#BoxFriday30 - Retired (Medium)

Join us this week at HTB KE as we take on Retired, a medium-difficulty Linux machine that blends web exploitation, binary exploitation, and privilege escalation. We’ll start by exploiting a path traversal vulnerability to access a vulnerable internal service, then analyze a buffer overflow in a binary to gain initial access using ROP gadgets. From there, we’ll pivot to another user via a symlink attack, and finally escalate privileges by abusing an insecure use of `/proc/sys/fs/binfmt_misc/register`. This box is a great opportunity to explore a full exploitation chain from web to root—don’t miss it!
