This repository is a proof-of-concept exploit for CVE-2014-1303, a heap-based buffer overflow in WebKit (WebKitGTK 2.1.2), ported to Linux (Ubuntu 14.04). The exploit is triggered by visiting a malicious HTML page (exploit.html) with a vulnerable browser (GtkLauncher). The exploit uses JavaScript to manipulate memory and construct a ROP chain, ultimately achieving arbitrary code execution in the browser process. The payload includes a custom loader (written in C and assembled via the loader/ directory) that listens on TCP port 9023 for further payloads or commands. The exploit can also leak the process PID and dump the /dev filesystem. The repository includes a simple Python HTTP server (server.py) to serve the exploit and handle debug output. The main entry points are exploit.html (the exploit page) and server.py (the web server). The code is structured into JavaScript helpers for ROP and syscalls, a C loader, and server scripts. The exploit is intended for educational purposes and demonstrates advanced browser exploitation techniques on Linux.
