Maximum Overkill: ROP exploit for Tinysploit

A while ago, someone posted a link to Tinysploit in the IRC channel of #vulnhub. It's an easy challenge, geared towards exploit development. In it, you'll find a vulnerable http server which can be exploited by a simple buffer overflow. The stack is set to executable. This is pretty easy, so instead I wanted to see if I could build a ROP exploit for it.
