Try viewing the online version Dear Colleague, File Upload Vulnerability is an extremely interesting topic with various twists and turns such as - Content-Type Checks, Bypassing Blacklists, Double Extensions, Defeating Getimagesize() checks, Null byte injection, getting a Meterpreter on the box via File Uploads etc. I just wanted to share one of the interesting videos which I've made on this topic - "Defeating Getimagesize() Checks in File Uploads"       http://www.pentesteracademy.com/video?id=414 In the above video, we go step by step and uncover how we can embed a webshell into an image and have it executed by the remote server, even if it uses APIs like Getimagesize() to verify the presence of an image.
