Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement parameterized queries or input validation for the ID parameter in /subject/index.php
Modify PHP code to use prepared statements: $stmt = $pdo->prepare('SELECT * FROM subjects WHERE id = ?'); $stmt->execute([$id]);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting the /subject/index.php endpoint
Add WAF rule: Block requests to /subject/index.php with SQL injection patterns in parameters
🧯 If You Can't Patch
- Isolate the system from internet access and restrict to internal network only
- Implement strict network segmentation and monitor all database access attempts
🔍 How to Verify
Check if Vulnerable:
Test the /subject/index.php endpoint with SQL injection payloads like: /subject/index.php?id=1' OR '1'='1Check Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer return database errors or unexpected data📡 Detection & Monitoring
