Hi friends! Once again we are here with a new vulnerable lab challenge “Billu Box” .created by Manish Kishan Tanwar it mainly attacker need to escalate privileges to gain root access. You can download it from here.
Let’s breach!!!
Open the terminal in your Kali Linux scan your network using netdiscover command and hence from scanning result I got target IP 192.168.1.102
Then use nmap aggressive scan for port and protocol enumeration:
Nmap –p- -A 192.168.0.102
So here I found port 22 and 80 are opened for SSH and HTTP respectively.
Since port 80 is open so I explore target IP on browser but here I didn’t get any remarkable result.
Without wasting time I choose another tool dirb for directories brute force attack. To start brute force attack for directories
Awesome! We have stepped up in right direction and dug out many directories but when you will see the given screenshot there I had highlighted the “test” directories. So now I will go with test directory.
So when I open test.php file in the browser here I found a message “file parameter is empty please provide file path in file parameter” where file parameter is vulnerable to LFI.
Using hackbar tool which is Firefox plug-in and Taking advantage of LFI vulnerability I try to include index.php in file parameter from file=index.php
So when I open index.php file here I found another file c.php is included.
So again with help of hackbar I look for c.php file from file=c.php for further enumeration so that we can find some clue to exploit the target.
When I read c.php file here I got some information related to connected database and the highlighted text is reflecting like credential for database.
If you remembered the result of dirb tool here it had revealed another directory which is phpmy so therefore I will go with phpmy for further enumeration.
Then again taking advantage LFI I explore config.inc.php from file=/var/www/phpmy/config.inc.php
Last but not least we have finally achieve something very remarkable and in the given screenshot you can read from config.inc.php file I have found server’s login username and password root: toor respectively.
From port enumeration result we have found port 22 is open for ssh therefore I will try root: toor for ssh login. When I use these credential for ssh login successfully I got root access hence the given challenge is completed.
