CVE-2025-6819: Inventory Management System SQLi Flaw

CVE-2025-6819 Overview

A critical SQL Injection vulnerability has been identified in Code-projects Inventory Management System version 1.0. The vulnerability exists in the /php_action/removeBrand.php file where the brandId parameter is not properly sanitized before being used in SQL queries. This allows remote attackers to inject malicious SQL statements, potentially leading to unauthorized data access, modification, or deletion of database contents.

Critical Impact

Remote attackers can exploit this SQL Injection vulnerability to extract sensitive data, modify database records, or potentially gain unauthorized access to the underlying system through database manipulation.

Technical Details for CVE-2025-6819

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) stems from improper neutralization of special elements used in SQL commands within the /php_action/removeBrand.php endpoint. The vulnerable parameter brandId is directly incorporated into SQL queries without adequate input validation or parameterized query implementation. An attacker can exploit this remotely over the network without requiring authentication or user interaction, making it accessible to unauthenticated threat actors.

The vulnerability also maps to CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating the broader injection flaw category this vulnerability belongs to.

Root Cause

The root cause of this vulnerability is the failure to implement proper input sanitization and parameterized queries in the removeBrand.php file. When the application receives the brandId parameter from user input, it constructs SQL queries by directly concatenating the user-supplied value rather than using prepared statements or parameterized queries. This allows attackers to break out of the intended SQL context and inject arbitrary SQL commands.

Attack Vector

The attack can be launched remotely over the network. An attacker can craft malicious HTTP requests to the /php_action/removeBrand.php endpoint with specially crafted brandId parameter values containing SQL injection payloads. Successful exploitation could allow attackers to:

• Extract sensitive data from the database (usernames, passwords, inventory data)
• Modify or delete database records
• Bypass authentication mechanisms
• Potentially execute operating system commands through SQL injection techniques like xp_cmdshell (depending on database configuration)

The exploit has been disclosed publicly and may be actively used. Additional technical details can be found in the GitHub CVE Issue Tracker and VulDB #314257.

Detection Methods for CVE-2025-6819

Indicators of Compromise

• Unusual or malformed requests to /php_action/removeBrand.php containing SQL syntax characters such as single quotes, semicolons, or SQL keywords
• Database error messages in application logs indicating syntax errors or unexpected query behavior
• Unexpected database queries or data access patterns in database audit logs
• Anomalous outbound data transfers that may indicate data exfiltration

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to the vulnerable endpoint
• Implement application-level logging to capture all requests to /php_action/removeBrand.php and analyze for injection attempts
• Enable database query logging and monitor for unusual SELECT, UNION, or data extraction queries
• Use intrusion detection systems (IDS) with SQL injection signature rules

Monitoring Recommendations

• Continuously monitor web server access logs for requests containing SQL injection payloads targeting the brandId parameter
• Set up alerts for database errors that may indicate failed SQL injection attempts
• Review database audit logs for unauthorized data access or modification patterns
• Monitor network traffic for large data exfiltration that could indicate successful exploitation

How to Mitigate CVE-2025-6819

Immediate Actions Required

• Remove or disable access to the /php_action/removeBrand.php endpoint until a patch is applied
• Implement network-level access controls to restrict access to the Inventory Management System to trusted networks only
• Deploy WAF rules specifically targeting SQL injection attempts on the brandId parameter
• Audit database access and review logs for evidence of prior exploitation

Patch Information

No official vendor patch has been published at this time. Monitor the Code Projects website for security updates. Organizations using this software should consider implementing the workarounds below or migrating to a more secure inventory management solution.

Workarounds

• Implement input validation on the brandId parameter to only accept numeric values
• Modify the application code to use prepared statements or parameterized queries for all database interactions
• Deploy a reverse proxy or WAF with SQL injection filtering capabilities in front of the application
• Restrict network access to the application using firewall rules, limiting exposure to trusted IP addresses only
