CVE-2025-1959: Gym Management System SQL Injection Flaw

CVE-2025-1959 Overview

A critical SQL injection vulnerability has been identified in Codezips Gym Management System version 1.0. The vulnerability exists in the /change_s_pwd.php file, where improper handling of the login_id and login_key parameters allows attackers to inject malicious SQL statements. This flaw enables remote attackers to manipulate database queries without authentication, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability remotely to extract sensitive information from the database, bypass authentication mechanisms, or modify critical data within the Gym Management System.

Technical Details for CVE-2025-1959

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the password change functionality within the Codezips Gym Management System. The vulnerable endpoint /change_s_pwd.php fails to properly sanitize user-supplied input in the login_id and login_key parameters before incorporating them into SQL queries.

The vulnerability allows unauthenticated remote attackers to inject arbitrary SQL commands through the affected parameters. Since no authentication is required to access the vulnerable endpoint, attackers can exploit this flaw directly over the network. Successful exploitation could result in unauthorized access to sensitive user data, administrative credentials, or complete database compromise.

Root Cause

The root cause of this vulnerability is insufficient input validation and the lack of parameterized queries (prepared statements) in the /change_s_pwd.php file. User-supplied data from the login_id and login_key parameters is directly concatenated into SQL queries without proper sanitization or escaping, allowing attackers to break out of the intended query structure and execute arbitrary SQL commands.

Attack Vector

The attack vector is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests to the /change_s_pwd.php endpoint with specially crafted values in the login_id or login_key parameters. These crafted values contain SQL metacharacters and statements that alter the logic of the backend SQL queries. The exploit has been publicly disclosed, increasing the risk of widespread exploitation attempts against unpatched systems.

Detection Methods for CVE-2025-1959

Indicators of Compromise

• Unusual SQL error messages or stack traces in web server logs originating from /change_s_pwd.php
• HTTP requests to /change_s_pwd.php containing SQL syntax such as single quotes, semicolons, UNION, SELECT, or OR statements in the login_id or login_key parameters
• Unexpected database queries or data access patterns that deviate from normal application behavior
• Signs of data exfiltration or unauthorized modifications to user accounts in the gym management database

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the /change_s_pwd.php endpoint
• Implement database activity monitoring to identify anomalous queries that may indicate SQL injection exploitation
• Configure intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging for the web application and database to capture all requests to /change_s_pwd.php
• Monitor for failed login attempts and password change requests that contain suspicious character patterns
• Set up alerts for database errors or exceptions that may indicate injection attempts
• Review access logs for requests from unexpected geographic locations or IP addresses targeting the vulnerable endpoint

How to Mitigate CVE-2025-1959

Immediate Actions Required

• Restrict network access to the Gym Management System to trusted IP addresses only until patching is possible
• Disable or remove the /change_s_pwd.php file if the password change functionality is not critical to operations
• Implement WAF rules to block requests containing SQL injection patterns targeting the affected parameters
• Conduct a database audit to identify any signs of prior exploitation or unauthorized data access

Patch Information

At the time of publication, no official vendor patch has been released for this vulnerability. Organizations using Codezips Gym Management System 1.0 should monitor the VulDB entry and GitHub CVE Documentation for updates on remediation guidance.

Workarounds

• Implement input validation on the login_id and login_key parameters to reject special characters and SQL keywords
• Use prepared statements with parameterized queries if modifying the source code is feasible
• Place the application behind a reverse proxy with SQL injection filtering capabilities
• Consider migrating to an alternative gym management solution that follows secure coding practices
