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 登录 wordpress 后，我们会看到一个草稿帖子，发现有密码：n0t1n@w0rdl1st!
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。
