    This blog post should be useful for those who also know how SharePoint works: - I've shown how code injection can aid to bypass some misconfigs in .NET + some thoughts for actual bypasses if you've research time!

    I have had this question of why we cannot get a shell when we can create files in our directory. I thought it is a well-known thing, but do you know why? (I like to see if it can be a blog worthy topic in 2020) 🍻
