STB 2018 Writeup

This is a write-up of the 2018 STB challenge: https://github.com/securifybv/spotthebug/tree/master/STB_2018

When first opening the repository, I see two interesting files; a PHP file, and a C++ file.

The C++ file: quick overview

The C++ has a BaseCGIClass (which has no functionality), and two children classes of the BaseCGIClass. I immediately notice the std::system call in the Executor class. The Logger class seems to not have any potential side effects. In the main function, I assume the Cgicc is an interface for the CGI protocol. This means formData("encryptedData") likely returns user input. We can control this.
