HACKTHEBOX-POSTMAN-WALKTHROUGH


Index:

1. finding the ports.
2. exploiting Redis.
3. cracking RSA key.
4. getting user.
5. getting root.


1. Starting with the portscan with Nmap. I found many ports open, but the scan does not show all the ports so I scanned all the ports. And I found an interesting port named Redis.

2. For Redis exploitation, either you can follow the article written in kali-Linux-cookbook or just click the link below.


3. After getting the shell as Redis, I found id-rsa.bak in /opt, transfer the encrypted ssh key to my computer.

4. Then I used the tool ‘ssh2john.py’ to take the hash of the private key and then brute-force the key to get the password.

   python ssh2john.py key doitnow.

cracking hash
5. Then I tried ssh login but it denied so I again logged in as Redis and used su matt with password computer2008 and I got the mat user.


owned user
5 For root. I enumerate the port 10000 and I found a login page of Webmin 1.910, logged in with the creds of matt, Then I googled for its exploit and I found a Metasploit module. It was an authorized remote code execution.we can do this with burp suite also, I already wrote a blog on that.
