Computer Security Project 3 Due: November 20, 2017, 11:59PM Version 1: November 6, 2017 Background \The Great Firewall of China" is notably misnamed. Rather than being a true rewall (an in-path device that can drop tra c), it is an on-path device that can only examine network tra c and respond by injecting either TCP RST packets or DNS replies.

Question 3: Polaris Main Idea: In order to exploit the vulnerability of the Polaris satellite, we were required to first leak the stack canary. Once we knew the exact value of the canary, we were able to treat the exploit like a standard buffer overflow problem, with the only difference of resetting the original value of the canary. Magic Numbers: In order to leak the stack …

An End-to-End Encrypted File Sharing System. In this project, you will apply the cryptographic primitives introduced in class to design and implement the client application for a secure file sharing system. Imagine something similar to Dropbox, but secured with cryptography so that the server cannot view or tamper with your data.

Story This project has a story component, denoted in blue boxes. Reading it is not necessary for project completion.\n Problem 3: jz \n Main Idea \n. The vulnerability lies in the fact that the canary value can be found through the printf statement in dehexify.Specifically, the while loop in dehexify will automatically increment i by 3 if it encounters the '\\' and 'x' next to one another. Therefore, it is possible to skip over the null terminator character inside of c.buffer if \"\\x\" is placed …To work with this option, you will need an EECS instructional account (you should have set one up in HW1, Q2.2).

The backend for this project exclusively uses single quotes for SQL queries. It is possible to select constants in SQL rather than selecting column names. For example, SELECT 1, 'foo', 'evan' will return a single row with 3 columns, with values of 1, 'foo' and 'evan'. You may find this useful if you can guess the format of the rows being ...
