We decided to enumerate the system for known usernames. rest We used the -p- option for a full port scan in the Nmap command. Firstly, we have to identify the IP address of the target machine. Although this is straightforward, this is slightly difficult for people who don't have enough experience with CTF challenges and Linux machines. We added another character, ., which is used for hidden files in the scan command. hackmyvm insecure file upload security pointers Also, its always better to spawn a reverse shell. Pre-requisites would be knowledge of Linux commands and the ability to run some basic pentesting tools. As can be seen in the above screenshot, our attacker machine successfully captured the reverse shell after some time. Here, we dont have an SSH port open. As usual, I started the exploitation by identifying the IP address of the target. Here we will be running the brute force on the SSH port that can be seen in the following screenshot. The results can be seen below: Command used: << nmap 192.168.1.11 -p- -sV >>. We used the ping command to check whether the IP was active. suid abuse Let's see if we can break out to a shell using this binary. 10. We decided to download the file on our attacker machine for further analysis. And below is the flag of fristileaks_secrets.txt captured, which showed our victory.
