This guide, which explores a virtual embedded Linux system similar to those used in real-world devices like set-top boxes, access points, vending machines, and modems. The guide begins with an introduction to this platform, followed by a static analysis of part of the firmware image. It then covers exploiting a command injection vulnerability, demonstrating how insights from the static analysis can be leveraged to gain root access on the virtual device.
