CVE-2025-15442: CRMEB SQL Injection Vulnerability

CVE-2025-15442 Overview

A SQL injection vulnerability has been identified in CRMEB, a popular open-source e-commerce management system. This vulnerability affects the /adminapi/export/product_list endpoint, where improper handling of the cate_id parameter allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely by authenticated users with administrative privileges, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Authenticated attackers can leverage this SQL injection vulnerability to extract sensitive data from the database, modify records, or potentially escalate their access within the CRMEB system.

Affected Products

• CRMEB versions up to and including 5.6.1

Technical Details for CVE-2025-15442

Vulnerability Analysis

This vulnerability is classified as CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), manifesting specifically as a SQL injection flaw. The vulnerable endpoint /adminapi/export/product_list fails to properly sanitize the cate_id parameter before incorporating it into SQL queries.

While the vulnerability requires high-level privileges (administrative access) to exploit, successful attacks can compromise the confidentiality, integrity, and availability of the underlying database. The network-accessible nature of this endpoint means any authenticated administrator with network access to the CRMEB instance could potentially exploit this vulnerability.

The vendor was contacted early about this disclosure but did not respond, leaving users without an official patch at the time of publication.

Root Cause

The root cause of this vulnerability lies in insufficient input validation and the lack of parameterized queries in the product export functionality. The cate_id parameter is directly interpolated into SQL statements without proper sanitization or prepared statement usage, allowing specially crafted input to manipulate the query structure.

Attack Vector

The attack is network-based and targets the administrative API endpoint /adminapi/export/product_list. An attacker with valid administrative credentials can manipulate the cate_id parameter to inject arbitrary SQL commands. While the requirement for administrative privileges limits the attack surface, compromised admin accounts or insider threats could leverage this vulnerability to:

• Extract sensitive customer data, order information, or financial records
• Modify product prices, inventory, or user permissions
• Delete critical database records
• Potentially gain access to underlying system resources depending on database configuration

The vulnerability mechanism involves injecting malicious SQL syntax through the cate_id parameter. Technical details and proof-of-concept information are available in the GitHub PoC Repository.

Detection Methods for CVE-2025-15442

Indicators of Compromise

• Unusual or malformed requests to /adminapi/export/product_list containing SQL syntax characters such as single quotes, semicolons, or UNION keywords in the cate_id parameter
• Database error messages or unexpected responses from the product export endpoint
• Anomalous database query patterns showing unauthorized table access or data exfiltration
• Suspicious administrative account activity, particularly around export functionality

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in API requests targeting /adminapi/export/product_list
• Enable detailed logging for the CRMEB administrative API and monitor for suspicious parameter values
• Deploy database activity monitoring to detect unusual queries originating from the CRMEB application
• Configure alerting for failed SQL queries or database errors associated with the product export functionality

Monitoring Recommendations

• Review access logs for the /adminapi/export/product_list endpoint for signs of exploitation attempts
• Monitor database query logs for injection patterns including UNION SELECT, comment sequences (--), or stacked queries
• Implement rate limiting on export endpoints to slow potential automated exploitation
• Set up alerts for any database errors or exceptions originating from the product list export feature

How to Mitigate CVE-2025-15442

Immediate Actions Required

• Restrict access to the /adminapi/export/product_list endpoint to only trusted IP addresses or VPN connections
• Review and audit all administrative user accounts for any unauthorized access or suspicious activity
• Consider temporarily disabling the product export functionality until a patch is available
• Implement input validation at the application or WAF level to filter SQL injection attempts targeting the cate_id parameter

Patch Information

No official patch has been released by the CRMEB vendor at this time. The vendor was contacted early about this disclosure but did not respond. Users are advised to monitor the official CRMEB repository and VulDB entry for updates regarding a security fix.

Workarounds

• Deploy a Web Application Firewall (WAF) with SQL injection detection rules specifically monitoring the cate_id parameter
• Implement network-level access controls to limit who can reach the administrative API endpoints
• If possible, modify the CRMEB source code to use parameterized queries for the affected endpoint
• Consider using database user permissions to restrict the CRMEB application's database access to minimum required privileges
