Exploiting the Starcraft 1 EUD Bug
Starcraft, released in 1998, is still one of the best strategy games ever made. Over 20 years later it still has a strong community and a remastered version was released in 2017 with updated graphics and sound. However, like most software, it has had it fair share of bugs. One of these bugs was an arbitrary read/write vulnerability in the parser for the scripts embedded in the maps of the game. As long as I’ve known about the bug I had assumed it could be used for exploitation but I had never seen a public example of this. Last weekend, I sat down and wrote an exploit myself and also turned this into a challenge for the Midnight Sun CTF 2020 qualifiers. In this first blog post I will go through some background, explain the bug and the exploit I wrote for it. In part two I will explain how I turned this into a CTF challenge and some of the solutions the teams came up with.
