How to Use Exploits Written in C Code

Hi everyone this is my first post in this lovely forum and unfortunately it's a question, I know it's not a good start, but I'm really stuck in this CTF VM and hoping you can help me with this issue.

I'm trying to improve my skills by download some CTFs and try to PWNED them this time my target machine running Apache/2.2.9 (Ubuntu) PHP/5.2.6-2ubuntu4.6 with Suhosin-Patch and after the research I found this exploit in exploit-DB site https://www.exploit-db.com/exploits/29290/ however I don't have a clue how to run this exploit!

I think i have to make changes here but i don't know how!

so can anyone help me with this?
