LaCasaDePapel is an easy difficulty Linux box, which is running a backdoored vsftpd server. The backdoored port is running a PHP shell with disabled_functions. This is used to read a CA certificate, from which a client certificate can be created. The HTTPS page is vulnerable to LFI, leading to exposure of SSH keys. A configuration file can be hijacked to gain code execution as root.
