CVE-2025-0881: Gym Management System SQLi Vulnerability

CVE-2025-0881 Overview

A critical SQL Injection vulnerability has been identified in Codezips Gym Management System version 1.0. The vulnerability exists in the /dashboard/admin/saveroutine.php file, where improper handling of the rname parameter allows attackers to inject malicious SQL commands. This flaw can be exploited remotely by authenticated attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers with low privileges can exploit this SQL injection vulnerability to bypass authentication, extract sensitive data from the database, modify records, or potentially compromise the underlying server through database exploitation techniques.

Affected Products

• Codezips Gym Management System 1.0
• codezips:gym_management_system component

Technical Details for CVE-2025-0881

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) stems from insufficient input validation in the Codezips Gym Management System's routine management functionality. The affected endpoint /dashboard/admin/saveroutine.php accepts user-supplied input through the rname parameter without proper sanitization or parameterized queries. When a malicious payload is crafted and submitted through this parameter, it gets directly concatenated into SQL queries executed against the backend database.

The vulnerability is classified under both CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating the application fails to properly neutralize user input before incorporating it into database operations.

Root Cause

The root cause of this vulnerability is the lack of input sanitization and the use of dynamic SQL query construction. The application directly incorporates user-supplied data from the rname parameter into SQL statements without employing prepared statements, parameterized queries, or input validation. This allows specially crafted input containing SQL metacharacters to alter the intended query logic.

Attack Vector

The attack can be launched remotely over the network. An attacker with low-level privileges can craft malicious HTTP requests targeting the /dashboard/admin/saveroutine.php endpoint. By manipulating the rname parameter with SQL injection payloads, attackers can:

1. Extract sensitive information from the database including user credentials and personal data
2. Modify or delete database records
3. Bypass authentication mechanisms
4. Potentially escalate to remote code execution if database features like xp_cmdshell (SQL Server) or INTO OUTFILE (MySQL) are available

The vulnerability has been publicly disclosed, and exploit details are available through the GitHub Issue and VulDB entry #294126. Attackers can inject SQL commands through the rname parameter by appending SQL syntax such as single quotes, UNION statements, or boolean-based injection payloads to manipulate the underlying database queries.

Detection Methods for CVE-2025-0881

Indicators of Compromise

• Unusual HTTP requests to /dashboard/admin/saveroutine.php containing SQL keywords such as UNION, SELECT, DROP, INSERT, or DELETE in the rname parameter
• Database error messages in application logs indicating malformed SQL syntax
• Unexpected database queries or data extraction patterns in database audit logs
• Authentication bypass attempts or unauthorized access to admin functionality

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP parameters targeting the Gym Management System
• Implement database activity monitoring to detect anomalous queries, including those with UNION SELECT statements, stacked queries, or time-based blind injection attempts
• Configure intrusion detection systems (IDS) to alert on suspicious traffic patterns targeting /dashboard/admin/saveroutine.php
• Review web server access logs for requests containing URL-encoded SQL metacharacters (%27, %22, %3B)

Monitoring Recommendations

• Enable verbose logging on the web application to capture all requests to the /dashboard/admin/ directory
• Configure database audit logging to track all queries executed by the application's database user
• Set up alerts for multiple failed authentication attempts or unusual data access patterns
• Monitor for outbound connections from the database server which could indicate successful exploitation and data exfiltration

How to Mitigate CVE-2025-0881

Immediate Actions Required

• Restrict access to the Codezips Gym Management System to trusted networks or IP addresses only
• Implement network-level access controls to limit exposure of the administrative interface
• Deploy a Web Application Firewall (WAF) with SQL injection detection rules in front of the application
• Consider temporarily disabling the routine management functionality if possible until a patch is available
• Back up the database and audit for any signs of compromise

Patch Information

At the time of publication, no official patch has been released by Codezips for this vulnerability. Organizations using this software should monitor the vendor's communication channels for security updates. In the meantime, implementing the workarounds and mitigation strategies outlined below is strongly recommended.

For additional technical details, refer to the VulDB submission #489192 and VulDB CTI entry.

Workarounds

• Implement input validation on the server-side to sanitize the rname parameter, rejecting any input containing SQL metacharacters
• If access to source code is available, modify the application to use prepared statements or parameterized queries for all database operations
• Deploy a reverse proxy with ModSecurity or similar WAF capabilities configured with OWASP Core Rule Set (CRS) to filter malicious requests
• Restrict database user permissions to the minimum required, preventing dangerous operations like file writes or command execution
