling them to execute arbitrary SQL commands against the backend database.

The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating fundamental flaws in how user-supplied input is processed before database interaction.

Root Cause

The root cause of this vulnerability is the lack of proper input sanitization and the absence of parameterized queries (prepared statements) in the affected PHP file. When the gblOrgID parameter value is received from user input, it is directly concatenated into SQL query strings rather than being properly escaped or bound as a parameter. This classic coding mistake allows attackers to break out of the intended query context and inject their own SQL commands.

Attack Vector

The attack can be launched remotely over the network without requiring authentication. An attacker can send specially crafted HTTP requests to the /sysconfig/departmentsetting.php endpoint with malicious SQL payloads in the gblOrgID parameter. Since the exploit has been publicly disclosed, attackers have access to the technical details needed to develop working exploits.

The exploitation mechanism involves injecting SQL metacharacters and commands through the vulnerable parameter to manipulate database queries. This could enable attackers to perform UNION-based attacks to extract data from other tables, time-based blind injection to enumerate database contents, or stacked queries to modify or delete data depending on the database configuration.

Detection Methods for CVE-2025-6132

Indicators of Compromise

• Unusual or malformed requests to /sysconfig/departmentsetting.php containing SQL syntax characters such as single quotes, double dashes, UNION keywords, or semicolons in the gblOrgID parameter
• Database logs showing unexpected queries, errors, or time delays associated with the department settings functionality
• Web application firewall logs indicating blocked SQL injection attempts targeting Chanjet CRM endpoints

Detection Strategies

• Deploy web application firewall (WAF) rules to detect and block SQL injection patterns in requests to /sysconfig/departmentsetting.php
• Implement database activity monitoring to alert on anomalous query patterns, particularly those originating from the CRM application
• Enable detailed logging for the Chanjet CRM application and monitor for suspicious parameter values in the gblOrgID field

Monitoring Recommendations

• Establish baseline traffic patterns for the department settings endpoint and alert on deviations
• Configure intrusion detection systems (IDS) with signatures for common SQL injection attack strings
• Regularly review database audit logs for unauthorized data access or modification attempts

How to Mitigate CVE-2025-6132

Immediate Actions Required

• Restrict network access to the Chanjet CRM application to trusted IP addresses only until a patch is available
• Implement web application firewall rules specifically blocking SQL injection patterns in the gblOrgID parameter
• Consider temporarily disabling or restricting access to the /sysconfig/departmentsetting.php functionality if business operations permit

Patch Information

At the time of this writing, no official patch information has been published by Chanjet. Organizations should monitor the vendor's official channels and the VulDB entry for updates on available fixes. The GitHub issue discussion may also contain additional technical details about the vulnerability.

Workarounds

• Deploy a reverse proxy or WAF with strict input validation rules to filter malicious SQL injection payloads before they reach the application
• Implement network segmentation to limit the exposure of the CRM system to untrusted networks
• If source code access is available, implement prepared statements or parameterized queries for the affected gblOrgID parameter as a manual remediation
