This repository contains a local privilege escalation exploit for macOS (OS X), targeting CVE-2016-1757. The exploit is implemented in C and is split into two main components: a server (mach_race_server) and a client (mach_race_client). The server sets up a Mach IPC service and attempts to race the client process during the execution of a SUID or entitled binary, exploiting a race condition in the Mach port handling to inject shellcode into the target process. The shellcode sets the UID to 0 and spawns a root shell. The exploit is operational and provides a working payload for both 32-bit and 64-bit targets. The README provides detailed usage instructions and example targets, such as /bin/ps (SUID) and system_shove (entitled binary). The exploit is effective on OS X versions up to El Capitan 10.11.3 and is fixed in 10.11.4. The codebase is well-structured, with clear separation between client and server logic, and includes utility and IPC header files.
