CVE-2025-15410: Online Guitar Store SQL Injection Flaw

CVE-2025-15410 Overview

A SQL Injection vulnerability has been identified in code-projects Online Guitar Store version 1.0. The vulnerability exists in the /login.php file, where the L_email parameter is susceptible to SQL injection attacks due to improper input validation. This flaw allows remote attackers to manipulate database queries, potentially leading to unauthorized data access, data modification, or authentication bypass.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive user data, or modify database contents without authorization.

Affected Products

• Anisha Online Guitar Store 1.0
• code-projects Online Guitar Store 1.0

Technical Details for CVE-2025-15410

Vulnerability Analysis

This 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). The vulnerability exists in the login functionality of the Online Guitar Store application, specifically within the /login.php endpoint.

The L_email parameter accepts user-supplied input that is directly incorporated into SQL queries without proper sanitization or parameterized query usage. This allows attackers to inject arbitrary SQL commands that are executed by the database server, potentially compromising the entire application's data integrity and confidentiality.

Root Cause

The root cause of this vulnerability is the failure to properly sanitize user input before incorporating it into SQL queries. The application directly concatenates the L_email parameter value into SQL statements without using prepared statements or parameterized queries. This classic SQL injection pattern allows malicious input to alter the intended SQL query structure.

Attack Vector

The attack can be initiated remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests to the /login.php endpoint with specially crafted SQL injection payloads in the L_email parameter. Common attack techniques include:

• Authentication bypass using payloads like ' OR '1'='1' --
• Union-based SQL injection to extract data from other tables
• Time-based blind SQL injection for data exfiltration
• Error-based injection to enumerate database structure

The vulnerability has been publicly documented, with technical details available in the GitHub Issue Tracker and VulDB entry #339330.

Detection Methods for CVE-2025-15410

Indicators of Compromise

• Unusual database query patterns or errors in web server logs related to /login.php
• Multiple failed login attempts followed by successful authentication from the same IP
• HTTP requests to /login.php containing SQL syntax characters (single quotes, double dashes, semicolons) in the L_email parameter
• Database audit logs showing unexpected SELECT, UNION, or information_schema queries

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the L_email parameter
• Implement intrusion detection signatures for common SQL injection payloads targeting login forms
• Monitor HTTP request logs for suspicious characters and SQL keywords in authentication parameters
• Enable database query logging and alert on anomalous query patterns from the web application

Monitoring Recommendations

• Enable verbose logging on the web server to capture full request parameters for /login.php
• Configure database audit logging to track all queries executed against user authentication tables
• Set up alerts for error conditions related to SQL syntax errors originating from the login endpoint
• Monitor for data exfiltration patterns such as large response sizes from login endpoints

How to Mitigate CVE-2025-15410

Immediate Actions Required

• Immediately implement input validation and sanitization for the L_email parameter in /login.php
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules as a temporary mitigation
• Consider temporarily disabling the affected login functionality if a secure alternative exists
• Review application logs for evidence of prior exploitation attempts

Patch Information

No official vendor patch is currently available for this vulnerability. Organizations using code-projects Online Guitar Store 1.0 should implement the workarounds listed below and monitor the Code Projects website for security updates. Given the publicly available nature of the vulnerability details, immediate action is strongly recommended.

Workarounds

• Replace direct SQL query concatenation with prepared statements or parameterized queries in /login.php
• Implement strict input validation for the L_email parameter, allowing only valid email format characters
• Deploy a WAF or reverse proxy with SQL injection filtering capabilities in front of the application
• Implement database user privilege restrictions to limit the impact of successful SQL injection attacks
