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.

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;
