Hack the Box (HTB) machines walkthrough series — Help

Today, we will be continuing with our exploration of Hack the Box (HTB) machines as seen in previous articles. This walkthrough is of an HTB machine named Help.

HTB is an excellent platform that hosts machines belonging to multiple OSes. It also has some other challenges as well. Individuals have to solve the puzzle (simple enumeration plus pentest)  in order to log into the platform and download the VPN pack to connect to the machines hosted on the HTB platform.

Note: Only write-ups of retired HTB machines are allowed. The machine in this article, named Help, is retired.

<<gobuster -u -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -t 30>>

8. Enumerating this directory gives a nice support HelpDeskZ portal page.

9. Directly searching for any HelpDeskZ exploit found a hit which is related to a file upload chained with RCE.

10. It also looks like this exploit was available on Searchsploit. So we’ll copy that to the (Read more...)
