Tunneling and Port Forwarding
socat
proxytunnel
proxychains
corkscrew
ssh [email protected] -t /bin/sh
For this technique, it is necessary to be able to upload a file to a webserver.
1. reGeorgFile upload to the server correct
Tunnel creation
python reGeorgSocksProxy.py -p 5555 -u "http://<ip>/admin/uploads/reGeorg.jsp"Proxychains config
proxychains nmap -F -sT 127.0.0.1
proxychains mysql -u root -p -h 127.0.0.1
proxychains ssh localhost
2. ABBTTS
Upload File
Config proxychains and create the tunnel
python abpttsclient.py -c tomcat_walkthrough/config.txt -u http://ip/abptts.jsp -f 127.0.0.1:22222/127.0.0.1:22Usagessh -p 22222 [email protected]
1. socatsocat TCP4-LISTEN:80,fork TCP4:REMOTE-HOST-IP-ADDRESS:80
2. iptablesiptables -I INPUT -p tcp -m tcp --dport 80 -j ACCEPTiptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination REMOTEADDR:80iptables -t nat -A POSTROUTING -j MASQUERADEiptables -I FORWARD -j ACCEPTiptables -P FORWARD ACCEPTsysctl net.ipv4.ip_forward=1
In this case this is going to be used to access Burp listening on a Windows NATed VM from other PCs in the same network as the Windows Host.
From the Windows Host machine (IP: 192.168.1.206)
Import-Module .\Invoke-SocksProxy.psm1
Invoke-SocksProxy -bindPort 1234
From other PC on the Windows Host machine network (IP: 192.168.1.69)
Configure
proxychains.conf: socks4 ip 1234
proxychains socat TCP-LISTEN:8081,fork,reuseaddr TCP:ip:8080
This command ahead makes Burp (which is listening on the NATed machine) accessible from ip on port 8081
Now, configure the Proxy in the browser:
All the traffic is logged on the NATed machine Burp.
Traffic forward over SSH without needing to
ssh -D <port>sshuttle -vr [email protected] 1X0.1X.0.0/16
