CVE-2025-6668: Inventory Management System SQLi Vulnerability

CVE-2025-6668 Overview

A SQL injection vulnerability has been discovered in code-projects Inventory Management System version 1.0. The vulnerability exists in the /php_action/fetchSelectedBrand.php file where the brandId parameter is improperly handled, allowing attackers to inject malicious SQL statements. This flaw enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact
Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive data, modify or delete database records, and potentially compromise the entire inventory management system.

Technical Details for CVE-2025-6668

Vulnerability Analysis

This SQL injection vulnerability stems from improper input validation in the fetchSelectedBrand.php file. The application fails to properly sanitize or parameterize the brandId argument before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL commands that are then executed by the database server with the application's privileges.

The vulnerability is classified under CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output). The network-based attack vector means that exploitation can occur remotely without any user interaction or authentication requirements, making it accessible to any attacker who can reach the vulnerable endpoint.

Root Cause

The root cause of this vulnerability is the direct use of user-supplied input (the brandId parameter) in SQL query construction without proper sanitization, escaping, or the use of parameterized queries (prepared statements). The PHP code likely concatenates the user input directly into the SQL query string, creating a classic SQL injection vulnerability pattern.

Attack Vector

The attack is initiated remotely through the network by sending crafted HTTP requests to the /php_action/fetchSelectedBrand.php endpoint. An attacker would manipulate the brandId parameter to include malicious SQL syntax, such as single quotes, UNION statements, or conditional logic operators. Since no authentication is required, any network-accessible attacker can attempt exploitation.

The exploit has been publicly disclosed, as documented in the GitHub Issue for CVE. Attackers can leverage standard SQL injection techniques including UNION-based injection to extract data from other tables, boolean-based blind injection to infer database contents, or time-based blind injection for scenarios where direct output is not available.

Detection Methods for CVE-2025-6668

Indicators of Compromise

Unusual or malformed requests to /php_action/fetchSelectedBrand.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords
Database error messages in application logs indicating SQL syntax errors
Unexpected database queries or access patterns originating from the web application
Evidence of data exfiltration or unauthorized modifications in database audit logs

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the brandId parameter
Monitor web server access logs for requests containing SQL injection payloads directed at fetchSelectedBrand.php
Deploy database activity monitoring to detect anomalous queries that deviate from expected application behavior
Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

Enable detailed logging on web servers and database servers to capture request parameters and query execution
Set up alerts for repeated failed SQL queries or syntax errors that may indicate injection attempts
Monitor for unusual data access patterns such as bulk data extraction or access to tables not typically queried by the application
Implement real-time log analysis using SIEM solutions to correlate web and database events

How to Mitigate CVE-2025-6668

Immediate Actions Required

Remove or restrict access to the vulnerable /php_action/fetchSelectedBrand.php file until a patch is applied
Implement input validation to whitelist only numeric values for the brandId parameter
Deploy a Web Application Firewall (WAF) rule to filter SQL injection attempts targeting this endpoint
Review database permissions to limit the application's database user to only necessary privileges (principle of least privilege)

Patch Information

As of the last update on 2025-06-27, no official patch has been released by code-projects for this vulnerability. Organizations using the Inventory Management System should implement the workarounds listed below and monitor the Code Projects website for security updates.

For additional technical details and vulnerability tracking, refer to:

Workarounds

Implement prepared statements (parameterized queries) in the fetchSelectedBrand.php file to prevent SQL injection
Add strict input validation to ensure brandId only accepts integer values
Deploy network-level restrictions to limit access to the inventory management system to trusted IP addresses only
Consider disabling or removing the vulnerable functionality if it is not business-critical

bash

# Configuration example for Apache mod_security WAF rule
# Add to .htaccess or Apache configuration to block SQL injection attempts
SecRule ARGS:brandId "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection attempt detected in brandId parameter'"

# Alternative: Restrict access to the vulnerable file by IP
<Files "fetchSelectedBrand.php">
    Require ip 192.168.1.0/24
</Files>
