Shoutout to [MuirlandOracle](https://muirlandoracle.co.uk/) for reaching out to me for help regarding dockerising this CVE. MurilandOracle has released a room on [TryHackMe](https://tryhackme.com/room/sudovulns) where this CVE is exploited and explained - he does an excellent job of explaining how it works.

I highly reccommend you check out the room specifically - but moreover the [TryHackMe](https://tryhackme.com) platform itself.
