This repository is a small standalone proof-of-concept lab for CVE-2023-36664, a Ghostscript command-execution issue caused by unsafe handling of pipe device paths such as %pipe%. The repository contains four files: a Dockerfile that builds a vulnerable Ubuntu 22.04 environment with Ghostscript 10.01.1 from source, a docker-compose.yml that runs the lab container with host networking and X11 socket access, a README explaining the vulnerability and reproduction steps, and poc.py, the main exploit component. The exploit logic is in poc.py. It is not an automated remote exploitation tool; instead, it generates a malicious PostScript or EPS file containing a crafted Ghostscript expression: '(%pipe%<command>) (<mode>) file /DCTDecode filter'. The command portion is fully user-controlled via CLI arguments, making the PoC flexible for arbitrary command execution once the generated document is processed by vulnerable Ghostscript. Supported output formats are .ps and .eps, and the operator can choose file mode r or w. The repository’s demonstrated capability is arbitrary OS command execution triggered through malicious document parsing. The included lab scenario uses a command like 'gedit /var/www/html/config.php' to show local file disclosure of a planted secret (DB_PASSWORD=SuperSecret1234!!!). This means the exploit can be used both for code execution and for indirect access to sensitive local files, depending on the supplied command. Attack delivery is primarily file-based: an attacker must get a vulnerable Ghostscript instance to open or process the generated PS/EPS file. The README also shows execution with 'gs -dNOSAFER test.ps', though the vulnerability itself targets Ghostscript’s path validation around pipe syntax in vulnerable versions. Overall, this is a real exploit PoC with a basic but customizable payload generator, suitable for lab reproduction rather than large-scale weaponized use.
