CVE-2024-6041: Gym Management System SQL Injection Flaw

CVE-2024-6041 Overview

CVE-2024-6041 is a SQL injection vulnerability in itsourcecode Gym Management System 1.0. The flaw resides in the manage_user.php file, where the id parameter is not properly sanitized before being used in a database query. Attackers can manipulate the id argument to inject arbitrary SQL statements. The vulnerability is remotely exploitable and requires low-privileged authentication. The exploit has been publicly disclosed, increasing the risk of opportunistic attacks against exposed instances. The issue is tracked as VDB-268765 and mapped to CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).

Critical Impact
Remote authenticated attackers can inject SQL through the id parameter of manage_user.php, exposing user records and enabling unauthorized data modification.

Technical Details for CVE-2024-6041

Vulnerability Analysis

The vulnerability affects the user management workflow of the Gym Management System. The manage_user.php script accepts an id request parameter and passes the value into a backend SQL query without applying parameterized statements or input sanitization. Because the value is concatenated directly into the SQL string, an attacker can break out of the intended query context and append arbitrary SQL clauses.

Exploitation requires network access to the application and low-privileged credentials. No user interaction is needed. The impact spans confidentiality, integrity, and availability of the underlying database, limited by the privileges granted to the application's database user. Public disclosure of the exploit details on GitHub and VulDB lowers the barrier for weaponization.

Root Cause

The root cause is improper neutralization of special elements used in an SQL command [CWE-89]. The application does not validate or escape the id parameter before including it in a query. There is no evidence of prepared statements or a database access layer that enforces type binding on the parameter.

Attack Vector

An authenticated attacker sends a crafted HTTP request to manage_user.php with a malicious payload appended to the id parameter. Payloads typically use SQL operators such as UNION SELECT, boolean-based conditions, or time-based delays to enumerate schema information, extract records, or modify data. Because the request is issued over the network, the vulnerability can be exploited from any host that can reach the web application.

See the public disclosure at the GitHub issue and VulDB entry #268765 for additional technical details.

Detection Methods for CVE-2024-6041

Indicators of Compromise

HTTP requests to manage_user.php with id parameter values containing SQL keywords such as UNION, SELECT, SLEEP, --, or /*.
Unusual database errors returned to the client from pages that reference the user management workflow.
Sudden spikes in query latency on the backend database correlating with requests to manage_user.php, indicating time-based SQL injection.
Unexpected read or write access to the users table or authentication-related tables outside of normal administrative activity.

Detection Strategies

Deploy web application firewall (WAF) signatures that flag SQL metacharacters in the id parameter of manage_user.php.
Enable database query logging and alert on queries against user tables that contain concatenated user-supplied values or tautologies like OR 1=1.
Correlate authenticated session activity with high-volume requests targeting a single endpoint to detect enumeration attempts.

Monitoring Recommendations

Forward web server access logs and database audit logs to a centralized analytics platform for continuous review.
Baseline the normal parameter shape of id (numeric integers) and alert on non-numeric input.
Monitor for outbound data transfer anomalies from the database host that may indicate mass extraction.

How to Mitigate CVE-2024-6041

Immediate Actions Required

Restrict network exposure of the Gym Management System to trusted networks or place it behind an authenticated VPN until remediated.
Rotate credentials for any accounts used to authenticate to the application and for the database service account.
Review web and database logs for prior exploitation activity targeting manage_user.php.
Deploy WAF rules that block SQL injection payloads in the id parameter.

Patch Information

As of the last NVD update, no official vendor patch has been published for itsourcecode Gym Management System 1.0. Organizations should monitor the vendor and the VulDB advisory for remediation guidance and apply updates when they become available.

Workarounds

Modify manage_user.php to use parameterized queries or prepared statements with bound parameters instead of string concatenation.
Enforce server-side input validation that constrains the id parameter to a positive integer before use.
Apply the principle of least privilege to the database account used by the application, limiting it to only the tables and operations required.
Disable verbose database error messages in production to reduce information leakage that assists injection attacks.
