🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch available. Consider implementing input validation and parameterized queries as workaround.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side validation to ensure ID parameter contains only expected characters (e.g., numeric values).
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns targeting the /ramonsys/course/controller.php endpoint.
🧯 If You Can't Patch
- Isolate the School Management System behind a reverse proxy with strict input filtering.
- Implement network segmentation to limit database access from the vulnerable application.
🔍 How to Verify
Check if Vulnerable:
Test the /ramonsys/course/controller.php endpoint with SQL injection payloads in the ID parameter (e.g., ' OR '1'='1).Check Version:
Check application version in admin panel or configuration files.Verify Fix Applied:
Verify that SQL injection attempts no longer succeed and that input validation is properly implemented.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed login attempts from single IP
- Requests with SQL keywords in ID parameter
Network Indicators:
- HTTP requests to /ramonsys/course/controller.php with suspicious ID values
- Unexpected database connection patterns
SIEM Query:
source="web_logs" AND uri="/ramonsys/course/controller.php" AND (id="*OR*" OR id="*UNION*" OR id="*SELECT*")
