🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize txtLogin parameter before SQL processing
Modify /admin/index.php to add: $txtLogin = mysqli_real_escape_string($connection, $_POST['txtLogin']);
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns
Add ModSecurity rule: SecRule ARGS:txtLogin "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Isolate the web store application in a segmented network zone with strict firewall rules
- Implement strong authentication (MFA) for admin access and monitor for suspicious login attempts
