So we can create a reverse shell task as root and hopefully obtain our flag! We follow the steps that are given to us by gtfobins and.Īnother one bites the dust! We'll see you next time! This will allow us to bypass the requirements for creating a Unit.
So we do some googling around and find this. While parsing through the LinEnum outputs, we see this line:
NETCAT REVERSE SHELL TASK DOWNLOAD
Now that I can ssh into the box, we download LinEnum.sh to the machine and see what pops up. Alternatively you can echo your key to the file if it already exists.
NETCAT REVERSE SHELL TASK FREE
The shells on the free box have been quite flakey so to hopefully mitigate this, I generated a new id_rsa.pub file and copied it to the box for easy ssh access. Now that we're logged in as pepper, lets snag our user key and move onto root! So we'll initiate a netcat session: nc -lvnp 4444Īfter we run it, we see our netcat session light up! We've obtained user! So in the end we have something like this: sudo -u pepper /var/www/Admin-Utilities/simpler.py -p We'll then use Command Substitution within the python program to call thsi script. The first thing we'll do is a create a small script to initiate a netcat connection back to us. We can use command substitution since the $ is not forbidden. However, since & is forbidden as well as most standard concatination commands we'll need to be a little bit more creative. This would tell the os to ping an ip of 1 and then execute our malicous command. So normally, we would be able to issue something like simpler.py -p 1 &. This is a text book command injection, with a twist. So turns out that the shell I was getting from SQLMAP was sending some odd terminal characters in the blank space?! So, I created a quick MSFPayload with MSFPC for a php reverse shell and everything was easy from there out! No matter how many times I attempted to run the program, i would get EOF errors: EOF Error?! Now this is where I was having issues with the program. When we do we see this function, exec_ping() that correlates to the -p command of the script. The script seems to give us some info on who would be considered an attacker. When we do we're greeted with a command screen: When we run the python app as us, we can't.
NETCAT REVERSE SHELL TASK MANUAL
We try to do some manual enumeration and see that there is a file we can run, simpler.py. It worked, we get a shell as We see that there is a user called Pepper, but we can't access the user.txt file. We'll issue sqlmap -u -D hotel -os-shell -no-cast. Next we'll use SQLMAP -shell functionality to see if we can create a reverse shell. We know that there is a phpmyadmin console running from enumerating the web service with dirbuster and the default word list.
NETCAT REVERSE SHELL TASK CRACKED
The cracked password for the phpmyadmin DBAdmin account.
NETCAT REVERSE SHELL TASK CRACK
SQLMAP will offer to crack the password for us, so why not. Once we've dumped the table we have a user of DBAdmin. We issue sqlmap -u -D mysql -T user -dump The -D is for Database, the -T is for Table and well we know what -dump does. Now that we've dumped the mysql table, lets dump the user portion of it. We will check the tables of the 'mysql' database by issuing sqlmap -u -D mysql -tables. Now that we've run our mapping successfully, we get back a list of databases. We run sqlmap -u -dbs -no-cast We have to use -no-cast to convert our null values becuase the service running will likley ban us due to injection attempts.
We actually get banned for 90 seconds by issuing '1=1'". We can run some manual SQL injections against it to test.
When we click on room 1 and wee it references ?cod=1 This might be injectable. There's a good chance that we can exploit some PHP. The first thing we notice is that the rooms page sends us to rooms-suites.php. Many of the links are dead, but the rooms are not. So the first thing we do is to head over to the http port and see what's being hosted. Service Info: OS: Linux CPE: cpe:/o:linux:linux_kernel |_http-server-header: Apache/2.4.25 (Debian) The first things we do is our standard nmap command nmap -sC -sV -oA jarvis 10.10.10.143 We get back a small result Nmap scan report for 10.10.10.143Ģ2/tcp open ssh OpenSSH 7.4p1 Debian 10+deb9u6 (protocol 2.0) After I figured out that was the problem it was easier.
This box was a total pain in the ass due to the way my reverse shell was terminating lines. Today we're going to do the machine Jarvis on Hack the Box.
