How to fix
|
|
----------
|
|
One of the method's to fix and secure such Auth Bypass flaw's, is to use the php function mysql_real_escape_string.
|
|
It causes that every of this characters \x00, \n, \r, \, '
|
|
get's replaced with a simple Backslash „/“, so the attackers commands become useless.
|
|
|
|
Example:
|
|
|
|
if (isset($_POST['submit'])){
|
|
$lga_id=mysql_real_escape_string($_POST['lgaid']);
|
|
$pw=mysql_real_escape_string($_POST['pwd']);
|
|
$_SESSION['username'] = $lga_id;
|
|
|
|
|
|
$sql=mysql_query("SELECT * FROM admin WHERE lga_id='$lga_id' AND password='$pw' ");
