| Date: | Thu, 14 Jun 2007 15:35:54 +0200 |
Various web applications, such as blogs, forums and photo galleries allow users to upload files. Providing file upload function without opening security holes proved to be quite a challenge in PHP web applications. The applications we have tested suffered from a variety of security problems, ranging from arbitrary file disclosure to remote arbitrary code execution. The paper describes various security holes occurring in file upload implementations and suggests a way to implement a secure file upload. The paper can be downloaded from http://www.scanit.be/uploads/php-file-upload.pdf Regards, Alla Bezroutchko Scanit http://www.scanit.be/ _______________________________________________ Full-Disclosure - We believe in it.
