✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.campcodes.com/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing workarounds.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting the stud_no parameter
Input Validation Filter
allImplement server-side validation to reject non-alphanumeric characters in stud_no parameter
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls
- Implement database-level protections like stored procedures with parameterized inputs
🔍 How to Verify
Check if Vulnerable:
Test the login page with SQL injection payloads in the stud_no parameter (e.g., ' OR '1'='1)Check Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and return proper error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in login requests
- Multiple failed login attempts with SQL characters
- Database error messages in application logs
Network Indicators:
- HTTP POST requests to /index.php containing SQL keywords in stud_no parameter
- Unusual database connection patterns
SIEM Query:
source="web_logs" AND uri="/index.php" AND (stud_no CONTAINS "' OR" OR stud_no CONTAINS "UNION" OR stud_no CONTAINS "SELECT")
