Simple Google searching, we found another exploit here. We got OS information. Hmm, useful, save it as systeminfo. Create a exe file using msfvenom. For some reason, I was not able to execute exe if I get it from the shell, so I used a python script to download executable and ran it. For this box, I used MS as before. I get it from here. Remember, it is a good practice to compile your own binary. This may not be the intended way but I did this way. Feel free to mention alternative ways other than ippsec walkthrough.

Start your free trial. Today, we will be continuing with our exploration of Hack the Box HTB machines as begun in the previous article. This walkthrough is of an HTB machine named Sunday. HTB is an excellent platform that hosts machines belonging to multiple OSes. It also has some other challenges as well. Note: Only write-ups of retired HTB machines are allowed. The machine in this article, named Sunday, is retired. We will adopt the same methodology of performing penetration testing as we have used previously. OK, so if we get the username from fingerwe can then try to log into the box. As we can see using finger on the box, it says that no user is logged on. To dig more into this box, we can use the enumeration script found here. Perl scipt. We can confirm these users with finger as well. So my last resort is to guess the password. Ssh sunny Below is an example. Browsing more into Sunny, we can see there is a backup directory which contains the agent22 and shadow. As we can see below, these belong to SHA and method Running hashcat on the collected hashes like below: Hashcat -m htb. Capture the user. We can use the wget —post-file parameter to post the contents of root. We spin up a Netcat listener on port 80 on our attacker machine. Now we can see that with just one command, Sammy becomes root and take complete control of the box. This is an interesting box.

HTB is an excellent platform that hosts machines belonging to multiple OSes. It also has some other challenges as well. Note: Only write-ups of retired HTB machines are allowed. The machine in this article, named Hawk, is retired. We will adopt the same methodology of performing penetration testing as we have used previously. As we can see, we have ports 21, 22, 80 and open. Running the Nmap scan indicates that it is a H2 service. It looks like an anonymous login worked on this box. Enumerating the directory contents reveals a. Transfer the file to the attacking box. The above file type can be easily brute-forced using a utility mentioned here. As shown below, the binary was built first and then run to perform the brute-force option. It reveals the password of the portal. Since we have also discovered port 80, below is the landing page. Make sure to save the filter as well. Add the PHP one-liner, as shown below:. Save the page text format as PHP code. Note that this option will only appear if point 12 is followed. Enumerating to grab the user. As is stated in the series, one of the checks to perform is to see what processes are running as root. Here we have the H2 service running as root. This service was also discovered during the initial Nmap scan.

This post documents the complete walkthrough of Networked, a retired vulnerable VM created by gulyand hosted at Hack The Box. If you are uncomfortable with spoilers, please stop reading now. Nothing unsual with the open ports. Let's do one better with nmap scanning the discovered ports to establish their services. Looks like we have only the http service to explore. Looks like the backup of the PHP files present in the site. If the acutal upload. As long as the extension ends with one of extensions, we should be able to upload a PHP file with double extension, e. The creator was kind to leave ncat installed. We can simply use that to give us a reverse shell. On my nc listener, a reverse shell comes knocking. This is easy to exploit. We can simply touch a file with a file name that begins with ; to separate sendmail from the command that we want to execute. Three minutes later, a reverse shell as guly appears in my nc listener. Let's upgrade our shell to full TTY. The file user. During enumeration of guly 's account, I notice guly is able to run the following command as root without password. Firstly, all the network scripts are written in bash. Furthermore, the single space character is allowed in the regular expression. Space is recognized as one of internal field separators or IFSwhich in this case really plays to our advantage, as you shall see. Any of the variables can be used to execute a command in the second field separated by a single space. Getting root.

I will hereafter describe the steps that I took to solve the Bashed challenge and end with some brief reflections on how the content of the challenge could apply to reality. In the grand scheme of hacking challenges, this one is quite simple. There might not be a lot here for an advanced operator to dig into. Nonetheless, Bashed is entertaining and a good way for beginners to discover some enumeration and hacking techniques, so I'll continue. This command tells me which TCP ports are open, attempts to discover which specific software versions are bound to those ports, and uses nmap's default set of NSE scripts to perform some basic enumeration of the discovered services. Note the useful tidbit provided by nmap's http-title script: this appeared to be a development website. Good to know. UDP scans revealed nothing. With only one service exposed on the box, it was obvious that enumerating the web content hosted on port 80 would be the next step. I first browsed the web content manually to see what I could see: A developer was blogging about developing a penetration testing tool on the same server that hosts this web content. Although not a substitute for more comprehensive tools like dirb and DirBusternmap's http-enum script is a fast and simple forced browsing utility capable of discovering web directories with common names. I often run it as part of a scripted reconnaissance process to see if it will produce any quick finds I can investigate while one of the aforementioned slower tools runs in the background. In this case, it actually discovered all of the content that was the key to compromising the target: In a real scenario, I'd eventually want to check all of the above directories and see if they contain vulnerable content or sensitive information. Let's navigate to it and see. Okay, so phpbash is basically a web shell that allows me to run arbitrary Linux system commands on the webserver and view the results. Obviously this could be used to compromise the system. In a real-world pentest, you'd probably use this initial command execution to place your own shell or backdoor on the system and execute it, as you never know when someone might take this web shell down, take the web daemon down, etc. However, for the purposes of this challenge, I found it okay to just continue using this shell. Based on the commands I ran above, I already had the gist of where a bit Ubuntu system and who an unprivileged web daemon account I was. Next, I wanted to get my bearings a bit and search for basic privilege escalation vectors. One of the first things I always check on that front is the sudo configuration of my user account. This indicates that I could run commands as the scriptmanager user. I kept that in the back of my head as I continued looking for interesting files on the system. It wasn't long before a huge reward was presented: How convenient. This means the script runs every minute. The owner of the file is scriptmanager. I could effectively become scriptmanager, so I could modify the script. Again, in reality, you'd use this vulnerability to run a shell or backdoor with root privileges and demonstrate that you effectively control the system. Our goal in this challenge is simply to show that we could have controlled the system by doing something that only the root user could do. I solved the root portion of the challenge using the method shown below. It was a little heavy-handed, but it was quick and effective. This series of commands overwrote test. This command dumped the contents of root. That's all for this one! We've retrieved both flags and solved the challenge. Lessons Learned The scenario laid out in this challenge is exaggerated in many regards. I imagine that finding a ready-to-use shell waiting for you on a system in the real world would be akin to finding a unicorn.

After a road game last week, don't be shocked if the Vikings trip up. Carolina's defense will make things difficult on Case Keenum and Cam Newton will win this one with his legs. The Bengals technically are still in the AFC playoff race. That'll last at least another week. My upset of the year: Cleveland gets a win. As everyone waits for Aaron Rodgers to return, the Packers stumble on the road one week after an overtime game. Houston doesn't have many more opportunities for wins. This is one of them against a team in the midst of a back-to-back on the road. Expect a close one. I'm refusing to totally jump ship on the Chiefs. Andy Reid is too good of a coach to let this season slip away. Alex Smith and Co. The Lions aren't good enough, but they'll give fans some hope with a win over a poor Bucs team that likely will be looking for a new coach soon. I keep waiting for the other shoe to drop with a Titans team that looks far worse than its record. A proud Cardinals team can be the group to knock them off. QB power rankingsNew York Jets (-1) at Denver BroncosImagine telling someone before the season that the Jets would be road favorites in Week 14. It's with good reason. If logic wins out, the Chargers will win the AFC West, host a playoff game and walk into Pittsburgh or New England in the Divisional Round as a dangerous team. Logic rarely wins out with the Chargers. Philadelphia Eagles at Los Angeles Rams (-2)Get your popcorn ready for this one. Two of the best teams in the NFC. The two top quarterbacks (and overall players) selected in the 2016 NFL Draft. Coach of the Year candidates. Los Angeles' great special teams unit will make a big play, but Carson Wentz will bounce back to lead a game-winning drive. It's impossible to feel confident in taking Blake Bortles in a game he's laying points to Russell Wilson. Earlier this season, Pittsburgh blew the doors off Baltimore. The Ravens bring a big-time defense to this one and will keep it close. It's amazing how many bad prime time games Miami has been in this year.
