This repository is a proof-of-concept (PoC) exploit for CVE-2019-12594, a sandbox escape vulnerability in DOSBox 0.74-2. The repository contains three files: a README.md describing the vulnerability and usage, a batch file (make_mem.bat) for compiling the exploit, and the main exploit code (mem.c) written in C. The exploit works by mounting the host's /proc/self/ directory into DOSBox as drive P:, then manipulating the host's memory via specially crafted file operations on p:\mem and p:\maps. It constructs a ROP chain to execute arbitrary commands on the host system as the user running DOSBox. The provided payload launches the 'qalculate-gtk' calculator application as a demonstration. The exploit targets local environments where DOSBox is run on Linux, and requires the user to mount /proc/self/ into DOSBox. The main attack vector is local privilege escalation/sandbox escape. The code demonstrates a deep understanding of memory manipulation and process control, and is a functional PoC for the referenced CVE.
