CVE-2025-4309
📋 TL;DR
This critical SQL injection vulnerability in PHPGurukul Art Gallery Management System 1.1 allows attackers to manipulate database queries through the 'arttype' parameter in the /admin/add-art-type.php file. Attackers can potentially read, modify, or delete database content, and in worst cases gain administrative access. Organizations using this specific version of the software are affected.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, system takeover, and potential lateral movement to other systems
Likely Case
Database information disclosure, data manipulation, and potential administrative account takeover
If Mitigated
Limited impact with proper input validation and database permissions in place
🎯 Exploit Status
Exploit requires admin access; SQL injection is well-understood and easily weaponized
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://phpgurukul.com/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd parameterized queries and input validation to the add-art-type.php file
Modify PHP code to use prepared statements: $stmt = $conn->prepare('INSERT INTO art_types (arttype) VALUES (?)'); $stmt->bind_param('s', $arttype); $stmt->execute();
Access Restriction
allRestrict access to the vulnerable admin interface
Add .htaccess rules: Order Deny,Allow
Deny from all
Allow from 192.168.1.0/24
Implement IP whitelisting in PHP
🧯 If You Can't Patch
- Implement WAF rules to block SQL injection patterns targeting the /admin/add-art-type.php endpoint
- Isolate the system from internet access and restrict internal access to authorized users only
🔍 How to Verify
Check if Vulnerable:
Test the /admin/add-art-type.php endpoint with SQL injection payloads in the arttype parameterCheck Version:
Check version in system configuration files or admin panelVerify Fix Applied:
Test with SQL injection payloads after implementing parameterized queries; payloads should be rejected or sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts to admin panel
- Unexpected database operations from web server IP
Network Indicators:
- HTTP POST requests to /admin/add-art-type.php with SQL keywords in parameters
- Unusual outbound database connections from web server
SIEM Query:
source="web_logs" AND uri="/admin/add-art-type.php" AND (param="arttype" AND value MATCHES "(?i)(union|select|insert|update|delete|drop|--|#|/*)")
