Effective Modern CMake

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

MathSH Writeup

MathSH was a very innovative challenge in the category sandbox escape. Three members of our team - ALLES! - worked for several hours and eventually drew first blood on this challenge. This writeup is split into several parts, namely: dumping the binary, analysing the sandbox, gaining a better primitive for code execution and finally escaping the sandbox.

The description Calculator as a Service (CAAS) already hints to CAS, a legacy .NET technology to run code in various level of trusts.

We are given a restricted "shell" to calculate math expressions:
