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.

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
