Underdist 3 Vulnerable VM Walkthrough




1) Initially I tried nmap to discover the open ports shown below.




2) Then I used Nikto and dirb for further enumeration.


3) Checking for port 80 gave me the following.

4) No clue left what to do next.
5) Then I tried view source and I saw the following.


6) Fetching the URL mentioned in the view-source gave me the following.

7) The url seem base64 encoding as == is present. I then decoded it and found the following.

8) Then I thought of encoding /etc/passwd in base64 format to launch LFI (Local file inclusion) attack.
I tried various payload such as /etc/passwd   ../../etc/passwd finally the following payload gave me /etc/passwd file on the browser.



9) Then I copied the /etc/passwd file in user.txt and created a userlist file for SSH and smtp bruteforce.

And yes, it is one the difficult mission you could ever face. Back in Dec 2014 I was really bored with the conventional vulnerability assessment thing, I wanted to do some more exploitation and some black hat stuff.

So I asked few question on some group in facebook regarding How can I learn more exploitation stuff. There was a guy with the name Mr.WhiteW0rm who have given me a brilliant answer and recommended me to do OSCP. That time I thought though I won't be able to do OSCP but at least I

Configure the victim: I have installed Minishare server 1.4.1 and it is listening for connections on port 80, as depicted below. Generate Sample script to crash: We will try to smash the stack by sending a buffer of 2000 A's with the help of the following script. #!/usr/share/python import socket,sys s=socket.socket(socket.AF_INET,socket.SOCK_STREAM) s.connect((sys.argv[1],80)) buff="GET " buff+="A"*2000 buff+=" HTTP/1.1\r\n\r\n" s.send(buff) s.close
