Description

Anytime I see a file upload form during an application test, my attention is piqued. In a best-case scenario, I can upload a reverse shell in a scripting language available on the webserver. If the application is running in PHP or ASP for example, it becomes quite easy. If I can't get a backdoor uploaded, I will attempt to try to upload an HTML page to get my own client-side javascript uploaded for XSS attacks.
