HTB Academy: FILE UPLOAD ATTACKS - Skills Assessments

I think I understand how to move forward in the assessment but I don’t understand how to bypass the base64 so my commands never execute.

Hi, thank you for hints. Stacked on this task for last 2 days. But reviewing “Reverse Double Extension” module helped a lot.

This one took forever… All because of a stupid typo in my XXE. lol If I have any advice on this one it would be check you XXE for typos if you can’t get it to go through and use ZAP for fuzzing. It saved me a lot of time.

No matter what extension(s), content-type I try, I’m can’t seem to get past, “Only images are allowed.” Someone today told me they successfully uploaded the file using shell.phar.jpeg, but it won’t work for me. Help…
