Exploit details are publicly available and SQL injection is a well-understood attack vector with many automated tools available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd parameterized queries or proper input validation to the ID parameter in manage_register.php
Modify PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM table WHERE id = ?'); $stmt->bind_param('i', $id);
Web Application Firewall Rules
allImplement WAF rules to block SQL injection patterns targeting the vulnerable endpoint
Add WAF rule: Block requests containing SQL keywords (UNION, SELECT, INSERT, etc.) in the ID parameter
🧯 If You Can't Patch
- Restrict access to /admin/manage_register.php using IP whitelisting or authentication
- Implement database-level protections: Use least privilege database accounts, enable query logging
🔍 How to Verify
Check if Vulnerable:
Test the /admin/manage_register.php endpoint with SQL injection payloads like: ?id=1' OR '1'='1Check Version:
Check software version in admin panel or readme filesVerify Fix Applied:
Verify that SQL injection payloads no longer work and return proper error handling📡 Detection & Monitoring
Log Indicators:
