CVE-2025-2643: Art Gallery Management System SQLi Flaw

CVE-2025-2643 Overview

A critical SQL Injection vulnerability has been identified in PHPGurukul Art Gallery Management System version 1.0. This vulnerability exists in the /admin/edit-art-type-detail.php file, where the arttype parameter is susceptible to SQL injection attacks. The flaw allows remote attackers to manipulate database queries by injecting malicious SQL code through user-supplied input, potentially compromising the confidentiality, integrity, and availability of the underlying database.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database records, or potentially gain unauthorized access to the Art Gallery Management System's backend database without authentication.

Affected Products

• PHPGurukul Art Gallery Management System 1.0
• Web applications using the vulnerable /admin/edit-art-type-detail.php endpoint
• Systems with network-accessible instances of the Art Gallery Management System

Technical Details for CVE-2025-2643

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) occurs in the administrative interface of PHPGurukul Art Gallery Management System. The vulnerable endpoint /admin/edit-art-type-detail.php?editid=1 fails to properly sanitize the arttype parameter before incorporating it into SQL queries. This injection flaw (CWE-74) allows attackers to manipulate database operations by crafting malicious input that escapes the intended query context.

The vulnerability is network-accessible, meaning attackers can exploit it remotely without requiring local system access. No user interaction is needed for exploitation, and the attack complexity is low, making this an easily exploitable flaw in real-world scenarios.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries or prepared statements in the PHP code handling the arttype parameter. When user-supplied data is directly concatenated into SQL queries without proper sanitization or escaping, attackers can inject arbitrary SQL commands that the database will execute with the same privileges as the application.

Attack Vector

The attack is initiated remotely via HTTP requests to the /admin/edit-art-type-detail.php endpoint. An attacker crafts a malicious request containing SQL injection payloads in the arttype parameter. When the vulnerable application processes this request, the injected SQL code is executed against the backend database, potentially allowing the attacker to:

• Extract sensitive information from the database (data exfiltration)
• Modify or delete existing database records
• Bypass authentication mechanisms
• Escalate privileges within the application
• Potentially achieve command execution on the underlying system depending on database configuration

The vulnerability has been publicly disclosed, and technical details are available through the GitHub Issue Discussion and VulDB #300658, increasing the likelihood of exploitation attempts in the wild.

Detection Methods for CVE-2025-2643

Indicators of Compromise

• Unusual SQL error messages appearing in application logs from the /admin/edit-art-type-detail.php endpoint
• Database query logs showing unexpected or malformed queries containing SQL keywords like UNION, SELECT, INSERT, UPDATE, DELETE, or comment sequences (--, /*)
• Anomalous access patterns to administrative endpoints from unfamiliar IP addresses
• Evidence of data exfiltration or unauthorized database modifications

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the arttype parameter
• Monitor web server access logs for requests containing SQL injection payloads directed at /admin/edit-art-type-detail.php
• Deploy database activity monitoring to identify suspicious queries or unauthorized data access
• Configure intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging on web servers and database systems to capture all requests to the vulnerable endpoint
• Set up alerts for database errors that may indicate SQL injection attempts
• Monitor for bulk data extraction patterns that could indicate successful exploitation
• Regularly audit database access logs for anomalous query patterns

How to Mitigate CVE-2025-2643

Immediate Actions Required

• Restrict network access to the administrative interface /admin/ directory using IP whitelisting or VPN requirements
• Implement WAF rules to filter SQL injection patterns on the affected endpoint
• Consider temporarily disabling or removing the /admin/edit-art-type-detail.php functionality until a patch is available
• Review and audit database permissions to minimize the potential impact of SQL injection attacks

Patch Information

As of the last update on 2025-04-02, no official vendor patch has been released for this vulnerability. Organizations using PHPGurukul Art Gallery Management System should monitor the PHPGurukul website for security updates. For detailed vulnerability tracking information, refer to VulDB CTI ID #300658.

Workarounds

• Apply input validation to the arttype parameter by implementing server-side sanitization that strips or escapes special SQL characters
• Migrate the vulnerable code to use prepared statements (PDO or MySQLi with parameterized queries) to prevent SQL injection
• Deploy a reverse proxy or WAF with SQL injection protection rules in front of the application
• Restrict database user privileges to minimum required permissions (principle of least privilege) to limit potential damage from successful exploitation

# Example Apache .htaccess configuration to restrict admin access
<Directory "/var/www/html/admin">
    # Restrict access to specific IP addresses
    Require ip 192.168.1.0/24
    Require ip 10.0.0.0/8
    
    # Deny all other access
    Require all denied
</Directory>
