Authors:   Mehmet Önder Key


In my research, besides the use of a new technique as compressed file(hpi,deb,jar etc.) manipulation in the field of remote code execution; this includes implementing this on popular web apps and publishing this 0day at the time of presentation.In most web applications, uploading harmful files is allowed with the precautions taken in the file upload section. One of these protection methods is file hash,extension,head,type etc control mechanisms. However, in this presentation, you will see how we can add a file to the system that we can run the code remotely with compressed file manipulation, how we can become an authorized user in the system, and how to increase the privileges of the seized application user on a popular applications. You will be able to see both a new method and 0Day in the presentation.
