This CVE affects all versions of sudo under 1.8.28 where a sudo user can escalate to root by referencing its user ID.

This Dockerfile allows this CVE to be built, where it can be used for CTF's and demonstrations for example.

Shoutout to MuirlandOracle for reaching out to me for help regarding dockerising this CVE. MurilandOracle has released a room on TryHackMe 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 platform itself.
