Summary
Onetwoseven,a Linux box created by HackTheBox user jkr, was an overall hard difficulty box.I really enjoy this box.The foothold for this Linux box craftily utilizes symbolic links and port forwarding through sftp to gain access to the admin interface. This ultimately leads to RCE and a shell after some addon-based web exploitation. For escalating to the root user, we take advantage of the available apt sudo commands while performing a man-in-the-middle package injection via http-proxy.
