🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
1. Check vendor website for updates. 2. If no patch available, implement workarounds. 3. Consider replacing with supported software.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to reject SQL special characters in Username parameter
Modify add-teacher.php to include: $username = preg_replace('/[^a-zA-Z0-9]/', '', $_POST['Username']);
Web Application Firewall
allDeploy WAF with SQL injection rules to block malicious requests
🧯 If You Can't Patch
- Block external access to /add-teacher.php using firewall rules or .htaccess
- Implement network segmentation to isolate vulnerable system from sensitive data
🔍 How to Verify
Check if Vulnerable:
Test /add-teacher.php with SQL injection payloads in Username parameter (e.g., ' OR '1'='1)Check Version:
Check software documentation or admin panel for version informationVerify Fix Applied:
Verify SQL injection attempts no longer succeed and return appropriate error messages📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Unusual database queries from web application
- Multiple failed login attempts with SQL characters
Network Indicators:
- HTTP POST requests to /add-teacher.php containing SQL keywords
- Unusual database port traffic from web server
SIEM Query:
source="web_logs" AND uri="/add-teacher.php" AND (payload="UNION" OR payload="SELECT" OR payload="OR '1'='1")
