发现好多目录文件，最后发现http://192.168.177.199/store/database/有两个有趣的文件

有sql文件，下载下来看看。

发现了admin账号和加密后的密码

看样子应该是md5，去网站破解一下看看

没想到密码如此简单，admin。去登录看看。

其他地方登录不了这里可以登录

http://192.168.177.199/store/admin_book.php

添加书籍部分有上传功能，出版商必须是已经存在的，上传shell试试

getshell

前台看元素，src找到shell地址，http://192.168.177.199/store/bootstrap/img/cmd.php

shell要POST的，GET的不好使，我也不知道为什么。

蚁剑链接webshell

提权

在/home/tony目录下发现ssh密码

登录ssh

sudo提权

sudo -l

我这里直接使用AutoSUID提权脚本提权

获得flag
