What is XXE Vulnerability? An XML External Entity attack is a type of attack against an application that parses
In this weekend, I will try to write a walkthrough to the VulnHub Bulldog 1. You can download this CTF VM on VulnHub’s website. First, I need to find some open port on the target machine.
nmap -p- 192.168.56.101
Starting Nmap 7.60 ( https://nmap.org ) at 2017-11-04 11:35 WIB
Nmap scan report for 192.168.56.101
Host is up (0.0026s latency).
Not shown: 65532 closed ports
PORT STATE SERVICE
23/tcp open telnet
80/tcp open http
8080/tcp open http-proxy
Nmap done: 1 IP address (1 host up) scanned in 0.81 seconds
I got 3 open ports on the target machine. Now let’s find out what services are running on
Fiddler is a free web debugging proxy which logs all HTTP(s) traffic between your computer and the Internet.

Lets continue the last article since i was busy with my real life. From the last article i successfully get into the server from SSH service. Now lets enumerate the network inside the server based on this network diagram. First, lets check if Nmap already installed on the server:
e.lindsey@tl10-ssh:~$ nmap -version
Nmap version 6.00 ( http://nmap.org )
Compiled with: liblua-5.1.5 openssl-1.0.1e libpcre-8.30 libpcap-1.3.0 nmap-libdnet-1.12 ipv6
Great!! lets mapping the network.
