Hi
I’ve been attempting this challenge but I’m stuck.
I setup cmsimple 3.0 and an old version of apache/php locally and I can upload files and access them via the exploit, but I can’t do it for the challenge.
Any tips? What am I doing wrong?

nvm I managed to solve it! :D

can you help ?
did you succeed uploading your own file or this is kind of different approach
