Description:
------------
---
From manual page: http://www.php.net/function.strcasecmp#refsect1-
function.strcasecmp-returnvalues
---
Function strcasecmp will return NULL if it gets an array. Now it seems that
function will return only an integer, and this
assumption can be a security risk, like in the example bellow.
Test script:
---------------
<?php
$pass = isset($_GET['pass'])?$_GET['pass']:'';
// Query /?pass=[] will authorize user
if ( strcasecmp( $pass, '123456' ) == 0 )
{
echo 'You successfully logged in.';
}
