看来用户名已经找到了，加密后的密码也已经找到，接下去是要破解密码，再修改一下代码，用utf-8编码后再做hash：
再次执行，这次没有出错，但是并没有爆破出来密码：

至此不知道往下如何办了，看了其他人的做法，这个字典文件是用于FTP的，而且猜测hacksudo这个用户名也同时是FTP的用户名，难怪一直不能破解成功！

在http://192.168.56.210/index1.html提到了凯撒密码，所以这里用在线网站解密（位移是3位）(https://www.qqxiuzi.cn/bianma/kaisamima.php)
解密后得到：
wwww.localhost/fog Username=fog:password=hacksudoISRO，用这个密码再登录一下CMS
可以成功登录，然后试一下远程执行漏洞代码，执行失败。
还是看一下有无可以上传shell.php入口，发现有过滤，尝试扩展名.phtml,发现可以成功上传
访问该页面：
成功拿到了shell
