🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
No official patch available. Consider implementing input validation and parameterized queries in the source code.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns targeting the /ajax.php endpoint.
Input Validation Filter
allAdd server-side input validation to reject SQL special characters in the Username parameter.
🧯 If You Can't Patch
- Isolate the application behind a reverse proxy with strict input filtering
- Implement network segmentation to limit database access from the application server
🔍 How to Verify
Check if Vulnerable:
Test the /ajax.php?action=login endpoint with SQL injection payloads in the Username parameter and observe database errors or unexpected responses.Check Version:
Check the application version in the admin panel or source code files.Verify Fix Applied:
Verify that SQL injection attempts no longer produce database errors or allow unauthorized access.📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in application logs
- Multiple failed login attempts with SQL special characters
- Unusual database queries from the application server
Network Indicators:
- HTTP POST requests to /ajax.php containing SQL keywords like UNION, SELECT, OR 1=1
SIEM Query:
source="web_logs" AND uri="/ajax.php" AND (query="*UNION*" OR query="*SELECT*" OR query="*OR 1=1*")
