How it went

  1. 0
    nmap

    An nmap scan shows a medical services site that resolves to doctors.htb.

  2. 1
    message inject

    The portal is vulnerable to a server-side injection; a crafted message yields a reverse shell.

  3. 2
    shaun

    LinPEAS finds Shaun's password in a botched password-reset log; su to Shaun for the user flag.

  4. 3
    Splunk

    Splunk runs on the box; SplunkWhisperer2 with Shaun's credentials executes a payload as root.
