Inserting code into the comments of a valid image file is also possible. Milw0rm has a video on it. The video uses a LFI along with code inserted into the comments of a valid image file to deface a site. I'm not including the link as those who are interested can easily find it. -----Original Message----- From: listbounce@securityfocus.com [mailto:listbounce@securityfocus.com] On Behalf Of whitehat Sent: Wednesday, February 20, 2008 11:44 AM To: pen-test Subject: Malicious file upload in .JPG or GIF format Dear List, I'm doing Web Application Pen-Testing. In one of the pages there is an option to upload an image(.JPG or .GIF). How a hacker can exploit it and what are the chances of uploading a malicious .exe file (virus kind of stuff) in .JPG or .GIF format by changing its extension.
