Cache,a Linux box created by HackTheBox user ASHacker, was an overall medium difficulty box.The Initial enumeration is finding a domain hms.htb which is running a openemr which has a a SQLi which can give us a hash,cracking the hash and it also have a RCE which give us a shell. We also had a cred from the cache.htb. Using that we can su to get user. Enumerating in the shell we see memcached is running from which we can grab the password for second user luffy.su to that we see luffy is a memeber of docker group using that we can get root.
