CVE-2025-9596: Sports Management System SQL Injection Flaw

CVE-2025-9596 Overview

A SQL injection vulnerability has been identified in itsourcecode Sports Management System version 1.0. This security flaw affects the /login.php file, where manipulation of the User argument enables attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially compromising the underlying database and sensitive user information.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive data, modify database contents, or potentially gain unauthorized access to the underlying system.

Affected Products

• Angeljudesuarez Sports Management System 1.0
• itsourcecode Sports Management System 1.0

Technical Details for CVE-2025-9596

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) resides in the authentication mechanism of the Sports Management System. The /login.php endpoint fails to properly sanitize user-supplied input before incorporating it into SQL queries. When processing the User parameter, the application directly concatenates user input into database queries without adequate input validation or parameterized queries.

The exploitation of this vulnerability requires no prior authentication or user interaction. An attacker can craft malicious SQL statements through the login form to manipulate database operations. The exploit has been publicly disclosed according to the vulnerability report, increasing the risk of active exploitation in the wild.

Root Cause

The root cause of this vulnerability is improper input validation and the lack of parameterized queries in the login functionality. The application constructs SQL queries using direct string concatenation with user-controlled input from the User parameter. This allows attackers to inject arbitrary SQL syntax that gets executed by the database engine with the privileges of the application's database user.

Attack Vector

The attack vector is network-based, allowing remote exploitation without authentication. An attacker can target the /login.php endpoint by submitting specially crafted payloads in the User field. The vulnerability requires low attack complexity and no user interaction.

The exploitation typically involves:

1. Accessing the login page at /login.php
2. Injecting SQL syntax through the User input field
3. Manipulating the authentication query to bypass login controls or extract database information
4. Leveraging successful injection to enumerate database tables, extract credentials, or modify data

Detection Methods for CVE-2025-9596

Indicators of Compromise

• Unusual login attempts containing SQL syntax characters such as single quotes ('), double dashes (--), or UNION statements in web server logs
• Database query errors appearing in application logs indicating malformed SQL
• Unexpected database queries or access patterns originating from the web application
• Authentication bypass events where users gain access without valid credentials

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the User parameter
• Monitor web server access logs for requests to /login.php containing suspicious SQL metacharacters
• Configure database audit logging to detect unusual query patterns or unauthorized data access
• Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging on the Sports Management System web application
• Monitor authentication events for anomalous patterns or repeated failed attempts with SQL-like payloads
• Set up alerts for database errors that may indicate injection attempts
• Review access logs regularly for evidence of reconnaissance or exploitation activity

How to Mitigate CVE-2025-9596

Immediate Actions Required

• Restrict network access to the Sports Management System to trusted IP addresses only
• Implement a Web Application Firewall with SQL injection protection rules
• Review and audit all authentication logs for signs of previous exploitation
• Consider taking the application offline until a proper fix can be implemented

Patch Information

No official vendor patch has been released for this vulnerability at the time of publication. The affected software is itsourcecode Sports Management System 1.0, developed by angeljudesuarez. Organizations should monitor the IT Source Code website and VulDB for updates regarding security patches.

Workarounds

• Deploy a Web Application Firewall (WAF) configured to block SQL injection attacks targeting the login endpoint
• Implement input validation at the network edge to filter malicious characters before they reach the application
• Restrict database user privileges to minimize the impact of successful SQL injection exploitation
• If source code access is available, modify /login.php to use parameterized queries or prepared statements
