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.
