Threat: Loki RAT (Relapse)
Vulnerability: SQL Injection
Description: The LokiRAT WebUI panel for LokiRAT_Relapse.exe runs on PHP and MySQL and is used to control infected hosts through a central server.
The backend server side code "admin.php" does not use any secure coding practices nor does it sanitize or filter user input when constructing MySQL statements. Â
Loki admin.php takes four parameter's pass, command, id and type. There's an auth check using $_GET['pass'] against the clear-text password "test" in settings.php.
The $_GET['id'] parameter is used directly in SELECT * FROM vircom WHERE id='$id' statement used in mysql_query() func, making it vulnerable to post-auth SQL Injection.
Authenticated users or third-party attackers who can guess the password can easily dump all databases, tables and contents including the MySQL database schema.
admin.php snippet:
if ($_GET['pass'] == $password) {
$command = $_REQUEST['command'];
$id = $_GET['id'];
$type = $_GET['type'];
 ....
 case "response":
   $query = mysql_query("SELECT * FROM vircom WHERE id='$id'");
   $row = mysql_fetch_array($query);
   echo $row['retCommandNum'] . "{-}" . $row['retCommand'] . "{-}" . $row['lastUpdate'] . "{-}" . $row['updateInterval'];
   break;
