This repository contains a local privilege escalation exploit for macOS targeting CVE-2023-32428. The main file, 'badmalloc.c', is a C program that abuses the crontab binary and the MallocStackLogging feature to manipulate file system structures and ultimately write a malicious configuration file to /etc/sudoers.d/. This file grants passwordless sudo access to all users, effectively allowing a local attacker to escalate privileges to root. The exploit works by creating a specific directory and symlink structure, repeatedly swapping directories, and hijacking the EDITOR environment variable to inject the payload. The repository consists of a single exploit source file and a minimal README. The exploit is operational and provides a working local privilege escalation on vulnerable macOS systems.
