可以看到有很多samba的信息，但这个先放放先从web入手。先看看web页面，不过首页和其他页面都没有什么交互和特殊的地方。
目录扫描
扫目录看得出来是wordpress，挨个访问几个目录都是空的，info.php就是一个phpinfo，去访问了phpadmin尝试了几个弱密码都没有登录进去。
wpscan枚举出两个用户admin和Admin，指定rockyou挂着跑一下看能不能抛出登录凭据。
但是访问/wordpress时，里面这个togie该是用户名。
共享文件泄露
web没有什么突破点，返回去看看smb有没有共享文件可查看，发现了有意思的share目录，且可以匿名进入，里面有几个txt。
都先下载下来，再接着浏览其他目录。在wordpress这个目录里面就重点关注了配置和设置页面，都下下来先。
接着翻到Backnode_files里面，有个很显眼的图片名像是base64，解码之后没什么特别的。
看看拿下来的这些文件，txt中有一弱口令12345，在配置文件里面有Mysql的凭据：Admin:TogieMYSQL12345^^

登录上去却发现当前这个用户根本无权操作数据库。
但是复用这个凭据可以登录web后台，那就利用后台来反弹shell，wp的话可以通过把
