🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement parameterized queries and input validation for the uname parameter
Modify /cussignup.php to use prepared statements: $stmt = $conn->prepare('SELECT * FROM users WHERE username = ?'); $stmt->bind_param('s', $uname);
Web Application Firewall Rules
allBlock SQL injection patterns targeting /cussignup.php
Add WAF rule: SecRule REQUEST_URI "@streq /cussignup.php" "id:1001,phase:2,deny,msg:'SQLi attempt on cussignup.php'"
🧯 If You Can't Patch
- Restrict access to /cussignup.php using network ACLs or authentication
- Implement database user with minimal privileges (read-only if possible)
🔍 How to Verify
Check if Vulnerable:
Test the /cussignup.php endpoint with SQL injection payloads like: uname=admin' OR '1'='1Check Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer work and that parameterized queries are implemented📡 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 requests to /cussignup.php containing SQL keywords (UNION, SELECT, INSERT)
- Abnormal database traffic patterns
SIEM Query:
source="web_logs" AND uri="/cussignup.php" AND (query CONTAINS "' OR" OR query CONTAINS "UNION" OR query CONTAINS "SELECT *")
