What are the common pitfalls and mistakes when implementing file upload features in web applications?
In systems where the original file name is used in the converted file name, it often becomes possible to find an input that both supports file upload (e.g., photos, avatars, videos, etc.) and uses some kind of command line shell (e.g., ImageMagick, ffmpeg, etc.) to process the file. In these cases, uploading a file with a name similar to "; linuxcommand -param; imagemagick .jpg" would allow you to execute commands such as Netcat and create reverse shells. Since often these scripts need escalated permissions to run, the shell will be created with elevated permission too. I recommend using a hash algorithm and then doing a manipulation on the result to ensure a directory structure without hash collisions and limited files per directory.

The project spanned four months and involved coordination between an outside creative agency to build the microsite as well as over three dozen internal stakeholders across content, production, engineering, creative, display acquisition, engagement and product marketing.
