CVE-2025-4307: Art Gallery Management System SQLi Flaw

CVE-2025-4307 Overview

A critical SQL injection vulnerability has been discovered in PHPGurukul Art Gallery Management System version 1.1. The vulnerability exists in the /admin/add-art-medium.php file where the artmed parameter is not properly sanitized before being used in SQL queries. This flaw allows remote attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive information from the database, modify or delete data, and potentially gain unauthorized administrative access to the Art Gallery Management System.

Affected Products

• PHPGurukul Art Gallery Management System 1.1
• Web applications using vulnerable /admin/add-art-medium.php endpoint

Technical Details for CVE-2025-4307

Vulnerability Analysis

This SQL injection vulnerability affects the administrative interface of PHPGurukul Art Gallery Management System. The vulnerability is accessible over the network without requiring authentication or user interaction, making it particularly dangerous for publicly accessible installations. The flaw allows attackers to inject malicious SQL commands through the artmed parameter in the art medium management functionality.

The vulnerability enables attackers to bypass application logic and directly interact with the underlying database. Successful exploitation could result in unauthorized access to stored data including user credentials, art gallery records, and other sensitive information managed by the system.

Root Cause

The root cause of this vulnerability is improper input validation and sanitization of user-supplied data in the /admin/add-art-medium.php file. The artmed parameter accepts user input that is directly incorporated into SQL queries without proper escaping, parameterization, or prepared statements. This represents a classic injection vulnerability (CWE-74) where untrusted data is used to construct database commands.

Attack Vector

The attack can be launched remotely over the network. An attacker can craft malicious HTTP requests containing SQL injection payloads in the artmed parameter. The vulnerable endpoint processes these requests and executes the injected SQL code against the database.

The exploitation technique involves submitting specially crafted input through the art medium management form or directly via HTTP requests to the vulnerable endpoint. Standard SQL injection techniques such as UNION-based injection, blind injection, or time-based injection methods may be applicable depending on the specific implementation and database configuration.

Detection Methods for CVE-2025-4307

Indicators of Compromise

• Unusual or malformed requests to /admin/add-art-medium.php containing SQL syntax
• Database error messages in application logs indicating query failures
• Unexpected database query patterns or execution of administrative commands
• Access logs showing repeated attempts to the vulnerable endpoint with varying payloads

Detection Strategies

• Monitor web application logs for requests containing SQL keywords (SELECT, UNION, INSERT, DROP, etc.) in the artmed parameter
• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns
• Deploy database activity monitoring to identify anomalous query patterns
• Review authentication logs for unauthorized administrative access attempts

Monitoring Recommendations

• Enable detailed logging for the /admin/ directory and associated PHP files
• Configure alerts for database errors that may indicate injection attempts
• Monitor for unusual data exfiltration patterns from the database server
• Implement real-time monitoring of HTTP requests to administrative endpoints

How to Mitigate CVE-2025-4307

Immediate Actions Required

• Restrict network access to the administrative interface (/admin/) to trusted IP addresses only
• Implement input validation to reject requests containing SQL injection patterns
• Consider taking the application offline until a patch is available or mitigations are in place
• Review database logs for evidence of prior exploitation

Patch Information

No official vendor patch has been confirmed at this time. Organizations should monitor the PHP Gurukul website for security updates. Additional technical details and discussion are available at the GitHub Issue Discussion and VulDB #307410.

Workarounds

• Implement prepared statements or parameterized queries in the affected PHP file to prevent SQL injection
• Deploy a Web Application Firewall (WAF) with SQL injection detection rules in front of the application
• Restrict access to administrative endpoints using IP whitelisting or VPN requirements
• Apply principle of least privilege to database accounts used by the application to limit potential damage from successful exploitation

# Example: Restrict admin access via .htaccess
# Add to /admin/.htaccess file
<Files "add-art-medium.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Files>
