Editorial machine #15 (Linux)

`Editorial` is an easy difficulty Linux machine that features a publishing web application vulnerable to `Server-Side Request Forgery (SSRF)`. This vulnerability is leveraged to gain access to an internal running API, which is then leveraged to obtain credentials that lead to `SSH` access to the machine. Enumerating the system further reveals a Git repository that is leveraged to reveal credentials for a new user. The `root` user can be obtained by exploiting CVE-2022-24439 and the sudo configuration.
